When A Player gets hit by a snowball that was thrown by another player

So, I'm trying to make some guns in my plugin, and I'm trying to make the snowball do a certain amount of damage to the player that gets hit.

@EventHandler
public void onSnowballHit(EntityDamageEvent event) {
DamageCause thrownEntity = event.getCause().PROJECTILE;
if (thrownEntity.equals(Material.SNOW_BALL)) {
if (event.getEntity() instanceof Player) {
EntityDamageByEntityEvent e = (EntityDamageByEntityEvent) event;
Player thrower = (Player) e.getDamager();
Player hitPlayer = (Player) e.getEntity();
event.setCancelled(true);
hitPlayer.damage(7.5);
}
}
}
}

This is my current code

 

Aaaaand what's the problem? Any errors?

 

It doesn't do any damage to the player that get hit. In other words, it doesn't do what i want it to do.

When will a DamageCause instance ever be equal to a Material? Those two things are completely different. Instead, check if the damager is an instanceof Snowball.

 

@EventHandler
public void onEntityDamage(EntityDamageByEntityEvent e) {
if (e.getDamager() instanceof Snowball) {

 

Not sure what you mean. So are you saying to do it like this

@EventHandler
public void onEntityDamage(EntityDamageByEntityEvent e) {
if (e.getDamager() instanceof Snowball) {
p.setDamage(args0);

 

@xCyclonez
Not p, e.setDamage(....);
