sew.

477
00:22:39,210 --> 00:22:42,170
Allura qabel ngħaddu tagħna

Hi darb'oħra, kulħadd.

484
00:23:02,440 --> 00:23:03,610
Jisimni Scaz.

485
00:23:03,610 --> 00:23:06,860
Stajt ġiet tagħlim fil-Yale mill-2001.

486
00:23:06,860 --> 00:23:10,820
U meta I am not tagħlim,
riċerka tiegħi huwa fi robotika

487
00:23:10,820 --> 00:23:12,620
u intelliġenza artifiċjali.

488
00:23:12,620 --> 00:23:17,700
>> U l-aħbar li għandi llum
huwa li tibda fi ftit ġimgħat,

00:23:17,700 --> 00:23:22,170
aħna qed tmur biex ikunu qed idaħħlu xi
materjal supplimentari li CS50 biex jitkellmu

490
00:23:22,170 --> 00:23:24,510
dwar is-software intelliġenza.

491
00:23:24,510 --> 00:23:28,230
Aħna qed tmur biex jitkellmu dwar kif
postijiet bħal Netflix u Hulu

inti tista 'tixtieq li tara.

493
00:23:31,780 --> 00:23:35,710
Fejn aħna ser nitkellmu dwar kif
karozzi-sewwieq inqas attwalment jaħdmu.

494
00:23:35,710 --> 00:23:39,020
U aħna ser tkun tista 'art
dawn l-affarijiet fil-kunċetti

495
00:23:39,020 --> 00:23:41,730
li int tagħlim
f'din il-klassi llum.

496
00:23:41,730 --> 00:23:45,410
>> Minħabba kollha ta 'dawn l-affarijiet huma
mibnija fuq l-istess fondazzjoni.

497
00:23:45,410 --> 00:23:47,396
U dan huwa dak li din
serje se tesplora.

I sfortunatament marru għall
Harvard bħala Undergrad.

504
00:24:03,540 --> 00:24:07,020
Li għaddej biex tikseb maqtugħa
mill-kurrent attwali.

505
00:24:07,020 --> 00:24:09,870
>> U issa jien hawn bħala lecturer fil
dipartiment xjenza tal-kompjuter.

506
00:24:09,870 --> 00:24:14,825
U jien tgħin run-kors
ma Scaz, David u Andy.

507

00:24:31,770 --> 00:24:35,240

514
00:24:35,240 --> 00:24:37,930
UI kien wieħed minn dawk gidjien
fejn, meta Wasalt biex Yale,

515
00:24:37,930 --> 00:24:42,030
I really ħasbu li nixtieq qatt
għandek tfittex lejn numru qatt darb'oħra.

516
00:24:42,030 --> 00:24:46,240
U mbagħad I induna li għandek bżonn
kemm ta 'xjenza u QR krediti lill-gradwati.

517
00:24:46,240 --> 00:24:51,340
U hekk rebbiegħa freshman tiegħi, I ħa
klassi, a CS, intro klassi CS hawn

518

fil-Yale.

519
00:24:52,230 --> 00:24:54,710
I kien simili, dan huwa simili
attwalment pretty jibred.

520
00:24:54,710 --> 00:25:01,330
>> U filwaqt I attwalment ended up li tiddikjara
Bħala kwistjonijiet globali ewlenin, il-ħiliet

521
00:25:01,330 --> 00:25:04,910
I mgħallma fl CS u l-ipprogrammar
huma tant applikabbli għal kwalunkwe qasam

522
00:25:04,910 --> 00:25:05,970
inti tagħżel li tagħmel.

523
00:25:05,970 --> 00:25:09,770

DAVID J. Malan: Grazzi.

530
00:25:20,380 --> 00:25:22,940
Hekk biss qabel klassi beda,
kellna l-opportunità

531

xi selfies fil-forma video ta 'verament
ewwel tour tiegħi ta 'kampus Yale hawn.

533
00:25:30,530 --> 00:25:35,420
U hekk ħsibna aħna'd jaqsmu rough
qatgħa tal eżattament dan bħala Scaz u Andy

Imma jien issa li l-TD hemmhekk.

574
00:26:58,485 --> 00:26:59,860
U li kkunsidrat off-kampus.

575
00:26:59,860 --> 00:27:03,659
>> -Here Għandna arkitettura Gotiku.

576

Famużi fid-dinja.

577
00:27:04,200 --> 00:27:06,758
Għandna xi arkitettura aktar Gotiku.

578
00:27:06,758 --> 00:27:10,614
U l-kostruzzjoni, u
aktar arkitettura Gotiku.

579
00:27:10,614 --> 00:27:11,114
Hi.

580
00:27:11,114 --> 00:27:15,470
Dan huwa fejn aħna qed wara ħinijiet tal-uffiċċju
Tlieta permezz Ħamis fil Hogwarts,

581
00:27:15,470 --> 00:27:16,922
kif [inaudible].

582

00:27:22,078 --> 00:27:24,030
Aħna fil-Yale University ta
Iskola liġi, fejn

586
00:27:24,030 --> 00:27:25,870
lecture lum hija ser iseħħ.

587
00:27:25,870 --> 00:27:29,220
Ejja ras.

588
00:27:29,220 --> 00:27:30,375
>> [END Daqq]

li twassalna hawn issa.

590
00:27:32,370 --> 00:27:38,040

591
00:27:38,040 --> 00:27:40,770
Allura s'issa, aħna kont qed
jiffoka fuq pseudocode,

592
00:27:40,770 --> 00:27:42,430
li huwa dan sintassi English-like.

593
00:27:42,430 --> 00:27:45,030
Hija għandha l-ebda speċifikazzjoni preskritt.

594
00:27:45,030 --> 00:27:47,030
Huwa biss tuża xi
lingwa intuwittivi jekk inti

595
00:27:47,030 --> 00:27:48,950
jridu jispjegaw dak li trid tagħmel.

596
00:27:48,950 --> 00:27:52,270
>> Imma ejja tibda issa biex transizzjoni
għall-kodiċi, kif ħafna nies jgħidu.

597
00:27:52,270 --> 00:27:54,880
Iżda aktar preċiż, xi ħaġa
magħrufa bħala kodiċi sors.

598
00:27:54,880 --> 00:27:58,210
Dan huwa l-lingwa li l-bnedmin
jiktbu li kompjuters ultimately--

599
00:27:58,210 --> 00:28:00,780
possibilment wara xi numru ta '
steps-- finalment jifhem

600
00:28:00,780 --> 00:28:02,530
sabiex tkun taf kif għandek tagħmel xi ħaġa.

601
00:28:02,530 --> 00:28:05,120
Li inti raw idea ta '
dan forsi l-Erbgħa.

602
00:28:05,120 --> 00:28:07,780
>> Dan huwa eżempju li
oerhört, underwhelming

603
00:28:07,780 --> 00:28:10,220
meta jitħaddmu sempliċiment jgħid "bonjour dinja."

