[Tutorial] How to make a Simple Basic Bukkit Plugin

yup

u want the network id and password?

Private Message me your info

I'm sorry for my extreme noobiness but how do I pm you on this site?

Click my name here and Click Start Conversation

thanks for being so helpful emericask before, so can you help me again by saying what would you do if you wanted to say something to the whole server. A bit like [BROADCAST] and [SERVER] except custom text like [ORANOBROADCAST]? So you could have a custom tag that goes to everyone on the server, and then some text afterwards like, [ORANOBROADCAST] Everyone Get in side your homes!

and of course this could be activated via a command?

Make a variable for Server
Server server = sender.getServer();


And then look in the API! It has broadcast

thanks, also my plugin has the same problem as before you helped me!

Just remember what I showed you, use the same method.

I'm new to making plugins so to get at least something to work I copied your whole code from the tutorial, but I'm very confused because it doesn't work. Red and yellow underlines everywhere, what could the problem be? Thanks!

Chat color needs to be imported and with capital C (ChatColor) and yellow is because the new Bukkit doesn't use the methods for old events anymore

Im not getting the Events When you type Event.type.?
Help?

Im having the same problems as bierbuikje i believe.

Any help is appreciated as i'm doing this for a project in school.

Here is my code

Main.java

Code:

package me.MyPlugin.MyPlugin;

import org.bukkit.event.Event;
import org.bukkit.event.EventPriority;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.plugin.PluginManager;

public class Main extends JavaPlugin{
    
    private final BL BlockListener = new BL();
    
    @Override
    public void onDisable()
    {
        System.out.println("My plugin is disabled.");
    }
    
    @Override
    public void onEnable()
    {
        PluginManager pm = getServer().getPluginManager();
        pm.registerEvent(Event.Type.BLOCK_BREAK, BlockListener, EventPriority.NORMAL, this);
        System.out.println("My plugin is enabled.");
    }


}

BL.java

Code:

package me.MyPlugin.MyPlugin;


import org.bukkit.ChatColor;
import org.bukkit.Server;
import org.bukkit.entity.Player;
import org.bukkit.event.block.BlockListener;
import org.bukkit.event.block.BlockBreakEvent;

public class BL extends BlockListener
{
    public void onBlockBreak(BlockBreakEvent event)
    {
        Player p = event.getPlayer();
        Server s = p.getServer();
        String playername = p.getName();
        ChatColor blue = ChatColor.BLUE;
        s.broadcastMessage(blue + playername + "Has broke a block!");
    }
}

Also here is my plugin.yml

Code:

name: MyPlugin
version: 0.1
main: me.MyPlugin.MyPlugin.Main

And these are the errors i'm receiving when trying to run the plugin.

Code:

Ok so ive narrowed it down somewhat. Basically i think my problems are:
The import org.bukkit.event.block.BlockListener cannot be resolved and BlockListener cannot be resolved to a type.

Nice nice

@emericask8ur

I did watched whole your video. Thanks for making this tutorial.
I wanted to make something simple just to get me started with writing plugins for minecraft on eclipse.
And really everything is going just great only minecraft is not cooperating with me or other way around.

I have this error on start from console.

This is my project

This tut is very outdated. Bukkit has new events, new methods, etc. I will create a new video soon.

Would be great. I just need to figure out what craftbukkit expects from me. Java as I see it is very similar to C and C++ so I should not have problem with it

yes that would be great

Guys new video above!

Where do I get that thing you call Eclipse?

Google it >.>

Thanks, it works!
But i want to do it in other way.. I want this: When player breaks diamond/emerald/gold ore admins got a message : 'playername' breaked 'orename'. Maybe you can help me to do this? I tried to rename OnBlockPlace to OnBlockBreak but it doesn't work
