====== Texture animation group (DED) ======

//Group// definitions can be used to define texture animations such as the animated water in [[games:Doom]]. Alternatively they can also be used to tell the engine to cache all the textures of a group at the same time (e.g., switch textures) if they are likely to be needed quickly.


===== Limitations =====


One Group definition can only include Flat blocks or Texture blocks only.


===== Syntax =====

  
  <Copy> Group
  {
  	 Flags = flaga | flagb | flagc etc...
  		  # smooth: Interpolate/blend texture transitions.
  		  #
  		  # first_only: Only animate if the texture used in the map is the first
                    #             texture defined in this sequence.
                    #
  		  # precache: Cache all textures in this sequence at once.
  
  	 Flat
  	 {
  		  ID = ""
  		  # Name of the Flat lump eg FWATER1
  
  		  Tics = integer
  		  # How many tics to wait before moving onto the next Flat in the group
  		  # One second is equal to 35 Tics.
  
  		  Random = integer
  		  # How many additional randomized tics to wait before moving onto the
  		  # next Flat in the group
  		  # One second is equal to 35 Tics.
  	 }
  
  	 Texture
  	 {
  		  ID = ""
  		  # Name of the Texture lump eg SLADRIP1
  
  		  Tics = integer
  		  # How many tics to wait before moving onto the next Texture in the group
  		  # One second is equal to 35 Tics.
  
  		  Random = integer
  		  # How many additional randomized tics to wait before moving onto the
  		  # next Flat in the group
  		  # One second is equal to 35 Tics.
  	 }
  }



===== Examples =====

==== Animated Flat ====

  Group {
    Flags = smooth
    Flat { ID = "FWATER1" Tics = 8 }
    Flat { ID = "FWATER2" Tics = 8 }
    Flat { ID = "FWATER3" Tics = 8 }
    Flat { ID = "FWATER4" Tics = 8 }
  }


==== Animated Texture ====

  Group {
    Flags = smooth
    Texture { ID = "BLODGR1" Tics = 8 }
    Texture { ID = "BLODGR2" Tics = 8 }
    Texture { ID = "BLODGR3" Tics = 8 }
    Texture { ID = "BLODGR4" Tics = 8 }
  }
