I am trying to perform some operations with all items with a certain tag.

At the moment I am doing this by iterating over all items with the tag using ForgeRegistries.ITEMS.tags().getTag().

This works, but I am passing in the specific tag directly.

Now I am in the process of moving some things into a config file. In the config file file I want to have a list of items or tags (aka the list will contain both items and tags). I have the list working with just items, but now I need to add the tags.

So the question is: How do I get a TagKey object that can be passed into the getTag() method mentioned above from its string representation?

So as an example I am reading "forge:logs" from the config and want to get ItemTags.LOGS. How can I do this?

Looking into it, I think I could do it by iterating over the output of ForgeRegistries.ITEMS.tags().getTagNames() and then somehow comparing those to the string, but I don't even see an easy way to do that. Also I would like to avoid iterating over a potentially large list, if there is a better way of doing it...

 

I have looked into the ITagManager and TagKey classes, but haven't found a solution.

        var tagManager = ForgeRegistries.ITEMS.tags();
        var tagKey = tagManager.createTagKey(new ResourceLocation("minecraft:logs"));
        var tag = tagManager.getTag(tagKey);

Thank you!

That worked!

I had seen the createTagKey method before, but I thought it was there to create an entirely new tag.... I guess the method is simply named weird or I haven't fully understood some aspect of how these tags work in the background... I would have expected a method doing this to be named 'getTagKey' or 'getKey' or similar...

It's kind of a convoluted process unlike what was evidently available in 1.18.1. They really made a breaking change according to what Kaupenjoe demonstrated in a 1.18.1 tutorial.

I created something similar to what Kaupenjoe has here.
