Hey guys, i finally signed up for this site :)

I am wondering how to make the Y axis (scale) go up and down for several seconds.

I am aware of expressions and wiggles , but i am newish to after effects and have never wrote one before


I am animating a 3d rectangle thingy i want the top bit to bounce up and down.

A continuous bounce for 3D layer Y-scale would be something like this:

[100,100+10*Math.sin(time*10),100]

You obviously want to control when the bounce is happening and customize it otherwise, so you'll want to add some slider controls, minimally for the amplitude, possibly for frequency and phase as well.
