在每个需要排序的物体上放入GridTag 脚本 其中GridTag脚本用于提供此物体的深度
using UnityEngine;
using System.Collections;
using UnityEngine.UI; public class GridTag : MonoBehaviour
{
private int depth = ; public int Depth
{
get
{
return depth;
}
} void Awake()
{
FindDepth(transform); Debug.Log("当前深度"+depth);
} void FindDepth(Transform trans)
{
if (trans.parent != null)
{
depth--;
trans = trans.parent;
FindDepth(trans);
}
}
}
Sorting 通过GridTag 和 其中的深度值 排序
