Trouble with grabbing (and throwing) objects with the player's mouse

Help and Feedback Scripting Support

Salutations, all. As the title suggests, I am having issues with picking up and throwing objects. I understand that the main problem may be because I’m handling it on the client, but I thought :SetNetworkOwner() let this happen, or perhaps I’m misinterpreting it. Regardless, they appear to sink on the server side yet are fine on the client.

My client code:

game:GetService("RunService").RenderStepped:Connect(function()
	if GrabbedObject then
		GrabbedObject:PivotTo(WorldMouse.CFrame * CFrame.new(5, 0, 0))

	end
end)

game:GetService("UserInputService").InputBegan:Connect(function(Input, Processed)
	if not Processed then
		if Input.UserInputType == Enum.UserInputType.MouseButton1 then			
			if Mouse.Target:IsDescendantOf(workspace:WaitForChild("Workspace"):WaitForChild("Pickupables")) and Mouse.Target.Parent:IsA("Model") and not Mouse.Target.Parent:GetAttribute("Grabbed") then
				GrabbedObject = Mouse.Target.Parent
				
				script:WaitForChild("RemoteEvent"):FireServer("MoveObject", GrabbedObject)

			end
		end
	end
end)

game:GetService("UserInputService").InputEnded:Connect(function(Input, Processed)
	if Input.UserInputType == Enum.UserInputType.MouseButton1 and GrabbedObject then
		script:WaitForChild("RemoteEvent"):FireServer("DropObject", GrabbedObject)
		
		GrabbedObject = nil
		
	end
end)

My server code:

script.Parent:WaitForChild("RemoteEvent").OnServerEvent:Connect(function(Player, Type, Arg1)
	if Type and Type == "MoveObject" then
		GrabbedObject = Arg1

		for i,v in pairs(GrabbedObject:GetDescendants()) do
			if v:IsA("BasePart") then
				v:SetNetworkOwner(Player)

			end
		end
				
		GrabbedObject:SetAttribute("Grabbed", true)
		
	elseif Type and Type == "DropObject" then
		GrabbedObject = Arg1
		GrabbedObject:SetAttribute("Grabbed", false)
				
		for i,v in pairs(GrabbedObject:GetDescendants()) do
			if v:IsA("BasePart") then
				v:SetNetworkOwner(nil)

			end
		end
	end
end)

If anyone can help, then cheers!

You can’t just do this immediately after the client lets go. You need to wait a few seconds.

Well, I set to a 0.1 delay and it might(?) have improved the throwing, however my main issue still lies in that the picked up objects are sinking into the ground on the server side. I do know the reason why, however I’m unsure on how to solve it, is my problem.

Actually, do pardon my previous comment. After a bit more playing around, it seems to be better off than where it was previously, though still not perfect. C’est la vie, though.

Here’s what I changed:

game:GetService("UserInputService").InputEnded:Connect(function(Input, Processed)
	if Input.UserInputType == Enum.UserInputType.MouseButton1 and GrabbedObject then
		script:WaitForChild("RemoteEvent"):FireServer("DropObject", GrabbedObject)
		
		task.wait(0.1)
		
		GrabbedObject = nil

	end
end)

	elseif Type and Type == "DropObject" then
		GrabbedObject = Arg1
		
		task.wait(1)
				
		for i,v in pairs(GrabbedObject:GetDescendants()) do
			if v:IsA("BasePart") then
				v:SetNetworkOwner(nil)

			end
		end
		
		GrabbedObject:SetAttribute("Grabbed", false)

	end

Begrudgingly, I also did add a server mouse tracking, which did solve my sinking issue.

game:GetService("RunService").RenderStepped:Connect(function()
	if GrabbedObject then
		GrabbedObject:PivotTo(WorldMouse.CFrame * CFrame.new(5, 0, 0))
		
		script:WaitForChild("RemoteEvent"):FireServer("MoveObjectToMouse", GrabbedObject)

	end
end)

	elseif Type and Type == "MoveObjectToMouse" then
		GrabbedObject:PivotTo(WorldMouse.CFrame * CFrame.new(5, 0, 0))

Though I’m quite unsure why it’s now doing this:

Something to do with network ownership. What if it was set to the client still?

That might have been it? I moved the MoveObjectToMouse server fire to another part of the script and it stopped freaking out when being dropped. Still having trouble throwing, but I’ll figure something out. Thank you!
