Alias
alias
is a console command that allows a specified command to invoke one or several other commands. Aliases will only act for the game session they were defined in. However, keys bound can last if config.cfg
is not set to read-only. It is common for aliases to be defined in configuration files.

If no parameters are given, alias
will print a list of all aliases and their values.
Examples
After running the following command, typing foo
in the console will execute echo bar
alias foo "echo bar"
An example of an alias that toggles zoom. running ZoomToggle
will alternate between running +zoom
and -zoom
alias "ZoomON" "+zoom; alias ZoomToggle ZoomOFF" alias "ZoomOFF" "-zoom; alias ZoomToggle ZoomON" alias "ZoomToggle" "ZoomON"
An example of using aliases to increment/decrement the field of view. Note that running alias fovIN
makes the command fovIN
no longer do anything
alias "fov_85" "fov 85; alias fovIN; alias fovOUT fov_90" alias "fov_90" "fov 90; alias fovIN fov_85; alias fovOUT fov_95" alias "fov_95" "fov 95; alias fovIN fov_90; alias fovOUT" alias "fovIN" "fov_85" alias "fovOUT" "fov_95"
A common use of alias
is to run commands when a key is unpressed. for example, the following aliases can be used to test when alt
is pressed and unpressed to make alt + f4
exit the engine
bind alt "+alt_pressed" alias +alt_pressed "bind f4 exit" alias -alt_pressed "unbind f4"

alias healthpls "ent_fire !self addoutput "health 200"" //does not work

//This is the only line in file health_wrapper.cfg: ent_fire !self addoutput "health 200"
alias healthpls "exec health_wrapper.cfg" //works
Advanced Uses
The alias
command alone makes the source console Turing complete. In other words, it is able to simulate any computer calculation, meaning a command can be run based on an arbitrarily complex way that aliased commands were invoked. For example, an alias can run another command if the amount of times the alias was invoked previously was prime. There are many uses that are more practical.
