annoying question for DE
Hey, Dan!
How come an object using your bounce expression doesn’t seem to consistantly hit exactly the same spot when it bounces? It’s a beautiful expression, but why is this so?thanks in advance

It’s hard to say without seeing exactly what you’re doing, but sometimes the bottom of the bounce occurs between frames. Depends on the bounce frequency and your frame rate. The result is that sometimes it looks like it doesn’t quite hit bottom.

[Dan Ebberts] “sometimes the bottom of the bounce occurs between frames”
Yeah … that’s what I was thinking, but I kept doing variations and looking at it over and over (probably looking at it too much … hmmm … my eyes hurt) and was convinced that it wasn’t really doing this. Am I madder than a hatter? Perhaps.
This just in: I just made a project that has a very odd error trying to ‘compile’ that expression. Here’s a link to the project file:

If you want (oh, please do), download this proj and see if this gives you the same error it gave me (“After Effects warning: Timeout waiting for the engine.
Error occurred at line 16.
Expression disabled.”). And sometimes, it says line 18! No kiddin’. Now, this is the expression copied and pasted from another comp that works perfectly. No kiddin’ again!This is in ae v6.5.1, OSX 10.4.6

I think the problem is just that you have the ball positioned below the “floor”. Either move the ball up or increase the value of “floor”.
