public SpriteMaskInteraction maskInteraction ;


Specifies how the Particle System Renderer interacts with SpriteMask.

Particles by default do not interact with SpriteMasks and will be visible irrespective of any SpriteMask being present or not. Particle System Renderer can also be setup to be visible inside a mask by setting this value to VisibleInsideMask. The inverse can be achieved by seting the maskInteraction to VisibleOutsideMask. See Also: SpriteMaskInteraction.

void OnGUI() { maskInteraction = (SpriteMaskInteraction)GUI.SelectionGrid(new Rect(25, 25, 900, 30), (int)maskInteraction, new GUIContent[] { new GUIContent("No Masking"), new GUIContent("Visible Inside Mask"), new GUIContent("Visible Outside Mask") }, 3); } }
