title: Unity: Changing direction character faces when using InputManager(side scroller)
body: <p>I'm creating a simple side scroller with a couple people using Unity and am definitely a beginner. The character being used is 3D and runs forward well, but when running backwards he still faces forward. I have the controls setup in the InputManager so pressing A moves backwards and D moves forward but I'm not sure what to do so he faces his respective movement. </p>
  
  <p>Any help would be greatly appreciated and if you need more information besides the following code I have for the movement let me know, it's based off another post I found.</p>
  
  <pre><code>var speed : float = 6.0;
  var jumpSpeed : float = 6.0;
  var gravity : float = 12.0;
  
  //This variable is now inheriting the Vector3 info (X,Y,Z) and setting them to 0.
  private var moveDirection : Vector3 = Vector3.zero;
  
  function MoveAndJump() {
  
      var controller : CharacterController = GetComponent(CharacterController);
  
      if(controller.isGrounded) {           
          //moveDirection is inheriting Vector3 info.  This now sets the X and Z coords to receive the input set to "Horizontal" and "Vertical"
          moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); //Allows player Input
          moveDirection = transform.TransformDirection(moveDirection);    //How to move
          moveDirection *= speed;     //How fast to move
  
          if(Input.GetButtonDown("Jump")) {
              animation.Play("Jump");
              moveDirection.y = jumpSpeed;
          }
      }
  
      //Apply gravity
      moveDirection.y -= gravity * Time.deltaTime;
  
      //This moves the controller
      controller.Move(moveDirection * Time.deltaTime);
  
      if(Input.GetButton("Fire1")){
          animation.Play("Attack");
      } 
  
      if(Input.GetButton("Vertical")){
          animation.Play("Run"); 
      }     
  }
  
  function Update() {     
      MoveAndJump();     
  }
  </code></pre>
  
  <p>For what it's worth another problem I'm having involves having two different animations being able to work at the same time, like run and attack. I figured I should mention while I'm here if anybody knew how to go about that. Thank you again for your time!</p>
