Making an actor rotate right, pause, rotate left, then repeat!

ColorplayGames

Hello!
I have an actor that I would like to do the following:
1) Start with no rotation
2) Start rotating right, speed up, slow down until no more rotation
3) start rotating left, speed up, slow down until no more rotation (in other words, ease in and out)
4) repeat!

I'm sure I could do this with timers or something similar but I was wondering if anyone knew any fancy math equations that might help me out

Thanks for the help!

You could probably do something with the pacing guide using rotate instead of movement.
The logic would be the same as far as the equation.

You would use a mix of Interpolate (to control the Rotation) and Timers (to control the timing of the Rotations).

If you want to do it mathematically, you would need to use trig.
This post describes the motion of a pendulum, which is sort of similar:

If the trig is beyond you, I would stick to the Timers and Interpolation. It will give you more control over the look and feel of it.

I will check those out - thanks so much!
