After inspecting Racer's rock crawler model in Torque ShowTool Pro, here's what I've found:
-Spring animations should be named after the used spring (spring0, spring1, etc)
Animation should move from up to down (least extended to most extended)
Should be 10 frames long? (unsure, I need to try this out)
So yeah, you've got most of it correct. I can't find anything releated to the animations in the Rock Climber's code, so I'd assume Torque handles all if it automatically.
Please keep in mind I still need to experiment with all this, so the above stated could be incorrect.
