Responses are a feature similar to voice commands, where your character may deliver a line of speech when a response rule is met. The difference is that while a voice command can be initiated with the press of a button by the player, these speech lines only play in reaction to the player completing a specific task, such as taking Intelligence, killing several opponents in a row, destroying an Engineer's buildings, participating in a duel, or getting a Domination on a particular class. Even when these rules are met, some of the speech files play only very rarely. Some response rules are common to all classes, while others may be specific to that class.
The Administrator also possesses responses that play when certain conditions are met, some of which occur 100% of the time (such as "You've failed!" on a match loss).
- Scout responses

Response rule scripts
The scripts that control the responses are located inside the
.vpk, located inside
Steam\steamapps\Common\Team Fortress 2\tf, along with the other Team Fortress
.vtf files. This file can be inspected with a tool such as GCFScape. Once you've got the content file open, the response rule scripts are located in
The main script file is
response_rules.txt. This file contains a description of the script language used by the responses, as well as definitions for most of the criteria used in the scripts. Additionally, there is one script file for each class. These files contain most of the class specific response rules and voice commands. Finally,
tf.txt contains taunt rules for each class, as well as a few miscellaneous class-specific rules (such as rules to cause the Heavy to emote after firing his Minigun for a while).
The result of a scripted action is usually a scene. A scene defines what is said as well as the expression on the character's face when it is said. Scenes are defined in individual .vcd files, which can be found packaged in the
.vtf, located in
There is one further level of abstraction between the response rule scripts and the actual sound spoken by the character. Scene files refer to a specific speech event, such as "
Demoman.AutoCappedControlPoint03". These events, found in the
tf2_misc_dir are defined in
root\scripts\game_sounds_vo.txt and they refer to actual
.wav files packaged in the
.vpk (such as, for instance,
demoman_autocappedcontrolpoint03.wav). The wave files are located in the
In general, there is a direct mapping between the name of the scene (
.vcd) file referred to in the response rules scripts and the name of the wave (
.wav) file spoken by the character.
