Java Applet Flickering Problem...[Done]

[Josh]

I have created this applet in java with gif images that are animated and my applet flickers really bad. Is there anyway I can fix this and how?

Here is my code so far:

Does anyone have any idea how to stop my applet from flickering really bad I tried double buffering and repainting but I don't think I got the code right or something before so I removed it....Any help is appreciated. Thanks

Well, you are the "Support Professional" can we get a link to it in action? Otherwise maybe this would fare better in the programming board?

Flickering in animations is generally caused due to lack of buffering. Unfortunately I don't know Java, nor do I care to research the disease of a language. But I will explain to you what double buffering is.

Double buffering means that instead of drawing straight to the screen/window/whatever-output-you're-using, you draw to a temporary buffer (a GIF, BMP, etc. etc.) and then draw that temporary buffer to the screen. So what you'd want to do is create an image (the buffer) the size of the screen and output all of your images to that. And at the end, you output the buffer to the screen.

This will reduce the number of times you're updating the screen, thus making the animation smoother.

Thanks, I know what double buffering is and I have tried to use it but I haven't had to luck so I deleted it from my code...I think I probably set it up wrong...

Can anyone help me lol or am I stuck? Thanks

Try taking this discussion to the General Programming Discussion board, you are more likely to get a response from there as this board is mainly concerned about JavaScript.

If you wish, the topic can be moved across for you.

Yes, please move my topic for me if you don't mine. I get confused on which boards here or for what lol

Thanks you so much
