Tween rotation taking the long route

Help and Feedback Scripting Support
#1

I have a simple part of this LocalScript that rotates the players’ character depending on what WASD buttons they press, but for some reason, it will rotate the player the longer route instead of going the shorter way.

Section from LocalScript:

local facingDirection = "back"

function rotateCharacter(direction: string)
	if direction == "front" then
		tweenService:Create(player, rotateTweenInfo, {Orientation = Vector3.new(0, 0, 0)}):Play()
	elseif direction == "back" then
		if facingDirection == "right" then
			tweenService:Create(player, rotateTweenInfo, {Orientation = Vector3.new(0, -180, 0)}):Play()
		else
			tweenService:Create(player, rotateTweenInfo, {Orientation = Vector3.new(0, 180, 0)}):Play()
		end
	elseif direction == "left" then
		tweenService:Create(player, rotateTweenInfo, {Orientation = Vector3.new(0, 90, 0)}):Play()
	elseif direction == "right" then
		tweenService:Create(player, rotateTweenInfo, {Orientation = Vector3.new(0, -90, 0)}):Play()
	end

	facingDirection = direction
	print(facingDirection)
end

Hi, I used this LocalScript:

local TweenService = game:GetService("TweenService")
local UserInputService = game:GetService("UserInputService")

local rotateTweenInfo = TweenInfo.new(
	0.2,
	Enum.EasingStyle.Quad,
	Enum.EasingDirection.Out
)

local part = workspace:WaitForChild("Part")

local facingDirection = nil

local directionCFrames = {
	front = CFrame.Angles(0, math.rad(0), 0),
	back  = CFrame.Angles(0, math.rad(180), 0),
	left  = CFrame.Angles(0, math.rad(90), 0),
	right = CFrame.Angles(0, math.rad(-90), 0),
}

local function rotatePart(direction)
	local rotation = directionCFrames[direction]
	if not rotation then return end

	local targetCFrame = CFrame.new(part.Position) * rotation

	if facingDirection ~= direction then
		TweenService:Create(part, rotateTweenInfo, {CFrame = targetCFrame}):Play()
		facingDirection = direction
		print("Part Direction = ", direction)
	end
end

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if gameProcessed then return end
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode == Enum.KeyCode.W then
			rotatePart("front")
		elseif input.KeyCode == Enum.KeyCode.S then
			rotatePart("back")
		elseif input.KeyCode == Enum.KeyCode.A then
			rotatePart("left")
		elseif input.KeyCode == Enum.KeyCode.D then
			rotatePart("right")
		end
	end
end)

to achieve the result you wanted

Interpretation:

When you use Orientation = Vector3.new(...), Roblox rotates the character based purely on the difference in angles. That means if you’re facing right (-90°) and want to face left (90°), it will rotate the long way around (180°), instead of just turning 90° the other direction.

The solution is to use CFrame instead. When you tween the CFrame, Roblox automatically chooses the shortest rotation path, which makes the rotation look more natural and smooth.

  • so u have to change Orientation with CFrame
