Thread Condition:

Non open for farther replies.

1. I'm working on a kit plugin and I'm trying to organize it and add the commands dissever classes, but when I attempt and run the command, it doesn't piece of work and I get an error saying that its "Zippo".

   Main Class:

   packet com.ragecraft.pvpkit;   import java.io.IOException; import coffee.util.logging.Logger;   import org.bukkit.Bukkit; import org.bukkit.configuration.file.FileConfiguration; import org.bukkit.event.Listener; import org.bukkit.plugin.java.JavaPlugin;   import com.ragecraft.pvpkit.Kits; public grade Principal extends JavaPlugin implements Listener {         Logger logger = Logger.getLogger("Minecraft");         public void onEnable() {         logger.info("[PvpKits] Past Epicballzy!");         Bukkit.getServer().getPluginManager().registerEvents(new EventHandlers(), this);         getCommand("pvpkit").setExecutor(new Kits());         try {             saveConfig();             setupConfig(getConfig());             saveConfig();         } catch(Exception eastward) {             eastward.printStackTrace();         }     }       private void setupConfig(FileConfiguration config) throws IOException {     if(getDataFolder().exists()) {         config.gear up("kits.Mage.items" , "267 1, 364 32, 302 ane, 303 one, 304 1, 305 ane");         config.set("kits.Archer.items" , "261 1, 262 64, 364 32, 298 ane, 299 1, 300 1, 301 i");         config.set("kits.Poorman.items" , "272 i, 364 32, 298 1, 299 one, 300 i, 301 1");         config.prepare("kits.Axehead.items" , "279 i, 260 64, 298 ane, 299 1, 300 i, 301 1");         config.set("kits.Fisherman.items" , "346 1, 268 1, 298 one, 299 1, 300 i, 301 1");                 config.set("kits.names", "Mage,Archer,PoorMan,AxeHead,FisherMan");         }     } }

   I feel like I'one thousand making a simple mistake that I cannot figure out. Whatsoever help is appreciated!

3. 
   The plugin.yml should be correct.
   

   proper noun: PvpKits main: com.ragecraft.pvpkit.Principal version: 3.0 description: KitPvp! Author: Epicballzy   commands:   pvpkit:     clarification: List of Available Kits.

   It's the same as it was earlier I decided to motion the commands over to dissimilar classes.

4. Also, umm, why does Kits extend Chief?

   Whoops, silly owl. ;P
   The fault is an IllegalArgumentException, apparently on line 37. What'south line 37?

   You're missing your brackets { } in some places buddy.

   EDIT:

   I believe this should work, if you register your commands in OnEnable

                             
                               
                                 
                                   getCommand(                                "pvpkit"                                ).setExecutor                                (                                new                                Kits(                                this                                )                                )                                ;                              
                               
                             
                           

   Your plugin.yml

   proper noun: PvpKits main: com.ragecraft.pvpkit.Chief version: 3.0 commands:   pvpkit:       description: Put curt description here       usage: /<command>       permission: <plugin name>.permission_node       permission-message: Yous don't have <permission>

7. I don't think I'm missing whatsoever brackets.. The command piece of work perfectly without information technology beingness in a separate class.

8. Epicballzy
   Now Im not sure what youre asking then.
   Line 37 is missing a opening bracket for sure.
   You need { after for and if statement as far as I know.

9. Adriani6 Not necessarily. If only a single statement is associated with an if/for/while statement, and so the braces do non have to be included.

   For example

   if(player.getName().equals("SnipsRevival"))     histrion.sendMessage("You are merely precious!")

   is valid despite not having opening braces.
