surface_set_target_ext(index, surface_id);
| Argument | Description |
|---|---|
| index | The render target index to use (from 0 to 3). |
| surface_id | The ID of the surface to use. |
Returns: Boolean
This function is for use with the Shader Functions and sets the MRT (0 -
3) for native level shaders (DX9, DX11, OpenGL).
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.
surface_set_target_ext(0, surf);
The above code will set the render target 0 to the surface ID indexed in the variable "surf".
