Supporoform

Special Version Notice: This mod is for my modpack, so do not ask for following stuffs: support other MC version, integrations with other mods except mods in modpack.

This is a fork of Tinker's Construct/Hephaestus, contains bug fixes and some slight modifications designed for my modpack.

Also, this is an LTS version only for 1.20.1 fabric. So don't ask me for porting to other version, please use Hephaestus instead.

Fixes

  • Inventory blocks will not drop items correctly.
  • Crash client when you open the gui provide by a broken smeltery.
  • Some recipes cannot be used due to wrong tags.
  • When throwing items directly in to smeltery it will wrongly stack.
  • Crash server when wearing piglin/zombie_piglin head.
  • Piggy backpack will make your chestplate disappear.
  • When trying to fill a container without enough space, it will cause fluid copy. (Now it will deny fluid transfer)
  • When putting a single fuel in heater it will disappear without adding furnace burn time.
  • Fix fluids in smeltery disappear when try to insert/extract fluids to drain in certain conditions.
  • Fix some modifiers cannot use due to wrong datagen.

Modifications

  • Remove skeletons smelt to milk recipes.
  • Updated Star to solve conflict with Thin Air

Capability

Since most code don't have massive modification, mods depend on Hephaestus can be used on Supporoform, but not 100%.

The following mods have tested and can still be used on Supporoform

  • EMI Addon: Extra Mod Integrations

FAQ

Can I just simply replace Hephaestus and this mod with each other?

Yes, you can safely replace it. All registry names are not modified.

Why not just make an addon to fix Hephaestus?

This mod is firstly planned to use some mixins to fix Hephaestus bugs. But after some research I found that there are some code I cannot modify directly, which means some bugs cannot be fixed with addons.
