2d圖片依次排列在屏幕中間（SpriteRenderer）

如圖所示：

 C#代碼：

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class SpriteRendererTest : MonoBehaviour {
 6     List<Transform> list = new List<Transform>();  // 存儲父物體的子對象
 7     List<float> rendererWidthList = new List<float>(); // 存儲子對象的寬度
 8     private Vector3 centerPos = Vector3.zero;  // 中心位置
 9     private float offSet = 0.2f; //偏移量
10     private float length = 0.0f; // 初始化長度
11 
12     void Start () {
13         // 遍歷所有子對象
14         for (int i = 0; i < gameObject.transform.childCount; i++) {
15             var child = gameObject.transform.GetChild(i);
16             var width = child.GetComponent<SpriteRenderer>().sprite.bounds.size.x;
17             if (i < gameObject.transform.childCount - 1)
18             {
19                 length += width + offSet;
20             }
21             else {
22                 length += width;
23             }
24             list.Add(child);
25             rendererWidthList.Add(width);
26         }
27         var startX = centerPos.x - length / 2.0f;  //第一個子對象的左邊界
28         foreach (var child in list)
29         {
30             int index = 0;
31             child.transform.position = new Vector3(startX + rendererWidthList[index] / 2.0f, 0, 0);
32             startX = startX + offSet + rendererWidthList[index];
33             index += 1;
34         }     
35     }
36 }
