Look towards Running Direction

Question

so far i have this, but i'm really messed up with making my character face at the direction he's moving

 var speed: float=6.0;

var jumpSpeed: float=8.0; var gravity : float=20.0; private var tr : int =90; private var moveDirection : Vector3 = Vector3.zero;

function Update () { var controller : CharacterController = GetComponent(CharacterController); if(controller.isGrounded) { moveDirection = new Vector3(0,0,Input.GetAxis("Horizontal")); moveDirection = transform.TransformDirection(moveDirection); moveDirection *= speed;

     if(Input.GetButton("Jump"))
     {
     moveDirection.y = jumpSpeed;
     }
 }
 
 moveDirection.y -= gravity * Time.deltaTime;
 
 controller.Move(moveDirection * Time.deltaTime);

}

here you have it: Transform.LookAt

Your code could look like this:

 gameObject.transform.LookAt(gameObject.transform.position + moveDirection);

That is the easiest way I found to achieve what you want. Just be carefull that the rotation can be 'jumpy' at times (eg when you stop).

Thanks!! he can now face the direction but now, i'm having trouble moving him on the direction he's facing. it's like press "d" to move and then "a" to turn.

i'm making a 2d platformer game, Sorry about the lack of information on my post.

ok, then simply leave out the transform.TransformDirection. that way it should always go in the absolute direction you are giving it.

transformDirection tries to transform the vector you give it from local to global space. but since you want your input to give a global direction (one that isn't dependent on the current character orientation) thats the wrong thing to do.

did that clear things up?

For 2D, you're always looking left or right? In that case:

 if(MoveDirection.x<0)
   transform.rotation = Quaternion.Euler(0,-90,0);
 else
   transform.rotation = Quaternion.Euler(0,90,0);

There's no way to say "facing right," since it depends on the exact model. This assumes the model is facing "forwards" -- the most common way -- which would have her back to you. (0,90,0) is spun 90 degrees right. You may have to play with the numbers.

you are right, your solution is simpler then $$anonymous$$e but this does not help him with the problem he is facing with my solution.

his direction will still depend on the local rotation of his character and therefore end up completely weird for a 2d platformer.

thanks guys so far ive come up with both your ideas and made this, but i'm having trouble animating it.

 function FixedUpdate ()

{ if(grounded){ moveDirection = new Vector3(Input.GetAxis("Horizontal"),0,0); moveDirection*=speed;

         if(Input.GetButton("Jump"))
         {
         moveDirection.y=jumpSpeed;
     
         }
     }
 
 else
 {    
     moveDirection = new Vector3(Input.GetAxis("Horizontal"),moveDirection.y/speed,0);
     moveDirection*=speed;
 }
 
 
 moveDirection.y-=gravity*Time.deltaTime;
 
 controller = GetComponent(CharacterController);
 flags = controller.Move(moveDirection*Time.deltaTime*speed);
 
 grounded = (flags & CollisionFlags.CollidedBelow) !=0;
 
 
 
 if(moveDirection.x>0)
 {
 tr = 90;
 }else
 if(moveDirection.x<0){
 tr=270;
 }
 transform.eulerAngles.y-=(transform.eulerAngles.y-tr)/5;
 
 if(Input.GetAxis("Horizontal"))
 {
 animation.CrossFade("MRUN",0.3);
 }
 else
 {
 animation.CrossFade("MIDLE",0.3);
 }

}

"MWALK" layer is set to -1; "MIDLE" also

"MJUMP" layer is set to 10 which im having trouble animating him to jump;
