How to keep this from happening?

Help and Feedback Scripting Support
#1

So here I have a script, that points an object towards a position.

function lookAt(target, eye)
    local forwardVector = (eye - target).Unit
    local upVector = Vector3.new(0, 1, 0)
    -- You have to remember the right hand rule or google search to get this right
    local rightVector = forwardVector:Cross(upVector)
    local upVector2 = rightVector:Cross(forwardVector)
 
    return CFrame.fromMatrix(eye, rightVector, upVector2)
end 
game:GetService("RunService").Stepped:Connect(function()
    --workspace.Part.CFrame = initial:lerp(target, math.min((tick() - s) / TIME, 1))
	workspace.Part.CFrame = lookAt(Vector3.new(0, 0, 0), workspace.Part.Position)
end)

But when I position the brick, exactly where I want it to point towards (Vector3.new(0, 0, 0)) this happens:

The brick disappears, and when I click on the brick in the explorer window, then press " f " The viewport goes black. Is there anything I can do to fix this?

This seems be an edge case problem, the lookAt function the wiki provides isn’t really great Maybe try the one Egomose gave in this post:

I’ve tested your code but using the LookAt function from the wiki and it did the same thing for me as it did for you, and then i tested the one Ego provided and it worked as expected, so yeah this is likely an Edge Case issue

Out of curiosity, how come the viewport goes black when this happens?

i’m actually not sure on that one, it didn’t happen to me when i tried it, maybe it was just some random rendering issue or something.
