In a throwback to Points Along A Line from several years back, here’s a quick expression for ya– “Point on a Circle.” Straightforward, yeah? Yeah.
offsetAmount = [0, 0]; circleRadius = 100; targetAngle = 0; x = offsetAmount + circleRadius * Math.cos(targetAngle); y = offsetAmount + circleRadius * Math.sin(targetAngle); [x, y]
The first three lines are just setting up the circle & any offset; how big is it, and where on the circle do we want the point to be? In the preset, these will be linked to controllers so you can pick a layer to orbit around, and easily control the angle & radius.