604
00:28:10,220 --> 00:28:13,510
U huwa miktub f'lingwa imsejjaħ
C, li hija sintattikament simili ħafna

605
00:28:13,510 --> 00:28:15,676
għal lott ta 'lingwi oħra
li inti tista 'ma taf,

606
00:28:15,676 --> 00:28:18,409
iżda tista smajt ta 'prodotti simili Java,
u C ++, u Python, Ruby u,

607
00:28:18,409 --> 00:28:21,200
u simili, u tabilħaqq, aħna ser
iqattgħu ħafna mill-semestru li jużaw C,

608
00:28:21,200 --> 00:28:23,530
u mbagħad lejn it-tmiem tal-
semestru, huma msejsa fuqu,

609
00:28:23,530 --> 00:28:25,446
u l-introduzzjoni kwalunkwe
numru ta 'lingwi oħra.

610
00:28:25,446 --> 00:28:28,810
Fost dawn PHP, u JavaScript,
lingwa database imsejjaħ SQL.

611
00:28:28,810 --> 00:28:31,526
Iżda ma C, dak li aħna ser ikollhom
dan il-fehim minn isfel għal fuq

612
00:28:31,526 --> 00:28:33,900
ta 'eżattament kif il-kompjuters xogħol,
x'tista 'tagħmel magħhom,

613
00:28:33,900 --> 00:28:37,252
u kif tista 'ssolvi l-problemi
l-aktar effettiv billi dan

614
00:28:37,252 --> 00:28:39,460
saffi li aħna diskussi
nhar l-Erbgħa, u l-pożizzjoni

615
00:28:39,460 --> 00:28:40,870
fuq l-ispallejn ta 'oħrajn.

616
00:28:40,870 --> 00:28:42,200
Iżda aktar fuq li fil-ġejjieni.

617
00:28:42,200 --> 00:28:46,650
>> Illum aħna nħarsu lejn ambjent aktar sempliċi,
iżda fundamentalment identiċi

618
00:28:46,650 --> 00:28:49,970
ambjent magħrufa bħala Scratch mill
ħbieb tagħna fil MIT Media Lab.

619
00:28:49,970 --> 00:28:52,570
Din hija grafika
lingwa ta 'programmar, Scratch,

620
00:28:52,570 --> 00:28:54,330
fejn inti tista 'ttawwal
u qatra affarijiet li

621
00:28:54,330 --> 00:28:57,430
look like biċċiet puzzle li
biss jorbtu ma 'xulxin jekk tagħmel

622
00:28:57,430 --> 00:28:59,872
sens loġiku jew programmatiku li jagħmlu dan.

623
00:28:59,872 --> 00:29:02,330
Iżda li għaddej biex inessu
ikollhom konverżazzjoni dwar l

624
00:29:02,330 --> 00:29:04,604
tal-istess programmazzjoni
fundamentali li xi wħud minnkom

625
00:29:04,604 --> 00:29:06,520
tista 'tkun taf diġà, li
ħafna minnkom ma jista

626
00:29:06,520 --> 00:29:09,670
jafu xejn ta 'mingħajr
li staġnati franchement,

627
00:29:09,670 --> 00:29:13,150
fil-intellettwalment
sintassi uninteresting ta semicolons,

628
00:29:13,150 --> 00:29:14,950
u parentesi, u
kwotazzjonijiet, u simili.

629
00:29:14,950 --> 00:29:16,910
Kollha li, kmieni
fuq, huma distrazzjoni

630
00:29:16,910 --> 00:29:20,322
għal dak li huma interessanti
u l-ideat ġenwinament utli.

631
00:29:20,322 --> 00:29:22,280
Mela ejja tagħti quick
Ħarsa lejn l-ambjent

632
00:29:22,280 --> 00:29:24,180

Jew stenna sekonda waħda.

789
00:37:16,330 --> 00:37:17,834
Or play meow ħoss.

790
00:37:17,834 --> 00:37:20,500
U fil-fatt l-ambjent fil
li aħna qed tmur biex tkun qiegħda tagħmel din

791
00:37:20,500 --> 00:37:21,610
huwa msejjaħ Scratch.

792
00:37:21,610 --> 00:37:25,060
>> U jekk I pull up Scratch mingħajr
preloading kwalunkwe kodiċi attwali,

793
00:37:25,060 --> 00:37:27,830
ejja tagħti ħarsa lejn din
user interface, biex ngħidu hekk.

794
00:37:27,830 --> 00:37:29,730
Il-kontrolli li aħna jinteraġixxu.

795
00:37:29,730 --> 00:37:32,840
Fuq il-quċċata xellug hawn tad-
screen, taħt il-menus,

796
00:37:32,840 --> 00:37:34,650
għandna l-istadju, biex ngħidu hekk.

797
00:37:34,650 --> 00:37:36,550
Allura Scratch huwa dak li aħna ser sejħa Sprite.

798
00:37:36,550 --> 00:37:37,520
Huwa karattru.

799
00:37:37,520 --> 00:37:40,660
>> U huwa jista 'jiġi kkontrollat ​​mill
miktub programmi kontrih.

800
00:37:40,660 --> 00:37:43,950
U hu ser ikunu jistgħu jitilgħu u jinżlu
u tax-xellug u tal-lemin f'dan l-ambjent,

801
00:37:43,950 --> 00:37:46,075
mhux biss billi mexxew il-
ġurdien, iżda programmatically.

802
00:37:46,075 --> 00:37:48,930
I tista 'tgħidlu jimxu id-dritt, walk
xellug, up, down jew simili.

803
00:37:48,930 --> 00:37:51,440
UI tista 'tintroduċi oħra
sprites jew karattri kif ukoll.

804
00:37:51,440 --> 00:37:54,616
>> Tabilħaqq, fuq il-qiegħ hawnhekk huwa fejn
tkun taf tara lista tiegħek ta 'sprites.

805
00:37:54,616 --> 00:37:56,865
Fil-mument, I biss għandhom
wieħed, imma nista 'toħloq aktar,

806
00:37:56,865 --> 00:37:58,880
u dawn ser jidhru eżattament stabbiliti hemmhekk.

807
00:37:58,880 --> 00:38:02,630
Mela jekk inti Rewind għal mument, bħal
Oscartime-- per eżempju, Oscar,

808
00:38:02,630 --> 00:38:04,590
fuq ix-xellug, l-Trash
tista ', kien Sprite.

809
00:38:04,590 --> 00:38:07,450
U l-ħaġa fin-nofs, il-
riċiklaġġ bin, kien Sprite ieħor.

810
00:38:07,450 --> 00:38:09,300
U l-bin kompost kien Sprite ieħor.

811
00:38:09,300 --> 00:38:11,790
U kull biċċa ta '
żibel jew riċiklabbli

812
00:38:11,790 --> 00:38:14,590
li kien jaqa 'mis-sema
huwa wkoll Sprite, li kull wieħed minnhom

813
00:38:14,590 --> 00:38:16,150
kien ipprogrammat individwalment.

814
00:38:16,150 --> 00:38:17,040
>> Kif inti program?

815
00:38:17,040 --> 00:38:20,180
Well, hawn fuq dwar id-dritt
naħa tal-lemin huwa l-qasam skripts.

