## **網格** ds_grid基本上是一種二維數組。通過設置其整數寬度和高度來定義，以此來設置網格中“單元格”的總數(寬度和高度相乘)，然后使用這些單元格來保存不同的數據(實數或字符串)。 這種類型的結構允許您通過給出它的x和y索引來設置和檢索網格中的單元格值(從x和y軸開始為0，最大數值為寬度減1和高度減1)。同時，您還可以對特定的網格區域設置一個值值或者加上一個值，并在還可以對給定區域檢索總和、最大值、最小值和平均值，這些特性使得該數據結構成為所有可用的數據結構中最為通用的。 當訪問網格數據結構時，您應該始終嘗試對單元格位置使用整數，否則所有非整數索引都會被GameMaker Studio 2覆蓋。如果這不是您的需求，那么在傳遞您希望檢查的索引之前，您需要先對自己進行舍入。 **注意:** 與所有動態資源一樣，數據結構占用內存，因此在不再需要的情況下防止內存泄漏這些數據結構應該被銷毀，因為內存泄漏將會減慢并最終導致您的游戲崩潰。 * * * * * 下面是處理網格的函數： * [ds_grid_create](ds_grid_create.md) * [ds_grid_destroy](ds_grid_destroy.md) * [ds_grid_width](ds_grid_width.md) * [ds_grid_height](ds_grid_height.md) * [ds_grid_resize](ds_grid_resize.md) * [ds_grid_clear](ds_grid_clear.md) * [ds_grid_set](ds_grid_set.md) * [ds_grid_set_disk](ds_grid_set_disk.md) * [ds_grid_set_grid_region](ds_grid_set_grid_region.md) * [ds_grid_set_region](ds_grid_set_region.md) * [ds_grid_shuffle](ds_grid_shuffle.md) * [ds_grid_sort](ds_grid_sort.md) * [ds_grid_get](ds_grid_get.md) * [ds_grid_get_max](ds_grid_get_max.md) * [ds_grid_get_mean](ds_grid_get_mean.md) * [ds_grid_get_min](ds_grid_get_min.md) * [ds_grid_get_sum](ds_grid_get_sum.md) * [ds_grid_get_disk_max](ds_grid_get_disk_max.md) * [ds_grid_get_disk_mean](ds_grid_get_disk_mean.md) * [ds_grid_get_disk_min](ds_grid_get_disk_min.md) * [ds_grid_get_disk_sum](ds_grid_get_disk_sum.md) * [ds_grid_add](ds_grid_add.md) * [ds_grid_add_region](ds_grid_add_region.md) * [ds_grid_add_disk](ds_grid_add_disk.md) * [ds_grid_add_grid_region](ds_grid_add_grid_region.md) * [ds_grid_multiply](ds_grid_multiply.md) * [ds_grid_multiply_disk](ds_grid_multiply_disk.md) * [ds_grid_multiply_region](ds_grid_multiply_region.md) * [ds_grid_multiply_grid_region](ds_grid_multiply_grid_region.md) * [ds_grid_value_exists](ds_grid_value_exists.md) * [ds_grid_value_disk_exists](ds_grid_value_disk_exists.md) * [ds_grid_value_x](ds_grid_value_x.md) * [ds_grid_value_y](ds_grid_value_y.md) * [ds_grid_value_disk_x](ds_grid_value_disk_x.md) * [ds_grid_value_disk_y](ds_grid_value_disk_y.md) * [ds_grid_copy](ds_grid_copy.md) * [ds_grid_read](ds_grid_read.md) * [ds_grid_write](ds_grid_write.md) 除了這些特定的函數，你可以使用一個表達式（稱為訪問器）來添加或修改你的ds_grid的內容。此訪問器語法看起來類似于二維數組： ~~~ grid_index[# xpos, ypos] ~~~
