How to use the sleep and thread?

[jiuhu]

I'm coding a program to move a player on the screen,
but the program directly run to the end,
the animation part dose not display,
how can i modify my code to show the movement of the player?

here is the run function,

Thread t, w;
 
public void run() {
    while (isClick) {
        try {
            repaint();
            t.sleep(500);
            int j = playerStep + 40; 
            while(playerStep < j) {
                try {
                    playerStep += 10;
                    repaint();
                    w.sleep(300);
                } catch (InterruptedException err) {
                    JOptionPane.showMessageDialog(null, "Moving error!");
                }
            }
        } catch (InterruptedException err) {
            JOptionPane.showMessageDialog(null, "Drawing error!");
        }
        isClick = false;
        repaint();
    }
}

Thanks a lot.

You set isClick to false at the end of your loop. That makes your loop to run only once. This is why you see no movement!

sorry that, i did not mention, i use a button click to control the movement.
whichmeans, whenever i click on the button, it will move.

by the way, this code can run, but it directly show me the final screen, which is i can not see the progress of the movement.

thanks

If so just remove the sleep statements and your loop and do only the following:

playerStep += 10;
repaint();

But if the button is only starting the movement (which means you will not need to press the button on each movement), then you still should not have "isClick = false;" there. You can place it inside an if statement in that case:

if (playerStep == 100) isClick = false;