816
00:38:20,180 --> 00:38:22,930
U dan huwa fejn nistgħu
drag u qatra biċċiet puzzle.

817
00:38:22,930 --> 00:38:26,066
Fil-ġimgħa, li għaddej biex tkun
fejn aħna ekwivalenti jikteb il-kodiċi

818
00:38:26,066 --> 00:38:28,940
b'aktar minn keyboard, iżda għal
illum dan ser ikun sejjer u twaqqa

819
00:38:28,940 --> 00:38:31,680
biċċiet puzzle, il-
paletti li għalihom kollha jistgħu

820
00:38:31,680 --> 00:38:33,190
'jinstab hawnhekk lemin fin-nofs.

821
00:38:33,190 --> 00:38:35,190
Tabilħaqq, fin-nofs
hawn hemm mazz sħiħ

822
00:38:35,190 --> 00:38:37,910
ta 'kategoriji ta' puzzle
biċċiet jew blokki.

823
00:38:37,910 --> 00:38:42,500
One relatati mal-mozzjoni, tħares,
ħoss, pinna jitla 'u' l isfel,

824
00:38:42,500 --> 00:38:43,860
data, jikkontrollaw avvenimenti.

825
00:38:43,860 --> 00:38:45,654
Mhux pjuttost ċert għadhom
liema kollha ta 'dawn ifissru,

826
00:38:45,654 --> 00:38:47,820
imma inti ser tara li dawn ħadthom
ġew nicely kategorizzata.

827
00:38:47,820 --> 00:38:50,680
U jiktbu programm
Scratch, ejja nagħmlu eżattament dan.

828
00:38:50,680 --> 00:38:53,480
>> Jien ser tibda off taħt
Avvenimenti, u drag dan wieħed hawn.

829
00:38:53,480 --> 00:38:55,470
Meta bandiera aħdar għafast.

830
00:38:55,470 --> 00:38:56,704
Issa għaliex dan wieħed?

831
00:38:56,704 --> 00:38:59,120
Ukoll ifakkar li l-voluntiera tagħna
ħarāu, il-ħaġa ewwel I

832
00:38:59,120 --> 00:39:02,017
jew dawn ma kien ikklikkja li green
bandiera fir-rokna ta 'fuq tal-lemin.

833
00:39:02,017 --> 00:39:03,600
U dan ifisser biss jibdew il-programm.

834
00:39:03,600 --> 00:39:06,560
>> Allura meta jiġri il-każ,
dak li nixtieq do?

835
00:39:06,560 --> 00:39:10,070
Jien se jmorru taħt Jistenna,
u jien se tagħmel "jgħidu bonjour."

836
00:39:10,070 --> 00:39:14,000
U jien se jibdlu dan u
ngħid xi ħaġa bħal "Hello Yale."

837
00:39:14,000 --> 00:39:16,970
U issa jien ser zoom
out, ikklikkja l-bandiera aħdar,

838
00:39:16,970 --> 00:39:19,050
u voila, stajt bil-miktub program.

839
00:39:19,050 --> 00:39:20,990
Huwa mhux kollha li eċċitanti
għadha biss, iżda dan

840
00:39:20,990 --> 00:39:23,195
huwa eżattament fejn kull
ta 'dawk awtur beda,

841
00:39:23,195 --> 00:39:25,740
kemm mal Pikachu, u l
basal binarja, u Oscartime,

842
00:39:25,740 --> 00:39:26,890
u tant eżempji aktar.

843
00:39:26,890 --> 00:39:29,150
>> Tibda super sempliċi, u
imbagħad tibda saff,

844
00:39:29,150 --> 00:39:31,046
u żid fuq karatteristiċi u l-funzjonalità.

845
00:39:31,046 --> 00:39:32,920
Allura liema huma dawn saffi
ser jikkonsisti?

846
00:39:32,920 --> 00:39:36,086
Ukoll, lil hinn dikjarazzjonijiet, aħna ser wkoll
affarijiet li huma ftit aktar fancily

847
00:39:36,086 --> 00:39:38,910
imsejħa Boolean Espressjonijiet,
wara xi ħadd jismu BOOL.

848
00:39:38,910 --> 00:39:42,820
U espressjoni Boolean huwa sempliċement
espressjoni li huwa jew vera jew falza,

849
00:39:42,820 --> 00:39:45,740
iva jew le, 1 jew 0.

850
00:39:45,740 --> 00:39:47,480
>> Kwalunkwe opposti polari bħal dik.

851
00:39:47,480 --> 00:39:48,902
Huwa jew vera jew le.

852
00:39:48,902 --> 00:39:51,360
Iżda aħna qed wkoll ser tara
dawk li jistgħu jixbhu dan.

853
00:39:51,360 --> 00:39:52,925
Allura per eżempju, huwa l-maws 'l isfel?

854
00:39:52,925 --> 00:39:54,550
Huma qed tip ta 'mistoqsijiet, jekk inti se.

855
00:39:54,550 --> 00:39:57,650
>> Il-ġurdien huwa jew 'l isfel,
vera jew mhuwiex, falza.

856
00:39:57,650 --> 00:39:59,990
1 jew 0, jekk inti se,
tendenza li jkun l-immappjar.

857
00:39:59,990 --> 00:40:01,740
Veru huwa 1, falza huwa ta '0.

858
00:40:01,740 --> 00:40:03,740
Ukoll dak dwar inqas minn dan?

859
00:40:03,740 --> 00:40:05,400
Jew hekk, hija din inqas minn dan?

860
00:40:05,400 --> 00:40:06,650
Li l-kwistjoni ta 'tip.

861
00:40:06,650 --> 00:40:09,140
>> U jekk inti tpoġġi żewġ
numri fil hemm, jew x

862
00:40:09,140 --> 00:40:12,010
se tkun inqas minn y jew
daqs y, jew akbar minn y,

863
00:40:12,010 --> 00:40:14,635
iżda dan il-blokk Ser naraw, huwa biss
ser risposta għad-domanda,

864
00:40:14,635 --> 00:40:15,810
huwa dan inqas minn dak?

865
00:40:15,810 --> 00:40:17,650
Nistgħu anke tara xi ħaġa bħal din.

866
00:40:17,650 --> 00:40:18,790
Pointers ġurdien jmissux.

867
00:40:18,790 --> 00:40:21,610
Allura fil Scratch, tista 'titlob
il-kwistjoni, huwa l-Sprite

868
00:40:21,610 --> 00:40:22,800
tmiss il-mouse pointer?

869
00:40:22,800 --> 00:40:26,040
Kliem ieħor, hija l-jittajjar cursor
fuq l-għatu, jew l-ekwivalenti?

870
00:40:26,040 --> 00:40:28,100
>> Ser naraw affarijiet anding flimkien.

871
00:40:28,100 --> 00:40:30,970
Tista 'titlob żewġ domandi, u
kun żgur li t-tnejn

872
00:40:30,970 --> 00:40:34,920
jtik iva jew tweġibiet vera qabel
teħid ta 'deċiżjoni li tagħmel xi ħaġa.

