Kev ua haujlwm tuaj yeem thauj ntau cov ntaub ntawv sab nraud, ntawm uas muaj peb hom uas nquag siv. Lawv yog cov duab, suab thiab yees duab sib cais.

Hauv tshooj lus no, peb yuav tham txog yuav ua li cas thauj lub suab thiab yees duab kom ntxaws, ua ke nrog cov xwm txheej. Thaum kawg, koj tuaj yeem tsim koj tus kheej cov keyboard lossis suab paj nruag.

Kauj Ruam 1: Nyeem Duab

Ua ntej peb pib, cia saib rov qab rau txoj hauv kev ntawm kev thau duab.

Kauj Ruam 2: Duab ntsig txog kev ua haujlwm

Ua ntej peb siv cov haujlwm no, peb yuav tsum tsim cov khoom siv duab los ntawm PImage. Tom qab ntawd peb tuaj yeem siv cov haujlwm no txhawm rau txheeb xyuas txhua yam khoom duab.

Tsis txhob hnov qab khaws koj cov duab los rau hauv cov ntaub ntawv ua ntej ua haujlwm koj li program.

Kauj Ruam 3: Tso Music, Ua Si & Nres

Hauv cov hauv qab no, peb pib ua ntu zus qhia kev hu nkauj rau koj. Zoo heev rau kev thau duab, koj yuav tsum tshaj tawm lub suab khoom thaum pib. Koj tuaj yeem xa mus rau qhov piv txwv hauv qab no los ntawm cov qauv sau ntawv tiag.

Txoj Cai Piv Txwv (10-1):

[cceN_cpp ntsiab lus = "kaj ntug"] ntshuam ua tiav.sound.*;

SoundFile suab;

void teeb tsa () {

loj (640, 360);

keeb kwm yav dhau (255);

suab = SoundFile tshiab (qhov no, "1.mp3");

}

void kos () {

}

void keyPressed () {

// Ua suab

yog (qhov tseem ceeb == 'p') {

suab.play ();

}

Nres suab

yog (qhov tseem ceeb == 's') {

suab.stop ();

}

} [/cceN_cpp]

Kev npaj:

Ua nws tus kheej tsis nqa lub tsev qiv ntawv suab. Koj yuav tsum rub nws los ntawm koj tus kheej. Yog li, ua ntej sau koj cov cai, koj yuav zoo dua los npaj cov hauv qab no.

Ntxiv tsev qiv ntawv rau Kev Ua. Nov yog kev coj ua ib txwm muaj. Xaiv los ntawm cov ntawv qhia zaub mov bar rau "Tool"- "Add Tool", thiab tom qab ntawd hloov mus rau "Libraries". Sau cov lus tseem ceeb ntawm lub tsev qiv ntawv rau hauv kab tshawb nrhiav kom koj tuaj yeem rub tawm thiab teeb tsa ncaj qha.

Txawm li cas los xij, yog tias peb siv txoj haujlwm no hauv peb lub tebchaws (hauv Suav Teb), peb tsis tuaj yeem rub nws los ntawm kev txuas lub vev xaib ncaj qha. Peb yuav tsum pib VPN. Txawm hais tias peb pib nws, yuav muaj xwm txheej tsis xwm yeem. Yog li koj yuav tsum ua siab ntev sim nws ob peb zaug. Nov yog txoj hauv kev yooj yim tshaj plaws ntawm kev thauj khoom. Yog tias koj tsis tuaj yeem teeb tsa, koj yuav tsum rub tawm los ntawm lub vev xaib raug cai los ntawm phau ntawv. (https://processing.org/reference/libraries/) Vim tias phau ntawv teeb tsa txheej txheem yog qhov nyuaj heev, peb yuav tham ntxiv hauv lwm tshooj.

Txoj Cai Exaplain:

Lub tsev qiv ntawv suab tuaj yeem ua haujlwm tau zoo tom qab kev npaj ua tiav. Cope cov cai saum toj no, nyem RUN, tom qab ntawd nws yuav ua haujlwm. Nias tus yuam sij "P" los ua suab paj nruag, "S" kom nres suab paj nruag.

Yog tias nws tau siv rau txoj haujlwm, peb yuav tsum thauj nws ua ntej. Thaum pib, peb yuav tsum ntxiv kab lus "ntshuam ua cov suab.*". "ntshuam" yog lo lus tseem ceeb, lub ntsiab lus thauj khoom. Ntxiv lub tsev qiv ntawv lub npe tom qab "ntshuam", tom qab ntawd nws yuav thauj lub tsev qiv ntawv. Tus Tsov tus tw feem ntau ua raws lub cim ntawm "*", yog li nws yuav thauj tag nrho cov tsev qiv ntawv cuam tshuam nrog chav kawm rau hauv qhov haujlwm yam tsis tas yuav ntxiv lawv ib leeg los ntawm ib tus.

Hauv kab lus thib ob, "SoundFile suab;" tau tshaj tawm cov khoom siv suab. SoundFile zoo ib yam li PImage.

