Code:

package me.jacklin213.basic;
 
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.BlockPlaceEvent;
 
public class BasicBlockListener implements Listener {
    public static Basic plugin;
    public BasicBlockListener(Basic instance) {
        plugin = instance;
    }
 
    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        Block block = event.getBlockPlaced();
        if (block.getType() == Material.TORCH) {
            player.sendMessage("You have placed a torch!");
        if (block.getType() == Material.DIRT) {
            player.sendMessage("You have placed dirt!");
        if (block.getType() == Material.LAVA) {
            player.sendMessage("BEWARE no grefing with the lava!");
        }
        }
    }
}
}

it only says something when i place dirt but if i put torch to the top like this

Code:

package me.jacklin213.basic;
 
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.BlockPlaceEvent;
 
public class BasicBlockListener implements Listener {
    public static Basic plugin;
    public BasicBlockListener(Basic instance) {
        plugin = instance;
    }
 
    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        Block block = event.getBlockPlaced();
        if (block.getType() == Material.DIRT) {
            player.sendMessage("You have placed dirt!");
        if (block.getType() == Material.TORCH) {
            player.sendMessage("You have placed a torch!");
        if (block.getType() == Material.LAVA) {
            player.sendMessage("BEWARE no grefing with the lava!");
        }
        }
    }
}
}

it only sends a message when i place torch. PLZ help me

Code:

        if (block.getType() == Material.DIRT) {
            player.sendMessage("You have placed dirt!");
            if (block.getType() == Material.TORCH) {
                player.sendMessage("You have placed a torch!");
                if (block.getType() == Material.LAVA) {
                    player.sendMessage("BEWARE no grefing with the lava!");
                }
             }
        }

That's your code, properly indented. This isn't Python.The { brace signifies that the following code is inside the if statement, and } signifies that the code is no longer in the if statement.

Code:

        if (block.getType() == Material.DIRT) {
            player.sendMessage("You have placed dirt!");
        }
        if (block.getType() == Material.TORCH) {
            player.sendMessage("You have placed a torch!");
        }
        if (block.getType() == Material.LAVA) {
            player.sendMessage("BEWARE no grefing with the lava!");
        }

Is probably what you meant.

@jacklin213
Also, the event won't detect Lava placement because players are using a bukkit to place the lava. That should be handled in a BucketEmptyEvent instead.

kk ty @zhuowei it works ty @r0306 how would i do that?
another question is when i active it by doing /b it would say

Basic enabled (plugin name)
b

y does it say b under it ??

The /b displays because the plugin returned false after processing the command, which means "The command didn't work, show the help file".

Code:

public void onCommand(...stuff
   if (label.equals("b")){
       //do stuff
       return true; //Successfully executed
   }
   return false; //unsuccessfully executed; show the player the help.
}

but the command did work ??

Code:

public void onEmpty(PlayerBucketEmptyEvent event) {
  Player player = event.getPlayer();
  if (event.getBucket() = Material.LAVA_BUCKET) {
     player.sendMessage("BEWARE no grefing with the lava!");
  }
}

@r0306 u didnt make bucket a variable so it isnt working
how do i fix that?

Np.

You don't need a variable. What part of the code is not working?

Code:

public void onEmpty(PlayerBucketEmptyEvent event) {
  Player player = event.getPlayer();
  if ("event.getBucket"() = Material.LAVA_BUCKET) {
    player.sendMessage("BEWARE no grefing with the lava!");
  }
}

i put in quote marks

@jacklin213
Oh. I used the wrong operator. Use "==" instead of "=".

Code:

if (event.getBucket() == Material.LAVA_BUCKET) {

@r0306 what do i put if i wanted it to warn me when i break a block eg)leaves

Do you have any experience with java?

er kinda
