My code doesnt work

A little nooby of me, but this little bit of code doesnt work, help?

Code:java

@EventHandler
    public void onHit(EntityDamageByEntityEvent e) {
        Player dmgd = (Player) e.getEntity();
 
        if(e.getEntity() instanceof Player && e.getDamager() instanceof Arrow) {
          dmgd.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 1, 5));
      }
    }

 

You cast e.getEntity() before checking it.

 

I tried adding dmgd.sendMessage("hi"); and it worked, with the potion thing in there, but the potion part didnt work

 

Increase the duration of the potion effect to something much higher. Try something like 1000, then go from there.

 

Code:java

 dmgd.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 1, 5));

The 1 in that new PotionEffect represents 1 tick. There are 20 ticks in 1 second. If you want the potion effect to last longer just add how many seconds in ticks.

Example:

Code:java

 dmgd.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 200, 5));
//200 = 10 seconds.

 

Ahhh, it represents ticks. Yeah I'm familiar with ticks, I forgot thats the primary numeration tool in Bukkit XD.
