标题: Unity 增加菜单选项之取得选择模型信息
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++)

            {

                SkinnedMeshRenderer skinnedMeshRenderer = (SkinnedMeshRenderer)skinnedMeshes[skinnedMeshIndex];

                totalMeshes.Add(skinnedMeshRenderer.sharedMesh);

            }
            for (int i = 0; i < totalMeshes.Count; i++)

            {

                Mesh mesh = (Mesh)totalMeshes;

                vertices += mesh.vertexCount;

                triangles += mesh.triangles.Length / 3;

                meshCount++;

            }

        }
        EditorUtility.DisplayDialog("Vertex and Triangle Count", vertices

            + " vertices in selection. " + triangles + " triangles in selection. "

            + meshCount + " meshes in selection." + (meshCount > 0 ? (" Average of " + vertices / meshCount

            + " vertices and " + triangles / meshCount + " triangles per mesh.") : ""),

    "OK", "");

    }

   

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

    public static bool ValidateShowCount()

    {

        return Selection.activeGameObject;

    }

}
