Part and Character Torso connected by WeldConstraint being reset on new movements

Help and Feedback Scripting Support
#1

I’ve made a character customization area. Basically, whenever you click and hold down on a large button, it moves a “Stage”, which, as a child, has a WeldConstraint with Part0 being the stage and Part1 being a Character’s Torso.

I do not believe the WeldConstraint is the problem, but it could be. It is created on the client, and everything related is in 1 local script.

Basically, the problem right now is that whenever you click, it resets the position of the stage, (and therefore the character as well,) to the orientation that the server sees, always the same place.

Sorry the contrast is bad, especially in the recording

Script: 
--Make move stage button work
local rotateStageButton = characterCustomization.RotateStageButton
local rotateStageButtonHeldDown = false
local mouseStartedDraggingPosition
local stageShouldRotate = false
local stage = game.Workspace:FindFirstChild("CharacterCustomization").Stage
local lastClientRotation
local lastClientFinalRotation = stage.Orientation.Y
rotateStageButton.MouseButton1Down:Connect(function()
	print("Pressed")
	rotateStageButtonHeldDown = true
	mouseStartedDraggingPosition = UserInputService:GetMouseLocation()
	print(mouseStartedDraggingPosition.X)
	local heartbeat
	stage = game.Workspace:FindFirstChild("CharacterCustomization").Stage
	heartbeat = RunService.Heartbeat:Connect(function()
		print(rotateStageButtonHeldDown)
		if rotateStageButtonHeldDown == true and stageShouldRotate == true then
			if not stage:FindFirstChild("WeldConstraint") then
				local weldConstraint = Instance.new("WeldConstraint")
				weldConstraint.Part0 = stage
				weldConstraint.Part1 = stage.Parent.CharacterModel:WaitForChild("Torso")
				weldConstraint.Parent = stage
				stage.Parent.CharacterModel.Torso.Anchored = false
			end
			if stage and stage.Parent.CharacterModel and UserInputService:GetMouseLocation().X ~= mouseStartedDraggingPosition then
				--if UserInputService:GetMouseLocation().X < mouseStartedDraggingPosition.X then
				if lastClientRotation == nil then
					lastClientRotation = lastClientFinalRotation
				else 
					lastClientRotation = (lastClientFinalRotation - (mouseStartedDraggingPosition.X-UserInputService:GetMouseLocation().X))/250
				end
				stage.CFrame = CFrame.new(stage.Position.X, stage.Position.Y, stage.Position.Z) * CFrame.Angles(0,lastClientRotation,math.rad(stage.Orientation.Z))
				--stage.Parent.CharacterModel:SetPrimaryPartCFrame(CFrame.new(stage.Parent.CharacterModel.PrimaryPart.Orientation.X,stage.Parent.CharacterModel.PrimaryPart.Orientation.Y-mouseStartedDraggingPosition.X-UserInputService:GetMouseLocation().X/100,stage.Parent.CharacterModel.PrimaryPart.Orientation.Z))
				--stage.Parent.CharacterModel.HumanoidRootPart.Orientation = Vector3.new(stage.Orientation.X, (stage.Orientation.Y - mouseStartedDraggingPosition.X-UserInputService:GetMouseLocation().X)/100, stage.Orientation.Z)
				--elseif UserInputService:GetMouseLocation().X >= mouseStartedDraggingPosition.X then
				--stage.CFrame = CFrame.new(stage.Position.X, stage.Position.Y, stage.Position.Z) * CFrame.Angles(0,(stage.Orientation.Y + (mouseStartedDraggingPosition.X-UserInputService:GetMouseLocation().X))/1000,math.rad(stage.Orientation.Z))
				--stage.Parent.CharacterModel.HumanoidRootPart.Orientation = Vector3.new(stage.Orientation.X, (stage.Orientation.Y + mouseStartedDraggingPosition.X-UserInputService:GetMouseLocation().X)/100, stage.Orientation.Z)
				--end
			end

		elseif rotateStageButtonHeldDown == false then
			lastClientFinalRotation = lastClientRotation
			print(lastClientFinalRotation .. " " .. lastClientRotation)
			heartbeat:Disconnect()
		end
	end)
end)

rotateStageButton.MouseLeave:Connect(function()
	rotateStageButtonHeldDown = false
	stageShouldRotate = false
end)

UserInputService.InputChanged:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseMovement and rotateStageButtonHeldDown == true then
		stageShouldRotate = true
	end
end)

UserInputService.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 then
		rotateStageButtonHeldDown = false
	end
end)

There should be no reading of the stage’s position, except in the beginning before it is possible that it could have been moved, and then that variable never changes to that again.

Thanks for all help! :smiley:
