CloseSets pixel color at coordinates (x,y).
Call Apply to actually upload the changed pixels to the graphics card.
Uploading is an expensive operation, so you'll want to change as many pixels
as possible between Apply
calls.
If you're constantly regenerating a texture at runtime, it may be faster
to generate an array of pixel colors and set all of them at once with SetPixels.
This function works only on RGBA32
, ARGB32
, RGB24
and Alpha8
texture formats.
For other formats SetPixel
is ignored.
The texture also has to have read/write enabled flag set in the texture import settings.
