Pivot and LookingAt

Hello! I want the cylinder to always face the red cube. How could I do that?

When I do it, the cylinder goes crazy (the image is for reference, but in the real cylinder I have the pivot at the top of the cylinder so that it does not move from a base that supports it)

It sounds like you’re trying to make a turret that points at something. Have you searched for solutions before posting?

At first I tried something like this:

Cube.Position = Vector3.new(-62.5, 2.875, 17)
Cube.Position = Vector3.new(Cube.Position.X + rx, Cube.Position.Y, Cube.Position.Z + rz)
Cylinder.CFrame = CFrame.lookAt(Cylinder.Position, Cube.Position)

But apparently the pivot has some influence

I am trying to aim at the face without modifying the position of the object

#5 
Cylinder.CFrame = CFrame.new(Vector3.new(Cube.Position.X + rx, Cube.Position.Y, Cube.Position.Z + rz)) * CFrame.lookAt(Cylinder.Position, Cube.Position)
#6

this should help!! ************

uhh rx and ez are not defined…

#8 
local rs = game:GetService("RunService")
local xOffset, yOffset, zOffset = 0, 0, 0
local cyl = ...

rs.RenderStepped:Connect(function(dt)
    cyl.CFrame = CFrame.lookAt(cyl.Position, Cube.Position + Vector3.new(xOffset, yOffset, ZOffset)
end)

mess with the offset values; if its looking too high up, reduce yOffset, etc.

It’s more easier than you think, really.

local partA = workspace.PartA --The part that looks
local partB = workspace.PartB --That part that will be looked at

while task.wait(0.05) do
    partA.CFrame = CFrame.lookAt(partA.Position,partB.Position)
end

Also note that you have to use heartbeat instead of renderstepped if you are on server though.

#11

I’d only use RunService’s Heartbeat if the code you run per frame isn’t that big, since it can severely use up memory and performance if so.

#12

I doubt it would use up a enough memory to be noticeable in this situation.

With only one line of code, it won’t.
