setVolume/Mute previously stored gain without affecting audible output: the
backend only called grabImage() and never opened an audio sink. Switch to
grab() (interleaved video+audio frames), force AV_SAMPLE_FMT_S16 on the
grabber so samples are always interleaved signed 16-bit PCM, open a matching
JavaSound SourceDataLine and write scaled samples per-frame. gain is read
on every block so /videoMute, GUI Mute and the per-tick distance attenuation
now take effect immediately. SourceDataLine.write blocking provides natural
A/V pacing, so the legacy 15ms sleep is dropped when an audio line is open;
sleep is retained as a 60fps cap when there is no audio device.
bump version to 0.3.1.
VideoPlayback now allocates a DynamicTexture per active anchor under a unique
Identifier (registered on Minecraft.getTextureManager()) and pumps RGBA frames
into it via NativeImage.setPixelABGR + DynamicTexture.upload() during the
client tick. Until the backend (JavaCV) produces a first frame, the texture
shows a dark gray placeholder with a thin border so the anchor screen is
visibly present.
VideoAnchorRenderer.submit() now uses SubmitNodeCollector.submitCustomGeometry
with RenderTypes.entityCutout(textureId), drawing a two-sided width×height
quad oriented by Direction.toYRot() + Axis.YP.rotationDegrees. Vertex
attributes use the new VertexConsumer fluent API (addVertex(Matrix4f, ...)
.setColor.setUv.setOverlay(NO_OVERLAY).setLight.setNormal).
JavaCvBackend / WatermediaBackend / WatermediaProbe / VideoBackend are
unchanged — JavaCV is referenced entirely via reflection so the mod jar
remains loadable when the bytedeco classifier jars aren't on the runtime
classpath, in which case the anchor renders its placeholder surface.
- 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.
