// A script to make an object move in a perfect circle
// argument0 is x coordinate of center
// argument1 is y coordinate of center
// argument2 is radius of circle
// argument3 is angular speed. Positive is
// clockwise, negative counterclockwise
// This is the corner to turn a step. For instance
// 5 means it will turn around in 360/5 = 72 steps
// This script requires GM 5.1 or higher