873
00:40:34,920 --> 00:40:36,709
Iżda mbagħad kif inti tagħmel deċiżjonijiet?

874
00:40:36,709 --> 00:40:38,000
Well, aħna għandna dawn il-kundizzjonijiet.

875
00:40:38,000 --> 00:40:40,041
>> U rajna dan fil tagħna
Eżempju tal-ktieb tat-telefon.

876
00:40:40,041 --> 00:40:41,900
B'ħarsitha lejn ix-xellug jew
dritt għal Mike Smith.

877
00:40:41,900 --> 00:40:45,140
U fil-kondizzjoni, inti
jagħmel xi ħaġa potenzjalment,

878
00:40:45,140 --> 00:40:47,240
jekk espressjoni Boolean huwa veru.

879
00:40:47,240 --> 00:40:48,720
>> U fil-fatt, avviż l-forom issa.

880
00:40:48,720 --> 00:40:52,250
Hemm dan placeholder dritt issa
fuq il overhead fejn nistgħu fit--

881
00:40:52,250 --> 00:40:54,532
jekk I kontrina wieħed slide-- din il-forma.

882
00:40:54,532 --> 00:40:55,740
Mhuwiex pjuttost l-istess daqs.

883
00:40:55,740 --> 00:40:58,400
U fil-fatt, tkun taf tara li
Scratch resizes affarijiet dinamiku

884
00:40:58,400 --> 00:41:01,479
li jitwaħħal biċċiet puzzle, iżda l-
forma hija x'inhu importanti.

885
00:41:01,479 --> 00:41:03,270
Din ħaġa qisu
li, u tabilħaqq huwa

886
00:41:03,270 --> 00:41:05,410
bejn wieħed u ieħor l-istess forma
li għandha tiffittja fil hemmhekk.

887
00:41:05,410 --> 00:41:09,520
U jekk irridu nagħmlu xi ħaġa
B'dan il-mod jew b'dak il-mod, jekk jew inkella,

888
00:41:09,520 --> 00:41:12,080
għandna dan puzzle
biċċa Scratch ukoll.

889
00:41:12,080 --> 00:41:17,450
>> Issa ejja ngħidu li inti riedu
do jekk, inkella jekk, jew inkella.

890
00:41:17,450 --> 00:41:20,120
Fi kliem ieħor,
three-way furketta fit-triq.

891
00:41:20,120 --> 00:41:22,656
Well X'tista 'tagħmel
biss billi glancing fil dan?

892
00:41:22,656 --> 00:41:25,030
I tista 'tieħu din il-biċċa puzzle,
u ma jidhirx li taqbel,

893
00:41:25,030 --> 00:41:27,670
iżda għal darb'oħra, Scratch va
biex terġa 'daqs nicely għalina.

894
00:41:27,670 --> 00:41:29,940
I tista 'tibda saff
dawn l-affarijiet flimkien.

895
00:41:29,940 --> 00:41:32,900
>> Allura issa I jkollhom three-way
furketta jekk dan huwa minnu, jagħmlu dan.

896
00:41:32,900 --> 00:41:36,560
Else jekk dan il-ħaġa oħra huwa minnu,
jmorru b'dan il-mod, inkella jmorru b'dan il-mod ieħor.

897
00:41:36,560 --> 00:41:39,200
U fil-film Muppet, il
furketta fit-triq, biex ngħidu hekk,

898
00:41:39,200 --> 00:41:42,610
bejn Yale jew Stanford, kien
eżattament dak, biss żewġ kundizzjonijiet.

899
00:41:42,610 --> 00:41:45,190
Jew tmur b'dan il-mod, inkella jmorru mod.

900
00:41:45,190 --> 00:41:46,940
>> Ukoll, loops wkoll jeżistu fl-ipprogrammar.

901
00:41:46,940 --> 00:41:49,100
U konna użati dawn diġà fil
klassi u fil-kodiċi pseudocode,

902
00:41:49,100 --> 00:41:51,060
u żgur f'dawk
Programmi Scratch dejjem.

903
00:41:51,060 --> 00:41:53,730
Scratch għandha din il-biċċa puzzle li
se biss let inti tagħmel xi ħaġa dejjem.

904
00:41:53,730 --> 00:41:55,688
U xi kultant tixtieq
li jagħmel xi ħaġa dejjem.

905
00:41:55,688 --> 00:41:58,810
Mhuwiex neċessarjament bug, huwa
għaliex inti tixtieq arloġġ biex jibqgħu għaddejjin,

906
00:41:58,810 --> 00:42:00,730
jew logħba li jżomm playing.

907
00:42:00,730 --> 00:42:04,800
Jew inti tista 'tispeċifika numru finit ta'
passi, kif ma 'din il-blokka ripetut hawnhekk,

908
00:42:04,800 --> 00:42:06,550
li se jirrepeti xi ħaġa 10 darbiet.

909
00:42:06,550 --> 00:42:08,560
Nistgħu stabbilit varjabbli, aħna ser dalwaqt tara.

910
00:42:08,560 --> 00:42:12,300
U ma 'varjabbli, simili fl-ispirtu
li alġebra, bħall x, y jew, jew z.

911
00:42:12,300 --> 00:42:16,390
Hija xi ħaġa simbolika li jista 'jaħżen
xi valur, xi biċċa informazzjoni,

912
00:42:16,390 --> 00:42:18,320
li inti tista 'tixtieq
li tiftakar għal aktar tard.

913
00:42:18,320 --> 00:42:21,080
>> Aħjar eżempju ta 'dan jista' jkun
logħba fejn għandek punteġġ,

914
00:42:21,080 --> 00:42:22,080
bħal fil Pikachu.

915
00:42:22,080 --> 00:42:25,180
Kemm biċċiet ta 'kejk
u whatnot ma inti qabda?

916
00:42:25,180 --> 00:42:29,340
Ukoll, li jista 'jkun fattur varjabbli
imsejħa punteġġ li jibda b'0.

917
00:42:29,340 --> 00:42:32,400
U mbagħad kull darba li aħna maqbuda
biċċa kejk jew kandju, jew simili,

918
00:42:32,400 --> 00:42:33,720
jiġrilha inkrementat.

919
00:42:33,720 --> 00:42:35,990
Hija gets miżjuda ma wieħed kull darba.

920
00:42:35,990 --> 00:42:38,450
U stores hekk varjabbli a
biċċa informazzjoni bħal dik.

921
00:42:38,450 --> 00:42:41,450
Imbagħad hemm arrays, u aħna ser jiġu
lura għal dawn fil-ġimgħa jew tnejn ħin,

922
00:42:41,450 --> 00:42:44,900
iżda firxa huwa tip ta simili
inventarju jew satchel, ġewwa

923
00:42:44,900 --> 00:42:46,940
ta 'li inti tista' tpoġġi l-affarijiet virtwali.

924
00:42:46,940 --> 00:42:49,852
Huwa jippermettilek li jaħżen aktar
minn biċċa waħda ta 'informazzjoni.

925
00:42:49,852 --> 00:42:51,810
U li jista 'jkun utli
jekk fil-logħba, int

926
00:42:51,810 --> 00:42:53,630
tip ta 'mixi madwar
picking affarijiet up.

