Dev Commands

First of all, make sure that you have the BedwarsAddon object.
Click here to get to the documentation for that.
Adding commands isn't much harder than creating the BedwarsAddon.
Simply create a new BedwarsAddonCommand (Example:

BedwarsAddonCommand cmd = new BedwarsAddonCommand("testcommand" /* command */, "<arg1> [arg2] [arg3]" /* usage */){
  public void onWrite(String[] args){
     // do something
  }
};

) And register the command using the registerCommand method in the BedwarsAddon command (Example:

bedwarsAddon.registerCommand(cmd);

).
