How to face part to root's face position

Help and Feedback Scripting Support
#1

Hey there! so, im not too familiar with CFrames so i came to the dev forum to ask these questions. i have no idea on how to do this.

how would i face the part to the root face’s front? I have searched and tried everything and it still doesn’t work.

Thanks!!

There’s a CFrame method called lookAt that does exactly this. It takes two Vector3s as arguments:

local origin = workspace.SomePart.Position
local lookAtPoint = (targetChar.PrimaryPart.CFrame * CFrame.new(0, 0, -1)).Position

workspace.SomePart.CFrame = CFrame.lookAt(origin, lookAtPoint)

If I didn’t multiply it by the right axis, you can modify the offset until the results look appropriate.

Doesn’t work, i don’t see the part idk why

(Client)

while task.wait() do
		if cg and root then
			local origin = cg.Position
			local lookAtPoint = (root.CFrame * CFrame.new(0, 0, -1)).Position

			cg.CFrame = CFrame.lookAt(origin, lookAtPoint)
		end
	end

It works fine for me. Any output??

No, wonder if its because of the cg properties

also, i just realized it only rotates the part, how would i make it so it goes into the player too?

i tried

cg.CFrame = root.CFrame

didn’t work

Do you want the part to gradually move towards the player’s facing direction??

Yes

sorry for not actually making it clear in the post :pensive:

You could use an AlignPosition constraint. Give me a second I’ll make a quick demo for you

The script is in StarterPlayerScripts

Hope it helps.

It spins randomly when it gets near to the player

also, im pretty sure the first one doesn’t work and just goes to near spawn sometimes it works

(random spinning)