927
00:42:53,630 --> 00:42:55,879
U forsi inti tixtieq li żżomm
kollha ta 'dawk il-biċċiet ta' kejk

928
00:42:55,879 --> 00:42:58,260
madwar, u mhux biss jieklu
minnhom wara xulxin.

929
00:42:58,260 --> 00:43:00,010
U allura hemm
jibnu fancier Aħna ser

930
00:43:00,010 --> 00:43:02,932

931
00:43:02,932 --> 00:43:04,640
U jekk aħna qed tmur
aktar mgħaġġel hawn, aħna ser

932
00:43:04,640 --> 00:43:07,345
tara li dawn huma ħafna
Soluzzjoni naturali għall-problemi

Bħala programmi tagħna tibda

tkun xi tkun inti żżomm ikkupjar
u pasta, u t-tqegħid

941

Iżda aktar fuq dawk fil ħafna
f'aktar dettall qabel fit-tul.

943

Għal dawk tal inti aktar komda,

Scratch attwalment jappoġġja affarijiet
bħal ħjut u avvenimenti u aktar.

946

Allura jirrealizzaw li għandha

li qatt ma programmati qabel.

949
00:43:44,460 --> 00:43:47,130
Allura fil-fatt, ejja tagħti ħarsa
fi programm sempliċi jew tnejn.

950
00:43:47,130 --> 00:43:49,920
>> Aħna diġà ħares lejn kif aħna
jista 'jgħid bonjour ma scratch.

951
00:43:49,920 --> 00:43:52,800
Let me imorru quddiem u tiftaħ
ftit program aktar interessanti

Hawn programm fl-dritt
li stajt diġà qabel magħmula.

965
00:44:22,920 --> 00:44:24,880
So let me zoom fl fuq dan.

966
00:44:24,880 --> 00:44:28,780
U jista xi ħadd bl-Ingliż, li jafu
dak li taf, biss minn issa bħala

967
00:44:28,780 --> 00:44:31,650
kif xogħlijiet Scratch, tip ta 'say
fi frażi Ingliża jew sentenza,

00:44:31,650 --> 00:44:35,450
dak ma dan il-programm apparentement jagħmlu?

969
00:44:35,450 --> 00:44:36,836
>> Yeah, fil-shirt oranġjo.

Imma avviż kif nesprimu dak.

975
00:44:47,870 --> 00:44:49,980
Apparentement hemm a
loop hemm, dejjem.

976
00:44:49,980 --> 00:44:53,000
U allura hemm
kundizzjoni, il-jekk espressjoni.

977
00:44:53,000 --> 00:44:55,090
U kollettivament, liema do dawk jfisser?

978
00:44:55,090 --> 00:44:57,210
Dan ifisser dan il-programm
huwa biss dejjem taħdem,

979
00:44:57,210 --> 00:44:59,510
u huwa biss dejjem stennija
u jaraw u jisimgħu

Nibda-programm.

983
00:45:06,475 --> 00:45:08,350
Xejn ma jidher li jkun
jiġri, iżda avviż kif

984
00:45:08,350 --> 00:45:10,152
huwa enfasizzat issa fil-linja isfar.

985
00:45:10,152 --> 00:45:11,360
Li sempliċiment ifisser huwa taħdem.

986
00:45:11,360 --> 00:45:13,770
U għaliex hemm a dejjem
loop, huwa għadu għaddej.

987
00:45:13,770 --> 00:45:19,610
>> So let me jimxu cursor tiegħi fuq Scratch.
[Meow] [meow] U jekk jien jġorrhom off,

988
00:45:19,610 --> 00:45:25,444
[Meow] issa tieqaf, iżda l-programm
għadu għaddej. [Meow] U għalhekk, adorable.

989
00:45:25,444 --> 00:45:28,550
[Meow] Mela ejja jiftħu
ftit aktar avvanzati

>> U issa ejja ara dak
jiġri hawn. [Meow] meowing.

Allura huwa ftit fuq
pilota auto, jekk inti se.

993
00:45:39,297 --> 00:45:39,880
--pet-qattus.

994
00:45:39,880 --> 00:45:42,820
I wonder għaliex.

995
00:45:42,820 --> 00:45:45,389
[Roar] [meow] Hekk kif għamlet dan ix-xogħol?

996
00:45:45,389 --> 00:45:47,930
Well, inti tista tip ta 'raġuni
permezz ta 'dan intuwittivament, forsi.

997
00:45:47,930 --> 00:45:49,346
>> Imma ejja nħarsu lejn il-kodiċi attwali.

998
00:45:49,346 --> 00:45:51,819
Għalhekk għal darb'oħra, meta l-bandiera aħdar
huwa għafast, jagħmlu dan dejjem.

999
00:45:51,819 --> 00:45:53,110
What do inti tixtieq li tagħmel dejjem?

1000
00:45:53,110 --> 00:45:56,150
Ukoll, jekk mouse jmissu
pointer, allura jilagħbu

1001
00:45:56,150 --> 00:46:00,270
ħoss li l-apparentement msejjaħ Lion
5, li l-ġewwa ta 'dan il-proġett, inkella

1002
00:46:00,270 --> 00:46:03,010
play meow ħoss, u
imbagħad stenna żewġ sekondi, sabiex

1004
00:46:04,510 --> 00:46:07,650
Fil-fatt, inti tista 'malajr bidu nett
idejqu yourself u roommates tiegħek.

1005
00:46:07,650 --> 00:46:08,690
>> Ejja tneħħi dan il-blokk.

1006
00:46:08,690 --> 00:46:10,580
U avviż x'hemm sbieħ dwar Scratch.

1007
00:46:10,580 --> 00:46:13,070
Things biss tip ta 'drag
u qatra u jorbtu ma 'xulxin.

1008
00:46:13,070 --> 00:46:14,980
Għalhekk għal darb'oħra, li tikber għal
timla dak li trid.

1009
00:46:14,980 --> 00:46:20,118
Imma jekk jien tneħħi dan, u mbagħad
play hit, [KOMPJUTER blip ĦOSS]

1010
00:46:20,118 --> 00:46:22,904
>> --it tip ta 'waqgħat fuq

1012
00:46:23,820 --> 00:46:27,080
Huwa qal dejjem play dan il-ħoss, iżda
Jien ma jagħtux ċans biex jintemm.

1013
00:46:27,080 --> 00:46:28,205
U hekk li tkun bug.

1014
00:46:28,205 --> 00:46:30,700
U hu għalhekk li kellna
dan ħaġa fil hawn issa.

1015
00:46:30,700 --> 00:46:34,030
Mela ejja attwalment tibda minn scratch--
tip ta 'pun ftit intended--

1016
00:46:34,030 --> 00:46:36,450
li issa għandna the move qattus.

1017
00:46:36,450 --> 00:46:38,130
>> Hekk jien ser tagħmel dan fuq il-fly.

1018
00:46:38,130 --> 00:46:40,910
Jien ser zoom hawn, biss
biex tikseb me beda fuq avvenimenti.

