Hello?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

CdoingBaddie EntityDamageByEntityEvent, check if damager has strength potion effect, and set the damage to something less.

 

Code:

    @EventHandler
    public void onHit(EntityDamageByEntityEvent evt) {
      if (((evt.getEntity() instanceof Player)) && ((evt.getDamager() instanceof Player))) {
        Player damager = (Player)evt.getDamager();
        if (damager.getActivePotionEffects().contains(PotionEffectType.INCREASE_DAMAGE)) {
          Collection<PotionEffect> effects = damager.getActivePotionEffects();
 
          for (PotionEffect a : effects)
            if (a.getType().equals(PotionEffectType.INCREASE_DAMAGE)) {
              int ampl = a.getAmplifier() + 1;
              evt.setDamage(evt.getDamage() + ampl * 0.15D);
            }
        }
      }
    }

thats the strength back in 1.5

 

Code:

    @EventHandler
    public void onPlayerDamage(EntityDamageByEntityEvent e){     
      if (((e.getEntity() instanceof Player)) && ((e.getDamager() instanceof Player))) {
      Player damager = (Player)e.getDamager();
      if (damager.hasPotionEffect(PotionEffectType.INCREASE_DAMAGE))
      e.setDamage(e.getDamage() / 2.0D);
        }
      }

How u do in 1.6
