Java plugin in two Class.

I want create small plugin.
It`s my main:

Code:java

package blockspawn;
 
import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;
 
 
 
public class Main extends JavaPlugin {
 
    ClassBlock respawn;
 
    public void onEnable() {
        Bukkit.getServer().getPluginManager().registerEvents(this, ClassBlock());
        respawn = new ClassBlock(this);
    }
}

It`s my other Class:

Code:java

package blockspawn;
 
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scheduler.BukkitRunnable;
 
public class ClassBlock extends JavaPlugin implements Listener{
 
    Main main;
    public ClassBlock(Main main) {
        this.main = main;
    }
 
    @EventHandler
    public void onBlockBreak(BlockBreakEvent event){
            final Block origin = event.getBlock();
            @SuppressWarnings("deprecation")
            final int type = origin.getTypeId();
            if (type == 15) {
                event.setCancelled(true);
                origin.setType(Material.COBBLESTONE);
                Player p = event.getPlayer();
                PlayerInventory pi = p.getInventory();
                ItemStack IronOre = new ItemStack(Material.IRON_ORE, 1);
                pi.addItem(IronOre);
                new BukkitRunnable() {
                    public void run() {
                      origin.setType(Material.IRON_ORE);
                    }
                    }.runTaskLater(this, 300);
                }
    }
}

If you do not import JavaPlugin Event will not work.
And if you import JavaPlugin Event does not register.
What to do?

 

The solution is simple

Add this to your constructor in the ClassBlock class

Code:java

 Main main;
public ClassBlock(Main main) {
this.main = main;
Bukkit.getPluginManager().registerEvents(this, main);
}

And remove that extends JavaPlugin

Code:java

 public class ClassBlock implements Listener {

And in your onEnable you should change this:

Code:java

 public void onEnable() {
respawn = new ClassBlock(this);
}

By the way this is really basic stuff about events

 

Ewwwwwwwww, why the hell are you doing that, just remove the ClassBlock(Main main) from the classblock class then remove te extends javaplugin and simply register it by doing:

PluginManager.registerEvents(this, new ClassBlock());

 

DevRosemberg So that he can access his main class from his listener.

 

Tirelessly what?

 

DevRosemberg wow... http://en.wikipedia.org/wiki/Object-oriented_programming

 

Tirelessly just saying but nt everything has to have OOP.

 

Java by design to be an Object-Oriented language. If you are doing almost anything in Java you are in OOP land.

Heres another method that I use:
1. Add a line to your Main class that is:

Code:java

Main plugin;

2. Now add this to your onEnable. This will define the variable we just created:

Code:java

plugin = this;

3. Now add this to your onDisable:

Code:java

plugin = null;

4. Add this method to the class. The name of it doesn't matter, you can use getInstance, getPlugin, or anything!

Code:java

public static Main getPlugin() {
return plugin;
}

5. Now you can reference the main class by doing this:

Code:java

Main.getPlugin()
// If you want to get the config
Main.getPlugin().getConfig()

Then we're done! You can now use methods from JavaPlugin in other classes!

Don't forget to set that instance to null when the server disables