1019
00:46:40,910 --> 00:46:42,000
U l-bandiera aħdar għafast.

1020
00:46:42,000 --> 00:46:43,410
U hemm modi oħra
biex tibda l-iskripts.

1021
00:46:43,410 --> 00:46:44,920
Aħna qed tmur biex jżommha sempliċi hawn.

1022
00:46:44,920 --> 00:46:48,049
>> U issa jien se jmorru
quddiem u jmorru taħt Kontroll.

1023
00:46:48,049 --> 00:46:50,590
U għal darb'oħra, jekk inti tinsa fejn
affarijiet huma, ikklikkja madwar,

1024
00:46:50,590 --> 00:46:52,048
u eventwalment issib jerġgħu.

1025
00:46:52,048 --> 00:46:53,680
So I jridu dejjem tagħmel dak?

1026
00:46:53,680 --> 00:46:58,650
I jridu jużaw il-blokk mozzjoni
li naf jeżisti, jimxu 10 passi.

1027
00:46:58,650 --> 00:47:02,016
>> Mela ejja ara dak li jiġri
hawn jekk I play din il-logħba.

1028
00:47:02,016 --> 00:47:03,390
Thankfully dan ma jmurx wisq.

1029
00:47:03,390 --> 00:47:05,190
I xorta jistgħu tip ta grab lilu
mill-denb u iġbed lura lilu.

1030
00:47:05,190 --> 00:47:07,860
Iżda l-programm għadu għaddej,
hekk hu tip ta 'ġlied lili.

1031
00:47:07,860 --> 00:47:10,870
Iżda huwa d jkun tip ta 'sbieħ jekk I
kondizzjonalment jiffissaw dan fil-kodiċi.

1032
00:47:10,870 --> 00:47:12,800
>> Minħabba li dan huwa not--
fil-fatt dan huwa verament

1033
00:47:12,800 --> 00:47:15,770
mhix logħba gost għal kulħadd ta 'kull età.

1034
00:47:15,770 --> 00:47:18,915
Mela ejja tipprova li jiffissaw dan billi
li xi tip ta 'kundizzjonijiet.

1035
00:47:18,915 --> 00:47:21,670
Hekk jien se jmorru taħt
Kontroll, u mbagħad jekk.

1036
00:47:21,670 --> 00:47:22,660
I simili din l-idea.

1037
00:47:22,660 --> 00:47:27,470
Allura wara li jiċċaqilqu 10 passi,
if-- let me sens fejn I am.

1038
00:47:27,470 --> 00:47:30,799
Jien se jmorru taħt Sensing,
u mbagħad jidher I tista 'tmur hawn.

1039
00:47:30,799 --> 00:47:31,840
ringiela mal-logħbiet forma.

1040
00:47:31,840 --> 00:47:34,380
>> Daqs ma, imma hija
ser jikber biex timla.

1041
00:47:34,380 --> 00:47:35,984
U issa dan huwa menu ftit.

1042
00:47:35,984 --> 00:47:38,650
U issa mouse Pointer I ma
jridu li l-ġurdien, I jridu li l-tarf.

1043
00:47:38,650 --> 00:47:41,700
Allura Scratch huwa intelliġenti biżżejjed li tkun taf
meta Sprite qed imiss it-tarf.

1044
00:47:41,700 --> 00:47:44,360
What do I tixtieq li lilu fil-fatt jagħmlu?

1045
00:47:44,360 --> 00:47:46,025
>> Let me imorru quddiem u l-bidla mozzjoni.

1046
00:47:46,025 --> 00:47:46,940
Inti taf liema?

1047
00:47:46,940 --> 00:47:49,242
Jien ser ikollhom lilu jdur.

1048
00:47:49,242 --> 00:47:51,200
Allura għal 15 gradi mhuwiex
verament se jgħinu lili.

1049
00:47:51,200 --> 00:47:53,990
I tixtieq li lilu jdur
u jmorru l-mod ieħor.

1050
00:47:53,990 --> 00:47:57,740
>> Mela ejja ara dak li jiġri
hawn, jekk I hit Play issa.

1051
00:47:57,740 --> 00:48:01,520
OK, tip ta 'stupid tfittex, iżda
huwa qed jagħmel eżattament dak li għidt.

1052
00:48:01,520 --> 00:48:03,540
U huwa ddawwar il-Sprite kollu.

1053
00:48:03,540 --> 00:48:04,900
Issa jirriżulta nista jiffissaw dan.

1054
00:48:04,900 --> 00:48:06,691
U jien ma nafx kif
li tiffissa din fl-ewwel.

1055
00:48:06,691 --> 00:48:09,190
I tip kellha futz madwar u
tara l-aħjar mod biex isir dan.

1056
00:48:09,190 --> 00:48:12,630
Imma jekk immur to-- ejja ara, mozzjoni.

1057
00:48:12,630 --> 00:48:14,050
Oh, I sabu dan.

1058
00:48:14,050 --> 00:48:15,660
Attwalment, Set Rotazzjoni Style.

1059
00:48:15,660 --> 00:48:18,431
Xellug, lemin, jew ma
dawwar, jew kollha madwar.

1060
00:48:18,431 --> 00:48:19,930
U jirriżulta li huwa dak li nixtieq.

1061
00:48:19,930 --> 00:48:22,920
U jien ser tpoġġi dan mhux tiegħi
loop, minħabba I m'għandhomx bżonn li jiġu stabbiliti

1062
00:48:22,920 --> 00:48:24,487
l-istil rotazzjoni iktar minn darba.

1063
00:48:24,487 --> 00:48:27,570
Jien ser poġġih fuq nett tal
dan il-programm sabiex jiġrilha stabbiliti darba,

1064
00:48:27,570 --> 00:48:28,670
u mbagħad jiftakar.

1065
00:48:28,670 --> 00:48:30,340
U issa jien ser tipprova dan mill-ġdid.

1066
00:48:30,340 --> 00:48:32,520
Let me twaqqaf il-programm.

1067
00:48:32,520 --> 00:48:34,050
>> U issa li fissa li bug.

1068
00:48:34,050 --> 00:48:35,700
Hekk jien iteratively titjib fuq dan.

1069
00:48:35,700 --> 00:48:37,900
Il-programm huwa jkollna
ftit aktar kumplessi u akbar,

1070
00:48:37,900 --> 00:48:40,810
imma jien tieħu tarbija passi biex ngħidu hekk,
u gdim żgħar barra mill-problema

1071
00:48:40,810 --> 00:48:42,010
biex tiksbu aħjar u aħjar.

1072
00:48:42,010 --> 00:48:43,260
Iżda dan ukoll, huwa tip ta 'lame.

1073
00:48:43,260 --> 00:48:43,900
>> Inti taf liema?

1074
00:48:43,900 --> 00:48:49,860
Titlob xi ħadd bil-verament tajba,
vuċi terribbli simili li toħroġ?

1075
00:48:49,860 --> 00:48:51,210

falza, iżda ma jkollu 0 u 1.

>> So I tista approssimati l-istess idea.

ippressat, mbagħad issettja varjabbli għal 0.

jekk siekta, il-varjabbli, huwa ta '0,

mbagħad stabbiliti siekta għal 1,
inkella sett siekta għal 0.

