Util Check for attack protection

Checking for attack protection is simply seeing if Player A can attack Player B without being stopped by a plugin. This is extremely important for any plugin that will heal allies, inflict negative effects, or damage a player. Without it, PvP protection can be bypassed through your plugin- meaning Factions members can damage/kill each other, players can fight in no PvP regions, etc.

So, here I present the code I made with partial help from @FisheyLP for anyone who needs to do this check. Use this boolean before you run anything that could possibly result in a protection bypass. The suppress warning is because the method I use is outdated and thus deprecated (I use it because the current method is complicated and not necessary for this purpose):

Code:

public static boolean attackable(LivingEntity attacker, LivingEntity defender) {
        @SuppressWarnings("deprecation")
        EntityDamageByEntityEvent e = new EntityDamageByEntityEvent(attacker, defender, DamageCause.CUSTOM, 1.0D);
        Bukkit.getPluginManager().callEvent(e);
        return !e.isCancelled();
}

This was originally discussed and figured out on http://bukkit.org/threads/getting-if-player-can-attack-other-player.381057/#post-3206131, mainly due to the help of @FisheyLP.

This is a very nice and awesome solution, but maybe post it like this:

Code:

public static boolean attackable(LivingEntity attacker, LivingEntity defender) {
    @SuppressWarnings("deprecation")
    EntityDamageByEntityEvent e = new EntityDamageByEntityEvent(attacker, defender, DamageCause.CUSTOM, 1.0D);
    Bukkit.getPluginManager().callEvent(e);
    return !e.isCancelled();
}
