MineForgeHow to Make Self-Repairing Gear in Minecraft 26.3 (Fabric)
This is the episode the whole series has been building to. Sporesteel is living metal: damaged tools and armor slowly grow back, and they grow back faster in dark, damp places, just like the fungus they came from.
What you need: the Sporesteel project from episode 4, Minecraft 26.3, Fabric Loader 0.20.1, Fabric API 0.165.2+26.3 and Java 25.
How the repair works
Every few seconds, each damaged Sporesteel item a player carries or wears regains a point of durability. The base speed is slow; darkness and water each speed it up.
Ticking items in the inventory
Dark and damp
Showing it to the player
A tooltip line tells players the gear is alive, and a few spore particles show it healing.
Recap
Sporesteel gear now heals itself, faster underground near water. Next episode we polish the mod and publish it to CurseForge.
