week07-卓佾柔的上課筆記

一、皮卡丘打排球

void setup(){

  size(800,600);

}

float ballX=200,ballY=200,ballVX=0,ballVY=3;

float pika1X=200,pika1Y=420,pika1VX=0,pika1VY=0;

float pika2X=600,pika2Y=420,pika2VX=0,pika2VY=0;

boolean bGameOver=false;

void draw(){

  background(#2085D6);

  noStroke(); fill(#FAC105); rect(0,500,800,100);

  fill(255,0,0); ellipse(ballX,ballY,60,60);

  rect(400,340,10,260);

 

  fill(#F5FA05); ellipse(pika1X,pika1Y,60,100);  //皮卡丘起始位置

  fill(#F5FA05); ellipse(pika2X,pika2Y,60,100);

 

  if(bGameOver) return;   //如果球掉落遊戲結束(皮卡丘跟球不能再移動)

 

  ballX += ballVX; ballY += ballVY;

  ballVY += 0.98;  //重力加速度

  pika1X+=pika1VX; pika1Y += pika1VY; pika1VY+=0.98;

  if(ballY>=500-30) bGameOver=true; //球落地,GAMEOVER

  if(pika1Y>=500-50) {pika1VY=0; pika1Y=500-50;}

  if(dist(pika1X,pika1Y,ballX,ballY)<=80) ballVY=-ballVY;

}

void keyPressed(){

  if(key=='a') pika1VX=-3;

  if(key=='s') pika1VY=0;

  if(key=='d') pika1VX=3;

  if(key=='w') pika1VY=-20;

}

void keyReleased(){  //放開鍵盤的速度為0

  if(key=='a') pika1VX=0;

  if(key=='s') pika1VY=0;

  if(key=='d') pika1VX=0;

  if(key=='w') pika1VY=0;

}
