[1.12.2] Capability on server side world for client gui.

[Merthew]

I made a capability that i attached to the world. It stores an int and that is about it. I am trying to get that int for a gui overlay when you are holding a certain item. I have looked at passing a packet, however, the error i get is that there is no Gl reference in the thread. I understand that the Gl reference is only called when rendering. How would i go about doing this?

gui overlay

Do this in the RenderGameOverlayEvent. Instead of wherever else you are doing it.

How would i get the server world reference, when i was doing that, it would read the number that had been added since the start of the session. not the total stored.

Then what would be the better way to go about doing this?

[Merthew]

Never mind, i got it to work by setting the nbt of the item to the server's world data and passing that through.

I tried doing something like that but i could not get it working, I may go back and work on it later when i feel a bit more motivated.
