🔺程式

float fruitX, fruitY, fruitVX, fruitVY;

void setup(){

  size(800,600);

  fruitX=30; fruitY=700;

  fruitVX=3; fruitVY=-35;

}

void draw(){

  background(0);

  ellipse(fruitX, fruitY, 100,100);

  fruitX+=fruitVX;

  fruitY+=fruitVY;

  fruitVY+=0.98;

}

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); fruitY[i]=700;

  fruitVX[i]=3; fruitVY[i]=-35;

  }

⇒random

For example, random(5) returns values between 0 and 5 (starting at zero, and up to, but not including, 5).

}

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;

  }

}

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); fruitY[i]=700;

  fruitVX[i]=random(6)-3; 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;

    }

⇒continue

When run inside of a for or while, it skips the remainder of the block and starts the next iteration. 

    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);

  }
