Simulator Core – Roblox Pet Simulator Kit

Build your own pet simulator in minutes, not weeks.

Simulator Core is a complete, tested framework for Roblox simulator games. Drop one folder into your game, press Play, and you already have eggs, pets, rebirths, a shop, a leaderboard and data saving, all working together.

What's inside

• 🥚 Eggs with weighted odds. The chances are shown above each egg, and a hatch animation shows a spinning 3D reveal of the new pet.
• 🐾 9 pets with their own 3D look: Cat, Dog, Bunny, Fox, Owl, Panda, Dragon, Unicorn and Phoenix. Pets follow the player and boost coin earnings.
• 🎒 Pet inventory: equip, unequip, "Equip Best" and delete, with 3D previews in every card.
• 🔁 Rebirth system with a scaling cost and a permanent bonus.
• 💰 Tap-to-earn currency with a smooth animated counter and player-list stats.
• 🛒 Shop with 3 Game Passes (2x Coins, extra pet slots, lucky hatch) and coin packs (Developer Products). You plug in your own Game Pass and product IDs.
• 🏆 Global leaderboard of lifetime earnings.
• 💾 Safe data saving: retries, autosave, save on shutdown and duplicate-purchase protection.
• 📱 UI that scales automatically to any screen size, including phones.
• 🔒 Server-authoritative: every hatch, rebirth and purchase is checked on the server.

Customise everything from one file

Rename the currency, add pets, change egg prices and odds, and tune rebirth costs, all in a single, commented Config script. No other script needs to be edited.

Want your own 3D pets? Drop a Model with the pet's name into the PetModels folder and the kit uses it automatically. Want your own eggs in your map? Give any Part the attribute EggId and it becomes a hatchable egg.

Connect your own gameplay

A simple server API lets your scripts reward players:
AddCoins(player, amount), GivePet(player, "Dragon"), GetMultiplier(player)
