This command will set the diffuse values of the specified sprite. The diffuse values controls the quantity of colour the sprite uses from each RGB component. The value ranges are 0 to 255, with 255 being completely full and 0 being no color use. If you only specified a value in the Red component, the sprite would appear a shade of red. Same goes for the other colours, and combinations of colour. The parameters should be specified using integer values.
Syntax:
SET SPRITE DIFFUSE Sprite Number, Red Value, Green Value, Blue Value
