Question about CFrame.Angles

Help and Feedback Scripting Support
#1 
local RunService = game:GetService'RunService'
local Players = game:GetService'Players'
local LocalPlayer = Players.LocalPlayer
local Character = LocalPlayer.Character or LocalPlayer.CharacterAdded:Wait()
local Humanoid = Character:FindFirstChildOfClass'Humanoid'
local RootPart = Character:WaitForChild'HumanoidRootPart'
local RootJoint = RootPart:WaitForChild'RootJoint'
local RootC0 = RootJoint.C0


local MaxTiltAngle = 10

local Tilt = CFrame.new()
RunService.RenderStepped:Connect(function(Delta)
	local MoveDirection = RootPart.CFrame:VectorToObjectSpace(Humanoid.MoveDirection)
	Tilt = Tilt:Lerp(CFrame.Angles(math.rad(-MoveDirection.Z) * MaxTiltAngle, math.rad(-MoveDirection.X) * MaxTiltAngle, 0), 0.2 ^ (1 / (Delta * 60)))
	RootJoint.C0 = RootC0 * Tilt
end)

So I saw this in another topic and I was just mainly confused as to why math.rad(-MoveDirection.X) * MaxTiltAngle is what causes the leaning to the left or right of the character when moving in the negative or positive x direction. Shouldn’t the character sort of turn left or right because it’s the y value? help :sob:

Hi there!

I understand your confusion so let’s break it down:

  1. Understanding MoveDirection:

    • Humanoid.MoveDirection is a normalized vector that indicates the direction the character is trying to move. Its components (X, Y, Z) represent movement in the local space of the character:
      • X: Forward/backward (positive forward, negative backward).
      • Y: Upward/downward (typically not used for leaning).
      • Z: Left/right (positive to the right, negative to the left).

  2. Why math.rad(-MoveDirection.X) * MaxTiltAngle?

    • In the context of the character’s local movement:
      • Negative X (moving backward) causes a tilt backward, which makes sense.
      • Positive X (moving forward) keeps the character upright.
    • The MoveDirection.Z value influences the tilt left or right. However, in this case, math.rad(-MoveDirection.X) is used to control the tilt based on forward/backward movement, which might be an intentional design choice.

  3. Tilt Adjustments:

    • The script uses Tilt:Lerp(...) for smooth transitions, helping to avoid abrupt changes in the character’s orientation.
    • The leaning effect occurs mainly through the X direction because it’s representing the forward motion.

  4. Suggested Changes for Clarity:

    • If you want the character to lean left or right based on the Z component of MoveDirection, you can modify the line like this:
      Tilt = Tilt:Lerp(CFrame.Angles(math.rad(-MoveDirection.Z) * MaxTiltAngle, math.rad(-MoveDirection.X) * MaxTiltAngle, 0), 0.2 ^ (1 / (Delta * 60)))
    • This way, positive Z values would tilt the character to the right, while negative values tilt to the left.

Heres a quick diagram which shows you the x, y and z axis.

I hope this helps clarify.
