Why should I sync up the client and the server tick?

Hello,

If you aren’t aware, there is a module by @Quenty for syncing the server and the client’s tick. However, I don’t understand what this is used for. I’m aware it helps with sync between client and server in some way, but what’s the right way to use it? I’d like an example (like a bullet or something), and an explanation. Thanks in advance. :slight_smile:

You may want to use it if you are creating a bullet projectile system(calculating the bullet physics and if it hit on the server, rendering the flying bullet on the client).
You may want to use a synced tick() to compensate for latency. There are many more use cases for this as well.

Can you provide a code example?

Okay, I just wrote some pseudocode for anyone who might need help. I understand this for the most part:


local function onClientEvent(shootPlayer, startCFrame, endCFrame, tweenTime, time0)
    local bullet = ...
    
    local tweenConnection
    tweenConnection = RunService.Heartbeat:Connect(function(delta)
        local time = clock:GetTime() + delta
        local currentTime = time0 - time
        local alpha = currentTime / tweenTime
        alpha = TweenService:GetValue(alpha, Enum.EasingStyle.Linear, Enum.EasingDirection.In)
        bullet.CFrame = startCFrame:Lerp(endCFrame, alpha) -- lerp the bullet’s cframe so it’s synced with all other clients
    end)
end
