yea now i dont have error but i cant register command http://postimg.org/image/tltypsxkh/

[Tryskell]

Is that that hard to see how others usercommands are written ?

public class ChannelDelete implements IUserCommandHandler

meaning you must have in your children class

public boolean useUserCommand(int id, L2PcInstance activeChar);

public int[] getUserCommandList();

methods otherwise it won't work.

public boolean useuserCommand(String command, L2PcInstance activeChar, String target)

!=

public boolean useUserCommand(int id, L2PcInstance activeChar)
