Nazuh's QuestService
Nazuh’s QuestService is a versatile easy to use event based Quest System. I originally made this for a commission, but I modified it a bit to release it as an open source resource, so enjoy 
.
Special thanks to these awesome developers for making this OS resource possible:
@stravant- GoodSignal
@loleris - ReplicaService

Unlocked Test World (NOTE: the UI in this test world is NOT tied to the system itself! It’s just something I threw together to visualize your quests. You can implement your UI however you want.): Link
NOTE:
I most likely won’t be providing a creator store link to this resource due to the bad experience
I’ve had with asset moderation in the past.
Setup
Below is an extremely basic implementation of QuestService.ReplicatedStorage.Quests:
return { { -- These two values are required Id = 'TestQuest', MaxValue = 10, -- These two values have default values of 'Unknown'. -- You can edit the default values specific to your -- game in QuestService.LoadableContent.Core.ReplicatedStorage.QuestUtil. DisplayName = 'Defeat Zombies', Description = 'Defeat 10 Zombies!', ReallyCustomQuestValueSpecificToYourGame = 'totally possible!', -- Events for Everything 😃 CompletedCallback = function(Player: Player) print('Completed') end, IncrementCallback = function(Player: Player, NewAmount: number) print('Incremented') end, DecrementCallback = function(Player: Player, NewAmount: number) print('Decremented') end, QuestStartedCallback = function(Player: Player) print('Started') end, QuestRemovedCallback = function(Player: Player) print('Removed') end } } Server:
-- Services local ReplicatedStorage = game:GetService('ReplicatedStorage') local PlayerService = game:GetService('Players') -- Imports local QuestService = require(script.QuestService) -- Local Functions local function PlayerAdded(Player: Player) local QuestProfile = QuestService:InitializePlayer(Player, { }) -- Pass already obtained quests here QuestProfile.QuestStarted:Connect(function(QuestInstance) print(Player.DisplayName, 'Started Quest:', QuestInstance.Id) -- Update data in datastore -- ... end) QuestProfile.QuestRemoved:Connect(function(QuestInstance) print(Player.DisplayName, 'Ended Quest:', QuestInstance.Id) -- Update data in datastore -- ... end) QuestProfile.QuestUpdated:Connect(function(QuestInstance) print(Player.DisplayName, 'Progressed Quest:', QuestInstance.Id) -- Update data in datastore -- ... end) QuestService:AddQuestToPlayer(Player, 'TestQuest') end -- Runtime -- Startup the quest service QuestService:Init() -- Load your base quests into the quest service QuestService:RegisterModule(ReplicatedStorage.Quests, true) PlayerService.PlayerAdded:Connect(PlayerAdded) for _, Player in PlayerService:GetPlayers() do task.spawn(PlayerAdded, Player) end Client:
-- Services local ReplicatedStorage = game:GetService('ReplicatedStorage') local PlayerService = game:GetService('Players') -- Imports --- Quest Controller is automatically loaded into replicated storage, but if you want --- type hints you can move it there before runtime. local QuestController = require(ReplicatedStorage:WaitForChild('QuestController')) -- Runtime QuestController.QuestsLoaded:Connect(function(QuestInstances) print('Quests Loaded', QuestInstances) for _, Quest in QuestInstances do -- The Base Quests are what you previously loaded into -- the quest controller. local BaseQuest = QuestController:GetBaseQuest(Quest.Id) -- ... end -- ... end) QuestController.QuestStarted:Connect(function(QuestInstance) print('Quest Started', QuestInstance) -- ... end) QuestController.QuestRemoved:Connect(function(QuestInstance) print('Quest Removed', QuestInstance) -- ... end) QuestController.QuestUpdated:Connect(function(QuestInstance) print('Quest Updated', QuestInstance) -- ... end) -- Startup the QuestController QuestController:Init() -- Load your base quests into the quest controller QuestController:RegisterModule(ReplicatedStorage:WaitForChild('Quests'))