1180
00:52:41,035 --> 00:52:43,035
Allura huwa ħa ftit blokki
biex jesprimu li, iżda kollha

1181
00:52:43,035 --> 00:52:47,280
Li qed nagħmel huwa toggling l-istat ta '
dan il-varjabbli għal 0 jew 1, jew 0 jew 1

hekk jekk siekta hija falza.

1185
00:52:53,400 --> 00:52:57,910

Iżda tinnota li għandha żewġ sprites.

1199
00:53:34,130 --> 00:53:37,520
Allura mhux biss żewġ skripts bl
Sprite wieħed, iżda żewġ sprites.

1200
00:53:37,520 --> 00:53:40,750
U jekk I ikklikkja fuq il-Guy blu bħala I
diġà għandhom, nara hu bħala programm wieħed

1201
00:53:40,750 --> 00:53:43,790
up here li litteralment biss jgħid
dan, meta nirċievi avveniment,

1202
00:53:43,790 --> 00:53:45,620
jgħidu "Polo" għal żewġ sekondi.

00:53:48,460 --> 00:53:52,500
jekk l-iskrittura Guy oranġjo huwa
kwalunkwe indikazzjoni, apparentement

1205
00:53:52,500 --> 00:53:57,380
kull darba I hit l-ispazju bar,
x'inhu l-Guy oranġjo se jagħmlu?

1206
00:53:57,380 --> 00:53:58,642
Hu għaddej biex jgħidu "Marco."

1207
00:53:58,642 --> 00:53:59,850
U allura dan huwa blokk ġdid.

1208
00:53:59,850 --> 00:54:02,409
Imxejna ma bbenefikawx dan qabel,
iżda xxandar avveniment.

1209
00:54:02,409 --> 00:54:04,200
UI tista 'sejħa hija
avveniment xejn li rridu.

1210
00:54:04,200 --> 00:54:06,033
>> Aħna ser terga 'lura għal dan
forsi qabel fit-tul.

1211
00:54:06,033 --> 00:54:08,410
Iżda xandir avveniment
huwa mod għall Sprite wieħed

1212
00:54:08,410 --> 00:54:11,836
biex jitkellem ieħor billi
essenzjalment jgħaddiha messaġġ.

1213
00:54:11,836 --> 00:54:12,960
Mhuwiex messaġġ tara.

1214
00:54:12,960 --> 00:54:14,130
Mhuwiex xi ħaġa viżwali.

1215
00:54:14,130 --> 00:54:17,370
Huwa tip ta 'messaġġ kompjuter
li l-Guy-oħra huwa smigħ għall.

1216
00:54:17,370 --> 00:54:21,210
Minħabba fil-fatt, il-Guy blu, irtirar
ma jkollux meta bandiera aħdar għafast.

1217
00:54:21,210 --> 00:54:23,290
>> Huwa minflok għandu, meta nirċievi avveniment.

1218
00:54:23,290 --> 00:54:26,850
Meta hu gets mogħtija din in-nota fil-klassi,
biex ngħidu hekk, huwa għandu jgħidu "Polo."

1219
00:54:26,850 --> 00:54:30,200
U għalhekk l-effett nett huwa li meta I
laqat il-bandiera aħdar, xejn jiġri.

1220
00:54:30,200 --> 00:54:34,940
Imma meta I hit l-ispazju bar, huwa jgħid
"Marco," huwa jirrispondi "Polo."

1221
00:54:34,940 --> 00:54:38,350
Imma l-unika Sprite jien
interazzjoni ma huwa l-waħda oranġjo.

1222
00:54:38,350 --> 00:54:40,980
Allura dan huwa mod ta 'tip ta'
tgħaddi messaġġi bejn sprites

1223
00:54:40,980 --> 00:54:43,210
u li minnhom jikkomunikaw

1224
00:54:43,210 --> 00:54:46,280
>> Issa ejja nħarsu lejn wieħed aħħar
wieħed hawn imsejħa Threads.

1225
00:54:46,280 --> 00:54:49,370
U Avviż dan bil-logħob dan.

1226
00:54:49,370 --> 00:54:51,184
Allura dawn huma żewġ sprites.

1227
00:54:51,184 --> 00:54:52,600
L-għasafar huwa tip ta 'jtajru madwar.

1228
00:54:52,600 --> 00:54:53,310
Hu bouncing.

1229
00:54:53,310 --> 00:54:55,890
M'hemm l-ebda "Ouch," iżda istess idea.

1230
00:54:55,890 --> 00:54:58,230
>> Iżda l-qattus jidher pretty intelliġenti.

1231
00:54:58,230 --> 00:55:01,010
X'inhu l-qattus apparentement tagħmel?

1232
00:55:01,010 --> 00:55:03,430
U stenna għal dan.

1233
00:55:03,430 --> 00:55:05,010
X'inhu l-qattus apparentement tagħmel?

1234
00:55:05,010 --> 00:55:07,740
Huwa mhux biss bouncing.

1235
00:55:07,740 --> 00:55:09,860
>> Hu wara l-għasafar.

1236
00:55:09,860 --> 00:55:13,920
U hekk apparentement, hemm mod
bil-kombinazzjoni ta 'blokki here--

1237
00:55:13,920 --> 00:55:15,760
u ejja nħarsu lejn il-qattus reali fast.

1238
00:55:15,760 --> 00:55:20,270
Forever, jekk jmissu għasafar, allura jilagħbu
il-ħoss Lion 4, tkun xi tkun li hu.

1239
00:55:20,270 --> 00:55:21,360
We jinstemgħu darba.

1240
00:55:21,360 --> 00:55:25,431
Inkella, punt lejn
għasafar, u jimxu pass wieħed.

1241
00:55:25,431 --> 00:55:27,680
Issa l-fatt li huwa wieħed
pass huwa dak li jagħti l-għasafar

1242
00:55:27,680 --> 00:55:29,850
daqsxejn ta 'vantaġġ
inizjalment, imma jekk irridu minflok

1243
00:55:29,850 --> 00:55:32,980
jagħmlu dan 10, per eżempju, sabiex
li kull iterazzjoni ta loop hu

1244
00:55:32,980 --> 00:55:34,100
jiċċaqalqu 10 passi ta 'żmien.

1245
00:55:34,100 --> 00:55:35,280
Allura aktar spazju.

1246
00:55:35,280 --> 00:55:36,650
Ejja naraw x'jiġri imbagħad.

1247
00:55:36,650 --> 00:55:38,740
[LION roar] Mhux dak kollu li ħafna aħjar.

1248
00:55:38,740 --> 00:55:41,460
Allura issa ejja jippruvaw itejbu
fuq dawn ftit iteratively,

1249
00:55:41,460 --> 00:55:43,330
u terga 'lura għal dik
kunċett ta 'funzjoni.

1250
00:55:43,330 --> 00:55:46,580
>> U fil-fatt wieħed mill-fundamentali
takeaways tad-disinn klassi.

