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 your 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 greet in the console will execute say hello!
alias greet "say hello!"
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 FoVxIN makes the command FoVxIN 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"
Warning:An alias doesn't work if the command it is set to invoke has quotation marks. (alias does not support quotation marks inside quotation marks.)alias healthpls "ent_fire !self addoutput "health 200"" //does not work
Workaround:Create a separate file containing that lone command and set alias to exec the file.//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 set of alias calls. For example, an alias command can call another command if a different alias command was run n times, as long as n is prime.
There are many uses that are more practical.
