Delaying Animation

[javaa]

Hi! I was just wondering how to update an animation every second instead of almost instantly. Thanks!

You could slow down the animation loop. How you do this will depend almost completely on how you are currently animating.

heres what I have so far but the delay method isnt really working

import java.awt.*;
import java.applet.Applet;

public class Liang extends Applet {
	public void paint( Graphics screen ) {
		setBackground( Color.green );
		Image hare = getImage( getDocumentBase(), "hare.gif" );
		Image tortoise = getImage( getDocumentBase(), "tortoise.gif" );
		screen.drawImage( hare, 5, 5, this);
		screen.drawImage(tortoise, 5, 120, this); 
		screen.drawLine( 0, 115, 1300, 115);
		
		int disfromfinh = 50;
		int disfromfint = 50;

		int xh = 5;

		int xt = 5;

		while ( disfromfinh > 0 & disfromfint > 0 ) {
			// For the hare

			int moveh = (int)(Math.random() * 10) + 1;
			if (moveh == 1 | moveh == 2) {
				delay();delay();delay();
				screen.clearRect(xh, 5, xh + 118, 107);
				int a1 = xh + 180;
				screen.drawImage( hare, a1 , 5, this);
				xh = a1;

				disfromfinh -= 9;
			}
			else if (moveh == 3 | moveh == 4 | moveh == 5) {
				delay();delay();delay();

			}
			else
				screen.clearRect(xh, 5, xh + 118, 107);

				disfromfinh = disfromfinh;

			//For the turtle
			int movet = (int)(Math.random() * 10) + 1;

Step back a bit and first fix your non-animation drawing code as you're doing a lot incorrectly starting with setting a background color. This is not done in the paint method itself. Next you appear to have program logic in the paint method -- another thing that you should never do. Next you seem to have your animation itself in the paint method, another thing you should never do.

I suggest that you go through some of the painting/drawing tutorials first to learn some of the rudiments of Java painting. Next consider using Swing rather than AWT. Then do your animation with a Swing Timer. Then you could delay the animation simply by increasing the Timer's delay property setting.

Oh ok! Thank you so much!
