Half-Life Console Commands and Variables

Category: unknown

Use these console commands and variables to customize Half-Life, TFC, Opposing Force, or most HL Mods, troubleshoot problems with video or sound hardware, optimize performance, or make your own scripts. If you don't know how to use these console commands and variables, please see the Console Tutorial. Many of these variables are boolean, which means that they can be either 1 (on) or 0 (off) and no other values are allowed. In the descriptions for boolean variables, I use "enables" or "disables" to indicate what happens when that variable is set on (1). The opposite is always true (if 1 enables the feature, 0 disables it, and vice-versa). Variables that can accept any number as a value have descriptions that begin with "sets the . . . " 

Be sure to check out the other categories, especially the tweaks!. The flags listed at the end of the descriptions of some variables have the following meanings: 

  • a - attribute variable, changes to these variables will be automatically saved to Half-Life/valve/config.cfg (or Half-Life/tfc/config.cfg for TFC). Variables without this flag will return to the default value listed unless set by Half-Life/valve/autoexec.cfg (or Half-Life/tfc/autoexec.cfg for TFC).
  • i - info variable, the values of these variables are displayed in response to the info command. 
  • sv - server info variable, the values of these variables are displayed in response to the serverinfo command. 
  • tfc - team fortress classic variables, these variables apply to TFC mode only (hl.exe -game tfc).
