How to prevent camera pitch from affecting player movement vector?

[TemmieHQ (Guest 3692)]

What is my goal?
So I’m making a movement system and I have made a “wishdir” variable that outputs a vector3 depending on the players inputs. (i.e. if the player presses W, wishdir becomes 0, 0, -1 S it becomes 0, 0, 1 etc.) I’m working on making this vector3 relative to the player’s camera so movement is sensical.

The Issue:
My issue is that when the player moves their camera’s pitch, the wishdir moves with the camera. In the video provided you can visually see the wishdir as a blue line, and it’s relativity does work with horizontal camera changes. but I’d like to be able to nullify vertical changes without simply multiplying the Y of that vector by zero as I still want to be able to act on jump inputs (0, 1, 0)

What have I tried?
I’ve looked over the Devforum and haven’t found any solutions that don’t just multiply that Y value by 0.
If that is required, is there another way I can still include the jump input somehow?

My Code:
These are the important two lines that I think I have to add some math to somewhere but I’m not exactly sure where or how.

local camera = game.Workspace.CurrentCamera.CFrame -- grabs the Cframe of the player camera
 
	local newdir = camera:VectorToWorldSpace(wishdir) -- orients wishdir using camera and gives it to newdir

Any help would be greatly appreciated, thanks!

local CameraDirection = workspace.CurrentCamera.CFrame.LookVector

local moveDirection = Vector3.new(CameraDirection.X,0,CameraDirection.Z).Unit

You shouldn’t update your move direction for jumps, you should actually just change AssemblyLinearVelocity

[theseformasentence (kaziel)]

You shouldn’t update move direction for jumping, because move direction applies speed at a consistent rate, and if you want reactive jumping, you cant use something like a VectorForce because that accelerates, you would have to accelerate up to 50, which takes time

[TemmieHQ (Guest 3692)]

That makes a lot of sense. Right now I’m using a LinearVelocity to move the character, would you recommend just using AssemblyLinearVelocity control all movement for this type of system?

[theseformasentence (kaziel)]

No. LinearVelocity for movement is fine, lots of games actually use acceleration for walking, but they set the velocity for jumping

[TemmieHQ (Guest 3692)]

Alright, thanks for the advice! I’m gonna start working on implementing this now.

The humanoid actually has a MoveDirection property that does the same thing I did
