2d图片依次排列在屏幕中间（SpriteRenderer）

如图所示：

 c#代码：

 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>();  // 存储父物体的子对象
 7     list<float> rendererwidthlist = new list<float>(); // 存储子对象的宽度
 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; // 初始化长度
11 
12     void start () {
13         // 遍历所有子对象
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;  //第一个子对象的左边界
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 }

 

lua代码：
