I want it to snap to 22 positions instead of just smooth movement. I there any way to actually do this?

var Snap = Math.round(A/22)*22;
Snap > MaxY? MaxY : 
Snap < MinY? MinY : Snap

A = Y position (of the mouse because I’m assuming it’s being dragged)

Something like that in an expression

Or actually that’s wrong, what you want is to see the Range,

maxY-minY = Range
Range/22

That just splits it into 22 segments. Then from there you can see how far it should move/snap to
