Reviving a 5 year old thread for hopefully another requirement of rotations using expressions. I wasn't able to gather much from the discussion held previously, so here is my question.
Question: How do we use expressions to rotate an already existing rotation by a certain number of times?
Details: I have a cylinder (as a wheel) with radius equal to 36 and I generate continuous rotation by autokeying and rotating at the last frame for 360 degrees. I have made a plane as a road which is 3500 units long. Now from the beginning of the road till the end the wheel will have to rotate something like 15.47 times before it can stop (after certain maths).
Now all these calculations seem unnecessary but now if I can multiply my already existing rotation into 15.47 (using Expressions like how we do in Wire Parameters) and place the wheel at the end of the road, it would display actual rotation covering the entire length of road and wouldn't be sliding now at any point.
So how do we use expressions to rotate an already existing rotation by a certain number of times?
