How can i move a part only in the Y axis

Hello developers

I’m making a cooking system, and i need to move a part to the position of another part hitted by a raycast.

i will show you the important part of the code:

Mouse.Button1Up:Connect(function()
	
	Clicking = false
	
	if Point then
		
		raycastDownward(Point)
		
		local Highest = nil
		
		-- Check highest part
		
		local Results = raycastDownward(Point)
		
		for _,TheRay in pairs(Results) do
			if not Highest then
				Highest = TheRay
				continue
			end
			
			if TheRay.Instance.Position.Y > Highest.Instance.Position.Y then
				Highest = TheRay
			end
		end

		
		local TSinfo = TweenInfo.new(0.2)
		
		local TsAnim = TweenService:Create(Point,TSinfo,{Position = Highest.Position}) -- Important line
		TsAnim:Play()

		
		--Point.Position = Result.Position

	end

Look at the tween line, i need to move the part to the Highest part found in the rays, the tween does it right, but it moves the part in the three axis, i tried to make Highest.Position.Y inside the tween, but it gives me an error:

So how can i achieve this?

Just use the Y axis value from the Position, don’t use the entire Position. BasePart.CFrame

You are sending the Tween to the Position, not the Position.Y value.
local TsAnim = TweenService:Create(Point,TSinfo,{Position = Highest.Position}) -- Important line

Adding to what @Scottifly has said -

local part = script.Parent

while task.wait(3) do
	part.Position += Vector3.new(0,50,0)
end

Can`t you simply do this?
This would move the part 50 studs on the y-axis consistently [because of the loop]

I can’t do that, i don’t know why, but it gives me an error while doing that.

Also, i can’t use CFrame because Raycasts don’t return CFrames they return Positions

#5

I can’t use Vector3.new() for this i think, because i’m using raycasts to do this job, what the system does is that, i fire Raycasts from the part, when the raycasts hits, the CheckHighestPart section, runs a loop in a array to check which one of the hitted parts with the raycasts, is the higher one in the Y axis, so i can move the ingredient to that Y position

This is an OLD video of this, because now i’m using more than one raycast

Mind sharing the definition of the ‘raycastDownward’ function? Since its results are what is causing the error.

This is the entire code:


--//Services
local Players = game:GetService("Players")
local TweenService = game:GetService("TweenService")

--//Variables
local LocalPlayer = Players.LocalPlayer
local Mouse = LocalPlayer:GetMouse()
local Character = LocalPlayer.Character or LocalPlayer.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local HumanoidRootPart = Character:WaitForChild("HumanoidRootPart")
local CurrentCamera = workspace.CurrentCamera

local RS = game:GetService("ReplicatedStorage")

--//Controls
local Point = nil
local Clicking = false
local tweenInfo = TweenInfo.new(0.1)

--//Initialization
if game.Loaded then
	CurrentCamera.CameraType = Enum.CameraType.Scriptable
	CurrentCamera.CFrame = workspace.CamaraMostrador.CFrame
end

--//Functions

function raycastDownward(part)
	local results = {};
	local raycastParams = RaycastParams.new();
	raycastParams.FilterDescendantsInstances = {part};
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist;

	for _, attachment in next, part:GetChildren() do
		if attachment:IsA("Attachment") and attachment.Name == "RaycastAttachment" then
			local origin = attachment.WorldPosition;
			local direction = Vector3.new(0, -2, 0);
			
			local MidPoint = origin + direction/2
			
			results[attachment] = workspace:Raycast(origin, direction, raycastParams);
			
			
			local Part = Instance.new("Part")
			Part.Parent = game.Workspace
			Part.Anchored = true
			Part.CanCollide = false
			Part.CanTouch = false
			Part.CanQuery = false
			Part.BrickColor = BrickColor.new("Really red")
			Part.Transparency = 0.6
			Part.Size = Vector3.new(0.1,0.1,direction.Magnitude)
			Part.CFrame = CFrame.lookAt(MidPoint,origin)
			
		end
	end

	return results;
end




Mouse.Button1Up:Connect(function()
	
	Clicking = false
	
	if Point then
		
		raycastDownward(Point)
		
		local Highest = nil
		
		-- Check highest part
		
		local Results = raycastDownward(Point)
		
		for _,TheRay in pairs(Results) do
			if not Highest then
				Highest = TheRay
				continue
			end
			
			if TheRay.Instance.Position.Y > Highest.Instance.Position.Y then
				Highest = TheRay
			end
		end

		
		local TSinfo = TweenInfo.new(0.2)
		
		local TsAnim = TweenService:Create(Point,TSinfo,{Position = Highest.Position})
		TsAnim:Play()

		
		--Point.Position = Result.Position

	end
	
	
	Point = nil
	Mouse.TargetFilter = nil
	
end)

Mouse.Button1Down:Connect(function()
	if Mouse.Target and not Mouse.Target.Locked and Mouse.Target:IsA("BasePart") and Mouse.Target:FindFirstChild("Value") then
		Point = Mouse.Target
		Mouse.TargetFilter = Point
		Clicking = true
		
		RS.Sounds.GrabSound:Play()
		
		local TweenAnimation = TweenService:Create(Point, TweenInfo.new(0.2), {Position = Point.Position + Vector3.new(0, Point.Size.Y + 0.5, 0)})
		TweenAnimation:Play()
	end
end)

Mouse.Move:Connect(function()
	if Clicking == true and Point then
		local TweenAnimation = TweenService:Create(Point, tweenInfo, {Position = Mouse.Hit.Position + Vector3.new(0, Point.Size.Y + 0.5, 0)})
		TweenAnimation:Play()

		--[[
		Point.Position = Vector3.new(PosX,PosY,PosZ)
		]]
	 end
end)

Yes, a Raycast measures Position(X,Y,Z) so you should be able to take that Y value and Tween the item just that Y value from its current Position.

Yea, but how do i change the script to make that without the errors?

#10

Take the ‘Highest’ items original Position, and Tween it to the same X and Z Position with the value of the raycast’s Y Position.
