what on earth

why doesn't this work??

Code:

public class Core extends JavaPlugin implements Listener{
   
    public void onEnable(){
        getServer().getPluginManager().registerEvents(this, this);
        getLogger().info("odjawdawd");
    }

    @EventHandler
    public void onMove(PlayerMoveEvent e){
        Player p = e.getPlayer();
       
        if(p.getInventory().getItemInHand().equals(Material.STICK)){
            Block b = p.getLocation().getBlock();
           
            if(!(b.getRelative(BlockFace.DOWN).getType().equals(Material.TNT))){
                b.setType(Material.TNT);
                p.sendMessage(ChatColor.GREEN + "[Tnt] Placed block of tnt");
            }
        }
    }
}

 

First, I believe you need to override the onEnable and you also need to add onDisable and override that too.
Thats just from a quick look.

 

Again, don't expect us to magically know exactly what you're thinking. Doesn't work how? What is it supposed to do and what does it actually do?

EDIT: Another quick look and I see you are comparing an ItemStack with a Material. Those will never be equal and the condition is always false.

None of what you've mentioned will make a difference.

 

#getType == Material.STICK

 

add in an if statement to check if player.getItemInHand()!=null then do that toher stuff
