background_flush(array);
| Argument | Description |
|---|---|
| array | Array with the background indices to flush |
Returns: N/A
With this function you can remove any number of background
textures - and the texture pages they are assigned to - from video
memory (their texture pages will be reloaded on next use of any
background from them). You supply an array of background asset
indices and they will be removed from memory when the function is
called. It is worth noting that by default on the Windows
platforms (YYC and standard) all textures will always be loaded
into memory on start-up. If you are making a cross platform game,
then you can leave this function in your code for the Windows
target as it will not give any error and just not do anything.
However you can also force the Windows target to not load any
textures on startup and so use the flush and prefetch functions as
you would on all other platforms (the setting can be found in the
Windows Global Game Settings window).
bck_a[0] = bck_Trees;
bck_a[1] = bck_Clouds;
bck_a[2] = bck_Mountains;
bck_a[3] = bck_Tileset;
background_flush_multi(bck_a);
The above code creates an array where each element holds a background index. This array is then used to clear those background textures from memory.
