Solved "Unexpected exception while parsing console command"

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        Player p = (Player) sender;
        if(sender instanceof Player){
            if(p.hasPermission("raza.neko")) {
                ponerSombrero(p);   
            }
        }else{
            sender.sendMessage("You cant do this command in the console");
        }
        return true;
    }

Hello ^^ , so... I'am doing a little plugin and in this case, just I want to get a message of the console "you cant do this command in the console" when I try to do a command, Its easy. I tried to do all , but I have this issue always . (I have the command registered in onEnable).

Code:

>neko

ClassCastException. Can you imagine what that is? You cast the sender to Player right in the beginning of onCommand without testing if it is a player.

Btw what does you sombrero look like you give the player?

 

I dont really understand you. In the second line I define the sender like a player. So.... if the sender is not a player, send a message by console with that message right? , sorry, Im noobie jajaja

 

Firsr you have to check if sender is a player:

Code:

if(sender instanceof Player){

Then you can cast him/her to player:

Code:

Player rfp = (Player) sender;

Otherwise you will get an Exception if somebody tries to call the command from console = not a Player

 

ah! , If i put first "Player p = (Player) sender;" I define before of the sentence , the sender like the player, okok , I understand and now works , thank you!

 

good luck continiuing
