feat(core): Phase 1 Complete - State Bag Migration & Legacy Bridge

[shadowcoder8]

• Implemented O(1) Inventory Hash Map in xPlayer (server)
• Added State Bag replication for Job, Accounts, Inventory, and Group
• Created client/modules/bridge.lua (The Emulator) to fire legacy events from State changes
• Added 'esx_loaded' State Bag check to prevent Race Conditions during login
• Implemented Initial State Force Trigger in Bridge to ensure HUD population on spawn
• Added 60KB Payload Safety Check to State Bag setters
• Updated fxmanifest.lua to include new bridge module

Phase 1: Core State Bag Migration & Legacy Bridge

Here is the completed Pull Request documentation for the Phase 1 Modernization.

Description

This PR implements a comprehensive modernization of the es_extended core data architecture. It transitions the primary data flow from legacy Server->Client Network Events to a State Bag driven system (OneSync).

Key Features:

• O(1) Inventory: Refactored server-side inventory from an Array to a Hash Map for instant lookups.
• State Bag Replication: Job , Accounts , Inventory , and Group are now replicated via Player(src).state / LocalPlayer.state .
• The "Emulator" Bridge: A new client module ( bridge.lua ) listens to State Bag changes and automatically fires the legacy esx:setJob , esx:setInventory , etc., events to maintain 100% backward compatibility with existing scripts.
• Race Condition Fix: Login sequence now blocks until state.esx_loaded is true, ensuring data is fully available before the player spawns.
• Payload Safety: Added a 60KB safety check to prevent State Bag overflows.

Motivation

1. Performance (O(N) -> O(1)): Legacy ESX used arrays for inventory, meaning checking if a player had an item required looping through the entire inventory (O(N)). The new Hash Map allows instant access (O(1)), significantly reducing CPU time on high-pop servers.

2. Network Optimization: Previously, updating a job or money required a targeted TriggerClientEvent . Now, we simply update the State Bag. OneSync handles the replication efficiently, reducing custom network traffic.

3. The "Empty HUD" Bug: Legacy HUDs often failed to load on spawn because the client event arrived before the UI was ready. The new Initial State Force Trigger ensures that as soon as the player loads, the Bridge forces a local update, guaranteeing the HUD is populated.

Implementation Details

1. The Emulator Bridge ( client/modules/bridge.lua ): This is the core compatibility layer. It uses AddStateBagChangeHandler to listen for data changes.

• Inventory Logic: When LocalPlayer.state.inventory changes (Map), the bridge converts it back into a sorted Array (Legacy format) and triggers esx:setInventory . This tricks legacy resources (like esx_inventoryhud ) into working without modification.

2. Server-Side Refactor ( xPlayer Class):

• xPlayer.inventory is now self.inventory = { ["bread"] = {count=1, ...} } .
• Added SafeStateSet(state, key, value) wrapper to drop payloads > 60KB and warn console, preventing crash loops.

3. Blocking Login ( client/modules/events.lua ): Added a hard wait loop: while not LocalPlayer.state.esx_loaded do Wait(10) end . This effectively pauses the spawn sequence until the Server confirms all State Bags are replicated.

Usage Example

New Modern Access (Recommended):

-- Client-side: Access data directly without callbacks
local job = LocalPlayer.state.job
print("My Job is: " .. job.name)

local cash = LocalPlayer.state.accounts['money']
print("I have $" .. cash)

Legacy Access (Still Supported via Bridge):

-- This still works perfectly thanks to the Bridge!
RegisterNetEvent('esx:setJob')
AddEventHandler('esx:setJob', function(job)
    print("Legacy Job Update: " .. job.name)
end)
