Anti-Cheat Basics

Understanding anti-cheat systems and false positives.

Concepts

Server-Side Validation

Validate all important actions server-side:


-- Client sends position
RegisterNetEvent('myresource:setPosition')
AddEventHandler('myresource:setPosition', function(x, y, z)
    -- Validate position is reasonable
    if math.abs(x) > 10000 then return end
    -- Set position
end)

Rate Limiting

Prevent rapid actions:


local lastAction = {}
RegisterNetEvent('myresource:action')
AddEventHandler('myresource:action', function()
    local source = source
    local now = GetGameTimer()
    if lastAction[source] and now - lastAction[source] < 1000 then
        return -- Too fast
    end
    lastAction[source] = now
    -- Process action
end)

False Positives

Common causes:

Network lag
Script bugs
Legitimate edge cases

Best Practices

Log suspicious activity
Review before banning
Provide appeals process
Monitor false positive rate
