Creating a custom tile entity with a container and binding it to already registered custom block

[applegod]

I think the title is pretty self-explanatory. I have experience with Java & Minecraft (I started with coding spigot plugins), however I am new to Forge.

 

I have decided that I want to make mods for the newest version (1.16.4), but soon realised there aren't many (almost none) tutorials for this version. I especially cannot figure out (after hours of searching through original Minecraft code) how to create a block that has it's own inventory that can be interacted with and saves when closed. I kinda figured out it has to do with tile entities but because of my lack of knowledge of the Forge API (the docs aren't helpful around this theme whatsoever) when I tried creating something related to tile entities I always encountered some stupid errors that I don't even remember yet.

 

I would really appreciate any help I can get around this topic because it doesn't seem so straight forward. What I am mainly looking for here is complete code of a fully working yet simple block which basically just stores items (or later even a custom furnace) and upon right click opens a container (inventory/gui) in which these items are stored (for the most part I have already figured this part out) from which I could learn more about this topic.

 

PS: I already have my block registered and working in game.

Tile enntities haven't changed significantly in several versions. 

 

Override hasTileEntity and createTileEntity in your block class.

Yeah but for that I need a custom tile entity class and a custom tile entity type and register all that don't I?

Could you provide me with any sort of a code example for this?

I understand that there are these functions that create the tile entities etc. but I just don't get how they are generally connected whatsoever.

I think studying a bit this example will give you useful informations: https://github.com/TheGreyGhost/MinecraftByExample/tree/working-1-16-4/src/main/java/minecraftbyexample/mbe30_inventory_basic

It explains how to create a basic chest-like block. The code is very well documented

Yes. Which is where you store the inventory. You can't store it anywhere else...

Vanilla code is a pretty good resource. Just ignore anything about IInventory and use the Forge supplied Capabilities system instead.

Hey, thanks for the advice, I looked into this and got inspired. I'm pretty sure everything works now but when I try to open the container I get an error that says:
[14:09:56] [Render thread/WARN] [minecraft/ScreenManager]: Failed to create screen for menu type: modId:apple_smelter_container

 

I don't really understand where the mistake happened. Should I post my code?

That error happens when you did not register an IScreenFactory for your container type.

You can post your code if you can't figure it out.

Thanks, I understand that's done with 

ScreenManager.registerFactory(StartupCommon.containerTypeContainerBasic, ContainerScreenBasic::new);

But where should I put this? In my main startup class next to my bus registries?

FMLClientSetupEvent with enqueueWork.

Alright thanks, is that mod event bus or forge event bus? And how can I convert the registerFactory() function to a runnable/work which I can enqueue?

Just use a lambda expression.

event.enqueueWork(() -> ScreenManager.registerFactory(StartupCommon.containerTypeContainerBasic, ContainerScreenBasic::new));

Used this and everything works perfectly now!
Thank you so much.
