Thread only running correctly if there is a System.out.println() inside the while true loop

Question

Basicly, I\'m making a game which to update the players position, it uses this thread:

@Override
public void run() {
    while(true) {
        System.out.pri         


        

Answer 1

Don't know if that would solve it, but it looks like you're giving the JVM a hard time... Try adding a short sleep (which is the correct way to implement a game thread) before each updatePos(x, y) call.

@Override
public void run() {
    while(true) {
    Try
    {
        Thread.sleep(50);
    }
    catch (Exception e){}

    updatePos(x, y);
    }

}}
