[1.19.4] How to create custom anvil recipes?

[JimiIT92]

I'm trying to create a custom anvil recipe, to make so when you combine two items you get a new one (kinda like the pre 1.20 smithing table recipe system, but for the anvil). So I was curious to see if there is a way to make the recipe like usual, with a json file specifying the recipe type.

Apparently there's currently no way of doing this (at least in vanilla Minecraft), so I'm wondering how can you create such recipes? Is there a custom forge recipe type that you can use? Or you have to rely on the AnvilUpdateEvent only?

Found out that mixins doesn't actually works for this case, so the event is left

Correct there are no recipes for the anvil. The logic is hardwired, see AnvilMenu.createResult()

Forge does not have one. I guess you could try to implement this yourself?

You would need a RecipeSerializer that lets you parse and load recipes for the Anvil using a new RecipeType.

You would then check these recipes in the AnvilUpdateEvent using RecipeManager.getRecipeFor().

To get the recipe manager: player.level -> ServerLevel -> Server -> RecipeManager

 

The devil is always in the detail. There is probably a reason why Mojang or Forge haven't already done this? 🙂

Yeah, maybe that would break things... Will try at some point to do so to see if I can add this. Meanwhile what I've tried is to listen to the event, check the ingredients and if they matches two items for a custom recipe I set the output of the event to the desired result. However for some reason I see the output but can't pick up from the anvil
