How to Make a Simulator Game on Roblox
The Simulator Formula
Simulators follow a proven formula:
Click → Earn → Buy Pets/Upgrades → Unlock Areas → Rebirth → Repeat
Top Simulators to Study
- Pet Simulator X (BIG Games) — $200M+ revenue
- Bee Swarm Simulator — 7+ years of updates
- Muscle Legends — Click-based progression
- Mining Simulator 2 — Resource collection
Core Click System
-- StarterPlayerScripts/ClickHandler.lua
local player = game.Players.LocalPlayer
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local clickEvent = ReplicatedStorage:WaitForChild("ClickEvent")
local UserInputService = game:GetService("UserInputService")
UserInputService.InputBegan:Connect(function(input, processed)
if processed then return end
if input.UserInputType == Enum.UserInputType.MouseButton1
or input.UserInputType == Enum.UserInputType.Touch then
clickEvent:FireServer()
end
end)
-- ServerScriptService/ClickProcessor.lua
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local clickEvent = ReplicatedStorage:WaitForChild("ClickEvent")
clickEvent.OnServerEvent:Connect(function(player)
local ls = player:FindFirstChild("leaderstats")
if not ls then return end
-- Base click value + multipliers
local baseValue = 1
local petMultiplier = player:GetAttribute("PetMultiplier") or 1
local rebirthMultiplier = player:GetAttribute("RebirthMultiplier") or 1
local gamepassMultiplier = player:GetAttribute("GamepassMultiplier") or 1
local totalEarned = baseValue * petMultiplier * rebirthMultiplier * gamepassMultiplier
ls.Coins.Value = ls.Coins.Value + totalEarned
end)
Egg Hatching System
-- ServerScriptService/EggSystem.lua
local EGG_DATA = {
Basic = {
cost = 100,
pets = {
{ name = "Dog", rarity = "Common", chance = 40, multiplier = 1.5 },
{ name = "Cat", rarity = "Common", chance = 35, multiplier = 1.5 },
{ name = "Bunny", rarity = "Uncommon", chance = 15, multiplier = 3 },
{ name = "Dragon", rarity = "Rare", chance = 8, multiplier = 10 },
{ name = "Unicorn", rarity = "Legendary", chance = 2, multiplier = 50 },
}
},
Golden = {
cost = 10000,
pets = {
{ name = "Gold Dog", rarity = "Rare", chance = 30, multiplier = 20 },
{ name = "Gold Dragon", rarity = "Epic", chance = 10, multiplier = 100 },
{ name = "Phoenix", rarity = "Legendary", chance = 1, multiplier = 500 },
}
}
}
local function hatchEgg(player, eggType)
local data = EGG_DATA[eggType]
if not data then return nil end
-- Check if player can afford
if player.leaderstats.Coins.Value < data.cost then return nil end
player.leaderstats.Coins.Value = player.leaderstats.Coins.Value - data.cost
-- Roll random pet
local roll = math.random(1, 100)
local cumulative = 0
for _, pet in ipairs(data.pets) do
cumulative = cumulative + pet.chance
if roll <= cumulative then
-- Award pet to player
addPetToInventory(player, pet)
return pet
end
end
end
Area Unlock System
-- Script inside AreaGate
local gate = script.Parent
local requiredCoins = gate:GetAttribute("RequiredCoins") or 50000
gate.Touched:Connect(function(hit)
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
if not player then return end
if player.leaderstats.Coins.Value >= requiredCoins then
-- Allow passage (make gate transparent)
gate.CanCollide = false
gate.Transparency = 0.8
wait(3)
gate.CanCollide = true
gate.Transparency = 0
end
end)
