So as kinda given by the title, I'm trying to create a custom machine. To be more specific, a machine like a furnace but instead of cooking items, it combines 2 items into one - includes 2 of the same item (actually would like this to be more prioritised over 2 different items). It will also has 1 fuel slot where redstone dust/blocks are used to power it. I have looked up tutorials on custom machines; but they all pretty much involve smelting like a furnace, which I'm not trying to do. I feel like before I finish, I must mention that this is a custom block model machine and not one like a furnace where it just has different textures on the sides. I would also ideally like the fire cooking animation to be different. I believe I have most of the code done for the block itself; but I really need help on the actual functionality of this block. Detailed instructions on what each method would be highly appreciated, as I don't want just code that I don't understand and have no idea how to customise to make different machines.

Here's my code:

Any help would be very appreciated.

Instead of quoting everything that’s wrong, I’m just going to link https://gist.github.com/Cadiboo/fbea89dc95ebbdc58d118f5350b7ba93. Please read it. Descriptions of most of the methods can be found in their javadocs. If those are lacking, you can find out what the method does by finding the usages of it.

 

Im not sure if it’s mentioned in the file I linked, but don’t use ITileEntityProvider, it’s legacy vanilla code and Forge has a better replacement. Simply override hasTileEntity(IBlockState) and createTileEntity(IBlockState) in your block class. To answer your question, all functionality outside of your block just sitting there is implemented through a TileEntity (usually a Tickable one)

So I looked at your conventions; but I still don't understand what I'm supposed to do for registering models and not using an object base class. Like where do I put this registry event and what exactly do I put for it? Also, what do you mean by 'extract it to a helper method'?

Loop over all your items and call the same code you would have in IHasModel. You subscribe to the registry event in the relevant EventSubscriber. Models should go in the client-only event subscriber, Object registration should go in the common/normal event subscriber.

Extract to a helper method means moving the same code that you call a lot into 1 helper method

Could I possibly get examples to help me understand better? I'm much better at understanding things through being shown rather than being told.

Short version:

@SubscribeEvent
public void registerModelsWithoutIHasModelLikeAGoodBoi(ModelRegistryEvent event) {
	modItems.forEach(item -> {
		ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation(item.getRegistryName(), "inventory"));
	});
}

Something like that.

Basically loop through all your items and do what you normally do with IHasModel.

 

Cadiboo's example mod shows how to register stuff with good practices (the complete version); you might want to check that out.

The link is probably somewhere in his signature.

So now when I try and follow Cadiboo's example mod, I now get an error for 'ForgeRegistries', an error for the 'getNameSpace' on the 'onTextureStitchEvent' constructor, and an error for 'getPath' right after that.

What are the errors exactly? You are probably using outdated mappings as my mod was built for the latest mappings.

getResourceDomain -> getNameSpace

getResourcePath -> getPath

onTextureStitchEvent isn’t a class, it’s a method so it can’t have a constructor.

Ah. I should probably update the forge that I'm using thinking about it. But also, are these new mappings still found on the most recommended release for Forge on 1.12? Or only later versions?

Not to mention, 'ForgeDirectories' comes up with an error stating to import it. But when I do, I then get an error for MOD_ID.

Mappings are separate from Forge

 

MCP (Mod Coder Pack) Mappings are what Forge uses to deobfuscate minecraft’s code and turn it into something human-readable.

These mapping names are provided by the community and can change, so it’s relatively important to keep them up to date. You can find a list of mappings here. Simply copy the name/date of the release and put it into your build.gradle file in the minecraftblock.

Interesting. So then do I run the gradlew.bat after that to update it?

You’ll need to run setupDecompWorkspace again (only on 1.12.2 & below) and then refresh the Gradle Project

I honestly don't even remember running that the first time. Where might I find it?

Under gradle tasks

Yep. I'm still completely lost. I don't even know where to start looking to find that.

What IDE do you use? In IntelliJ the gradle tasks and the refresh Gradle Project button are in the gradle pane in the right sidebar. In eclipse I have no idea where it is, but you can use the command line to run gradlew setupDecompWorkspace

well I just did that; but it hasn't seemed to change anything. I tried changing one of the 'getResourceDomains' to 'getNameSpace' and it said it was invalid

Did you rerun the appropriate setup tasks for your IDE & refresh the Gradle Project?

Well I now got that working; but now almost all my classes have errors. Probably because of the outdated things I'm using. For example: CreativeTabs has an error.

CreativeTabs

ItemGroup

That just made things worse. Now it's telling me to create a class for it. I also now have an error for setUnlocalizedName after the mappings update.

MOD_ID also still has an error.

 

1. Show your code.

2. Use your IDE to figure out what methods changed and the replacement for them.

3. Do you know Java?

I was assuming that you had updated to 1.13. CreativeTabs were renamed to ItemGroups in 1.13.

Saying “an error” doesn’t really give us any information that we can use to help you.

*UnlocalisedName -> *TranslationKey

MOD_ID should be replaced by an import of your modid from your main class or constants class.

I think that I use static imports in my 1.12.2 example mod which is apparently hard for many people so I’ve stopped using them on the 1.13 branch

I actually happened to find out that it was TranslationKey myself by going into the Minecraft Item class. And I also fixed the CreativeTabs I believe before reading this. Also, by import of your modid, do you mean like Reference.MOD_ID?

yes
