Hello there,

I am a beginner in Minecraft modding and realy need help.
So can you please tell me how to create a GUI that opens up if u right click a custom block?
In the GUI you should be able to put in 3 Items and proceed them into 1.
I saw many tutorials and read a lot but I still don't understand how this works.

Sorry I can't find any premade tutorials for 1.17 at the moment. It really depends on the version of forge you are using. But here's the rundown:

You want to look at classes such as BeaconBlock, or ChestBlock, BeaconMenu, etc. to help you with these steps, but you need to do the following:
1. Make a block extending BaseEntityBlock (BeaconBlock)
2. Make a block entity for it (BeaconTileEntity)
3. Make a menu for it (BeaconMenu)
4. Make a screen for it (BeaconScreen)

I know it's a little complex, but I'm sure you can find tutorials online, or if someone else comes in to help.

tile entity may not be needed at all.

read the topic again its 1.16.4 and not 1.17 -> the class names being wrong, since he use mcp and not moj mappings

it is required if you want to store data (like a Inventory)

Whoops! Sorry, my fault.

But yes, a block entity (tile entity in 1.16-) *is* needed for storing data (i.e. furnace). But I think what OP is doing is making an item combiner, which doesn't need one
