Unity 增加菜单选项之取得选择模型信息

奔跑的小兔

有用的编辑器扩展！

///新建名称为MeshInfo 的CShape文件，然后添加如下代码。会新建一个菜单Custom-》Show Mesh Info ，当在Hierarchy中选有物体时点击，
//可显示模型信息
using UnityEngine;

using UnityEditor;

using System.Collections;

/*

所有选择物体的总定点数，三角面数，选择模型数目，每个模型平均的定点数目和三角面数

*/

public class MeshInfo : ScriptableObject

{   

    [MenuItem ("Custom/Show Mesh Info %#i")]

    public static void ShowCount()

    {

        int triangles = 0;

        int vertices = 0;

        int meshCount = 0;

        

        foreach (GameObject go in Selection.GetFiltered(typeof(GameObject), SelectionMode.TopLevel))

        {

            Component[] skinnedMeshes = go.GetComponentsInChildren(typeof(SkinnedMeshRenderer)) ;

            Component[] meshFilters = go.GetComponentsInChildren(typeof(MeshFilter));
            ArrayList totalMeshes = new ArrayList(meshFilters.Length + skinnedMeshes.Length);
            for (int meshFiltersIndex = 0; meshFiltersIndex < meshFilters.Length; meshFiltersIndex++)

            {

                MeshFilter meshFilter = (MeshFilter)meshFilters[meshFiltersIndex];

                totalMeshes.Add(meshFilter.sharedMesh);

            }
            for (int skinnedMeshIndex = 0; skinnedMeshIndex < skinnedMeshes.Length; skinnedMeshIndex++)
