surface_free(surface_id);
| Argument | Description |
|---|---|
| surface_id | The ID of the surface to be freed. |
Returns: N/A
When you are working with surfaces, you should always use this
function whenever you are finished using them. Surfaces take up
space in memory and so need to be removed, normally at the end of a
room, but it can be done at any time depending on the use you put
them to. Failure to do so can cause memory leaks which will
eventually slow down and crash your game.
NOTE: When working with surfaces there is the possibility
that they can cease to exist at any time due to them being stored
in texture memory. You should ALWAYS check that a surface
exists using surface_exists before
referencing them directly. For further information see Surfaces.
if keyboard_check_pressed(vk_escape)
{
surface_free(surf);
room_goto(rm_Menu);
}
The above code checks for a key press and if it detects one it frees the memory reserved for the surface indexed in the variable "surf" and then changes room.
