Problem with moving player relative to camera

Questions & Answers
1

Hi, I’m trying to achieve movement so that player can move up, down, right and left, but the character only rotates to match the sideways movement. (Similar to old beat-em up games like Battletoads and Double Dragon). The problem I have is when pressing the key A (moving left) the character moves to right instead of left. Every other direction works fine.

I have it setup like this: the character has a character controller inside it. Camera is a child of the player so it follows around. I’m processing input with a modified code based on this : http://unity3d.com/support/documentation/ScriptReference/CharacterController.Move.html and here’s my code:

    void Update() 
{
	CharacterController controller = GetComponent<CharacterController>(); 
	if (controller.isGrounded) 	
		{
			
		moveDirection = new Vector3(Input.GetAxis("Vertical"), 0, -Input.GetAxis("Horizontal"));
		
		moveDirection = transform.TransformDirection(moveDirection);
		moveDirection *= speed;
			
			if(Input.GetKey("a")){
				transform.rotation = Quaternion.Euler(0, 270, 0);
				
			}
			if(Input.GetKey("d")){
				transform.rotation = Quaternion.Euler(0, 90, 0);	
			}
		}
		
	controller.Move(moveDirection * Time.deltaTime);
		Debug.Log(moveDirection);
    }

Rotating the player obviously causes the problem here, as it flips the local axis around, but if I have understood right, using transform.TransformDirection should move the player in world space(?)… I have been stuck with this problem for a while now so any help is greatly appreciated!

You could make the graphic a child element. Then when you push a, just rotate the child (just the graphic) and move the character separately.

myGraphicGameObject.transform.rotation = Quaternion.Euler(0, 270, 0);
