Parent property is locked

Help and Feedback Scripting Support
#1

Whenever I press e the first time it works just fine and when I press off. But when I try pressing E again it says The Parent property of BodyVelocity is locked, current parent: NULL, new parent HumanoidRootPart. How do i fix?

local UserInputService = game:GetService("UserInputService")
local newVel = Instance.new('BodyVelocity')

local function Jump(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.E then
		local hmp = game.Players.LocalPlayer.Character.HumanoidRootPart
		newVel.Velocity = Vector3.new(0,10,0)
		newVel.MaxForce = Vector3.new(10000,10000,10000)
		newVel.P = game.Players.LocalPlayer:WaitForChild("power").Value
		newVel.Parent = hmp
	end
end

local function JumpEnded(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.E then
		local hmp = game.Players.LocalPlayer.Character.HumanoidRootPart
		hmp.BodyVelocity:Destroy()
	end
end

UserInputService.InputBegan:Connect(Jump)
UserInputService.InputEnded:Connect(JumpEnded)

game.Players.LocalPlayer:WaitForChild("power").Changed:Connect(function()
	newVel.P = game.Players.LocalPlayer.power.Value
end)

in the JumpEnded function, you are destroying the BodyVelocity, meaning it no longer exists. Put newVel inside the Jump function so it creates a new one every jump. You could also make a variable that equals nothing and assign a newly created BodyVelocity to it every jump, that is then destroyed when no longer jumping.

local BodyVelocity

function Jump()
    BodyVelocity = Instance.new("BodyVelocity")
end

function DoneJump()
    BodyVelocity:Destroy()
end

local UserInputService = game:GetService("UserInputService")
local newVel = Instance.new('BodyVelocity')

function Jump(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.E then
		local newVel = Instance.new('BodyVelocity')
		local hmp = game.Players.LocalPlayer.Character.HumanoidRootPart
		newVel.Velocity = Vector3.new(0,10,0)
		newVel.MaxForce = Vector3.new(10000,10000,10000)
		newVel.P = game.Players.LocalPlayer:WaitForChild("power").Value
		newVel.Parent = hmp
	end
end

local function JumpEnded(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.E then
		local hmp = game.Players.LocalPlayer.Character.HumanoidRootPart
		hmp.BodyVelocity:Destroy()
	end
end

UserInputService.InputBegan:Connect(Jump)

game.Players.LocalPlayer:WaitForChild("power").Changed:Connect(function()
	newVel.P = game.Players.LocalPlayer.power.Value
end)

I have another problem it does change the power when the value increases

make local newVel = Instance.new('BodyVelocity') into local newVel. Remove the equals. In the JumpEnded function, just do newVel:Destroy()

wait a second i just realized this is all in a local script
