How to make a Roblox simulator (with AI)
A Roblox simulator needs four wired-up parts: a tap-to-gain action, a shop, a rebirth system, and a save flow. Forge AI generates all four in 58 seconds — leaderstats, multipliers, and a top-cash leaderboard included.

Tap-to-gain action
Click or tap on a target Part fires a server event that increments leaderstats. Rate-limited per player to prevent auto-clickers.
Shop
Buy upgrades that increase per-tap currency. Configurable upgrade tree, cost scales by purchase count.
Rebirth math
Reset cash to 0, increment rebirth count, multiply per-tap by 1.1 per rebirth (configurable).
Leaderstats
Cash, rebirths, total earned. Visible in the player list HUD.
Save flow
DataStore-backed save on PlayerRemoving + every 60 seconds. Retry-with-backoff.
Top-cash leaderboard
Optional global leaderboard fed by OrderedDataStore. Top 10 visible in a SurfaceGui board.

end)Building a Roblox simulator
Simulator is the easiest genre to ship and the easiest to ruin with auto-clickers. The single most important pattern is server-side tap rate limiting. Forge AI ships it by default: TapRemote rejects fires within 50ms of the last fire (20 taps/sec ceiling). Auto-clickers running at 100 taps/sec still only credit 20 — and a stricter ceiling can be added per-player.
The upgrade tree pattern is data-driven. Upgrades live in a Lua table with name, cost curve (function of owned count), and target multiplier. ShopService reads this table to render the shop UI and validate purchases. Adding a new upgrade is one entry, no new code path.
Rebirth uses the same exponential cost pattern as the tycoon page (1000 × 2^count). Per-rebirth multiplier is +0.1 (10% more cash per tap, compounding across rebirths). Owned upgrades reset by default — keeps progression compelling. Set a flag on individual upgrades to make them persistent across rebirth (premium-only perks).
The save flow is identical to the tycoon: SetAsync with retry, periodic 60-second autosave, BindToClose for graceful shutdown. Cash, rebirth count, owned upgrades persist. The optional cross-server leaderboard uses OrderedDataStore to query top-10 cash holders every 60 seconds — Roblox-side throttling caps the read rate so polling is bounded.

Frequently asked
How do you prevent auto-clickers?+
TapRemote is rate-limited to 20 taps/second server-side. An auto-clicker firing 100 times/second still only credits 20 — and a per-second cap can be added on top.
Can I add multiple shops (pets, weapons, multipliers)?+
Yes. ShopService is a generic upgrade-tree pattern. Add new upgrade categories with their own cost curves and multiplier targets.
How does rebirth interact with the shop?+
Rebirth resets owned upgrades by default — fresh start at higher base multiplier. Configurable: keep some upgrades persistent across rebirth via a flag in the upgrade table.
Does the leaderboard work cross-server?+
Yes. The optional OrderedDataStore-backed leaderboard reads top 10 across all servers. Updates every 60 seconds — Roblox throttles OrderedDataStore reads, so polling is bounded.
What about gamepass perks?+
VIP gamepass grants 2x multiplier, fast respawn, exclusive shop items. Forge wires the gamepass IDs you provide.
