This function can be used to convert a string which has been created previously by the function ds_grid_write() back into a ds_grid. The ds_grid must have been created previously (see the example below). 请注意，如果数据结构是使用以前的版本创建的GameMaker你应该添加可选参数“legacy”，将其设置为true，因为此版本的字符串格式已更改。
ds_grid_read(index, string [, legacy]);
| 参数 | 描述 |
|---|---|
| index | The index of the grid to read. |
| string | The string to read into the ds_grid. |
| legacy (optional) | 可以是 true 或 false 或完全省略。 |
N/A（无返回值）
grid = ds_grid_create(room_width div 32,
room_height div 32);
ini_open("Save.ini");
ds_grid_read(grid, ini_read_string("Save", "0", ""));
ini_close()
The above code creates a ds_grid based on the size of the room (each 32x32 square of pixels represents one grid cell) and then reads a previously saved set of grid data from an ini file into the new ds grid.
