How to tell which direction I'm moving in

Help and Feedback Scripting Support
#1

I am currently looking for a way to tell which way I am moving. However, the solutions i have tried (like Humanoid.MoveDirection) all don’t achieve what I need. What I need is data in a Vector3 that tells me if my player character is moving left, right, back, or forward. Does this data exist? If not, how would I code it into existence? Thanks!

try this “Humanoid.RootPart.AssemblyLinearVelocity.Unit”

You will get the Unit Vector (Vector3) move direction of the player

#3

It should? It returns exactly what you want.

#4

You should combine Humanoid.MoveDirection with the direction that the character is facing to find out the relative motion of the player. If you need an example, let me know.

#5

I think they are looking for the relative direction, not the absolute direction.

#6

Try MoveDirection along with this.

function cardinalConvert(dir)
	local angle = math.atan2(dir.X, -dir.Z)
	local quarterTurn = math.pi / 2
	angle = -math.round(angle / quarterTurn) * quarterTurn
	
	local newX = -math.sin(angle)
	local newZ = -math.cos(angle)
	if math.abs(newX) <= 1e-10 then newX = 0 end
	if math.abs(newZ) <= 1e-10 then newZ = 0 end
	return Vector3.new(newX, 0, newZ)
end

This is ALMOST exactly what I need, but it shows the same problem I’m having. For detail, my problem is that, for example, facing left and walking left (A key) produces, let’s say a 1. But turning around to face right and walking left (A key) would produce a -1. I want a way to know if I’m pressing A, D, W, S, etc. all in a neat Vector3 value.

Maybe focus on the last key they pushed. Idk, not all movement will totally show direction.

I think I understand what you need. You can get the raw input moveVector by calling the ControlModule:GetMoveVector(). This function can be found in PlayerModule.ControlModule

-- Convenience function so that calling code does not have to first get the activeController
-- and then call GetMoveVector on it. When there is no active controller, this function returns the
-- zero vector
function ControlModule:GetMoveVector(): Vector3
   if self.activeController then
         return self.activeController:GetMoveVector()
   end
   return Vector3.new(0,0,0)
end

Make a copy of the PlayerModule during runtime and paste it back into StarterPlayerScripts ,
then from there you can access the roblox default ControlModule by requiring the module.
