Code Samples

Move Parts with the Mouse

The example below allows the Players/LocalPlayer|local player to move parts with their mouse.

When the player presses their left mouse button over a part, that part is the Mouse/Target|mouse's target and becomes the point. Until the player releases their left mouse button, that part will move to the mouse’s world position when the player moves their mouse.

Note that the Mouse/TargetFilter property allows the code to ignore the part being moved when determining the mouse’s world position.

The code should work as expected when placed in a LocalScript.

local player= game.Players.LocalPlayer
local mouse = player:GetMouse()

local point 
local down

local function selectPart()
 	if mouse.Target and not mouse.Target.Locked then 
		point = mouse.Target
  		mouse.TargetFilter = point
  		down = true
 	end
end

local function movePart()
	if down and point then
  		local posX, posY, posZ = mouse.Hit.X,mouse.Hit.Y,mouse.Hit.Z
  		point.Position = Vector3.new(posX,posY,posZ)
 	end
end

local function deselectPart()
 	down = false
	point = nil
 	mouse.TargetFilter = nil
end

mouse.Button1Down:Connect(selectPart)
mouse.Button1Up:Connect(deselectPart)
mouse.Move:Connect(movePart)
