public SpriteMaskInteraction maskInteraction;

Description

Specifies how the Particle System Renderer interacts with SpriteMask.

By default, particles do not interact with SpriteMasks and are visible regardless of whether you assign a SpriteMask or not. You can make the ParticleSystemRenderer 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. Additional resources: SpriteMaskInteraction.

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { private ParticleSystemRenderer psr; public SpriteMaskInteraction maskInteraction;

void Start() { psr = GetComponent<ParticleSystemRenderer>(); }

void Update() { psr.maskInteraction = maskInteraction; }

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); } }
