|ind||The sprite index to fetch|
This function can be used to prefetch (place into texture
memory) a texture page with the given sprite. You supply the sprite
index as defined when you created the sprite 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 sprite_prefetch on any required graphics at the start of a level to avoid any stalls.
The above code will place the referenced sprite into texture memory ready for use.
