How would I change this to do

Hello

First the task : I simply need to create a ‘screensaver’ in flash SWF format - of a company logo moving around the screen container and bouncing off the 4 walls, laws of physics etc wouldn’t really be necessary - the SWF just has to loop infinitely and the logo must keep moving.

I found a really nice project file from http://www.FreeActionScript.com - see attached. It is a very neatly coded and clearly commented project with a physics engine that creates a user - inputted amount of balls on screen in a container that float around the screen with full collision detection on the walls and on other balls. Big ups to the coder, whose name I can’t find in the comments.

For me something like this is truly impressive - and I thought myself able to change / greatly simplify the code to simply act on a movieclip of a logo I placed on stage - but just can’t get it right. I wish I could understand how someone codes something like this from the ground up, with constructors and physics and functions and and and… its been so long since I looked at code and its depressing me that I can’t solve this task…

Please could any kind soul describe to me what parts of the existing code files I should try change to get the existing physics engine to act on a movieclip logo that I would create (not yet created in the attached project) and not actually draw any balls at all?

kind regards
Mike
