Basic Scripting for Pydrivers

Hi All,

I was hoping someone could point me in the right direction for the basics of script writing for Pydrivers.

My interest was perked after watching a video by

on blendervideos.com here:

I use expressions for enhanced functionality in After Effects and I’d really like to know how to do this in Blender. Even if I could find somewhere with basic commands to get me started.

any help would be appreciated,
L

Here is the API link for 2.49 series. The 2.5 series has an incompatible new API.

I think pydrivers are only 1-line things, kind if like the original AE motion script was (I could be wrong). But you can also create a text document in your BLEND file and place entire functions that a pydriver can call to extend functionality.

Also, you may want to check out the frameChanged event as well. This is a way to simply run a script everytime the frame changes. Then you can operate on any object in the scene.

thanks Atom!

I’ll take a look at what you’ve suggested. I think this would be a greatly untouched portion of Blender that could use some Video Tuts for all you tutorial creators out there… hint hint… especially for users coming from a After Effects background.
