surface_get_height

This function simply returns the height, in pixels, of the indexed surface. It should be noted that if you call this to check the application_surface immediately after having changed its size using surface_resize() it will not return the new value as the change needs a step or two to be fully processed. After waiting a step it should return the new size correctly.

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.

Syntax:

surface_get_height(surface_id);

Returns:

Real

Example:

sh = surface_get_height(surf);

The above code will store the height of the surface indexed in the variable "surf" in the variable "sh".
