Alternate methods for opening a GUI

[Jershy 0]

The normal way to call on a GUI seem to be by referring to an ID, which opens an instance of that Gui that has already been declared in the handler. However, my Gui needs an Interface to be passed through the constructor of that Gui. Is there any alternate method to call the Gui so that I can get a chance to pass in my variables?

What interface, where is it stored?

The interface works similar to IMerchant which helps communicate between an entity and the Gui.

You have to realize how this works in vanilla. The

IMerchant

instance doesn't magically get transferred over the network. The client always uses an implementation called

NpcMerchant

. You have to do the same.

[Jershy 0]

where is it implemented? I've been through the code the villager class and IMerchant, and haven't found any reference to it.
