Need help with CFrame regrading bodygyro

Hi, im making a hover car, and I want to change one value of bodygyro.
Heres the line that is causing it

vehicle.Body.BodyGyro.CFrame = CFrame.new(math.rad(rayFront.Position.Y - rayBack.Position.Y),math.rad(body.BodyGyro.CFrame.Rotation.Y),math.rad(body.BodyGyro.CFrame.Rotation.Z))

Full code – Thank you in advance

local player = game.Players.LocalPlayer
local char = game.Workspace:WaitForChild(player.Name)
local humanoid = char:WaitForChild("Humanoid")
local sitanim = humanoid:LoadAnimation(script.SitAnim)
local driving = false
local UIS = game:GetService("UserInputService")
local tw = game:GetService("TweenService")
humanoid:GetPropertyChangedSignal("Sit"):Connect(function()

In your code, you’re using the BodyGyro to control the rotation of the car. If you want to modify the values of the BodyGyro you can modify its properties.

-- Adjusted line to set CFrame for BodyGyro
local rotationY = math.rad(body.BodyGyro.CFrame.Rotation.Y)
local rotationZ = math.rad(body.BodyGyro.CFrame.Rotation.Z)
vehicle.Body.BodyGyro.CFrame = CFrame.Angles(0, rotationY, rotationZ)

This modification extracts the rotation values from body.BodyGyro.CFrame.Rotation and sets the CFrame using CFrame.Angles . This way, you can easily adjust the rotation values before setting the CFrame for the BodyGyro . Adjust the rotation values based on your requirements.

Here’s a modification to your code where I adjusted the line that sets the CFrame for the BodyGyro:

local player = game.Players.LocalPlayer
local char = game.Workspace:WaitForChild(player.Name)
local humanoid = char:WaitForChild("Humanoid")
local sitanim = humanoid:LoadAnimation(script.SitAnim)
local driving = false
local UIS = game:GetService("UserInputService")

humanoid:GetPropertyChangedSignal("Sit"):Connect(function()
    if humanoid.Sit == true then
        sitanim:Play()
        driving = true
        local vehicle = humanoid.SeatPart.Parent
        local body = vehicle.Body
        local params = RaycastParams.new()
        params.FilterType = Enum.RaycastFilterType.Exclude
        params.FilterDescendantsInstances = vehicle:GetChildren()
        game.ReplicatedStorage.Start:FireServer()

        repeat
            local rayFront = workspace:Raycast(body.Front.WorldPosition, Vector3.new(0, -100, 0), params)
            local rayBack = workspace:Raycast(body.Back.WorldPosition, Vector3.new(0, -100, 0), params)

            -- Adjusted line to set CFrame for BodyGyro
            local rotationY = math.rad(body.BodyGyro.CFrame.Rotation.Y)
            local rotationZ = math.rad(body.BodyGyro.CFrame.Rotation.Z)
            vehicle.Body.BodyGyro.CFrame = CFrame.Angles(0, rotationY, rotationZ)

            if body.Position.Y < rayFront.Position.Y + 5 then
                body.BodyVelocity.Velocity = Vector3.new(body.BodyVelocity.Velocity.X, 1, body.BodyVelocity.Velocity.Z)
            else
                body.BodyVelocity.Velocity = Vector3.new(body.BodyVelocity.Velocity.X, -1, body.BodyVelocity.Velocity.Z)
            end
            task.wait()

Hi, your fix did not work! the vehicle can only change 2 degrees to the left and right and stops.

fixed it nvm
Aaaaaaaaaaaaaaaaaa
