So, one of my coders came up with the idea to do something similar to what ExtraTiC does, and what Magical Crops did back in 1.7, and have a sort of whitelist that registers items based on whether or not another mod is installed. Without going into too much detail as to what we're planning for our mod, we want to add craftable spawn eggs for mobs from other mods (as we've already done this for vanilla mobs and are planning to for our own). Here's where the idea comes in: The person, who unfortunately isn't working with us anymore and can't look into it any further, suggested we create some sort of automated script within our code that will automatically create copies of a main spawn egg class for each mob spawn egg, change a few things for each mob (primarily crafting recipe and what mob it's supposed to spawn), and then register them without us having to write out each individual egg ourselves.

 

I guess my first question is whether it's possible or not? He was pretty much just hypothesizing, so we don't even know if it's possible to do this, and as I said, he left the team so he isn't with us to try and look into this further. If it is possible, where should we be looking as far as ideas for how to build such a script?

Of course it is possible.

You never gave a version so 1.12 you would need an IRecipeFactory implementation and in 1.14.4 you need a IRecipeSerializer that parses your own json recipe format.Create one for each vanilla mob because it makes sense. Then make another one for all the mod entities. I recommend having some way for the user to disable them from within the json. Your Factory or Serializer should also return your own IRecipe implementation.
