DOME

If this flag is set, the sky sprite texture is tiled and projected vertically onto an imaginary sky dome at all places where a sky texture is assigned to a surface in the map. Due to the vertical projection, only the upper part of the sky is undistorted - the horizon must be rendered with a different sky element. The 'steepness' of sky domes can be set through the global sky_curve variable.

Sky domes can be used for stars or for layers of moving clouds, using the u/v parameters for the cloud layer speed . The scale of the texture is given by the scale_x parameter. The texture must be a power of two in size, and edges must match seamlessly. If the sky entity contains several frames (indicated by a '+' in the image name), they are displayed one over each other as cloud layers.

Type:

flag (flags2, sky definition only)

Example (lite-C):


ENTITY* skyClouds =
{
  type = "skyblue+2.tga"; 
  layer = 3;	
  scale_x = 0.25;	
  tilt = -10;	
  u = 1.5;
  v = -1.0;
  flags2 = DOME | VISIBLE;	
}
