Event Handling Errors

This guide covers common errors related to event handling in FiveM resources and how to resolve them.

Common Event Errors

1. Event Registration Errors

-- Error: Failed to register event 'event:name'

Causes:

Event name conflicts
Invalid event names
Missing event handlers
Resource loading order issues

Solutions:

-- Proper event registration
RegisterNetEvent('event:name')
AddEventHandler('event:name', function()
    -- Event handler code
end)

2. Event Trigger Errors

-- Error: Failed to trigger event 'event:name'

Solutions:

Server-side triggering:

TriggerClientEvent('event:name', source, data)

Client-side triggering:

TriggerServerEvent('event:name', data)

3. Event Security Issues

-- Warning: Unsecured event 'event:name'

Solutions:

Implement proper security checks:

RegisterNetEvent('event:name')
AddEventHandler('event:name', function()
    local source = source
    if not IsPlayerAceAllowed(source, 'resource.event') then
        return
    end
    -- Event handler code
end)

Use proper event naming:

-- Good: Resource-specific prefix
RegisterNetEvent('resource:event')
 
-- Bad: Generic names
RegisterNetEvent('giveMoney')

Event Best Practices

1. Proper Event Structure

-- Server-side event handling
RegisterNetEvent('resource:event')
AddEventHandler('resource:event', function(data)
    local source = source
    
    -- Security checks
    if not IsPlayerAceAllowed(source, 'resource.event') then
        return
    end
    
    -- Input validation
    if not data or type(data) ~= 'table' then
        return
    end
    
    -- Event handling
    -- Your code here
end)

2. Error Handling

RegisterNetEvent('resource:event')
AddEventHandler('resource:event', function(data)
    local success, error = pcall(function()
        -- Event handler code
    end)
    
    if not success then
        print('Event error:', error)
    end
end)

3. Rate Limiting

local lastTrigger = {}
local cooldown = 1000 -- 1 second
 
RegisterNetEvent('resource:event')
AddEventHandler('resource:event', function()
    local source = source
    local currentTime = GetGameTimer()
    
    if lastTrigger[source] and currentTime - lastTrigger[source] < cooldown then
        return
    end
    
    lastTrigger[source] = currentTime
    -- Event handler code
end)

Always implement proper security checks and rate limiting for your events to prevent abuse.
