Trying to rotate a player's head a full 360 degrees

#1

Hi, so I’m currently trying to add a spin animation on the player’s head. For whatever reason, when I specify the amount of rotation to about 360, nothing happens. If it’s a smaller number, then it works, but it doesn’t go for the whole 360 degree rotation I’m looking for.

tween_service:Create(headMotor, TweenInfo.new(.3), {C1 = headMotor.C1*CFrame.Angles(0, math.rad(360), 0)}):Play()

headMotor being a Motor6D.

Not really sure what to try here. Any help appreciated, thanks. :slight_smile:

As it’s current state is actually 360 degrees, I mean the same orientation, I think it’s because tweenservice will not tween to equal values
though you can do

local t = tween_service:Create(headMotor, TweenInfo.new(.3), {C1 = headMotor.C1*CFrame.Angles(0, math.rad(359), 0)})
t:Play()
t.Completed:Wait()
 tween_service:Create(headMotor, TweenInfo.new(.06), {C1 = headMotor.C1*CFrame.Angles(0, math.rad(1), 0)}):Play()

That actually doesn’t rotate the head at all as well though. :confused:

Then try tweening the C0, have you tried that?

I just tried, and it’s doing the same thing. I’ve input a high value, like 350, and it rotates nowhere near that rotation in total…

As stated before, TweenService will always take the shortest path possible to rotating. Something you could do is do a bunch of smaller tweens that actually take the correct path:

for i=1, 4 do
local nt = tween_service:Create(headMotor, TweenInfo.new(.0.075), {C1 = headMotor.C1*CFrame.Angles(0, math.rad(i * 90), 0)})
nt:Play()
nt.Completed:Wait()
end

I think this would work?

It seems at though its taking the quickest route towards its goal. Meaning either clockwise or counter-clockwise depending on what’s faster. 180 degrees would always get you the maximum rotation.

So how to fix this: tween your rotation in steps of 180 degrees.

local function tweenRotation(rotation,duration)
	local steps = math.floor(rotation / math.pi);
	local excess = rotation - math.pi * steps;
	local durationPerRadian = duration / rotation;

	for i=1,steps do
		local goal = {C1 = headMotor.C1 * CFrame.Angles(0,math.pi,0)}
		local currTween = tweenService:Create(headMotor,TweenInfo.new(math.pi * durationPerRadian,Enum.EasingStyle.Linear) ,goal);
		currTween:Play()
		currTween.Completed:Wait()   
	end

	-- Account for excess rotation
	local goal = {C1 = headMotor.C1 * CFrame.Angles(0,excess,0)}
	tweenService:Create(headMotor,TweenInfo.new(excess * durationPerRadian),goal):Play();  
end

Edit: Made a bunch of typos, cause I was typing this really fast and on mobile. Another thing I forgot to mention was that this approach would only work if you using a linear tween of course.

Rotate Motor6D using Tween
Saw rotation with orientation

Something I usually do when trying to tween rotations like this is I create a temporary NumberValue that acts as the degree and tween that instead. It should be something like this:

local angle = Instance.new("NumberValue")

RunService.Heartbeat:Connect(function()
    headMotor.C1 = CFrame.new(headMotor.C1.Position) * CFrame.Angles(0, math.rad(angle.Value), 0)
end)

TweenService:Create(angle, tweenInfo, {
    Value = 360;
}):Play();

[EDIT 1/7/2022]: Instead of using NumberValues and tweening them, it would probably work better to use a spring.
