Here is the only class in the plugin

public class MainClass extends JavaPlugin
{
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[]args)
    {
        if(label.equalsIgnoreCase("ablaze"))
        {
            if(sender instanceof Player)
            {
                Player player=(Player)sender;
                if(args.length==0)
                {
                    player.setFireTicks(400);
                }
                else if(args.length>0 && args.length<2)
                {
                    loop:
                    for(Player currentPlayer: Bukkit.getOnlinePlayers())
                    {
                        if(player.getName().equalsIgnoreCase(args[0]))
                        {
                            currentPlayer.setFireTicks(400);
                            currentPlayer.sendMessage("Probably want some ice for that...");
                            break loop;
                        }
                    }
                }//end bracket for arg# check
            }//end bracket for if Player sent

                        {
                            currentPlayer.setFireTicks(400);
                            currentPlayer.sendMessage("Probably want some ice for that...");
                            break loop;
                        }
                    }
            }//end of if commandblock sent
        }
        return true;
    }
}

Does anyone know what is going on here? It's likely a really dumb mistake on my part, but I'm somewhat new to java programming, and I do not understand what that error exactly means.
Sorry if my incompetence is aggravating.

 

On line 43, you're using a variable called "player", but no such variable exists in that context. I think you meant "currentPlayer". (How on earth did you get that to compile?)

 

where is your onEnable and onDisable methods?

Code:java

@Override
public void onEnable() {
    getCommand("ablaze").setExecuter(this, this);
}
 
@Override
public void onDisable() {
 
}

also add implements CommandExecuter after extends JavaPlugin.

The main class is its own executor by default.

 

lol

I know Guess im just used to using seperate classes for each of my commands.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

Only in the case of using the inherited command method, however.

Tecno_Wizard
One of the first things you do is cast Player to sender. How can a command block execute a command if you are automatically defining the sender as a player? Player =/= Command Block. I believe it is CommandBlockSender, not sure though. Never mind.

 

It doesn't need to 'implement CommandExecutor' if it's in his main class..

 

What is the 'loop:' line supposed to be?

 

adam753
I just now caught that. And I agree, how on earth did eclipse miss that?
Edit: went and changed one letter and put it back, THEN eclipse registered it as a problem. Pff, computers...
