我如何找到roblox lua中角色部分的方向？

我正在为我的角色添加腰带，但每当我添加腰带时，无论角色的方向如何，腰带都会朝一个方向。如何使我的人形根部分所面对的方向与腰带所面对的方向相同？

A只是一个规则，所有部分都有一个表示它们在三维世界空间中的位置和方向的A。它们都有一个指向其前进方向的LookVector

如果要将腰带添加到角色模型，我建议在模型中使用零件，并使用其CFrame作为起点，然后相应地对其进行偏移

例如：

-- access the character model in the workspace
game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAppearanceLoaded:Connect(function(character)

        -- DEBUG : wait for player to stop falling
        wait(2)
        
        -- choose a starting point
        local hips = character:WaitForChild("LowerTorso", 10)
        
        -- create a belt
        local belt = Instance.new("Part")
        belt.Name = "Belt"
        belt.Size = Vector3.new(2,1,2)
        
        -- position the belt on the player's character
        -- NOTE - EXPERIMENT WITH CHANGING THESE VALUES TO ADJUST THE POSITION AND ROTATION
        local positionOffset = CFrame.new(Vector3.new(0, 0, 0))
        local rotationOffset = CFrame.Angles(math.rad(0), math.rad(0), math.rad(0))
        belt.CFrame = hips.CFrame * positionOffset * rotationOffset
        
        -- weld the belt to the player
        local weld = Instance.new("WeldConstraint", belt)
        weld.Part0 = belt
        weld.Part1 = hips
        
        -- DEBUG : color the front of belt to make sure that it is oriented correctly
        local surface = Instance.new("SurfaceGui", belt)
        surface.Adornee = belt
        surface.Face = Enum.NormalId.Front
        local frame = Instance.new("Frame", surface)
        frame.Size = UDim2.fromScale(1, 1)
        frame.Position = UDim2.fromScale(0, 0)
        frame.BackgroundColor3 = Color3.new(0, 0, 1)
        
        -- put the belt into the world
        belt.Parent = character
    end)
end)
