Hello there
I have recently started Learning Actionscript 3.0 out of my own interest.
I was trying on making a ball bounce off the edges of the stage using the Actionscript 3.0. But the code not working.
The Ball happens to move on X and Y, till it hits the end of the stage, and then it just does not reverse its direction to give the effect of bounce, it gets stuck to the X axis and moves out of the stage.
I tried to make changes, but failed.
If some can tell me what may be the error, coz i am really not able to figure it out.
Thanks a lot in Advance
Here is the code…
