- Block/BE/Item: BaseEntityBlock + useItemOn(InteractionResult), useOn(UseOnContext),
setChanged(), loadAdditional(ValueInput) / saveAdditional(ValueOutput) with
getStringOr/getIntOr/getBooleanOr/getFloatOr defaults
- Registries: BuiltInRegistries + ResourceKey + Properties.setId(ResourceKey)
- Networking: CustomPacketPayload.Type + StreamCodec.composite + RegistryFriendlyByteBuf
(note: clientboundPlay/serverboundPlay names in fabric-networking-api-v1 6.3.1)
- Commands: Commands.literal/argument, CommandSourceStack.sendSuccess/sendFailure,
PermissionSet.hasPermission(Permissions.COMMANDS_GAMEMASTER) (level-2 equivalent)
- Client GUI: EditBox / Button / Checkbox / AbstractSliderButton + addRenderableWidget
(no render override; widgets render themselves under the new pipeline)
- Renderer: rewritten as stub against new BlockEntityRenderer<T, S extends BlockEntityRenderState>
pattern (createRenderState / extractRenderState / submit). Stub does not draw a quad yet
— frame upload and dynamic texture surface deferred until Watermedia/JavaCV are
re-audited for Java 25
- Playback: stripped to bookkeeping-only stub (tracks active anchors, no frame pump)
- Client entrypoint: ClientTickEvents.END_LEVEL_TICK (was END_WORLD_TICK), Minecraft.level,
LocalPlayer, Vec3, InteractionResult
./gradlew build passes against MC 26.1.2 + Fabric Loader 0.19.2 + fabric-api 0.149.0+26.1.2.
Block placement, anchor BE, payloads, commands, and GUI are functional; the anchor renders
as the plain block until the new render-state pipeline is wired with a texture.
- net.fabricmc.fabric-loom 1.16-SNAPSHOT (no remap; MC 26.1+ ships unobfuscated)
- gradle.properties: minecraft_version=26.1.2, loader=0.19.2, fabric-api=0.149.0+26.1.2
- Java 25 toolchain
- fabric.mod.json: fabricloader>=0.19.0, java>=25
- Drop multi-version build script + matrix CI (single-target now)
- Backup of 1.21.6/7/8 working tree preserved on mc-1.21.x branch
Source migration to Mojmap names is in progress on follow-up commits;
this commit alone will not build until source files are ported.
