解决ngui挡住粒子的问题

using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class ControlParticle : MonoBehaviour {

        public int renderQueue = 30000;
        public bool runOnlyOnce = false;  

        void Start()
        {
                Update();
        }  

        void Update()
        {
                if (renderer != null && renderer.sharedMaterial != null)
                {
                        renderer.sharedMaterial.renderQueue = renderQueue;
                }
                if (runOnlyOnce && Application.isPlaying)
                {
                        this.enabled = false;
                }
        }
}

把这段代码加到粒子上，然后调整renderQueue 即可
