	if (data != null)
	    data.entitySpawned();
}

CommonProxy
        public World getWorld()
{
	return FMLCommonHandler.instance().getMinecraftServerInstance().worldServers[0];

ClientProxy

}

 

In SMP this is catching only once and it is catching before the server has a world instance, which is stopping me from syncing player IEEP info.

What can I do to trigger data.entitySpawned() when the server finishes loading?

 

you shouldnt be getting the world the way you do it there.. in most of the cases u want to be using the world the entity is in and not the overworld.

@SubscribeEvent
public void entityJoinWorld(EntityJoinWorldEvent e)
{
if (e.entity instanceof EntityPlayer && !e.entity.worldObj.isRemote) // can be replaces by if (e.entity instanceof EntityPlayerMP)
	ExtendedProperties.get((EntityPlayer) e.entity).entitySpawned();
}

 

That is all it takes. You don't need IEEP null check nor ANY "proxyfication" of code.

 

For future:

* Learn what Proxy does - there is difference between logical (world.isRemote) and application side (client.jar / dedic.jar).

* Don't ever get world that way.

 

After a little debugging this is now updating the player on join, thanks for the help!

Is EntityJoinWorldEvent, a server side event, or will the client fire this event upon joining a multiplayer server?
