Help with lazer eyes

I need help tweening the lazer eyes to the target but it doesn’t really work.

local function tweenLazerEyes(leftDirection, rightDirection)
	local leftLazerEyeBone = RootPart.BottomBone.UpperBone.HeadBone.LeftLazerEyeBone
	local rightLazerEyeBone = RootPart.BottomBone.UpperBone.HeadBone.RightLazerEyeBone

	local leftStartPosition = leftLazerEyeBone.WorldPosition
	local rightStartPosition = rightLazerEyeBone.WorldPosition

	local leftLazer = ReplicatedStorage:WaitForChild("Lazer"):Clone()
	local rightLazer = ReplicatedStorage:WaitForChild("Lazer"):Clone()
	
	leftLazer.Size = Vector3.new(leftLazer.Size.X, leftLazer.Size.Y, 0)
	rightLazer.Size = Vector3.new(rightLazer.Size.X, rightLazer.Size.Y, 0)
	
	leftLazer.CFrame = leftLazerEyeBone.WorldCFrame
	rightLazer.CFrame = rightLazerEyeBone.WorldCFrame
	
	leftLazer.Parent = Visuals -- folder
	rightLazer.Parent = Visuals
	
	local leftCenter = leftLazer.Position + leftDirection / 2
	local leftDistance = leftDirection.Magnitude

	local rightCenter = rightLazer.Position + rightDirection / 2
	local rightDistance = rightDirection.Magnitude

	local leftSizeTweenInfo = TweenInfo.new(1, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut)
	local leftSizeTween = TweenService:Create(leftLazer, leftSizeTweenInfo, {Size = Vector3.new(leftLazer.Size.X, leftLazer.Size.Y, leftDistance)})
	leftSizeTween:Play()

	local leftCFrameTweenInfo = TweenInfo.new(1, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut)
	local leftCframeTween = TweenService:Create(leftLazer, leftCFrameTweenInfo, {CFrame = CFrame.new(leftCenter, leftStartPosition)})
	leftCframeTween:Play()
end

local raycastLazerEyesMaxRange = 1000

local function raycastLazerEyes(target) -- target is a basepart
	local leftLazerEyeBone = RootPart.BottomBone.UpperBone.HeadBone.LeftLazerEyeBone
	local rightLazerEyeBone = RootPart.BottomBone.UpperBone.HeadBone.RightLazerEyeBone

	local leftRayOrigin = leftLazerEyeBone.WorldPosition
	local rightRayOrigin = rightLazerEyeBone.WorldPosition

	local leftDirection = (target.Position - leftRayOrigin).Unit * raycastLazerEyesMaxRange
	local rightDirection = (target.Position - rightRayOrigin).Unit * raycastLazerEyesMaxRange
	tweenLazerEyes(leftDirection, rightDirection)
end

Result:


I can’t figure out how to fix this.

Maybe you can make an loop using Coroutine.Wrap()
then using “Resize()”

example:

coroutine.wrap(function()
	while task.wait() do
		script.Parent:Resize(Enum.NormalId.Left,1)
	end
end)()

coroutine wrap doens’t stop your whole script, so thats why i recommend it
Resize() will add more size to selected face of a part

so the loop gonna add +1 size every milisecond to the left side

(that my first time replying a post on this forum, so i hope i can help.)

Thats not the problem, the problem is the cframe.

#4

Why you are tweening the CFrame?

#5

Because if you only tween the size, the lazer would go through the head.

thats why i recommend using Resize() instead of tweens, because it only add more size to an face of the cylinder and not to the two, but for that you would do a loop

Yes but that wouldn’t be smooth.

#8

then use RunService Heartbeat

#9

Yes but I want to use TweenService.

Current Code:

local leftStartPosition = leftLazerEyeBone.WorldPosition

	local leftLazer = ReplicatedStorage:WaitForChild("G-ManLazer"):Clone()

	leftLazer.Size = Vector3.new(leftLazer.Size.X, leftLazer.Size.Y, 0)

	leftLazer.CFrame = leftLazerEyeBone.WorldCFrame

	local leftCenter = leftLazer.Position + leftDirection / 2
	local leftDistance = leftDirection.Magnitude

	leftLazer.CFrame = leftLazerEyeBone.WorldCFrame
	
	local tweenLeftLazerEyesData = {
		Size = Vector3.new(leftLazer.Size.X, leftLazer.Size.Y, leftDistance),
		CFrame = CFrame.new(leftCenter, leftStartPosition),
	}
