如何使用此代码限制Java游戏的CPU使用率?我认为一种方法可能是使用Thread.sleep()
,但前提是我可以计算时间或类似的东西。有人可以帮助我吗?
public void run(){
this.requestFocus();
long lastTime = System.nanoTime();
double amountOfTicks = 60.0;
double ns = 1000000000 / amountOfTicks;
double delta = 0;
long timer = System.currentTimeMillis();
int frames = 0;
while(isRunning){
long now = System.nanoTime();
delta += (now - lastTime) / ns;
lastTime = now;
while(delta >= 1){
tick();
delta--;
}
render();
frames++;
if(System.currentTimeMillis() - timer > 1000){
timer += 1000;
frames = 0;
}
}
stop();
}
答案 0 :(得分:0)
除缺失的部分外,这看起来非常简单。考虑您想要以固定的速率更新。
while(isRunning){
tick();
render();
long now = System.nanoTime();
double delta = now - lastTime;
double remaining = delta - ns;
if(remaining>1000){
try{
Thread.sleep((int)(remaining/1000));
} catch(InterruptedException e){
throw new RuntimeException(e);
}
}
frames++;
lastTime = System.nanoTime();
if(System.currentTimeMillis() - timer > 1000){
timer += 1000;
frames = 0;
}
}
