Parameters
Parameter
Type
Notes
Chat Ver
command
String
The command that was issued.
You can create a single handler function and use it as the handler for multiple chat commands, switching internally on the command name.
0.1
player
Number
The ID of the player that issued the command.
This is particularly useful if you want to start a chat conversation with that player in response to the command they just issued.
0.1
message
Array of String
An array containing each word in the player's message.
The string at message[0] will always be the command name (same as command parameter).
The conversation object associated with 'player' – see Conversation Mode for details.
Note: If your command handler function is invoked, then obviously there isn't an active conversation with that player. The conversation object is provided in case you want to add some data to it and start a new conversation as a result of the command that was just invoked.

Example
Single command, with different output based on second keyword
var helpHandler = function helpHandler(command, player, message, cdo) {
// command == message[0] == "help"
// message[1] == second keyword (eg. 'foo' if user sent '.help foo')
switch (message[1]) {
case "foo": return "some help for foo";
case "bar": return "some help for bar";
default : return "Type '.help <whatever>' where <whatever> can be either 'foo' or 'bar'";
}
}
chat.on("help", helpHandler);
/* user can now send commands such as:
.help = Type '.help <whatever>' where <whatever> can be either 'foo' or 'bar'
.help foo = some help for foo
.help bar = some help for bar
*/
Single handler for multiple commands
var multiHandler = function multiHandler(command) {
switch (command) {
case "foo": return "command: foo";
case "bar": return "command: bar";
default : return "unknown command: "+command;
}
}
chat.on("foo", multiHnadler); // .foo = command: foo
chat.on("bar", multiHandler); // .bar = command: bar
chat.on("moo", multiHandler); // .moo = unknown command: moo
