Stage value changing for all players

[nix102on (YFPro67)]

hmm… still try it, it might work

[VonsRevenges (Von)]

Yes, that would work correctly do it

It still adds for both players now.

[VonsRevenges (Von)]

My scripts add for one player and do as I said and everything will work correctly.

[nix102on (YFPro67)]

if everything doesn’t work, try that again, I’ve updated my post.

Could you at least explain the changes so the OP knows what are you editing?

[nix102on (YFPro67)]

The script on the client changes the BrickColor of the checkpoint when touched. This ensures that only the touching player sees the color change.
The server script remains responsible for updating the player’s stage stat when they hit the checkpoint.

Using AI for scripts and responses is not a good practice, there is also unnecessary changes that was added to ur script.

Its green for both players and adds the stat for both players. Have I done this right?

I can add some debug code if that helps.

[nix102on (YFPro67)]

add some debug code and let me know alright?

[nix102on (YFPro67)]

I just updated the existing code and provided full code for easy access bro

Try this:
Server Script with RunContext to LEGACY (Don’t switch Client)

local Players = game:GetService("Players")
local ServerStorage = game:GetService("ServerStorage")
local checkpoint = script.Parent
local Debounces = {}

function onTouched(hit)
	local character = hit.Parent
	local player = game.Players:GetPlayerFromCharacter(character)
	if player and character:FindFirstChildOfClass("Humanoid") then
		if not Debounces[player.UserId] then
			Debounces[player.UserId] = true
			local checkpointData = ServerStorage:FindFirstChild("CheckpointData")
			if not checkpointData then
				checkpointData = Instance.new("Folder")
				checkpointData.Name = "CheckpointData"
				checkpointData.Parent = ServerStorage
			end
			
			game.ReplicatedStorage.Stage:FireClient(player,checkpoint,script.Sound)
			
			local userIdString = tostring(player.UserId)
			local checkpointValue = checkpointData:FindFirstChild(userIdString)
			if not checkpointValue then
				checkpointValue = Instance.new("ObjectValue")
				checkpointValue.Name = userIdString
				checkpointValue.Parent = checkpointData

				player.CharacterAdded:Connect(function(character)
					wait()
					local storedCheckpoint = ServerStorage.CheckpointData[userIdString].Value
					character:MoveTo(storedCheckpoint.Position + Vector3.new(math.random(-4, 4), 4, math.random(-4, 4)))
				end)
			end

			checkpointValue.Value = checkpoint
			player.leaderstats.Stage.Value = player.leaderstats.Stage.Value + 1
			print(player)
		end
	end
end

checkpoint.Touched:Connect(onTouched)

Local Script:

game.ReplicatedStorage.Stage.OnClientEvent:Connect(function(checkpoint,sound)
	checkpoint.BrickColor = BrickColor.new("Bright green")
	sound:Play()
end)

Worked perfectly! Thanks everyone for all the help.
