virtual int ChooseCloseTexture (ref float scale, ref double parallax, ref float a, ref float b)
 Allows you to determine which texture is drawn in the closest part of the background. This also lets you modify the scale and parallax (as well as two unfortunately-unknown parameters). More...
 
virtual int ChooseFarTexture ()
 Allows you to determine which texture is drawn in the very back of the background. BackgroundTextureLoader.GetBackgroundSlot may be useful here, as well as for the other texture-choosing hooks.
 
virtual int ChooseMiddleTexture ()
 Allows you to determine which texture is drawn in the middle of the background.
 
abstract void ModifyFarFades (float[] fades, float transitionSpeed)
 Allows you to modify the transparency of all background styles that exist. In general, you should move the index equal to this style's slot closer to 1, and all other indexes closer to 0. The transitionSpeed parameter is what you should add/subtract to each element of the fades parameter. See the ExampleMod for an example.
 
virtual bool PreDrawCloseBackground (SpriteBatch spriteBatch)
 Gives you complete freedom over how the closest part of the background is drawn. Return true for ChooseCloseTexture to have an effect; return false to disable tModLoader's own code for drawing the close background.
