1.製作血條

利用布林變數控制遊戲是否結束

int life=10;
boolean gg=false;
void setup(){
  size(500,500);
}

void draw(){
  background(0,0,205);
  fill(255); rect(50,50,100,20);
  fill(255,0,0); rect(50,50,life*10,20);
  if(gg){
    textSize(40);
    text("Game Over",150,150);
  }
}

void mousePressed(){
  life--;
  if(life<=0) gg=true;
}

2.開場畫面切換






int state=0;
int remaintime=0;
void setup(){
  size(800,600);
}
void draw(){
  if (state==0){
    op();
    if(key=='1')  {state=1; remaintime=5*60;}
  }
  else if(state==1){
    play();
  }
  else if(state==2){
    ed();
  }
}
void op(){
  background(0);
  fill(#F5DE07);
  textSize(30); text("Press 1 to play",10,100);
}
void play(){
  background(#F0D90C);
  fill(#161FF2);  text("Press 2 to end",10,100);
  text("remain: "+remaintime,10,150);
  remaintime--;
  if(remaintime<=0) state=2;
}
void ed(){
  background(0);
  fill(#F0D90C);  text("Game Over",10,100);
}

將(remaintime+59)/60 可以換成一般秒數
沒+59的話會和實際秒數延遲一秒
