Create a Roblox simulator with AI
A simulator repeats a simple action — hit, collect, run — and rewards the repetition. The genre lives on cadence: every minute must give something, and every half hour must change how the game is played.
What makes a good simulator
The core action has to feel good the first time
Sound, a small animation, a number that pops: the collect action is performed thousands of times, so its first second decides everything.
Capacity creates the rhythm
A backpack that fills forces a trip to sell. That trip is a pause, a chance to spend, and the natural place for the next upgrade to be shown.
Zones and rebirth change the game, not just the numbers
A new zone should bring new objects to collect and a new look. Rebirth should reset the counters while unlocking something that was not available before.
The systems to write
- Collecting — The core action, validated on the server, with its cooldown and tool multipliers.
- Inventory and capacity — Current load, maximum, and the upgrades that raise it.
- Zones — Areas unlocked with currency, each with its own collectables and palette.
- Rebirth — A prestige reset that grants a permanent multiplier.
- Saving — Currency, upgrades, zones and rebirths, saved safely.
Common pitfalls
Collection is computed on the client.
The client asks, the server decides. Anything else is farmed by an exploiter within the hour.
A per-frame loop searches for collectable objects.
Use touch events or a timer at a few hertz. A frame loop over hundreds of parts is why simulators lag on phones.
What Nemesis builds for a simulator
Nemesis builds the zones with distinct palettes and writes the server-side collection loop, capacity upgrades, rebirth and saving. In a complete production, screenshots check exposure, contrast and saturation across the map; a short playtest then walks the character through the zones, reads the logs, measures frame time, and console errors go back for fixing.
Visual direction enforced by the quality check: readable, contrasted, rich: distinct zones, machines that stand out.
Frequently asked
How is a simulator different from a tycoon?
A tycoon grows a base; a simulator grows the player. In a simulator you move, collect and upgrade yourself, while a tycoon is about placing machines that produce for you.
How much content does a first simulator need?
Two or three zones, a dozen upgrades and one rebirth tier, with the first rebirth around 20 to 40 minutes in — the benchmark Nemesis uses. Small enough to balance properly before adding more.
