Yes... When connecting to a server, it does not work, but when I am just in single player, it does... What code should I give?
Here is how I registered it in my Base Mod class:
ModLoader.registerEntityID(EntityProtector.class, "Protector", protID);
ModLoader.addSpawn("Protector", 8, 1, 2, EnumCreatureType.monster);
ModLoader.addLocalization("entity.Protector.name", "Amberoguia Protector");
EntityList.entityEggs.put(Integer.valueOf(protID), new EntityEggInfo(protID, 0xFFB300, 0xFF0000));
And sorry for anything ignorant, but I'm new at this...
