Don't forget to load it

Code:

CombatDataLoader.init();

And add this

Code:

xstream.alias("CombatData", CombatData.class);

Usage:

Code:

    public static int getAttackAnim(Entity entity) {
            Player player = (Player) entity;
            int id = player.getEquipment().get(Equipment.SLOT_WEAPON).getId();
            return CombatDataLoader.lookup(id).getAttackAnimation();
    }
