var arr = BinaryDataMgr.Instance.GetData("Height_" + levelId); int index = 0; Vector3 startPos = new Vector3(0, 0, 0); for (int i = 0; i < length; i++) { Vector3 pos = startPos; for (int j = 0; j < width; j++) { GameObject game = new GameObject(); game.transform.SetParent(GameObject.Find("Map").transform); game.transform.localPosition = pos; game.transform.localScale = new Vector3(Gridsize, arr[index] / 1000.0f, Gridsize); game.AddComponent<DrawHeightGround>(); pos.x += Gridsize; pos.y = 4; index++; } startPos.z += Gridsize; } 这段代码如何改成从左上角(0,0,0,)开始遍历格子

可以将 `startPos` 初始化为左上角的位置，即 `(0, 0, 0)`，然后在 `for` 循环中，先对 `j` 进行遍历，再对 `i` 进行遍历，这样就可以从左上角开始遍历格子了。修改后的代码如下：

var arr = BinaryDataMgr.Instance.GetData("Height_" + levelId);         
int index = 0;         
Vector3 startPos = new Vector3(0, 0, 0);         
for (int j = 0; j < width; j++)         
{             
    Vector3 pos = startPos;             
    for (int i = 0; i < length; i++)             
    {                 
        GameObject game = new GameObject();                 
        game.transform.SetParent(GameObject.Find("Map").transform);                 
        game.transform.localPosition = pos;                 
        game.transform.localScale = new Vector3(Gridsize, arr[index] / 1000.0f, Gridsize);                 
        game.AddComponent<DrawHeightGround>();                 
        pos.x += Gridsize;                 
        pos.y = 4;                 
        index++;             
    }              
    startPos.z += Gridsize;         
}
