With this function you can define an area within a given ds_grid, then take those values and multiply them with those found in a separate region of either the same ds_grid, or another one (which has been previously created). The original region will remain unchanged, while the region that they have been multiplied with will now store the new values for each cell.
ds_grid_multiply_grid_region(index, source, x1, y1, x2, y2, xpos, ypos);
| 参数 | 描述 |
|---|---|
| index | 靶栅格的索引 |
| source | 源栅格的索引 |
| x1 | 从源栅格复制的单元格区域的左端位置 |
| y1 | 从源栅格复制的单元格区域的顶端位置 |
| x2 | 从源栅格复制的单元格区域的右端位置 |
| y2 | 从源栅格复制的单元格区域的底端位置 |
| xpos | The x position on the destination grid to multiply the source region with. |
| ypos | The y position on the destination grid to multiply the source region with. |

ds_grid_multiply_grid_region(mygrid, mygrid, 0, 0,
5, 5, 0, 0)
This would take the region of cells from (0,0) to (5,5) of the ds_grid "mygrid" and multiply them with the cells from position (0,0) of the same ds_grid.
