====== Console variable ======


//Console variables// (cvar) are variables "built-in" to the engine. The direct way to change and/or query their values is with the command line interface of the [[console]]. Most variables accept values only within a preset range appropriate for that variable.

{{note|The most commonly changed variables can also be adjusted from the [[control_panel]] GUI.}}


===== Examples =====

Displaying the value of the variable {{var|con-fps}} in the console:
  vid-fps

Displaying {{cmd|help}} information for the variable {{var|con-move-speed}}:
  help con-move-speed

Changing the value of the variable {{var|con-completion}} from the console (to **1**):
  con-completion 1

Changing the value of the variable {{var|rend-particle-rate}} with **force** from the console (to  **10**):
  rend-particle-rate force 10

{{note|Forcing the value of a variable is not generally a good idea. Doing so tells Doomsday to ignore the predetermined accepted value range and sets the value regardless. This feature exists primarily for development purposes.}}

Querying the value of the variable {{var|con-snapback}} and using the {{cmd|if}} command to generate a status message:
  if con-snapback = 0 "Console snapback is disabled" "Console snapback is enabled"