Hauv kev teeb tsa kev ua haujlwm, "suab = SoundFile tshiab (qhov no," 1.mp3 ");" yog siv los tsim cov khoom thiab txhais nws txoj kev nyeem. Ntawm no peb yeej tau pib siv lub tswv yim tshiab Class. Tam sim no peb tsis tham txog nws tob. Peb tsuas yog xav paub nws yog txoj hauv kev sau thiab qhov ntsuas kawg yog txhawm rau sau qhov chaw nyob ntawm cov nkauj.

Ntawm cov keyPressed () cov xwm txheej, "sound.play ()" thiab "sound.stop ()" kuj ua haujlwm raws li kev ua si thiab nres. "." nyob hauv nruab nrab qhia txog tus tswv cuab ua haujlwm uas ua si thiab tso tseg rau cov khoom suab. Peb tuaj yeem suav cov tswv cuab ua haujlwm raws li cov haujlwm muaj nyob hauv cov khoom. Nws yog tus tswv ntawm qhov khoom no, uas tau hais ua ntej. Tom qab ntawd, thaum peb xav tau los ua ntau yam khoom siv suab, peb tsuas yog ntxiv ".play ()" tom qab lub npe sib txawv txheeb ze.

Cov peev txheej suab yuav tsum khaws cia rau hauv cov ntaub ntawv cov ntaub ntawv hauv tib daim ntawv teev npe ntawm sketchfile (nrog pde txuas ntxiv). Yog tias tsis muaj, koj tuaj yeem tsim ib qho.

Tsis txhob hnov qab sau qhov kos duab. Txawm hais tias koj tsis tau kos cov duab, nws yog qhov tsim nyog los ua suab paj nruag kom tiav.

Cov txheej txheem saum toj no zoo li nyuaj heev, tab sis koj yuav tsum ntxiv ob peb kab lus ntawm cov cai nkaus xwb, tom qab ntawd koj tuaj yeem paub ua haujlwm. Nws yooj yim heev.

Kev ua haujlwm txhawb nqa cov suab sib xws xws li mp3, wav, ogg, thiab lwm yam.

Kauj Ruam 4: Tswj Lub Suab Nkauj

Cov piv txwv hauv qab no yuav pib dhau los ua qhov nthuav. Kev ua haujlwm tau muab qee qhov haujlwm uas tuaj yeem tswj suab paj nruag ua si nrawm. Nyob rau tib lub sijhawm, lub suab nrov yuav hloov nrog suab paj nruag ua si nrawm. Thaum peb siv nas los tswj, nws yuav tsim cov txiaj ntsig zoo heev.

Ntawm no peb tau siv ob qhov sib txawv pmouseX thiab pmouseY nqa hauv Kev Ua Haujlwm nws tus kheej. Lawv zoo ib yam li mouseX thiab mouseY tab sis qhov lawv tau txais yog kev sib koom ntawm nas hauv tus ncej tas los.

Hauv Kev kos duab, peb tau siv kab kab () los hloov qhov kev ua haujlwm qub ellipse (). Qhov no ua rau kev sib koom ua ke ntawm cov thav duab kawg txuas nrog kev ua haujlwm ntawm cov thav duab tam sim no ncaj qha. Yog li peb tuaj yeem kos kab ncaj ncaj los yog nkhaus.

Hauv qhov kev tshwm sim mouseDragged, peb tau tsim qhov xwm txheej tshiab tshwm sim. Los ntawm kev txiav txim siab seb qhov kev sib koom tes ntawm lub thav duab kawg thiab lub thav duab tam sim no nyob rau hauv ib sab kom paub seb puas muaj kev sib koom tes hla. Siv qhov xwm txheej no ua piv txwv: "yog ((mouseX - 100) * (pmouseX - 100) <0)". Ntawm nws, los ntawm qhov txiaj ntsig zoo thiab tsis zoo tshwm sim los ntawm "mouseX - 100", peb tuaj yeem paub tias mouseX nyob ntawm sab xis lossis sab laug ntawm kab rov tav coodinate 100. Zoo ib yam li "pmouseX - 100". Yog li ntawd, thaum ob lub ntsiab lus nyob rau sab xub ntiag thiab sab nraub qaum tsis nyob hauv ib sab, qhov zoo sib npaug tsis zoo, nws yuav tau txais tus lej tshiab tsis zoo. Yog li qhov ua tiav kev mob siab.

Qhov saum toj no yog cov lus piav qhia yooj yim, uas tau siv qee qhov kev ua lej zauv-Ob qhov tsis zoo sib npaug yuav tsim qhov zoo. Koj tseem tuaj yeem faib nws ua ob qhov xwm txheej los sib tham sib cais. Txawm li cas los xij, nws nyuaj dua los sau cov lus txiav txim. Cov kev txiav txim siab "yog ((mouseX = 100) || (mouseX> 100 && pmouseX <= 100))" yog sib npaug rau kev txiav txim siab ntawm cov cai.
