Movement inverts when changing direction

[hanaharu7]

Hello!

Having an annoying issue when moving my player around a scene. When facing right the up and down buttons work as they should, but when I face left the up and down buttons are inverted.

	void movement ()
	
	{

		position = transform.TransformDirection(Vector3.right)*speed;

		if(Input.GetKey(KeyCode.LeftArrow))
		{
			transform.eulerAngles = new Vector3(0,180);
			FacingRight= false;
			{
				controller.Move(position * Time.deltaTime);
			}
		}
		if (Input.GetKey (KeyCode.RightArrow)) 
		{
			transform.eulerAngles = new Vector3 (0,0);
			FacingRight = true;
			{
				controller.Move (position * Time.deltaTime);
			}
		}
		if (Input.GetKey (KeyCode.DownArrow))
		{
			controller.Move(-transform.forward * speed * Time.deltaTime);

		}
		if (Input.GetKey (KeyCode.UpArrow)) 
		{
			controller.Move(transform.forward * speed * Time.deltaTime);

		}
	}

I tried using transform.Translate instead of controller.Move for the up and down arrows. While it did move correctly, It caused the player to move through objects/ colliders didn’t interact with the object.

Any help would be greatly appreciated

Is this 2D or 3D? Because with this code you limit your movement to one axis. Try this for 3D movement on a plane:

     void movement ()
     
     {
         float turnspeed = 30.0f; //play with this value
         
         if(Input.GetKey(KeyCode.LeftArrow))
         {
             FacingRight = false;
             transform.rotation *= Quaternion.AngleAxis(turnspeed*Time.deltaTime,Vector3.up);
         }
         if (Input.GetKey (KeyCode.RightArrow)) 
         {
             FacingRight = true;
             transform.rotation *= Quaternion.AngleAxis(-turnspeed*Time.deltaTime,Vector3.up);
         }
         if (Input.GetKey (KeyCode.DownArrow))
         {
             controller.Move(-transform.forward * speed * Time.deltaTime);
 
         }
         if (Input.GetKey (KeyCode.UpArrow)) 
         {
             controller.Move(transform.forward * speed * Time.deltaTime);
 
         }
     }

If left and right are wrong, swap the minus from the turnspeed.
