Someone who is a Java developer please reply

How do I add a Thread.sleep() function to the JFrame’s
public void paint(Graphics g) area?
I know these forums are for Flash programmers but I can’t find anything that says how.

Personally I feel that while there are some java programmers, you would have been better off posting on a java board.

Yeah, but I don’t know of any Java boards.

The question is, why would you want to?

I’m making a tower defence game and I need to make it wait before spawning(painting) the next monster.

I recall hearing about this before…

You might have to sign up, but it is worth it. I used to ask a lot of questions here when programming Java.

Ok, thanks.

Firstly, you need to realize that creating an object and drawing a picture on the screen are two entirely different things.

Secondly, you don’t want to sleep the whole thread. That would make your application hang (and so the user could do absolutely nothing) until the next unit spawned, at which point it would promptly hang again.

You want to use a timer.

thanks, but how do I?

You look at the documentation.

It sounds like your jumping the gun on Java – you should probably take the time to learn Java and how games/animations/timed events are usually structured before you make your first game.

Note: You should probably consider using java.lang.Thread instead of javax.swing.Timer.

…why?

The Swing timer is far better for people new to programming, because it means you can just ignore threads and synchronization entirely. If you stick with the Swing timer, you can code it in much the same way as you would in Flash and it will just work – if you use threads or the Timer class in java.util, you have to keep in mind that anything you ask it to do will be executed on a separate thread, and it will trip you up if you ignore synchronization.
