draw_surface_ext(id, x, y, xscale, yscale, rot, colour, alpha);
| Argument | Description |
|---|---|
| id | The unique id (index) of the surface to draw. |
| x | The x position of where to draw the surface. |
| y | The y position of where to draw the surface. |
| xscale | The horizontal scale. |
| yscale | The vertical scale. |
| rot | The rotation or angle to draw the surface. |
| colour | The colour with which to blend the surface. |
| alpha | The alpha transparency for drawing the surface. |
Returns: N/A
This function will draw the given surface as in the function
draw_surface but with
additional options to change the scale, blending, rotation and
alpha of the surface being drawn. Changing these values does
not modify the resource in any way (only how it is
drawn).
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_ext(surf, 0, 0, 2, 2, 0, c_red, 0.5);
The above code will draw a the surface indexed in the variable "surf" at the (0,0) position in the room, with twice the original scale, blended red and semi transparent.
