NGUI Mesh 粒子 Spine 层级解决方案
render order Vs render queue
ngui 层级排序原理
代码实现
本质就是把 mesh 的渲染序列加入到uipanel里面，粒子也是一样
RenderQueueModifier.cs
using UnityEngine;
using System.Collections;
public class RenderQueueModifier : MonoBehaviour {
///必须设置 或者 由代码设置
public UIPanel m_panel;
public UIWidget m_target;
public bool isForSpine = true;
public Renderer renderer;
public SkeletonRenderer skeletonRender;
void Awake() {
if (isForSpine) {
skeletonRender = GetComponent();
}
else {
renderer = GetComponent();
}
}
void OnEnable() {
AddToPanel();
}
public void Set(UIPanel m_panel, UIWidget m_target, bool isForSpine)
{
this.m_panel = m_panel;
this.m_target = m_target;
this.isForSpine = isForSpine;
AddToPanel();
}
void AddToPanel() {
if (m_panel != null) m_panel.renderQueueModifiers.Add(this);
}
void OnDisable() {
m_panel.renderQueueModifiers.Remove(this);
}
int lasetQueue = int.MinValue;
public void setQueue(int queue)
{
if (this.lasetQueue != queue) {
this.lasetQueue = queue;
if (isForSpine){
skeletonRender.needControllerRenderQueue = true;
skeletonRender.renderQueue = this.lasetQueue;
}
else {
renderer.material.renderQueue = this.lasetQueue;
}
}
}
}
