i decided to make a mixin that changes the unbreaking enchantment to make the item actually unbreakable.
just apply the unbreaking enchantment to whatever item you can apply it to and it would probably work.
the config file is located in config/actuallyunbreaking.json or config/actuallyunbreaking.toml for fabric and forge respectively.
1.16.5+: cloth config is optional if you want a config gui.
1.15.2: you might be able to use configured for a config gui. (i haven't tested this)
1.12.2: mixinbootstrap is required.
maxLevelOnly: only the last level of unbreaking will set the tool to be unbreakable if this is true. default = false
useUnbreakableAtLevel: if this is true, the tool will only be unbreakable at a specified level (overrides maxLevelOnly option). default = false
unbreakableAtLevel: the specified level the tool will be unbreakable at. default = 3
mendingIncompatibility: unbreaking will be incompatible with mending if this is true. default = true
useUnbreakableTag: when the tool takes damage, the unbreakable nbt tag will be added and unbreaking (and mending) will be removed from the tool (you will no longer be able to add unbreaking and mending to the tool) if this is true. default = true
this mod is server side only.
modpacks??
