background_prefetch(ind);
| Argument | Description |
|---|---|
| ind | The background index to fetch |
Returns: N/A
This function can be used to prefetch (place into texture
memory) a texture page with the given background. You supply the
background index as defined when you created the background asset,
and the texture page it is on will be loaded into memory.
NOTE: There is a performance hit as the texture is uploaded to texture memory on most devices, so it's recommended that you call background_preftech on any required graphics at the start of a level to avoid any stalls.
background_prefetch(bck_Trees);
The above code will place the referenced background into texture memory ready for use.
