Trying to Save JumpPower in Datastore

[Deadlox85854868 (Mikeyy)]

In my game you can purchase JumpPower upgrades, however though I do not want to make a IntValue that is saved inside a folder called PlayerStats because I feel like there is just an easier approach without having to create a whole bunch of other scripts. Here is the Datastore code:

local datastoreservice = game:GetService('DataStoreService')
local datastore = datastoreservice:GetDataStore("FAKENAME")

local function playerAdded(player)
	local Data = datastore:GetAsync(player.UserId)
	if Data then
		-- Defaults
		player.leaderstats.Wins.Value = Data["Wins"]
		player.leaderstats.Cash.Value = Data["Cash"]
		-- SpeedBoost
		player.Abilities.SpeedBoost.Value = Data["SB"]
		player.Abilities.SpeedBoost.Time.Value = Data["SBT"]
		player.Abilities.SpeedBoost.Cooldown.Value = Data["SCD"]
		-- Blindable
		player.Abilities.Blindable.Value = Data["BL"]
		player.Abilities.Blindable.Time.Value = Data["BLT"] 
		player.Abilities.Blindable.Cooldown.Value = Data["BCD"]
		player.Character:WaitForChild("Humanoid").JumpPower = Data["JP"] -- Error Occurs Here
	end
end

local function playerRemoved(player)
	local success, errorMsg = pcall(function()
		datastore:UpdateAsync(player.UserId, function()
			return {
				-- Defaults
				Wins = player.leaderstats.Wins.Value,
				Cash = player.leaderstats.Cash.Value,
				-- SpeedBoost
				SB = player.Abilities.SpeedBoost.Value,
				SBT = player.Abilities.SpeedBoost.Time.Value,
				SCD = player.Abilities.SpeedBoost.Cooldown.Value,
				-- Blindable
				BL = player.Abilities.Blindable.Value,
				BLT = player.Abilities.Blindable.Time.Value,
				BCD = player.Abilities.Blindable.Cooldown.Value,
				-- Humanoid Saves
				JP = player.Character:WaitForChild("Humanoid").JumpPower, -- Second Error Occurs Here
			}
		end)
	end)
	if errorMsg then
		print(errorMsg)
	end
end

game.Players.PlayerAdded:Connect(playerAdded)
game.Players.PlayerRemoving:Connect(playerRemoved)

game:BindToClose(function()
	wait(3)
end)

Here’s the error that occurs:

ServerScriptService.Stat Handler.Datastore:18: attempt to index nil with 'WaitForChild'  -  Server - Datastore:18

Fixed:

local datastoreservice = game:GetService('DataStoreService')
local datastore = datastoreservice:GetDataStore("DrPhilGame")

local function playerAdded(player)
	local character = player.Character or player.CharacterAdded:Wait() -- Added This
	local Data = datastore:GetAsync(player.UserId)
	if Data then
		-- Defaults
		player.leaderstats.Wins.Value = Data["Wins"]
		player.leaderstats.Cash.Value = Data["Cash"]
		-- SpeedBoost
		player.Abilities.SpeedBoost.Value = Data["SB"]
		player.Abilities.SpeedBoost.Time.Value = Data["SBT"]
		player.Abilities.SpeedBoost.Cooldown.Value = Data["SCD"]
		-- Blindable
		player.Abilities.Blindable.Value = Data["BL"]
		player.Abilities.Blindable.Time.Value = Data["BLT"] 
		player.Abilities.Blindable.Cooldown.Value = Data["BCD"]
		-- Humanoid Saves
		character:WaitForChild("Humanoid").JumpPower = Data["JP"]
	end
end

local function playerRemoved(player)
	local character = player.Character or player.CharacterAdded:Wait() -- Added
	local success, errorMsg = pcall(function()
		datastore:UpdateAsync(player.UserId, function()
			return {
				-- Defaults
				Wins = player.leaderstats.Wins.Value,
				Cash = player.leaderstats.Cash.Value,
				-- SpeedBoost
				SB = player.Abilities.SpeedBoost.Value,
				SBT = player.Abilities.SpeedBoost.Time.Value,
				SCD = player.Abilities.SpeedBoost.Cooldown.Value,
				-- Blindable
				BL = player.Abilities.Blindable.Value,
				BLT = player.Abilities.Blindable.Time.Value,
				BCD = player.Abilities.Blindable.Cooldown.Value,
				-- Humanoid Saves
				JP = character:WaitForChild("Humanoid").JumpPower, 
			}
		end)
	end)
	if errorMsg then
		print(errorMsg)
	end
end

game.Players.PlayerAdded:Connect(playerAdded)
game.Players.PlayerRemoving:Connect(playerRemoved)

game:BindToClose(function()
	wait(3)
end)

It failed to get the players character because the character was not loaded in. Minor mistake. Problem solved.
