draw_surface_part(id, left, top, w, h, x, y );
| Argument | Description |
|---|---|
| id | The unique id (index) of the surface to draw. |
| left | The left position in the surface of the part to be drawn. |
| top | The top position in the surface of the part to be drawn. |
| w | The width of the part to be draw, from left. |
| h | The height of the part to be drawn, from top. |
| x | The x position of where to draw the surface. |
| y | The y position of where to draw the surface. |
Returns: N/A
With this function you can draw part of any surface at a given
position within the room. As with draw_surface you can specify a
surface, but you then need to specify the relative
coordinates within the surface of an area to select for
drawing. This means that a left position of 0 and a top position of
0 would be the top left corner of the surface and all further
coordinates should be taken from that position.
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.
draw_surface_part(surf, 8, 8, 32, 32, x, y);
This will draw a 32x32 area 8px by 8px in from the top left of the surface indexed in "surf", at the instances (x,y) position.
