Part not moving to Mouse.Hit

Help and Feedback Scripting Support
#1

I am making a simple script that makes a part follow the mouse when the mouse moves, but for some reason it just doesn’t work. I have gotten the game to get the mouse, but the part just doesn’t follow the mouse and I don’t know why. This is all on a LocalScript, by the way.

local Part = game.Workspace.Part
local Mouse = game:GetService('Players').LocalPlayer:GetMouse()
local Mousepos = Mouse.Hit

while true do
	Part.CFrame = Mousepos
	wait()
end
#3

mousepos is more or less a “copy” of mouse.hit. Move it to the inside of the loop.
Also, you will want to add Part to the Mouse’s TargetFilter so that it doesn’t spaz towards the camera.

local Part = game.Workspace.Part
local Mouse = game:GetService('Players').LocalPlayer:GetMouse()

while true do
    local Mousepos = Mouse.Hit
	Part.CFrame = Mousepos
	wait()
end

He is assigning to a CFrame, so he needs to use Mouse.Hit. The caveat is that it will keep the bizzare rotation of the mouse.

My mind got ahead of itself on that one. I posted then realized I typed the wrong response :sweat_smile:

In my mind I just automatically converted it to .p for that reason.

#5

Adding onto this I recommend using RenderStepped instead of a while loop due to it running every frame as well making sure to add a check if mousepos is nil as if the mouse isn’t hitting anything it will return nil and break.

#6

why use RunService when a Mouse.Move event could be used

#7

The part just stays there even if I put the Mousepos in the loop. Is this because it is in a LocalScript?

#8

LocalScript won’t run in a Part, you will have to put it inside StarterGui to make it work.

StarterGui isn’t the only option

#10

I know, but in this situation, StarterGui is the best choice.

#11

Not really, StarterPlayerScripts seems better for this use case.

#12

exactly you aren’t messing with any ui

#13

Oh, I just realized that StarterPlayerScripts also works with LocalScript? Thank you, because I’ve got some trouble with my LocalHandles, alot of them been placed inside StarterGui so it’s pretty messy.

#14

so i made a model for it it should work

#15

I would like to add my soultion:

local Part = game.Workspace.Part
local Mouse = game:GetService('Players').LocalPlayer:GetMouse()

while true do
    Mouse.TargetFilter = Part
    local Mousepos = Mouse.Hit.p
	Part.CFrame = CFrame.new(Mousepos)
	wait()
end

You can add a ‘p’ after Mouse.hit to get the position in vector3.
Mouse.Hit is going to return the position but will also return the rotation of the mouse, you might want to use your own rotation script. :slightly_smiling_face:

Also add a target filter so the Mouse can ignore the Part, or the mouse.Hit.p will keep returning the position of the Part, not the position of where you point the mouse in the workspace.

Use Jared’s solution If you want to keep the bizzare rotation of the mouse.

Optimizations to @Autophilic’s script

local RunService = game:GetService("RunService") -- Services
local Players = game:GetService("Players")

local player = Players.LocalPlayer -- Player stuff
local mouse = player:GetMouse()

local part = workspace:WaitForChild("Part") -- Part stuff
mouse.TargetFilter = part -- So mouse doesn't "hit" the part

RunService.Heartbeat:Connect(function() -- Heatbeat runs after every critical calculation
	if mouse.Target then -- Part doesn't go into space
		part:PivotTo(CFrame.new(mouse.Hit.Position)) -- PivotTo works with parts and models
	end
end)
