About this project
What does DucttapeCore add?
This is a binary patch mod made for my own modpack (contains a crapload of mixins).
Feel free to use it in your modpack too if you want, but if anything breaks, that’s on you!
Here's what it currently does:
Disables specific blocks in specific dimensions
Fixes some UI bugs in HardcoreRevival
Fixes incompatibility between HardcoreRevival and Sync
Gives blindness to invisible players
Adds JEI catalyst compatibility for Quality Tools reforging items
Fixes a bug where certain Global Gamerules configs weren't working
Applying a block texture to a Moving Elevators elevator block copies not only its appearance but also its hardness; the used block is consumed in the process and drops as an item when broken later.
Items taken directly from the Creative inventory will not be assigned a Quality from the Quality Tools mod.
Fixed an issue where custom model blocks from ArchitectureCraft displayed missing-texture particles.
Adjusts lightning sound radius (WIP)
Fixes incompatibility between Robotic Parts internal defibrillator parts and HardcoreRevival (WIP)
Everything can be toggled on/off in the config.
Require Cleanroom!!
Require Mixinbooter!!
used AI to review the source code for the patch and make some code modifications.
