Hello,

Im fairly new to modding, however I am not new to java.

I Want to get an ingredient, in my config file I either wanna specify "minecraft:cobblestone" or "logs", I have these methods to try and deal with that

    private fun resolveItemTag(tagName:String):Tag<Item> =
            ItemTags.getCollection()[ResourceLocation(tagName)] ?: throw RuntimeException("The item tag $tagName does not exist!")

    private fun resolveIngredient(material:String):Ingredient =
        if(material.contains(":")) Ingredient.fromItems(resolveItem(material))
    else Ingredient.fromTag(resolveItemTag(material))

    private fun resolveItem(registryName:String):Item =
            ForgeRegistries.ITEMS.getValue(ResourceLocation("minecraft")) ?: throw RuntimeException("The item $registryName does not exist!")

However I get "The item tag logs does not exist!"

Howdy

Well that code doesn't look much like Java to me so I can't really help you with that.  Except to suggest that

ResourceLocation("minecraft") doesn't contain your registryName parameter.

 

This working example of tags and recipes that use tags might be helpful, perhaps.
