Animate script for custom rigged characters?

Is there any way i could make an animate script for custom rigged characters?

I have already tried just copying the "animate" script from my character, but my rig doesn't have the same joints / body parts, so the animations don't play.

I also tried copying the script and changing the value for the walk animation, but that didn't work either, and it ended up just not playing.

Does anyone know how I could do this?

Sorry if this is dissappointing but, If it's a custom rigged character, it really wont work, unless you have the same bodyparts. You'll need to make your own animation.
