From Team Fortress Wiki
Scripting is the use of configuration files (.cfg) to create new keybinds and aliases automating complex behaviors and console command sequences. Scripting is built into Team Fortress 2 and is not banned by VAC (Valve Anti Cheat). Uses of scripting vary from simply binding a key to a command to self-referential loops and nested aliases that redefine one another. Any functionality that can be created with scripting can also be accomplished without, however scripting will allow these functionalities to be used even in fast-paced battle.
Dedicated Scripting Files
Team Fortress 2 automatically reads several game files and executes any scripts within them. Here is the list of those files:
- config.cfg - This is the default configuration file which is edited to reflect any in-game changes to keybinds or video settings. It is safe to edit this file, but it will change to reflect any modified keybinds on startup. This config will run every time the game starts up, before any other config.
- config_default.cfg - This contains a basic set of keybinds, and will be executed as a backup if config.cfg is not present.
- autoexec.cfg - This is the default config file for executing custom keybinds and aliases. This config will run every time the game starts up, after config.cfg.
- Scout.cfg, Soldier.cfg, Pyro.cfg, etc. - Each class has a config file which automatically runs whenever you switch to that class. Note that any settings set in one classes config file will be retained when switching classes unless explicitly rebound.
The following is a list of commands which have no use apart from scripting; they do not influence gameplay directly.
The simplest command is the bind command. It will cause a certain key to execute a certain action, whether that action is a setting, a command, or a script.
bind [KEY] [COMMAND]
Quotes can be optionally placed around the key or the command.
bind [KEY] "[COMMAND 1]; [COMMAND 2]; [COMMAND 3]"
Quotes can be optionally placed around the key, but must be present around the commands.
Commands come in two forms:
bind "e" "Voicemenu 0 0"
This bind will make the player call for a Medic when they press .
bind "w" "+forward"
This bind will make the player move forward while they have held down.
This command allows a setting to be toggled between two or more values.
toggle "sv_cheats 0 1"
This works identically to toggle, but binds it to a key.
bindtoggle o "sv_cheats 0 1"
This allows for variables to be increased or decreased repeatedly by a set amount.
bind MWHEELUP "incrementvar fov_desired 75 90 1"
bind MWHEELDOWN "incrementvar fov_desired 75 90 -1"
This will cause the field of view to increase when scrolling up, and to decrease when scrolling down.
Note: Incrementvar will cause the value to wrap around if it gets too large or too small. In this example, once the field of view hits 90, it will drop down to 75, and vice-versa.
An alias allows multiple commands to be referenced by a single command. This is effectively shorthand, and it is most useful when a series of commands need to be called multiple times.
Note: Alias names cannot contain spaces. They may contain underscores, numbers, and symbols. Alias names are case-sensitive.
alias Call_For_Medic "Voicemenu 0 0"
bind "e" "Call_For_Medic"
This script functions the same with a simple bind, meaning that when the player presses , they will call for a Medic.
This command will execute another file. This means that complex scripts can be stored in other files, so as not to clutter up more general files.
This script will execute the player's autoexec script.
This command will cause text to be printed to console. This is very useful for debugging.
echo Scripting is; echo very useful.
This will print out
Scripting isvery useful. Spaces are only parsed if they are between words, or if the echoed text is between quotes, as in the next example.
echo " Scripting is very useful. "
The extra spaces will be printed out, since the sentence is denoted by quotation marks.
Note: It is not possible to print out the " or ; characters, as their meaning will be misinterpreted.
This command will make the game wait a given number of frames before executing the next command.
Note: The amount of real time this corresponds to depends on the server's tickrate.
Warning: Wait commands are disabled on certain servers. This will cause certain scripts to fail, and may (in semi-rare cases) cause the game to crash.
echo Why did the chicken cross the road?; wait 66; echo To get to the other side!"
This script will wait 66 frames (1 second on most servers) before printing the punchline.

Advanced Scripting Techniques
It is possible to bind a key to toggle a command which would otherwise be a press and hold command.
bind w toggle
alias toggle "enable"
alias enable "alias toggle disable; +forward"
alias disable "alias toggle enable; -forward"
This script will cause a press of to keep the player moving forward until is pressed again.
It is possible to create a script where pressing one button while another is held down will change the action of the first button.
bind e call
alias call Call_For_Medic
alias Call_For_Medic "Voicemenu 0 0"
alias Call_For_Ubercharge "Voicemenu 1 6"
At this point, the script will mean that every time is pressed, the player will call for a Medic. It also has an unused alias to call for an Ubercharge.
bind shift +toggleState
alias +toggleState "alias call Call_For_Ubercharge"
alias -toggleState "alias call Call_For_Medic
Now, pressing will redirect
call to ask for an ubercharge. Releasing will make
call point back at a Medic call.
