Move Layer on Angle
Hi everyone,
I’m sure Dan knows the immediate answer to this, but just in case someone wants to try beating him to the punch, here’s what I’m trying to achieve:
I need a simple way of moving a layer on an angle. Essentially, I’d like to have two sliders on a footage layer: one for X-position, and one for angle. As I set keyframes and animate the X-position of a layer, I would like the Y-position to automatically increase/decrease in a way that makes the layer appear to be sliding on the defined angle. I’ve tried rigging my own solution by using the tangent of a given angle, but that didn’t seem to work.
Any and all help would be appreciated.
Thank you!

Will you be animating the angle? If so, that’s a much more complicated expression because you’ll need to calculate where the layer was at each of the previous keyframes.

Hi Dan,
No, it would be great for the angle to be constant. No animation needed 🙂
Thank you!

Play around with this and see if it’s close:
x = effect(“x”)(“Slider”);
a = effect(“angle”)(“Slider”);
y = -x*Math.tan(degreesToRadians(a));
value + [x,y]Dan
