In City of Heroes and City of Villains, there are a number of commands that can be typed on the chat command line to execute various functions. These are known as slash commands, because they begin with a slash (/). Slash commands often have underscores within the name to improve legibility, but they are not needed to actually take effect, i.e. /PowExec_Name, /Pow_Exec_Name, /P_o_w_E_x_e_c_n_a_m_e all perform the same way. Almost every action taken in the game is a slash command bound to a key. The number 1 is "pow_exec_slot 1", which executes the power in slot 1 of your power tray. Some slash commands, such as the movement commands, should not be called from the chatbox without taking care and knowing what will occur. See List of Slash Commands for a list of known slash commands; see also Category:Slash Commands.
Multiple commands may be strung together for simultaneous execution using the '$$' operator. For example, the following command will cause a character to say "Ready!" and perform the "thumbsup" emote at the same time.
Note that when concatenating two or more commands, the slash is used on only the first command.
Substitution strings, also referred to as variables, allow you to create commands that will display the same basic behavior each time they are used, but will vary slightly depending on certain variable conditions such as your current character or your currently selected target. When a variable is used the appropriate information referring to your target or character is substituted for the variable before it is sent to the appropriate communication channel. Several pre-defined substitution strings exist and are denoted by a single '$' prefix:
- $archetype - the archetype of your character
- $battlecry - your character's battlecry, as entered on your character ID screen
- $level - your character's current level
- $name - your character's name
- $primary - your primary power set
- $secondary - your secondary power set
- $origin - your character's origin
- $target - your currently selected target's name
- $side - displays "Hero" or "Villain" depending on your character's current content flag (see Variables page for more details)
- $loc - your current coordinates as a clickable thumbtack link
For example, if a level 12 natural-origin scrapper named Captain Obvious were to target a Behemoth Overlord, the following command would cause him to say "I, Captain Obvious, a level 12 natural scrapper, challenge you, Behemoth Overlord, to a battle to the death!" in his currently selected chat channel.
- /say "I, $name, a level $level $origin $archetype, challenge you, $target, to a battle to the death!"
The same command, executed by a level 42 magic-origin brute named Mauler who is targeting Arbiter Howe would cause the character to say, "I, Mauler, a level 42 magic brute, challenge you, Arbiter Howe, to a battle to the death!"
