Help and Feedback Scripting Support
#1

I am making a flying script and I want the character to face the same way that the camera is looking at

the issue is that when I am using the normal solution, CFrame.lookAt my character stars going towards the camera for some reasons
https://gyazo.com/e333a35f1ba4e1463c1fea1d4a270331

I have seen a forum post that does half of what I want, it does not rotate the character on the X rotation
the lines are

local CameraRotation = math.atan2(-cam.CFrame.lookVector.X, -cam.CFrame.lookVector.Z)
		Character.HumanoidRootPart.CFrame = CFrame.new(Character.HumanoidRootPart.CFrame.Position) * CFrame.Angles(0, CameraRotation, 0)

this is my full code

local player = game.Players.LocalPlayer
local Character = script.Parent
local Humanoid = Character:FindFirstChild("Humanoid")

local cam = workspace.CurrentCamera
local UserInputService = game:GetService("UserInputService")

local idleAnim = Character:WaitForChild("Humanoid"):LoadAnimation(script:WaitForChild("FlyIdle"))
local forwardAnim = Character:WaitForChild("Humanoid"):LoadAnimation(script:WaitForChild("FlyForward"))

local flying = false
local canFly = false

Humanoid.StateChanged:connect(function(old, new)
	if new == Enum.HumanoidStateType.Freefall then
		canFly = true
	elseif new == Enum.HumanoidStateType.Landed then
		canFly = false
	end
end)

UserInputService.InputBegan:Connect(function(key, chat)
	if chat then return end

	if key.KeyCode == Enum.KeyCode.Space and (canFly or flying) then
		if not Character or not Humanoid or not Character:IsDescendantOf(workspace) or
			Humanoid:GetState() == Enum.HumanoidStateType.Dead then
			return
		end
		
		print("Pro")
		
		if flying then
			Character.Animate.Disabled = false
			idleAnim:Stop()
			forwardAnim:Stop()
			Character.PrimaryPart:FindFirstChild("FlightForce"):Destroy()
		elseif not flying then
			Character.Animate.Disabled = true
			for i,v in ipairs(Humanoid:GetPlayingAnimationTracks()) do
				if tostring(v.Name) == "FallAnim" or tostring(v.Name) == "JumpAnim" then
					v:Stop()
				end
			end
			idleAnim:Play()

			local bv = Instance.new("BodyVelocity")
			bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
			bv.Velocity = Vector3.new(0,0,0)			
			bv.Name = "FlightForce"
			bv.Parent = Character.PrimaryPart
			
			Character.HumanoidRootPart.CFrame = CFrame.new(Character.HumanoidRootPart.Position, Character.HumanoidRootPart.Position +  cam.CFrame.LookVector)
		end
		flying = not flying
	end
end)

game:GetService("RunService").RenderStepped:Connect(function()
	if flying then
		print(flying)
		local CameraRotation = math.atan2(-cam.CFrame.lookVector.X, -cam.CFrame.lookVector.Z)
		Character.HumanoidRootPart.CFrame = CFrame.new(Character.HumanoidRootPart.CFrame.Position) * CFrame.Angles(0, CameraRotation, 0)
		
		Character.PrimaryPart:FindFirstChild("FlightForce").Velocity = Vector3.new(0,0,0)
		forwardAnim:Stop()
		
		local movez = 0
		local movex = 0
		local moveUP = 0
		
		if UserInputService:IsKeyDown(Enum.KeyCode.W) then
			movez += 60
		end
		if UserInputService:IsKeyDown(Enum.KeyCode.A) then
			movex -= 60
		end		
		if UserInputService:IsKeyDown(Enum.KeyCode.S) then
			movez -= 60
		end	
		if UserInputService:IsKeyDown(Enum.KeyCode.D) then
			movex += 60
		end
		if UserInputService:IsKeyDown(Enum.KeyCode.E) then
			moveUP += 40
			movez += 40
		end
		if UserInputService:IsKeyDown(Enum.KeyCode.Q) then
			moveUP -= 40
			movez -= 40
		end
		Character.PrimaryPart:FindFirstChild("FlightForce").Velocity = Character.HumanoidRootPart.CFrame.lookVector * movez + Character.HumanoidRootPart.CFrame.rightVector * movex + Character.HumanoidRootPart.CFrame.UpVector * moveUP

	end
end)

in starter character scripts

I am trying to make it rotate the x to the correct direction.

I’m assuming the rest of the code is ok, try enabling humanoid.PlatformStand. The humanoid may be trying to getup and exert force to stand up hence cause the weird behavior.

UserInputService.InputBegan:Connect(function(key, chat)

		if flying then
Humanoid.PlatformStand = true

oh my god, I’ve been searching for days for this solution and it worked.
I did not know it was that easy.
