WaterTexture

UT :: Object (UT) >> Bitmap >> Texture (UT) >> FractalTexture >> WaterTexture (Package: Fire)

UT2003 :: Object >> Material >> RenderedMaterial >> BitmapMaterial >> Texture >> FractalTexture >> WaterTexture (Package: Fire)

Abstract parent class for fractal water textures. Parent of Wave-, WetTexture and in UT2003 also FluidTexture.

Structs

ADrop

struct ADrop
{
    var WDrop Type;   // Drop type.
    var byte  Depth;  // Drop heat.
    var byte  X;      // Spark X location (0 - Xdimension-1).
    var byte  Y;      // Spark Y location (0 - Ydimension-1).

byte Y: Drop Y location (0 to height - 1).
byte ByteA, ByteB, ByteC, ByteD: Various (see effects above).
