u32 | color |
color in A8R8G8B8 Format |
Class representing a 32 bit ARGB color.
The color values for alpha, red, green, and blue are stored in a single u32. So all four values may be between 0 and 255. Alpha in Irrlicht is opacity, so 0 is fully transparent, 255 is fully opaque (solid). This class is used by most parts of the Irrlicht Engine to specify a color. Another way is using the class SColorf, which stores the color values in 4 floats. This class must consist of only one u32 and must not use virtual functions.
