Done, go here.

I know it's supposed to be simple and I am ashamed I didn't figure it out yet

But what's the trick again to convert two 2d points to a rotation value? I want to convert a directional vector to a rotation value, and here's what I've got:

Code: Select all

```
// Get positions
Layer1 = thisComp.layer("PosLayer")
Pos1 = Layer1.toWorld(Layer1.anchorPoint);
Pos2 = Layer1.toWorld(Layer1.anchorPoint.valueAtTime(framesToTime(timeToFrames()-1)));
delta = Pos2 - Pos1;
radiansToDegrees(Math.atan2(delta[1],delta[0]));
```
