TrailRenderer.maskInteraction

説明

Specifies how the TrailRenderer interacts with SpriteMask.

By default, trails do not interact with SpriteMasks and are visible regardless of whether you assign a SpriteMask or not. You can make the TrailRenderer visible either inside or outside a SpriteMask. To do the former, set this to SpriteMaskInteraction.VisibleInsideMask. To do the latter, set this to SpriteMaskInteraction.VisibleOutsideMask. See Also: SpriteMaskInteraction.

    {
        r.maskInteraction = maskInteraction;
    }
