Can I use Cframe to move the player forward in the direction of the camera?

Basically what I am trying to do Is now that I have gotten rid of HumanoidController and I decided to start my own HumanoidController" but I do not know if it is possible to use Cframe when key == 'w' so that once the player does this it will move you forward in the camera direction using Cframe. I think this is possible but I do not know for sure. :/

Hope there is some explanation to this.

You can always use the Move method of Humanoid.

Move (Vector3 moveDirection, bool relativeToCamera)

The first argument is just the the Vector3, or 3D point in the place, or position you want your *humanoid *(player) to head towards until interrupted by the pressing of keys or a certain object

The second argument is set to false by default setting it to true would mean allowing the movement of the player to in relation or proportion to the Camera

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:wait()
local humanoid = character:WaitForChild('Humanoid')

humanoid:Move(Vector3.new(45, 0, 45), true)

Well,Im getting it that you want the player to move into the direction the camera is focusing on.

Well,A decent explenation is,Just make the camera move/focus on whatever brick you want,And then make another part that you want the player to walk to and use the :MoveTo() on the player's humanoid (MoveTo() to the position of the part you want the player to walk into),But be sure to disable the player's control or just while true do it and then break the code once the player is there.
