Roblox Remote Events

This one covers the complete pattern for client-server communication in Roblox, from where to put your RemoteEvents in ReplicatedStorage to validating every argument on the server. The security section is the real value: it walks through rate limiting, type checks, damage clamping, and common exploit patterns like argument injection and remote spam. It also clarifies when to use RemoteEvent versus RemoteFunction and why you should never use server-to-client RemoteFunctions, since a frozen client callback will stall your entire server thread. If you're building any multiplayer Roblox game where the client needs to talk to the server, this gives you the patterns and the paranoia you need.

Roblox Remote Events & Functions

RemoteEvent vs RemoteFunction

Type	Direction	Returns value?	Use when
`RemoteEvent`	Any direction	No (fire-and-forget)	Notifying server of player action, broadcasting state
`RemoteFunction`	Client→Server	Yes (yields caller)	Client needs a result back (e.g. fetch inventory)
`UnreliableRemoteEvent`	Any direction	No	High-frequency updates where dropped packets are fine

Default to RemoteEvent. Avoid server→client RemoteFunction — an exploiter's frozen callback stalls your server thread indefinitely.

Where to Put Remotes

Always store Remotes in ReplicatedStorage. Create them from a server Script that runs before any LocalScript.

ReplicatedStorage/
  Remotes/
    DealDamage        (RemoteEvent)
    GetInventory      (RemoteFunction)
    SyncPosition      (UnreliableRemoteEvent)

-- Script in ServerScriptService
local folder = Instance.new("Folder")
folder.Name = "Remotes"
folder.Parent = game:GetService("ReplicatedStorage")

local function make(class, name)
    local r = Instance.new(class)
    r.Name = name
    r.Parent = folder
    return r
end
