Adding a delay without Thread.sleep and a while loop doing nothing

Question

I need to add delay without using Thread.sleep() or a while loop doing nothing. The game im editing(Minecraft) clock runs on \"Ticks\" but they can fluctuate depending on yo

Answer 1

Something like the following should give you the delay you need without holding up the game thread:

private final long PERIOD = 1000L; // Adjust to suit timing
private long lastTime = System.currentTimeMillis() - PERIOD;

public void onTick() {//Called every "Tick"
    long thisTime = System.currentTimeMillis();

    if ((thisTime - lastTime) >= PERIOD) {
        lastTime = thisTime;

        if(variable) { //If my variable is true
            boolean = true; //Setting my boolean to true
            /**
            *Doing a bunch of things.
            **/
            //I need a delay for about one second here.
            boolean = false; //Setting my boolean to false;
        }
    }
}
