Alias

Overview

alias is a console command that creates a new command. It takes two arguments, the first being the name of whatever command you are creating, and the second argument are the other commands that will make up your new command. They are incredibly powerful, but are forgotten by the game upon closing, so they are perfect for an autoexec.

For example, alias "defaultviewmodel" "viewmodel_offset_x 0; viewmodel_offset_y 0; viewmodel_offset_z 0" creates a new command inside of Portal 2 called "defaultviewmodel", and typing this command will set all viewmodel offsets to 0.

Types of Examples

Standard Alias

You can add multiple functionalities to an alias, there is no limit, so long as the commands do not act as a script and follow the rules for both SRC and iVerb.

Format

  • alias name "functionality1; functionality2; etc"
  • bind key name

Change Commands

A change command is typically made of three aliases, and designed to be used as a one-key bind that toggles functionality by redefining the core alias.

Format

  • alias change on
  • alias on "functionality; alias change off"
  • alias off "functionality; alias change on"
  • bind key change

Action Commands

An action command consists of two aliases of the same name, differentiated by the prefix + or -. Binding a key to the + variant will keep the functionality active while the button is held down. Releasing the key enacts the - variant. 

Note: iVerb rules forbid binding of multiple actions to one key, including using aliases. Read more bellow.

iVerb Rules doc

Format

  • alias +action "functionality"
  • alias -action "functionality"
  • bind key +action