When + is pressed, the player will call for an Ubercharge, rather than for a Medic.
wait command is integral to some scripts, it may be necessary to test to see if a server has disabled the command.
alias waitTester "alias waitTest waitPositive; wait; waitTest"
alias wait "alias waitTest waitNegative"
alias waitPositive "echo Wait is enabled on this server.; exec waitPositive.cfg"
alias waitNegative "echo Wait is DISABLED on this server!; exec waitNegative.cfg"
This script relies on the fact that if the wait command is disabled on a server, the alias named
wait can be defined by the user. Thus, the script creates an alias named
waitTest which by default points to
waitPositive, but if
wait is not allowed (and can thus be defined by the user), will be redirected to
Warning: Loops which run without a wait command will cause the TF2 client to hang. It is highly suggested to run a script only after a wait testing script.
It is generally considered bad form to have one alias point to itself, as this loop cannot be broken out of and the reset. Therefore, looping scripts tend to include two parts to the loop: The part that waits, and the part that loops.
alias loop "+taunt; wait 132; redirect"
alias redirect loop
bind g "redirect"
bind o "alias redirect break"
alias break "alias redirect loop"
This script will start looping once is pressed. It will then taunt every 132 frames (2 seconds on most servers). Pressing would cause the next iteration of the loop to break out. The
break alias will then reset the loop, so that next time it is called it will loop again.
There are several notable scripts that have affected gameplay. Some of these are patched out, while others remain functional.
Originally, the Pistol could be fired almost as fast as the human hand could press a key. Scripts were created to simulate this rapid pressing by holding down a single key.
August 13, 2009 Patch: The Pistol now fires at a fixed rate, not based on the speed at which you press the firing button.
Chargin' Targe turn scripts
Originally, the keyboard commands to turn your viewpoint left and right were not treated the same as the mouse commands. The Chargin' Targe was the first weapon to create a restriction on how quickly you could turn your viewpoint, therefore Valve put a limit on mouse turn-speed, yet forgot to apply the same restriction to the keyboard command that resulted in the same action. Scripts were created to rebind the turning controls when a player charged, circumventing this restriction.
June 23, 2011 Patch: Fixed an exploit with the Chargin' Targe that allowed greater turning control than intended.
However, there is still no cap on turn speed when using a gamepad's analog sticks.
Air crouching scripts
Originally, you could crouch as many times as you liked in a single jump. By binding a script to crouch and uncrouch as rapidly as possible, you could exploit the engine and make it difficult to properly register shots on jumping targets.
March 6, 2009 Patch: You can now duck twice in the air.
Gloves of Running Urgently Scripts
The Gloves of Running Urgently used to drain 6 health per second while active. However, jumping preserved the speed bonus granted by this weapon and did not require the weapon to be active. Simple scripting allowed for the player to quickly switch to the gloves, jump, and then switch away.
Weapon Hiding Scripts
There are a large number of scripts which toggle the weapon display option depending on which weapon slot is selected for a class. Players often make their guns invisible to clear up the screen, but make items like melee weapons, PDAs, watches, and so forth visible because these models indicate important information. For example, the Spy relies heavily on his visible model to determine when he is cloaked, when his Cloak is disturbed, and when the Dead Ringer activates. Other classes use the melee animations to judge when their attacks will hit.
Sentry Jumping Scripts
Since the Engineer Update, Engineers have been able to pack up and carry their Sentry Guns. Simultaneously introduced in the update, the Wrangler allows Engineers to Sentry jump with their Sentry rockets. With extremely fast inputs, it was discovered that a player could Sentry jump and successfully pack up their Sentry before they were launched away.
While a human can repeat this feat, it is difficult. Some players made scripts which could reliably execute the commands in the right order at the right speed allowing them to make a Sentry jump while carrying their Sentry every time.
Note: The Rescue Ranger can circumvent this necessity, as it can pick up buildings at range for 130 metal.
Since it can be troublesome to destroy then rebuild a Combat Mini-Sentry in the heat of battle through the PDA, some players have scripted the destruction and rebuilding of their Combat Mini-Sentry with the click of one or two mouse buttons. Such a script is especially useful when using the Frontier Justice, as the player gains practically instant access to revenge crits when needed.
Sensitivity and Control scripts
Some players prefer different mouse sensitivities and control schemes for some classes. (For example, changing from the Medic, which doesn't require fine aiming, to the Sniper, which encourages low sensitivity for precise aiming so that a hand twitching inadvertently won't ruin a player's aim too much) These scripts alter control schemes and mouse settings on a per class, or even per weapon, basis.
Charge Dash Scripts
Since timing a charge and jump can be difficult, some players may use a quick script that binds the two actions to a button so that the charge dash will cover the maximum amount of distance possible. The player is still required to swing their melee weapon normally to end the charge though.
Many players find it difficult to scope in and fire straight after to get a quick headshot. There are scripts that will zoom in and fire just by clicking one mouse button. This does require players to aim outside of the scope, though.
Rocket Jump Scripts
In order to Rocket Jump to a maximum height or distance, it is required that the player jumps, crouches, and fires their rocket at roughly the same time. This can be easily scripted to occur with the press of a button.