1251
00:55:46,580 --> 00:55:49,560
Mhux biss bil-miktub programmi li jaħdmu
u li huma korretti, iżda huma ukoll

1252
00:55:49,560 --> 00:55:50,080
maħsuba.

1253
00:55:50,080 --> 00:55:54,349
U d-disinn huwa ħafna aktar suġġettivi,
u int ser tingħata aħjar fuq dan matul iż-żmien.

1254
00:55:54,349 --> 00:55:57,390
Imma ejja tagħti xi passi tarbija lejn
tibda bi programm li taħdem,

1255
00:55:57,390 --> 00:55:59,310
assolutament, iżda mhux tajjeb ħafna.

1256
00:55:59,310 --> 00:56:00,650
Mhuwiex tajjeb ħafna bil-miktub.

1257
00:56:00,650 --> 00:56:03,830
>> Allura hawnhekk programm li ma dan.

1258
00:56:03,830 --> 00:56:08,060
Sogħla, sogħla, sogħla.

1259
00:56:08,060 --> 00:56:09,880
X'tagħmel il-programm look like?

1260
00:56:09,880 --> 00:56:11,330
Jistenna korretta lili.

1261
00:56:11,330 --> 00:56:13,370
Huwa qal couch għal
tieni, allura tistenna.

1262
00:56:13,370 --> 00:56:14,515
>> Imbagħad jgħid li għal darb'oħra, allura tistenna.

1263
00:56:14,515 --> 00:56:16,056
Imbagħad jgħid li għal darb'oħra, allura tistenna.

1264
00:56:16,056 --> 00:56:18,770
U allura l-programm impliċitament
truf, għaliex hemm l-ebda linja.

1265
00:56:18,770 --> 00:56:21,325
Iżda għaliex dan huwa programm ħażin bil-miktub?

1266
00:56:21,325 --> 00:56:22,950
Anke jekk inti stajt qatt programmati qabel?

1267
00:56:22,950 --> 00:56:25,240
Bħal, liema rubs l
mod żbaljat, forsi hawn?

1268
00:56:25,240 --> 00:56:26,016
Yeah?

1269
00:56:26,016 --> 00:56:29,278
>> UDJENZA: [inaudible]

1270
00:56:29,278 --> 00:56:29,950

1271
00:56:29,950 --> 00:56:30,950
DAVID J. Malan: Eżattament.

1272
00:56:30,950 --> 00:56:32,700
Int tirrepeti
yourself darb'oħra u għal darb'oħra.

1273
00:56:32,700 --> 00:56:36,190
U litteralment, I kkupjati u pasted
tnejn minn dawk il-blokki u għal darb'oħra.

1274
00:56:36,190 --> 00:56:39,237
U dan huwa eżattament it-tip ta 'sanità
iċċekkja li inti għandek tkun tagħmel.

1275
00:56:39,237 --> 00:56:39,820
Stenna minuta.

1276
00:56:39,820 --> 00:56:41,070
Jekk I really tkun qiegħda tagħmel dan?

1277
00:56:41,070 --> 00:56:43,610
Allura x'hemm dan x'inhu l-
soluzzjoni ovvja forsi?

1278
00:56:43,610 --> 00:56:44,680
Għandhom xi tip ta loop.

1279
00:56:44,680 --> 00:56:46,860
U jien irtirar ma pjuttost
dak l-biċċa puzzle huwa,

1280
00:56:46,860 --> 00:56:48,810
imma jekk jien tħares lejn il-
iterazzjoni li jmiss hawn,

1281
00:56:48,810 --> 00:56:50,560
fil-fatt, ma hemm
biss il-loop dejjem,

1282
00:56:50,560 --> 00:56:52,560
hemm jirrepetu xi numru ta 'drabi.

1283
00:56:52,560 --> 00:56:54,080
U hekk stajt speċifikat tlieta.

1284
00:56:54,080 --> 00:56:57,839
U issa avviż kif aktar ħarxa, kif
ħafna aktar konċiż dan il-programm hu.

1285
00:56:57,839 --> 00:56:59,630
U f'ċertu sens, kemm
ħafna aktar maintainable.

1286
00:56:59,630 --> 00:57:02,840
Jekk I tixtieq li tibdel il-kelma
minn sogħla għal xi ħaġa oħra,

1287
00:57:02,840 --> 00:57:07,530
bħall achoo, bħal hu għatis.

1288
00:57:07,530 --> 00:57:09,770
Imbagħad I bidla f'wieħed
post, u mhux tlieta.

1289
00:57:09,770 --> 00:57:12,050
Allura dan diġà jħoss simili
disinn ftit aħjar.

1290
00:57:12,050 --> 00:57:14,610
Let me sogħla minflok miftuħa

1291
00:57:14,610 --> 00:57:17,670

I tibda għadd ta '0, tipikament.

1292
00:57:17,670 --> 00:57:20,950
Issa dan jistenna scarier ftit fil
ewwel, iżda l-effett huwa l-istess.

1293
00:57:20,950 --> 00:57:22,590
Sogħla, sogħla, sogħla.

1294
00:57:22,590 --> 00:57:26,920
Imma dak li jidher li jkun fundamentalment
ġdid fil-parti ta 'fuq tal-programm?

1295
00:57:26,920 --> 00:57:28,670
Stajt jitneħħew l say.

1296
00:57:28,670 --> 00:57:29,830

Blokk sogħla.

1300
00:57:33,670 --> 00:57:35,410
I mean, franchement, I jidhru tip
ta idjota jekk I ma biss

1301
00:57:35,410 --> 00:57:37,285
tibda bil-blokka
li l-apparentement sejjaħ

1302
00:57:37,285 --> 00:57:38,894
"sogħla," jekk dan huwa kollu nixtieq lilu do.

1303
00:57:38,894 --> 00:57:40,310
Iżda dan ma jeżistix fil Scratch.

1304
00:57:40,310 --> 00:57:43,396
Pjuttost I marru lil wieħed fil-
paletta imsejħa Aktar Blokki hawn,

1305
00:57:43,396 --> 00:57:46,270
u I drag dan ħaġa vjola big
hawnhekk li tikri me jiddefinixxu funzjoni.

1306
00:57:46,270 --> 00:57:48,240
Hija essenzjalment tikri me
joħolqu puzzle tiegħi stess

1307
00:57:48,240 --> 00:57:51,280

tixtieq, li tista 'tagħmel xejn nixtieq,

00:57:51,280 --> 00:57:52,360
iżda tagħti dan l-isem.

1309
00:57:52,360 --> 00:57:57,050
Hija tagħti me a ġdid, biċċa puzzle vjola
li issa ma kwalunkwe I għid li tagħmel.

1310
00:57:57,050 --> 00:58:01,060
Allura din il-biċċa vjola hawn
jikkorrispondi għal dan wieħed hawn.

1311
00:58:01,060 --> 00:58:01,960
>> U dak ma tagħmel?

1312
00:58:01,960 --> 00:58:03,930
Hija tgħid sogħla għal

1313
00:58:03,930 --> 00:58:07,330
U issa stajt tip ta 'ħoloq

sabiex iġib ruħu

1316
