## **ds_grid_set**
**设置网格结构中一个单元格的值。**
**语法:**
ds_grid_set(index, x, y, value);
| 参数 | 描述 |
| --- | --- |
| index | 网格索引 |
| x | 要设置的单元的x位置 |
| y | 要设置的单元的y位置 |
| value | 需要设置的值 |
**返回:** N/A
#### **描述**
这个函数可以让指定的实数或字符串(扩展备注:其实也可以是数组或者数据结构,官方没说但是确实可以用)填充在指定的单元格内. 下面图片能很好的展示它是如何工作的:

#### **举例:**
~~~
grid = ds_grid_create(5, 5);
var i, j;
i = 0;
j = 0;
repeat (ds_grid_width(grid))
{
repeat (ds_grid_height(grid))
{
ds_grid_set(grid, i, j, irandom(9));
j += 1;
}
j = 0;
i += 1;
}
~~~
上面的代码创建一个网格结构。 然后用从0到9的随机整数填充这个网格。
#### **扩展举例:**
~~~
grid = ds_grid_create(5, 5);
grid[# 2,3] = 10;
~~~
上面的代码创建一个网格结构。 然后在2,3位置处设置数值为10(下标是和数组相同以0开始的,所以这里是第三个格子)。这是一个使用访问器快速访问网格结构的方法,会有很多例子使用此类方法(它有点类似于数组)。
