Week06 昱霖的筆記

播放音樂

import ddf.minim.*;

Minim minim;
AudioPlayer player;
void setup(){
  minim = new Minim(this);
  player=minim.loadFile("Kalimba.mp3");
  player.play();
}

可跳出一顆球

float fruitX, fruitY, fruitVX, fruitVY;

void setup(){

  size(900,700);

  fruitX=30; fruitVX=3;

  fruitY=700; fruitVY=-35;

}

void draw(){

  background(0);

  ellipse(fruitX,fruitY, 100,100);

  fruitX+=fruitVX;

  fruitY+=fruitVY;

  fruitVY+=0.98;

}

跑出多顆球

float [] fruitX=new float[20];

float [] fruitY=new float[20];

float [] fruitVX=new float[20];

float [] fruitVY=new float[20];

void setup(){

  size(800,600);

  for(int i=0;i<20;i++){

  fruitX[i]=random(800); fruitVX[i]=3;

  fruitY[i]=700; fruitVY[i]=-35;

  }

}

void draw(){

  background(0);

  for(int i=0;i<20;i++){

  ellipse(fruitX[i],fruitY[i], 100,100);

  fruitX[i]+=fruitVX[i];

  fruitY[i]+=fruitVY[i];

  fruitVY[i]+=0.98;

}

}

使球不規則跳動，並重複出現

float [] fruitX=new float[20];

float [] fruitY=new float[20];

float [] fruitVX=new float[20];

float [] fruitVY=new float[20];

void reborn(int i){

  fruitX[i]=random(800); fruitVX[i]=random(6)-3;

  fruitY[i]=700; fruitVY[i]=-35;

}

void setup(){

  size(800,600);

  for(int i=0;i<20;i++){

    reborn(i);

  }

}

void draw(){

  background(0);

  for(int i=0;i<20;i++){

    if( dist(mouseX,mouseY,fruitX[i],fruitY[i])<=50 ){

      reborn(i);continue;

    }

  ellipse(fruitX[i],fruitY[i], 100,100);

  fruitX[i]+=fruitVX[i];

  fruitY[i]+=fruitVY[i];

  fruitVY[i]+=0.98;

  if(fruitY[i]>700) reborn(i);

}

}

將圈圈改成蘋果

加入PImage

//float fruitX, fruitY, fruitVX, fruitVY;

PImage img;

float [] fruitX=new float[20];

float [] fruitY=new float[20];

float [] fruitVX=new float[20];

float [] fruitVY=new float[20];

void reborn(int i){

  fruitX[i]=random(800); fruitVX[i]=random(6)-3;

  fruitY[i]=700; fruitVY[i]=-35;

}

void setup(){

  size(800,600);

  img = loadImage("Apple.png");

  for(int i=0;i<20;i++){

    reborn(i);

  }

}

void draw(){

  background(0);

  for(int i=0;i<20;i++){

    if( dist(mouseX,mouseY,fruitX[i],fruitY[i])<=50 ){

      reborn(i);continue;

    }

   

  image(img,fruitX[i],fruitY[i], 100,100);

  fruitX[i]+=fruitVX[i];

  fruitY[i]+=fruitVY[i];

  fruitVY[i]+=0.98;

  if(fruitY[i]>700) reborn(i);

}

}
