试图引用数组中对象中的值，但失败

我花了几天时间尝试不同的技术来获得两个X乘Z数组彼此交谈，并决定通过制作2乘X乘Z数组来重做这一切。0,x,z包含一个立方体网格(预制单元)，它将存储稍后用于NPC导航的值，而1,x,z包含一个高长方体网格(预制ObstBlock)，用于检测场景中的墙壁。如果有墙，ObstBlock的int受阻将变成1。我试图在主脚本中引用的就是这个int。

所有的cell和obstblock都是由运行GridScript的空对象(名为"Grid")生成的。所有的cell运行CellScript，所有的obstblock运行ObstBlockScript。以下是我在GridScript中的尝试:

void DetectObstructions(){
    for (int x=0; x<GridSize.x; x++) {
        for (int z=0; z<GridSize.z; z++) {
            Transform cell;
            Transform block;
            cell = Grid [0, x, z];
            block = Grid [1, x, z];
            if (block.GetComponent<ObstBlockScript> ().Obstructed == 1) {
                cell.GetComponent<CellScript>().Weight = 1000;
            }
            else{
                cell.GetComponent<CellScript>().Weight = 500;
            }
            cell.GetComponent<CellScript>().Obstructed = block.GetComponent<ObstBlockScript>().Obstructed;
        }
    }
}

我没有得到错误，当我尝试使用调试工具时出现:这个请求不支持由被调试对象实现的协议版本。

根据要求，脚本的网格创建部分:

void CreateGrid(){
    Grid = new Transform[2,(int)GridSize.x,(int)GridSize.z];
    for (int x=0; x<GridSize.x; x++) {
        for (int z=0; z<GridSize.z; z++) {
            Transform newBlock;
            newBlock = (Transform)Instantiate (ObstBlockPrefab, new Vector3 (x/4f, 1.0f, z/4f), Quaternion.identity);
            //newBlock.name = string.Format("({0},1,{1})",x,z);
            newBlock.parent = transform;
            newBlock.GetComponent<ObstBlockScript>().Position = new Vector3(x/4f,1.0f,z/4f);
            Transform newCell;
            Grid[1,x,z] = newBlock;
            newCell = (Transform)Instantiate (CellPrefab, new Vector3 (x/4f, -0.125f, z/4f), Quaternion.identity);
            //newCell.name = string.Format("({0},0,{1})",x,z);
            newCell.parent = transform;
            newCell.GetComponent<CellScript>().Position = new Vector3(x/4f,-0.125f,z/4f);
            //if(GameObject.Find("ObstGrid").GetComponent<ObstructionScript> ().ObstGrid[x,z]./*GameObject.*/Find ("ObstBlock").GetComponent<ObstBlockScript>().obstructed == 1){
            //  newCell.GetComponent<CellScript>().Weight = 83;
            //}
            Grid[0,x,z] = newCell;
        }
    }
}
