Logical Enchanting

This is my first mod, so please make backups and report any issues! It should be fine but I may be stupid :P

COMPATABILITY (IMPORTANT)

This mod should be compatible with enchantments added from other mods as long as they are capped at level 5. Enchantment costs use hardcoded values dependent on an enchantment's max level, and I do not have a good way to circumvent this other than just writing in more values for higher levels. I may look into expanding compatibility for this in the near future, but for now I'd just like to get this mod out there and fix any major bugs that pop up.

This mod is technically functional when installed serverside-only, but clientside is needed to actually update the anvil UI. Basically, it'll tell you the vanilla experience cost/Too Expensive, even though it lets you take the tool for the correct adjusted cost. As far as I know there's no way to change this solely serverside.

All that aside...

The days of "Too Expensive!" are over!

Logical Enchanting is a complete overhaul to how Minecraft's anvil combination system calculates experience cost, with a few key changes:

No more prior work penalty!^[1]

The cost of an item is solely dependent on it and its ingredients. You'll still save experience by being smart about how you merge enchantments, but no longer is inefficient combining a cascading effect growing faster and faster to unreasonable heights! That's not to say tools with numerous enchantments won't be expensive to maintain, but you can rest assured that the cost will remain constant (until you add even more enchantments, of course)!

Cheap repairing!

Tool repairing, whether through materials or unenchanted duplicates, will incur a constant cost based on the primary tool's enchantment level. Repairing unenchanted tools is completely experience-free! And repairing enchanted tools with materials costs only a single level, no matter how complex the tool is. Sure, using materials to repair is often ignored in favor of crafting a second tool and merging, at least for those items that don't use a whole four materials, but now it could be the difference between breaking and keeping your tool if levels are in short supply...

Constant renaming!

Renaming costs one level. Doesn't matter if you're renaming an unenchanted sword, a sword with every enchant it can hold, a dirt block, or 40 dirt blocks. Feel free to experiment with names without worrying about the cost rising! Ever!

Enchanted book supremacy!

Using an enchanted book to add enchantments is often far cheaper than combining with another tool. Try it out!

^[1] This mod does continue tracking prior work penalty as vanilla would, including adding to it; the mod just overwrites anvil cost and removes the max exp check, effectively disregarding the penalty. It should be safe to install/uninstall in a world, but tools you've maintained with this mod active will almost certainly have hit too expensive if you uninstall.
