Java slow down for loop without slowing down rest of program

Question

I'm creating a video game and I've got a for loop that recovers your health

public void recoverHealth() {
    if (curHealth < finalHealth) {
        for (double i = 0; i < finalHealth; i = i + 0.1) {
            curHealth = curHealth + 0.1;
            System.out.println("health: " + curHealth);
        }
    }
}

But the problem is that java goes through this so fast it goes from 0-20 before the game even starts. How can I possibly slow down the recoverHealth() method without slowing down the entire game such as Thread.sleep doesn't work..

try {
    Thread.sleep(1000);
} catch (Exception e) {
    e.printStackTrace();
}

Any ideas?

Answer 1

将recoverHealth放入一个单独的线程中，并按照您的描述使用Thread.sleep() 。

Answer 2

Add this to your game program, where curHealth is accessible.

timer = new Timer();
timer.schedule(new TimerTask (){
    public void run() {
        curHealth = curHealth + 0.1;
    }
}, 1000);
