Recently I’ve found myself using a lot of Gizmos in Unity , to such an extent that it became worthwhile to have some quick and easy component to re-use rather than scripting up the same OnDrawGizmos call repeatedly.
So here it is, SimpleGizmoDisplay. It currently supports Cube, WireCube, Sphere, WireSphere, Icon and Line. It’s quick and bare-bones, but it can save a lot of time in pretty short-order.
Do with it as you wish!
