I may be stupid but how do I make it so my plugin won't Trigger when somneone is using anothetr command?

King Nothing · Dec 10th 2017

every time i go to write a plugin I give up because of the commands.
let's say someone uses mino's mail plugin and just types "/mail" my plugin gives a bunch of red text (yes it is mine that is giving it)

Minotorious · Dec 10th 2017

Could you post the red text? or the log file which will contain it and would make reading it a lot easier for me?

In general if you follow the command plugin example from red51 your plugins will not have any problems colliding with other plugins (that is unless both plugins use the exact same command).

Java

@EventMethod
    public void onCommand(PlayerCommandEvent event){
        Player player = event.getPlayer();
        String command = event.getCommand();
        //split the command
        String[] cmd = command.split(" ");
        //check the command, example: mail command
        if(cmd[0].equals("/mail")){
            //check if player provided appropriate input
            if(cmd.length == 4){

it only does that when i issue a bad command.

Minotorious · Dec 10th 2017

well can I see either the error or the code snippet which causes the error or better both? Without more information I can't possibly guess where the issue might be

King Nothing · Dec 10th 2017

Code

public void onCommand(PlayerCommandEvent event){
        Player player = event.getPlayer();
        String command = event.getCommand();
        //split the command
        String[] cmd = command.split(" ");
        //check the command, example: teleport command
        if(cmd[0].equals("/tp")){
            //check if player provided coordinates
            if(cmd.length == 2){
           String place = command.substring(3);
                //teleport player

                //send message to player
                player.sendTextMessage("[#FFFF00]Teleported to"+place);
            }
            else{
                //inform player that he has to enter coordinates
                player.sendTextMessage("[#FF0000]You have to Tell me Where you want to go!");
                player.sendTextMessage("[#FF0000]USAGE: /tp 'BootyBay'");
            }

can you please highlight line number 56 for me to see which array is trying to access an incorrect index?

King Nothing · Dec 10th 2017

(56, now 54) else if(cmd[1].equals("/adminmessage")){ < i didn't give the WHOLE code, but that is what is giving me errors,

Code

else if(cmd[1].equals("/adminmessage")){
            if(cmd.length > 1){
                //get the rest of the message
                String message = command.substring(14);  //remove the first 14 characters
                //send to all admins, check all players if they are admins
                for(Player p : getServer().getAllPlayers()){
                    if(p.isAdmin()){
                        p.sendTextMessage("[#FF0000]" + player.getName() + ": " + message);
                    }
                }
            }
            else{
                //inform player that he has to provide a message
                player.sendTextMessage("[#FF0000]You have to provide a message");
                player.sendTextMessage("[#FF0000]USAGE /adminmessage message");
            }
        }
    }

do i need a "blank" command so it won't complain?

Minotorious · Dec 10th 2017

the second one should be an "else if(cmd[0].equals("/adminmessage")){" with a 0 again not a 1

yahwho · Dec 10th 2017

.equalsIgnoreCase()

People should use that more often ☺

King Nothing · Dec 10th 2017

thanks That [0] helped, I don' know why Red's has [1] and ill use ignorecase that should help, too.

yahgiggle · Dec 13th 2017

when using a command /thiscommand it always starts with 0 you only use 1 or 2 or 3 when the command is split into more than one Lets say words

like /this command = (cmd[0] = this) and (cmd[1] = command)
or /this command is sweet = (cmd[0] = this) and (cmd[1] = command) and (cmd[2] = is) and (cmd[3] = sweet)

so you can do things like

if cmd[0] = this and cmd[1] = command and cmd[3] = sweet then do this

King Nothing · Dec 13th 2017

Thank you. that cleared up the confusion. guess i didn';t know about combining commands. No more red errors, it feels like i kinda know what I'm doing now, LOL.. with your help from last time and I'm looking up how to do some stuff for the most part, the plugin is coming along.
might just make the quotes a separate plugin and upload it after its done,

sweet, yeah sometimes when someone tells you whats wrong with your code it does not help you learn why it did not work in the first place, all its done is fix the error but you learnt nothing and your just left confused because you had seen red51 use cmd[1], so that's why i did my reply, so you can learn and get better at coding, and now when you look back at reds code your see he was in fact right to use cmd[1] lol

Anyway good luck with your plugin, and now with your new knowledge your be able to open up a whole lot of new ideas with lots more problems to solve lol Coding why do we do it oO

@yahgiggle as a matter of fact I just checked red's code snippet and he actually has a mistake, that 1 should be a 0 in his code too.

See thread: Create a Plugin

in the last example after "Here is a more complex Plugin-class which listens for the PlayerCommandEvent (when a player enters a command) as well as the PlayerChatEvent (when a player writes a chat message):"

this line (No. 48): else if(cmd[1].equals("/adminmessage")){

should be: else if(cmd[0].equals("/adminmessage")){

I am sure he wrote that in a hurry without really testing it thus the error

Oh, that's true Sorry for the confusion, I've updated the post, thanks @Minotorious and @Captian_Cornball for pointing that out
