Help with C0's Orientation

I don’t usually post in the devforums, but I am once again helpless.

I am having an issue about Tweening C0. The issue is that Orientation’s X which is supposed to be -90, is instead 90. Here is the code:

Back2 = TweenService:Create(Neck, TweenInfo.new(0.7, Enum.EasingStyle.Quad, Enum.EasingDirection.Out), {C0 = CFrame.new(0, 1.547, 0) * CFrame.Angles(math.rad(-90), math.rad(-180), 0)})
Back2:Play()

Result:

If necessary, I also have an extra code that makes the NPC’s head follow the player:

while Facing.Value == true do
			task.wait()
			Dist = (PlayerHRP.Position - PrimaryPart.Position).Magnitude 

			local dir = (PlayerHRP.Position - PrimaryPart.Position).Unit
			local vecA = Vector2.new(PrimaryPart.CFrame.LookVector.X, PrimaryPart.CFrame.LookVector.Z)
			local vecB = Vector2.new(dir.X, dir.Z)
			local dotValue = vecA:Dot(vecB)
			local crossValue = vecA:Cross(vecB)
			local ht = PrimaryPart.Position.Y - PlayerHRP.Position.Y
			local upAngle = math.atan(ht/4)

			local angle = math.atan2(crossValue, dotValue)
			if angle > math.pi/3 then
				angle = math.pi/3
			elseif angle < -math.pi/3 then
				angle = -math.pi/3
			end

			Face2 = TweenService:Create(Neck, TweenInfo.new(0.25, Enum.EasingStyle.Quad, Enum.EasingDirection.Out), {C0 = CFrame.new(Neck.C0.Position) * CFrame.Angles(-upAngle, angle, 0) * CFrame.Angles(math.rad(-90), 0, math.rad(-180))})
			Face2:Play()
			if Facing.Value == false then break end

		end

I have no idea what is causing this. If you have a solution or anything in mind, please do help me out!

Try changing the -90 in the tween create call to 270 instead.

Failing this, would upAngle happen to be 180 degrees (3.14 radians)?
You’re offsetting the 90 degrees by the previous CFrame.Angles call.

I’m on mobile so I’m not sure what you’re trying to achieve here, but fyi CFrame.new() has an overload that points a part in a specific direction: CFrame.new(position, faceLocation)

Exact same result. I forgot to mention that “Back” tween is the tween that I fire after the NPC stops looking at the player (after the player has left the area) supposedly to rotate the Head back to normal.

But for some reason, when I removed the entire head-follow script, the “Back” tween worked fine.

#7

I’m not really familiar with the instance in question, what exactly is it? I’m gonna get put of bed rq and see if I can resolve this.

#8

I don’t fully get your message but I am using a Motor6D to alter the head’s rotation.

#9

Are you able to set the C0 to -90 in the inspector?

#10

I am. I think the problem lies in the head-follow script.

#11

Have you tried this? I believe this is the issue.

Nevermind, I fixed it by changing the 4 in local upAngle = math.atan(ht/4) to Dist, then changed the “Back” tween Angles to 90, 180, 0. Though earlier I still have no idea how 90, 180, 0 discombobulated the head. Thanks for your help!
