[1.18.X] Create Custom Gui

[tristan le plus bg]

I am trying to create a shop in my mods for my minecraft server. And I watch a lot of video about it but It was never working and I look at the forge documentation but nothing was working. (I am trying to do somethings similar to this)

I'm not a expert at Screens and Menus but here a few hints what you have to do or where you can look for examples.

1. Due to the fact that a shop should be handled server-side, I recommend you to use a menu because you can handle button clicks easier
   and you can make sure no data has been modified without permission from a client.
2. Depending on how many trades you want to have in your shop, you will need a scroll bar to properly handle that massive number of trades.
   You can take a look at the StonecutterScreen or the MerchantScreen for an example of a scroll bar.
3. The other stuff is just a bit rendering of a texture (you can use all vanilla Screens for an example), add a few Button and handle the Button click in your Menu.
