[1.16.5] How do i change TileEntity's when I press the button in screenblock?

[Maksimka3168]

I have a block interface in which I use this.addButton(new Button(...)) to create buttons. I need that when clicking on any button, data is saved in Tileentity. The click check occurs in the Screen class, which is inherited from ContainerScreen<...>. How is it possible to get a Tile Entity in this class for further modification. Or are there any other ways?

you need a custom network Packet (for more infos you can take a look at this) which will send all necessary (and only the 100% necessary) data to the server,
on the server you can then modify the TileEntity in the way you want

If it's not difficult, could you give me an example of how custom networks packet should work.

I'm not a fan of just giving people the code they need, so here is a small and simple example of a PacketHandler

with basic java you should be able to modify the packet for your purpose
