Regalia Slots API

v0.0.0-beta.8 - Curios capability double-registration crash

Eighth beta of Regalia Slots API for Minecraft 1.21.1 / NeoForge 21.1.249 (Java 21).

Fixed

• Crash when a mod resolved the real CuriosCapability class (Create's goggles overlay, and any mod referencing top.theillusivec4.curios.api.CuriosCapability): IllegalStateException: Attempted to register capability curios:inventory with existing type interface com.skd.regaliaslotsapi.api.type.capability.ICuriosItemHandler != interface top.theillusivec4.curios.api.type.capability.ICuriosItemHandler. The compat entrypoint declared its own curios:inventory / curios:item capability objects typed against Regalia's interfaces, which collided with the identically-named ones in the copied Curios API the moment a third-party mod class-loaded that class. Only earlier crashes in the render path had been hiding it.

Technical

• CuriosCompatMod no longer creates its own EntityCapability / ItemCapability for the curios ids. It now registers its providers against the verbatim CuriosCapability.INVENTORY / ITEM_HANDLER / ITEM, so third-party mods resolve the exact same capability instances they expect.
• Providers wrap Regalia's implementations in the beta.7 shims (ShimCuriosItemHandler, ShimCurio) so the returned objects implement the top.theillusivec4.curios.* interfaces; the ITEM_HANDLER provider returns the entity's equipped-curios IItemHandler view.

Notes

Regalia Slots API is a library. It adds no content on its own — install it only as a dependency of another mod that requires it, on both client and server. Incompatible with the real Curios mod (shared curios mod id); install one or the other. LGPL-3.0-or-later; the full licence text ships in the jar.
