mp_grid_destroy(id);

返回： N/A

描述

You can use this function to destroy the indicated mp_grid and free up the memory allocated it. It is essential that you call this whenever the mp_grid is finished with or you could potentially get a memory leak, meaning that your game will slow down over time and eventually crash.

NOTE: Using mp_grid_* functions on a grid after it has been destroyed will result in an error!

例如：

if timer = 0
   {
   mp_grid_destroy(grid);
   room_goto(rm_Menu);
   }

The above code will destroy the mp_grid indexed in the variable "grid" if the variable "timer" is equal to 0, and then goto another room.
