Convert this from Position to CFrame

Help and Feedback Scripting Support
#1

I am trying to make a zipline and tween the character’s position to the zipline’s end, and I’m using HRP.Position. I’ve heard that you should you CFrame instead of Position, and I wanna do that. Let me show you the differences:

(Position)

(CFrame)

Script 
StartPrompt.Triggered:Connect(function(Player)
	if CharacterValue.Value then return end
	StartPrompt.Enabled = false
	EndPrompt.Enabled = false
	local Character = Player.Character
	CharacterValue.Value = Character
	local Humanoid = Character.Humanoid
	local Animator = Humanoid.Animator
	local HRP = Character.HumanoidRootPart

	local ZipAnim

	local Distance = (Character.HumanoidRootPart.Position - EndZip.NeonCore.Position).Magnitude
	local Time = Distance / 25
	local Diff = 5
	
	HRP.CFrame = CFrame.new(StartPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0))
	HRP.CFrame = CFrame.lookAt(HRP.Position,EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0))

	local Tween = TweenService:Create(
		HRP,
		TweenInfo.new(
			Time,
			Enum.EasingStyle.Linear,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		),
		{
			--Position = EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
			CFrame = CFrame.new(EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)),
		}
	)

	HRP.Anchored = true
	
	if Humanoid.RigType == Enum.HumanoidRigType.R15 then
		ZipAnim = Animator:LoadAnimation(ReplicatedStorage.Animations.ZipLine.AnimR15)
	elseif Humanoid.RigType == Enum.HumanoidRigType.R6 then
		ZipAnim = Animator:LoadAnimation(ReplicatedStorage.Animations.ZipLine.AnimR6)
	end

	Tween:Play()
	ZipAnim:Play()

	Tween.Completed:Wait()

	ZipAnim:Stop()
	HRP.Anchored = false
	CharacterValue.Value = nil
	StartPrompt.Enabled = true
	EndPrompt.Enabled = true
end)

How should I fix this?

i have an idea: put in the position value into the cframe instead of trying to convert it

that way your sort of indirectly converting it

just use CFrame.Position to change a CFrame’s position value

Is there CFrame.Position? How exactly should I change it?

i trust that you know how to do it already since CFrame.Position can be changed if you just put in a vector3

The thing is, how would I do that, and where? Because if I put it in the tween table, it just gives me an error.

{
	CFrame.Position = EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
}

Expected ‘}’ (to close ‘{’ at line 51), got ‘=’

local cframe = CFrame.new()
local newPosition = vector3.new(0,3,0)
cframe.Position = newPosition

print(cframe.Position)

Getting the error

Position cannot be assigned to

maybe try creating a cframe with Only the position data

local CFrame = CFrame.new(Position)

Already doing that, remember? I just need to nullify the rotation.

try this

CFrame.new(Position, Position to look at)

cframe has two arguments

just put vector3 for both of them

This constructor overload has been replaced by CFrame.lookAt , which accomplishes a similar goal. It remains for the sake of backward compatibility.

The thing is that it gives me an error too.

local vector3one = Vector3.new(0,0,0)

local vecot3two = Vector3.new(0,1,0)

local cframe = CFrame.new(vector3one, vecot3two)

print(cframe)

this works fine with no errors

i dont see why you need to use cframe.lootAt

It is a more not buggy method, as the DevHub states.

And I’ve tried your solution, and the character doesn’t rotate, but it doesn’t move as well.

while wait() do
	local vector3one = script.Parent.Position
	local vecot3two = workspace["L85A2 Stock"].Body.Position
	local cframe = CFrame.new(vector3one, vecot3two)
	script.Parent.CFrame = cframe
end

above is the script, below is the visual that came from the results of the script

explain what the buggy part to me is

i have never seen a bug from using CFrame.new

It’s not a rotation issue, as I mentioned, the character isn’t moving.

The buggy method is a method that DevHub doesn’t want the developers use, but it wasn’t removed to not break games.

Hey!

Try This

StartPrompt.Triggered:Connect(function(Player)
	if CharacterValue.Value then return end
	StartPrompt.Enabled = false
	EndPrompt.Enabled = false
	local Character = Player.Character
	CharacterValue.Value = Character
	local Humanoid = Character.Humanoid
	local Animator = Humanoid.Animator
	local HRP = Character.HumanoidRootPart

	local ZipAnim

	local Distance = (Character.HumanoidRootPart.Position - EndZip.NeonCore.Position).Magnitude
	local Time = Distance / 25
	local Diff = 5
	
	local StartCFrame = StartPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
	local EndCFrame = EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
	
	HRP.CFrame = CFrame.new(StartCFrame,EndCFrame)
	
	local Tween = TweenService:Create(
		HRP,
		TweenInfo.new(
			Time,
			Enum.EasingStyle.Linear,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		),
		{
			--Position = EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
			CFrame = CFrame.new(EndCFrame,EndCFrame)
		}
	)

	HRP.Anchored = true

	if Humanoid.RigType == Enum.HumanoidRigType.R15 then
		ZipAnim = Animator:LoadAnimation(ReplicatedStorage.Animations.ZipLine.AnimR15)
	elseif Humanoid.RigType == Enum.HumanoidRigType.R6 then
		ZipAnim = Animator:LoadAnimation(ReplicatedStorage.Animations.ZipLine.AnimR6)
	end

	Tween:Play()
	ZipAnim:Play()

	Tween.Completed:Wait()

	ZipAnim:Stop()
	HRP.Anchored = false
	CharacterValue.Value = nil
	StartPrompt.Enabled = true
	EndPrompt.Enabled = true
end)
