Should use opposite CFrame but not knowing how

I am coding a Zipline, but I’ve run into an error. This video will probably explain the issue:


I don’t want this to be happening, I want the character to keep moving in the same direction, not turning around. I can’t use Position or Orientation, as that would probably break the character using the Zipline.

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
	local Diff2 = 2.6
	
	local RotateP = 0
	
	local Pos = CFrame.new(EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0))
	Pos *= CFrame.Angles(0,math.rad(180),0)

	local Tween = TweenService:Create(
		HRP,
		TweenInfo.new(
			Time,
			Enum.EasingStyle.Linear,
			Enum.EasingDirection.Out,
			0,
			false,
			0
		),
		{
			CFrame = CFrame.lookAt(EndZip.NeonCore.Position, StartZip.NeonCore.Position) * CFrame.new(0,Diff2,0)
		}
	)

	HRP.Anchored = true
	HRP.CFrame = CFrame.new(StartPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0))
	HRP.CFrame = CFrame.lookAt(StartZip.NeonCore.Position, EndZip.NeonCore.Position) * CFrame.new(0,Diff2,0)
	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 are you connecting the player to zip line?

Or perhaps your not at all. This is simply a position tween. I noticed that your CFrame.lookAt() for the tween is looking at the start of the zip line. That’s probably why its turning around.

#3

And should I use :Inverse()? That breaks the tween.

#4

In your last post, you said you used something called look at but it would break because the player was to low. What if you just changed the player’s position do they go over the zip line, then when it breaks it will look right.

#5

The issue here is that the character rotates, the position is good.

#6

That would stop the rotating though. You need to make the same problem that happened here: CFrame.lookAt breaking position then solve that problem so this problem doesn’t exist anymore. You make a problem to solve a problem, then you solve that problem with an easier solution, right?

As xander said earlier,
CFrame = CFrame.new(HRP.Position, EndZip.NeonCore.Position) * CFrame.new(0,Diff2,0)`
try this

That doesn’t work.

#9

Your tween goal should probably be something like this:

--Position of the Opposite end
local goalPos = EndZip.NeonCore.Position

--Look 5 studs behind the position of the opposite end (assuming its front face is pointed toward the start position)
local goalLookAt = goalPos + ((EndZip.NeonCore.LookVector * Vector3.new(1,0,1)) * -5) --Ignores the Y coordinate so no tilting

local goalFrame = CFrame.lookAt(goalPos, goalLookAt)

You may not even really need to clear the Y coordinate depending on the tilt of the end part. In that case you can just remove the Vector3 from the calculation.

#10

I am moving the Character on the Y axis to match the animation.

#11

Adding onto that, it doesn’t really match the “rope”.

#12

The problem is your tween CFrame has no rotation
so the character is slowly rotating to a orientation of 0, 0, 0

local startPosition = StartPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
local endPosition = EndPrompt.Parent.WorldPosition + Vector3.new(0,Diff,0)
local positionOffset = endPosition - startPosition 

local startCFrame = CFrame.lookAt(startPosition, endPosition)
local endCFrame = startCFrame + positionOffset 

HRP.CFrame = startCFrame

local Tween = TweenService:Create(
	HRP, TweenInfo.new(Time, Enum.EasingStyle.Linear), {CFrame = endCFrame}
)
