State Bag Issues

State bags are a powerful feature in CitizenFX for sharing data between resources, but they can sometimes cause performance issues or errors. This guide covers common state bag issues and their solutions for both server owners and developers.

Common Causes

Rate Limiting
- State bags have built-in rate limiting to prevent abuse
- Rate limits are controlled by server configuration
- Default rate is 75 packets per second
- Default burst limit is 125 packets
- Exceeding limits can cause state bag changes to be dropped
- Use resmon to monitor state bag usage and identify rate limit issues
Size Limitations
- State bags have a size limit of 16KB per entity
- Large state bags can cause performance issues
- Complex nested tables can exceed size limits
Network Issues
- State bag changes are network-synchronized
- High latency can cause delayed updates
- Packet loss can cause missed updates

Server Owner Solutions

1. Rate Limit Configuration

# Add to your server.cfg
set rateLimiter_stateBag_rate 75  # Default rate limit for state bag changes per second
set rateLimiter_stateBag_burst 125  # Default burst limit for state bag changes
set rateLimiter_stateBagFlood_rate 150  # Flood detection rate
set rateLimiter_stateBagFlood_burst 175  # Flood burst limit

The default values are usually sufficient for most use cases. Only adjust these if you have specific needs and monitor with resmon to ensure stability. If you are getting spammed with state bags errors but all your resources are fine and you don't see any signs of misbehavior or abuse or the spam happens for random events like player joins, player deaths etc then you likely need to update these values.

2. Monitoring and Diagnostics

# Use these commands in txAdmin console or server console
resmon  # Monitor resource performance including state bag usage
netgraph  # Monitor network performance
net_statsFile "statebag_metrics.csv"  # Log network metrics to file

3. Network Optimization

# Add to your server.cfg
setr sv_netRateLimit 1048576  # 1MB/s per client
setr sv_netRateLimitBurst 2097152  # 2MB/s burst
setr sv_netRateLimitPerClient 100000  # Per-client rate limit

4. Security Configuration

# Add to your server.cfg
setr sv_filterRequestControl 1  # Enable request filtering
setr sv_requestParanoia 1  # Enable stricter request validation
setr sv_authMaxVariance 2  # Maximum authentication variance
setr sv_authMinTrust 0.5  # Minimum authentication trust level
setr sv_experimentalStateBagsHandler 1  # Enable experimental state bag handler
setr sv_pureLevel 2  # Enable strict file integrity checks

5. Access Control

# Add to your server.cfg
add_ace group.admin state_bag.write allow  # Allow admins to write state bags
add_ace group.user state_bag.read allow    # Allow users to read state bags

Developer Solutions

1. Optimized State Bag Usage

-- Example of optimized state bag usage
local function updatePlayerState(playerId, data)
    -- Batch multiple changes
    local stateBag = Entity(playerId).state
    stateBag:set('data', data, true)  -- true for replicated
    
    -- Use appropriate replication flags
    stateBag:set('position', GetEntityCoords(GetPlayerPed(playerId)), true)
end
 
-- Example of rate-limited updates
local lastUpdate = 0
local function rateLimitedUpdate(playerId, data)
    local currentTime = GetGameTimer()
    if currentTime - lastUpdate < 100 then  -- 100ms between updates
        return
    end
    lastUpdate = currentTime
    Entity(playerId).state:set('data', data, true)
end

2. Size Optimization

-- Example of size-optimized state bag
local function optimizeStateBag(data)
    -- Remove unnecessary data
    local optimized = {
        position = data.position,
        health = data.health,
        armor = data.armor
    }
    
    -- Use appropriate data types
    optimized.position = vector3(
        math.floor(data.position.x * 100) / 100,
        math.floor(data.position.y * 100) / 100,
        math.floor(data.position.z * 100) / 100
    )
    
    return optimized
end

3. Error Handling and Validation

-- Example of robust state bag handling
local function safeStateBagUpdate(playerId, data)
    local success, error = pcall(function()
        local stateBag = Entity(playerId).state
        if not stateBag then
            error('Invalid entity')
        end
        
        -- Validate data size
        local json = json.encode(data)
        if #json > 16000 then
            error('State bag too large')
        end
        
        stateBag:set('data', data, true)
    end)
    
    if not success then
        print('State bag update failed:', error)
        -- Implement fallback or retry logic
    end
end

4. Performance Monitoring

-- Add performance monitoring to your state bag updates
local function monitoredStateBagUpdate(playerId, data)
    local startTime = GetGameTimer()
    
    -- Your state bag update code here
    
    local endTime = GetGameTimer()
    local duration = endTime - startTime
    
    if duration > 10 then  -- 10ms threshold
        print('Warning: State bag update took', duration, 'ms')
    end
end
