FillTextureArray()

void Terraria.ModLoader.ModUndergroundBackgroundStyle.FillTextureArray ( int[] textureSlots )

abstract

Allows you to determine which textures make up the background by assigning their background slots/IDs to the given array. BackgroundTextureLoader.GetBackgroundSlot may be useful here. Index 0 is the texture on the border of the ground and sky layers. Index 1 is the texture drawn between rock and ground layers. Index 2 is the texture on the border of ground and rock layers. Index 3 is the texture drawn in the rock layer. The border images are 160x16 pixels, and the others are 160x96, but it seems like the right 32 pixels of each is a duplicate of the far left 32 pixels.
