Both components had incorrect Parse/Serialize implementations that would cause packet deserialization misalignment when encountered in-game. PotionContentsComponent (3 bugs): - Serialize unconditionally wrote VarInt(PotionId) and Int(CustomColor) even when HasPotionId/HasCustomColor was false. The official format (PotionContents.STREAM_CODEC) uses Optional encoding: Bool(hasValue) followed by the value only when true. The extra bytes caused all subsequent fields in the packet to be read at wrong offsets. - Serialize omitted the VarInt(count) prefix for the custom effects list. The official codec uses ByteBufCodecs.list() which always writes a VarInt count header before the list elements. - Also fixed typo: PotiononId -> PotionId. InstrumentComponent (3 bugs): - The official Instrument.STREAM_CODEC uses ByteBufCodecs.holder() which encodes as VarInt(holderId): 0 = inline data, N>0 = registry ref (N-1). The SoundEvent field inside uses the same holder pattern. The old code unconditionally read SoundName (ResourceLocation) and HasFixedRange/ FixedRange even when SoundEventHolderId != 0 (registry reference case has no inline data). - UseDuration was read/written as Float, but the official codec uses ByteBufCodecs.VAR_INT. This caused a 4-byte vs variable-length mismatch that would shift all subsequent data. - HasFixedRange was read unconditionally when SoundEventHolderId == 0, but FixedRange was also read unconditionally. The official SoundEvent DIRECT_STREAM_CODEC uses Optional<Float> encoding: Bool(hasValue) followed by Float only when true. These components are used for potion items and goat horns respectively. Verified against official 1.20.6 decompiled source: - net.minecraft.world.item.alchemy.PotionContents (STREAM_CODEC) - net.minecraft.world.item.Instrument (STREAM_CODEC/DIRECT_STREAM_CODEC) - net.minecraft.sounds.SoundEvent (STREAM_CODEC/DIRECT_STREAM_CODEC) - net.minecraft.network.codec.ByteBufCodecs (holder/optional/list) Made-with: Cursor |
