ParticleSystemRenderer.maskInteraction

描述

指定粒子系统渲染器如何与 SpriteMask 交互。

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. See Also: SpriteMaskInteraction.

using UnityEngine;
using System.Collections;

[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);
    }
