AutoRejoin - Anti-AFK System

AutoRejoin — Anti-AFK System
Keep your players in-game forever. No more idle kicks.

The Problem

Roblox automatically kicks players after 20 minutes of inactivity. For idle games, tycoons, AFK farming games, and simulators — this kills your player retention and session time.

The Solution

AutoRejoin detects when a player has been idle for 18 minutes (2 minutes before the kick) and automatically teleports them back to the same server. The player never gets disconnected — they seamlessly rejoin with all progress intact.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Features

Smart Idle Detection — Tracks mouse, keyboard, and touch input. Timer resets on any activity.
Same-Server Rejoin — Uses TeleportToPlaceInstance to return the player to the exact same server, not a random one.
Fallback Teleport — If same-server fails (server closed), falls back to any available server.
Studio Detection — Automatically disables in Roblox Studio (TeleportService doesn't work there). No errors in your output.
Retry Logic — 3 attempts for same-server, 3 attempts for any-server. Robust against transient failures.
Lightweight — Single LocalScript, no dependencies, no server-side code needed.
Zero Configuration — Drop it in and it works. No setup, no remotes, no datastores.
Mobile + PC + Console — Works on all platforms. Touch input tracked for mobile.

How It Works

Code:

Player joins game
    ↓
Script starts tracking input (mouse, keyboard, touch)
    ↓
Every 10 seconds: check time since last input
    ↓
If idle ≥ 18 minutes:
    ↓
Attempt 1: TeleportToPlaceInstance (same server)
    ↓ (if fails)
Attempt 2: Teleport (any server)
    ↓
Player is back in-game — no disconnect!
