Does anyone know how this is made?

Does anyone have any idea how they made it so that this beam is attached to the surface regarding of its position?

As you can see from this GIF, the beam detects the surface of where it is being placed and adjusts itself to stick on the surface.

it’s basically a part that when you click it uses “Mouse.HIt” and goes to the new “Mouse.Hit” every frame and the part as a decal on it. Give me a minute ill make a demo

Oh so its not a beam?

Okay I’ll wait, thank you!

local UIS = game:GetService("UserInputService")
local Mouse = game.Players.LocalPlayer:GetMouse()

local Event = nil

Mouse.Button1Down:Connect(function()
	newPart = Instance.new("Part", game.Workspace)
	newPart.Name = "PlayerPart"
	newPart.CFrame = Mouse.Hit
	newPart.Orientation = Vector3.new(0,0,0)
	newPart.Anchored = true
	newPart.CanCollide = false
	local firstCFrame = Mouse.Hit
	
	Event = game:GetService("RunService").Heartbeat:Connect(function()
		local Size = firstCFrame.Position - Mouse.Hit.Position
		newPart.Size = Vector3.new(Size.X, 1, Size.Z)
	end)
end)

Mouse.Button1Up:Connect(function()
	Event:Disconnect()
end)

it’s not filtering enabled compliant so if you want the parts to replicate use a remoteevent

Does it really work this way?

Cause the line can bend on hills and slopes in a almost accurate shape

well, not really, they probably did it a different way, I set the Orientation to 0 because I was working on a flat plane and it was causing issues. So they probably did it different. With enough time I could’ve done that, but I don’t feel like spending an hour on this. Sorry!

The way they did it is that the line detects the surface of the terrain and adjusts itself to fit to its shape which idk how they did that.

But anyways thank you for the help.

You can use topography or something like that, there is probably something in the API ref for it
