The following are basic usage examples for commands, the command options and the CommandEvent. Please note that, in each of these examples, the value returned from commandEvent.getSender() is always a player.
Command Options
This example contains a command in which all command option specifications have been filled.
This example contains a command that requires arguments to be specified from the player. The list of arguments is returned when calling commandEvent.getArgs() and thus we can use [1] to get the first argument that was specified.
plugin.addCommand({name="command", description="Execute the command /command", usage="/command <message>", minArgs=1},function(commandEvent)
commandEvent.getSender():sendMessage("You executed /".. commandEvent.getCommand().." with the message: ".. commandEvent.getArgs()[1])
