不知道場景裡多少面,把指令碼放進去執行一下即可,方便優化專案程式碼如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// 獲取場景的頂點數跟面數  ******************掛在場景上執行即可******************
/// </summary>
public class CeShiMian : MonoBehaviour
{
    public static int verts;
    public static int
 
 tris;
    // Use this for initialization
    void Start()
    {      
        GetAllObjects();
    }
    /// <summary>
    /// 得到場景中所有的GameObject
    /// </summary>
    void GetAllObjects()
    {
        verts = 0;
        tris = 0;
        GameObject[] ob = FindObjectsOfType(typeof(GameObject)) as GameObject[];
        
 
foreach (GameObject obj in ob)
        {
            GetAllVertsAndTris(obj);
        }
    }
    //得到三角面和頂點數
    void GetAllVertsAndTris(GameObject obj)
    {
        Component[] filters;
        filters = obj.GetComponentsInChildren<MeshFilter>();
        foreach (MeshFilter f in filters)
        {
            tris 
 
+= f.sharedMesh.triangles.Length / 3;
            verts += f.sharedMesh.vertexCount;
        }
    }
    void OnGUI()
    {
        GUIStyle bb = new GUIStyle();
        bb.normal.background = null;    //這是設定背景填充的
        bb.normal.textColor = new Color(1.0f, 0.5f, 0.0f);   //設定字型顏色的
        bb.fontSize = 40;       //當然，這是字型大小
        string vertsdisplay = verts.ToString("#,##0 verts-頂點數");
        GUILayout.Label(vertsdisplay,bb);
        string trisdisplay = tris.ToString("#,##0 tris-面數");
        GUILayout.Label(trisdisplay,bb);
       
    }
