Limit Transformation??

CG-hi guys,

I’m having trouble rigging my typewriter. This is the plan:
Every time the button rotates (red line). The Cylinder (blue) need to move to the right. No matter how the button rotates (up or down) the cylinder needs to move to the right. But I cant get it done with the normal constraints. any idea’s?


Maybe something with driver’s… never understood that.

Python scripting i think probably is your only choice if you want it fully automated… Why?

Well, drivers and constraints dont work on a “No matter how the button rotates” situation… if you have it linked, if you move it one way it will be affected, if you move it back, it will go back to its resting position. You cant have it so that it only ever moves forward.

Thank you, I don’t know how to do that in python. I thought, maybe there was a constraint that makes the X location only can go up in valuea.

Well. i have to animate it then. Once again thank you for your anwser

Just put a driver on an empty. Move the driver in time to the key. That way you can return it also.driveronempty.blend (532 KB)You can change interpolation to suite.
