Making the spotlight's parent look at mouse's position

Help and Feedback Scripting Support

I’m welding a part that has Spotlight as a child to HumanoidRootPart as .Part1 (parented to the character), and the direction the part looks at seems to be correct.

However, whenever I look down or up, my character decides to fling, and other weird scenarios. What seems to be the issue here?

--light is the Spotlight's parent (part)
light.CFrame = CFrame.lookAt(light.Position, mouse.Hit.p)

Example of the issue.

I’m guessing this is a tool, like a flashlight?
Make sure all the Parts in your tools have the Massless Property set to true so their weight doesn’t affect the Humanoid.

It’s meant to be a flashlight, but it’s a part with a spotlight that gets cloned in the player’s character:

I tried setting the .Massless to true, but it seemed to not help as much.

Not sure if the welding has something to do with this, but I’ll see if I get different results.

local root = char.HumanoidRootPart
		
local clone = light:Clone()
clone.Parent = char; clone.Position = root.Position
		
local weld = Instance.new("WeldConstraint"); weld.Parent = clone
weld.Part0 = clone; weld.Part1 = root

Is that the only Part in the tool, or are there other Parts as well? If there are more then make them all massless.

No, that’s all that’s being cloned, it’s not parented to a tool.

Do you see the Part at all? Why not just instance a Spotlight in the HumanoidRootPart?

The part is always in the same position (to HumanoidRootPart). I wanted to create an effect so the flashlight moves with the cursor (or camera), as seen above - not static in a spot.

Sorry, got distracted and forgot it was aiming with the cursor.
Is it CanCollide on?

The CanCollide is false to the part.

But your Massless is set to false.
Also try turning off CanTouch as well.

Still have the same issue (even with massless). Is there a better alternative for this? I don’t feel like CFrame.lookAt() would do the job here.

Here’s the place file if you want to test it:
flashlightDebug.rbxl (30.5 KB)

local script:

local SL = Instance.new("SurfaceLight")
SL.Parent = game.Players.LocalPlayer.Character.HumanoidRootPart

That should be it i hope… :slight_smile:

You can take advantage of this model I think it is close to the thing you want to do You can give up the tool if you want to

May I suggest using an attachment in the humanoid root part instead?
