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?

Okay, so the best way I can describe this is: Remember how some of OreSpawn's armor sets came with default enchantments as soon as you crafted them/when they were spawned in as a mob drop? That's what my team is trying to do, but they don't know where to get started on it. Not looking to have my hand held, just looking for someone to point us in the right direction.

That's what I got from the launcher output. This has been an ongoing issue, I remember having it in 1.7.10 before as well. I'm in 1.12.2 now. I've tried adjusting everything else that I could, undoing overclocks, changing allocated memory, I've determined it must be Optifine. I tried changing to a different version 3 times (testing all of the E versions) and that didn't help. Is there some other earlier version for 1.12 I can use to fix this? EDITED TO ADD: This also isn't an instantaneous crash. I can play the game for anywhere from 15 minutes to an hour before it does this...it depends case by case.

It would appear I didn't hover over the proper instance of it to prompt the import popup. Thanks.

Eclipse says it doesn't exist; everything I've Googled on the matter says it was given the axe as of 1.10, is this not true?

With ItemStack being deprecated, a lot of this code is simply broken. Is there something I can use to replace the usage of ItemStack in the code? Here's a link to the deobfuscated source code, at the moment I've only dug into the classes in the main package: https://mega.nz/#F!fXxhzAQZ!I3arZVpQpU3vGYAf9fpZqg

I didn't even notice the capitalization error! Thank you so much, it's working perfectly now.

That's the crash report. I do indeed have a ClientProxy class so I'm not sure what I've done wrong. Here's an imgur album of all of my code so far: https://imgur.com/a/avwop Images are in order from main class, to reference class, to item class, to proxy classes.
