Adding a poison effect of a certain item.

I´m not very good with making plugins but I really want to learn it. What i have right now: /dagger and you will get a Flint in your hand called AssassinDagger with nice colors and multiple lines. But I need it so that when I hit a mob or player, they will get poisoned for a few seconds. How do I do this?

 

@HiDPiD Listen for a EntityDamageByEntityEvent, check if the damager is a player and if so are they holding the assassin's dagger, and then apply the poison effect to the damaged entity.

 

Okay, but how do I do that? Like I said, im not that good ^^

 

@HiDPiD Apologies. I thought you were referring to skill level, not experience.

Code:

public class ExamplePlugin extends JavaPlugin implements Listener {
  @Override
  public void onEnable() {
    getServer().getPluginManager().registerEvents(this, this);
  }
  @EventHandler
  public void onDamage(EntityDamageByEntityEvent e) {
    if (e.getDamager().getType().equals(EntityType.PLAYER)) {
      Player p = (Player) e.getDamager();
      ItemStack stack = p.getItemInHand();
      if (stack != null && stack.getType().equals(Material.FLINT)) {
        ItemMeta meta = stack.getItemMeta();
        if (meta.hasDisplayName() && meta.getDisplayName().equals(/*insert name of your item here*/)) {
          LivingEntity entity = (LivingEntity) e.getEntity();
          entity.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 60, 2));
        }
      }
    }
  }
}

 

Thanks for the reply, but the poison effect doesn't work. What have I done wrong?

@pie_flavor Please don't SpoonFeed. He won't learn anything from this by copying the code.

 

@HiDPiD You have replaced the '60' with '3'. I too meant 3 seconds, but 60 is the number of ticks, which is what the int measures.
@JoaoBM Funny, it failed because it wasn't copied enough.

 

@pie_flavor No, it failed because you did not explain what you were doing so he didn't understand it and made it wrong.

 

No one learns anything by spoonfeeding them code. That's why I miss the voting from stackoverflow. Some comments cpuld be easily voted down, like spoonfeeding.

 

Even when I replaced it back to 60, it doesn't work

Oh, nevermind, it does work. Only not on hostile mobs! Thanks!
