| Subsystem Name | Network Synchronization Protocol |
| Payload Class | PotionLimitSyncPayload.java |
| Payload Identifier | potion-stacker:sync_limit |
| Protocol Phase | Play (clientbound S2C) |
| Codec Implementation | StreamCodec<RegistryFriendlyByteBuf, PotionLimitSyncPayload> |
| Client Receiver | PotionStackerFabricClient.java |
| Server Dispatch Events | ServerPlayConnectionEvents.JOIN, DynamicGameRuleManager listener |
| Menu Synchronization | broadcastFullState() on containerMenu and inventoryMenu |
2. Step-by-Step Player Workflow & Synchronization Lifecycle
Initial Player Connection (Handshake): When a player connects to the dedicated server,
ServerPlayConnectionEvents.JOINtriggers. The server queries current active limits fromPotionStackerManagerand sends aPotionLimitSyncPayloadto the connecting client.Client-Side State Storage: Upon packet receipt on the client,
PotionStackerFabricClientqueues a task on the Minecraft client render thread (context.client().execute(...)) to updatePotionStackerManager.setClientLimit(potionLimit, stewLimit).In-Game Administrator Mutation: An administrator executes
/gamerule potion-stacker-addon:potion_limit 32.DynamicGameRuleManagerdetects the value change and invokesPotionStackerManager.setLimits(...).Full Multi-Client Broadcast & Menu Refresh: The server loops through all online players (
server.getPlayerList().getPlayers()), dispatchesPotionLimitSyncPayload, and invokesbroadcastFullState()on every player's open container and inventory menus.
3. Mathematical Formulas & Network Bandwidth
$$B = \text{VarIntBytes}(P_{\text{limit}}) + \text{VarIntBytes}(S_{\text{limit}})$$
For default settings ($P = 16, S = 16$): $$B = 1 + 1 = 2\text{ bytes}$$
Even at the maximum safe limit ($39{,}768{,}215$): $$B = 4 + 4 = 8\text{ bytes}$$
