Engine development

This is a reference for Engine console commands available for use a chat window or other console, and as macro commands in a macro.

This list describes all of the slash commands, console commands and console variables from Engine itself, in one list for now, and not ones from any additional components or AddOns. These same commands are available in the base Engine scripting language.

Notes

  • By default, the console can be opened by pressing the 'back tick' (`) and exited by pressing escape (Esc).
  • If in a chat type box, commands can be run by starting with a forward slash (/) before the command line, to separate them from actual chat.

Key

  • 'Global commands' and 'Global variables' - Used below, are short-hand for commands placed in the 'global' context.
  • 'Default command' - Is run by default, if its context is addressed by name or is the current context. Examples:
    • var bob fred; bob
      Prints 'fred'. The 'var' command is used ot create a new variable, then the next statement uses the 'global' default 'varedit' command to print the value of 'bob'. 'bob' is not a command but an existing variable.
    • bob james; bob
      Prints 'james'. In the first statement, the global default command 'varedit' finds the existing 'bob' variable in the 'global' context, and assigns 'james'. In the next statement, the default command finds and prints the value of variable 'bob'.
  • Context - A script or command context. Each context may have its own commands and variables and rules. Examples:
    • client start
      Starts the client module.
    • context client; start; context global
      Starts the client module and returns to global.
    • lua print(1 + 3)
      Prints '3'. The 'lua' context is addressable from 'global'. The default command 'lua_edit' in the 'lua' context, runs the lua statement in the Lua runtime, where the 'print' is a real Lua statement, not an Engine script one.
    • context lua; print(1 + 3); exit
      Also prints '3' and returns to 'global'. Where the 'lua' context is switched to first, then the Lua command is run unqualified also using the default 'lua_edit' command.
  • Command - An engine module command, also referred to as a 'CCmd'.
  • Variable - An engine variable, similar to 'CVars' or config vars.
  • Alias - An alias or macro which is a string of script.
  • Binding - key bindings to the keyboard or mouse buttons, or from other real or virtual devices.
  • Associations - Module or context associations and features.
  • Service - An engine messaging service. Which may be internal, local, or network for send or receive.
  • Script - May refer to the base Engine script language, which can contain elements here. Or to strings of commands for an alias, or integrated higher-level scripting like blended in-line engine script with lua, JS, or C#.
  • Module - An independent static module built into the engine.

Reference

In Engine, commands are divided into sets defined by modules. Some commands are always available by default. Others are only available by setting console context to that module first. In some modules, there can be a default command that gets run if no actual command is specified.

Data module

  • In context by default
  • Default command is 'varedit' if in context

Global commands:

varedit - (none), / - Sets an existing variable. If does not exist then fails.
var - var, /var - Creates a new variable only. If already exists, then does not change value.
set - set, /set - Creates or sets a variable. Works whether already exists or not.
alias - alias, /alias - New named script. Will change existing alias if already created.
bind - bind, /bind - Key to script. Map a key to a script block.
echo - echo, /echo - Write text to log only. Print text to current console but not the file.
print - print, /print - Write text to log and file. Print text to current console and to file.
context - context, /context - Change context. Change current console context to another known context.
run - run, /run - Load and run script file. Run a named script file. Name must include extension.

Global vars:

lib_path - './lib/' - Path for native 'world' modules.
base_path - './data/' - Path for content and assets.
module - 'game' - Base name for 'world' module, without platform postfix.
GameDll - (none) - Full path for 'world' module, './lib/gamex86.dll'.
s_use_ai - '1.0' - If world 'AI' processing is enabled.
map - 'maps/base1.bsp' - Full path for default content module.
startup - (none) - Full path of initial startup script.

Assignments:

Explicit context name is 'global'
Default reachable contexts: 'client'
Optional reachable contexts: 'lua'
Default log assignment is 'log'
Initial console assignment is 'console'

Lua context

Free standing Lua context in the Data module as a script interface to the main Lua runtime.

Lua context commands:
