how to create run time gizmos like in unity editor
Unity Gizmos are helpers they will only display in Unity Scene Window or Game Window.If you want to draw gizmos for your scripts,use ‘void OnDrawGizmos()’ which will render gizmos like sphere,line and box (shaded and wire) in both scene view and game view.If you meant to create gizmos which shows in build,you have to create your own using quads which faces camera or something like line renderer.
