Saving Obby Checkpoints (DataStore)

Help and Feedback Scripting Support
#1

I have been researching DataStores for a bit and I have to say the process is confusing to say the least. All the videos and forum posts I have watched/read through have helped steer me in the right direction but I am still unsure how to set it up without ruining my script that I already have put together. For reference this is my script that I have below:

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local TweenService = game:GetService("TweenService")
local TweenTime = TweenInfo.new(1)
local Checkpoints = workspace:WaitForChild("Checkpoints"):GetChildren()
local SoundService = game:GetService("SoundService")
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("ObbyDataStore")

local SoundTemplate = Instance.new("Sound")
SoundTemplate.SoundId = "rbxassetid://6979299092"
SoundTemplate.Volume = .2
SoundTemplate.Pitch = 1
SoundTemplate.RollOffMaxDistance = 20
SoundTemplate.RollOffMinDistance = 10

local function FindCheckpoint(character, stage)
    for i, checkpoint in pairs(Checkpoints) do
        local checkpoint_number = tonumber(checkpoint.Name)
        if stage.value == checkpoint_number then
            return checkpoint
        end
    end
end

Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player
    
    local stage = Instance.new("IntValue")
    stage.Name = "Stage"
    stage.Value = 0
    stage.Parent = leaderstats
    
    player.CharacterAdded:Connect(function(character)
        local root_part = character:WaitForChild("HumanoidRootPart")
        local checkpoint = FindCheckpoint(character, stage)
        
        RunService.Heartbeat:Wait()
        root_part.CFrame = checkpoint.CFrame * CFrame.new(0,1,0)
    end)
end)

for i, checkpoint in pairs(Checkpoints) do
    local sound = SoundTemplate:Clone() -- Clone a sound object for each checkpoint
    sound.Parent = checkpoint -- Attach the sound to the checkpoint
    
    checkpoint.Touched:Connect(function(touch)
        local humanoid = touch.Parent:FindFirstChild("Humanoid")
        if humanoid and humanoid.Health > 0 then
            local player = Players:GetPlayerFromCharacter(touch.Parent)
            if player then
                local leaderstats = player:WaitForChild("leaderstats")
                local stage = leaderstats.Stage
                
                local checkpoint_number = tonumber(checkpoint.Name)
                if checkpoint_number - stage.Value == 1 then
                    stage.Value = checkpoint_number
                    
                    -- Play the sound effect when the checkpoint is touched
                    sound:Play()
                    
                    local goal = {
                        Size = checkpoint.Size + Vector3.new(2, 0.5, 2),
                        Transparency = 1
                    }
                    
                    local checkpointclone = checkpoint:Clone()
                    checkpointclone.Parent = workspace
                    
                    local tween = TweenService:Create(checkpointclone, TweenTime, goal)
                    tween:Play()
                    
                    tween.Completed:Connect(function()
                        checkpointclone:Destroy()
					end)
					
					local soundClone = sound:Clone()
					soundClone.Parent = checkpointclone
					
					local soundConnection = soundClone.Playing:Connect(function()
						if soundClone.Playing then
							soundClone:Stop()
							soundClone:Disconnect()
						end
					end)
					
					soundClone:Play()
                end
            end
        end
    end)
end

This script holds the checkpoints as well as the checkpoint sounds/effects. But, I want to have it where, if you leave the game and you’re at a certain checkpoint, it’ll save the data so when you come back, you’ll be back to where you left off at. Any help is much appreciated!

To save the data, you’d have to create a new PlayerRemoving event, and use

local success, errorMessage = pcall(function()
	DataStore:SetAsync("", 0) -- first argument should be the players userid, 
-- second argument is the value that youre saving
end)
-- in a pcall in case the save fails

You’d load that data in basically the same way. Insert this near where you create the value of the checkpoints

local success, checkpoints = pcall(function()
	DataStore:GetAsync("") -- whatever you used to save it
end)

stage.Value = checkpoints

So I would do:

Players.PlayersRemoving:Connect(function(player)
   local sucess, errorMessage = pcall(function()
   DataStore:SetAsync(player.UserId, checkpoints[player.UserId])
end)

And then insert this somewhere else:

local success, checkpoints = pcall(function()
    DataStore:GetAsync("checkpoints")
end)

stage.Value = checkpoints

Would it be something like this? I’m still a beginner scripter so I am unsure about how to set up things.

Can be simplified to:

local success, checkpoints = pcall(DataStore.SetAsync, DataStore, "", 0)

local success, checkpoints = pcall(DataStore.GetAsync, DataStore, "")

plus, the “second argument” part isnt really true.

Assign player checkpoint to a stringvalue (Name it the checkpoint name) then use this.

player.CharacterAdded:Connect(function(character)
    local CheckPoint = Player.CheckPoint.Value
    local SpawnPoint = workspace:FindFirstChild(CheckPoint, true)
    character:MoveTo(SpawnPoint.Position + Vector3.new(0,2,0))
end)

There was a youtube video that had a script like that which I had tried but it unfortunately didn’t work :confused:

#8

What didn’t work?

#9

The script that was provided.
Here’s the video I am referring to: https://www.youtube.com/watch?v=idcsSqPbTPs&t=73s&ab_channel=Septureal
Although, looking over the video, the script is slightly different so I’ll attempt to try that as well! What does it mean to assign player checkpoint to a stringvalue?

I assume you’re using team changes? When you change the player team, change the stringvalue on the player too.

Would I still enter in the same information that I provided but in the shorter terms you provided?

Players.PlayersRemoving:Connect(function(player)
   local sucess, errorMessage = pcall(function()
   DataStore:SetAsync(player.UserId, checkpoints[player.UserId])
end)

local success, checkpoints = pcall(function()
    DataStore:GetAsync("checkpoints")
end)

stage.Value = checkpoints

I’m using Checkpoints that I have made in the workspace that are acting as the stage placeholders seen here:
Capture

The script itself is in ServerScriptService that references the checkpoints in the workspace. I think I know what you’re referring to in terms of team changes but I don’t believe that is something I am using. It’s just a custom leaderboard that I reference in the script itself.

A little update: Yesterday I found a tutorial that was simple enough to follow that ended up helping immensely!
Here is the link to the video if anyone else is struggling with DataStores as well:

I thank everyone for their comments and helpful directions as well! It really does help me understand the topic more :smiley:
