How do I move the camera relative to the direction it's facing?

I'm making a freecam script that moves with WASD, everything works fine but the MoveCamera function in my script is only made to move relative to the world space, I want to make the camera move relative to where the camera is looking at (just like how studio camera mouvements are based on where you look at). But the problem with that is I don't know how to make the camera move relative to where it's looking at so that's why I came here for help, I would really appreciate it if someone would help me with this :slight_smile: anyways here is the function that controls how my camera move each time you hold a key moves:

        local function MoveCamera(x,y,z,positive)
            --print("Move!")
            x = x > 0 and x + FCspeed or 0
            y = y > 0 and x + FCspeed or 0
            z = z > 0 and x + FCspeed or 0
            
            local CameraPos = Camera.CFrame.p
            local MoveVector = Vector3.new(x,y,z)
            local Directionvector = Camera.CFrame + MoveVector
            local CF = positive == false and Camera.CFrame - MoveVector or Camera.CFrame + MoveVector
            
            
            Camera.CFrame = CF
            FCspeed = FCspeed + 0.001
            FCspeed = math.clamp(FCspeed, 0.001, 0.5)
            LastMouvementCall = tick()
            
            SERVICES.RUN_SERVICE.RenderStepped:Wait()
        end

And here is the full script:

local FCspeed,LastMouvementCall = 0.001 ,tick()
	local function FreecamControl(_,State,InputINFO)
		
		local function MoveCamera(x,y,z,positive)
			--print("Move!")
			x = x > 0 and x + FCspeed or 0
			y = y > 0 and x + FCspeed or 0
			z = z > 0 and x + FCspeed or 0
			
			local CameraPos = Camera.CFrame.p
			local MoveVector = Vector3.new(x,y,z)
			local Directionvector = Camera.CFrame + MoveVector
			local CF = positive == false and Camera.CFrame - MoveVector or Camera.CFrame + MoveVector
			
			
			Camera.CFrame = CF
			FCspeed = FCspeed + 0.001
			FCspeed = math.clamp(FCspeed, 0.001, 0.5)
			LastMouvementCall = tick()
			
			SERVICES.RUN_SERVICE.RenderStepped:Wait()
		end
		
		if InputINFO.KeyCode == Freecam_Controls.KEYBOARD.W then
			
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.W) do
				
				MoveCamera(0,0,.1,false)
			
			end
		elseif InputINFO.KeyCode == Freecam_Controls.KEYBOARD.A then
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.A) do
				
				MoveCamera(.075,0,0,false)
			end
			
		elseif InputINFO.KeyCode == Freecam_Controls.KEYBOARD.D then
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.D) do
				
				MoveCamera(.075,0,0,true)
			end
			
		elseif InputINFO.KeyCode == Freecam_Controls.KEYBOARD.S then
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.S) do
				
				MoveCamera(0,0,.075,true)
			end
			
		elseif InputINFO.KeyCode == Freecam_Controls.KEYBOARD.LIFT then
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.LIFT) do
				
				MoveCamera(0,.075,0,true)
			end
			
		elseif InputINFO.KeyCode == Freecam_Controls.KEYBOARD.DOWN then
			while SERVICES.USER_INPUT_SERVICE:IsKeyDown(Freecam_Controls.KEYBOARD.DOWN) do
				
				MoveCamera(0,.075,0,false)
			end
		end
	end
	
	local function HeartBeat()
		if PlayerState:lower() == "freecam" then
			
			if tick() - LastMouvementCall >= .1 and FCspeed > 0.001 then
				FCspeed = FCspeed - 0.001
				print(FCspeed)
			end
			
			Camera.CameraType = Enum.CameraType.Scriptable
			--print("eeee")
			SERVICES.CS:BindAction("Freecam_W", FreecamControl, false, Freecam_Controls.KEYBOARD.W)
			SERVICES.CS:BindAction("Freecam_A", FreecamControl, false, Freecam_Controls.KEYBOARD.A)
			SERVICES.CS:BindAction("Freecam_D", FreecamControl, false, Freecam_Controls.KEYBOARD.D)
			SERVICES.CS:BindAction("Freecam_S", FreecamControl, false, Freecam_Controls.KEYBOARD.S)
			SERVICES.CS:BindAction("Freecam_^", FreecamControl, false, Freecam_Controls.KEYBOARD.LIFT)
			SERVICES.CS:BindAction("Freecam_|", FreecamControl, false, Freecam_Controls.KEYBOARD.DOWN)
		else
			SERVICES.CS:UnbindAction("Freecam_W")
			SERVICES.CS:UnbindAction("Freecam_A")
			SERVICES.CS:UnbindAction("Freecam_D")
			SERVICES.CS:UnbindAction("Freecam_S")
			SERVICES.CS:UnbindAction("Freecam_^")
			SERVICES.CS:UnbindAction("Freecam_|")
		end
		
	end

Try using LookVector.
