[1.12]? Registering items with data ids


jonesto95

Recommended Posts

Hi

I'm making a mod that contains, among other things, colored wood. I originally went about this in previous versions by making a separate item class for each color and each wood type combination. I know this is extremely inefficient, but I don't know how to handle data values in the code (I'll probably need two if possible, one for the color and one for the wood type). 

How do I go about working with data id values to the colored wood blocks?

Data values and NBT tags are two different things. The data value is an integer, and you can only have one data value per item/item stack. So if you're trying to keep track of both color and wood type, unless you can represent all combinations of those things within a single integer from 0 to 15, you can't use data values for it.

But overall, even if you're using NBT tags for this, it's pretty easy. You'd register all your possible item variant model locations with ModelLoader.registerItemVariants(), then you'd supply a customMeshDefinition function that does the logic to determine which model should be used at any given time. Check out this tutorial file for a bit more clarity: https://github.com/McJty/ModTutorials/blob/master/src/main/java/mcjty/modtut/items/MultiModelItem.java

 

Note that the customMeshDefintion function can have any logic you want, whether it be based on the item stack's metadata, NBT tags, or anything else that can be obtained from an ItemStack within the Item class.

Whatever Minecraft needs, it is most likely not yet another tool tier.

Ok, I got around to looking at the code, it seems the item just toggles between being red and blue upon a right-click. I don't see how you can make a .json recipe file that produces a red item as opposed to a blue one, which is what I ultimately need for my mod, to be able to craft these specific colors with dyes (sorry I didn't specify that before).

Let's say I'll make a class for each wood type. That now allows for us to use data values for the blocks, how would I go about doing that instead of NBT tags?

Ok, further update.

I managed to get 16 colored blocks in using the data tags, now I only have one question:

How would I specify the names and textures of each block? I added one line in the .lang and it wound up renaming all 16 of them at once.

Uh.

The 0-15 limit is for blocks. Item stacks have a limit of 0-32,000 (and a bit).

Blocks and ItemBlocks aren't the same thing, still.

Blocks in the world can only contain metadata (0-15) and nothing else. If you want additional data, you need a TileEntity (NBT does not apply to blocks).

Right, but if you try representing more than 16 blocks with an ItemBlock, then as soon as it's placed in the world, all hell will break loose. (And by that, I mean "it won't work".)

I've settled with making separate ColoredOak, ColoredBirch, etc. classes, so now I'm just dealing with the color per wood type (just like wool, concrete, beds, etc.)

Which you can easily do by using the data value of the ItemBlock; as far as I know, when an ItemBlock is placed in the world, it calls the block's getStateForPlacement() method and passes its metadata in (which, by default, passes the metadata into the getStateFromMeta() method). So you can take that metadata in that method and convert it to the proper block state for your color, and return that.

Only if you naively try to convert from item meta to block meta.

But yes.

    • Hello. I've been having a problem when launching minecraft forge. It just doesn't open the game, and leaves me with this "(exit code 1)" error. Both regular and optifine versions of minecraft launch just fine, tried both with 1.18.2 and 1.20.1. I can assure that my drivers are updated so that can't be it, and i've tried using Java 17, 18 and 21 to no avail. Even with no mods installed, the thing won't launch. I'll leave the log here, although it's in spanish: https://jmp.sh/s/FPqGBSi30fzKJDt2M1gc My specs are this: Ryzen 3 4100 || Radeon R9 280x || 16gb ram || Windows 10 I'd appreciate any help, thank you in advance.
    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
