how can I align player with slope normals(no rigidbody)

i really need to find out how to do this, ive read about raycasts and looked through answers, but none of them work. my character either rotated randomly or teleported. can someone make me a script?

Here is my char controller:

 public var walkSpeed : float = 1.0; private var gravity = 60; private var moveDirection : Vector3 = Vector3.zero; private var charController : CharacterController; //private var power : float = 4.0;
 public var JumpSpeed : float; 
 public var motor : CharacterMotor;
 public var acc : float;
 public var maxspeed : float;
 var underwater : boolean = false;
 public var motor2 : CharacterMotorJumping;
 function Start() { charController = GetComponent(CharacterController); animation.wrapMode = animation.wrapMode.Loop;
 targetNormal = transform.up;
  }
 public var pad : float = 0.0f;
 var jumpingFromPad : boolean = false;
 var canJumpFromPad : boolean = true;
 public var streak : GameObject; // player direction in X-Z space;
 public var energy : float;
 public var isGrounded : boolean = false;
 //Make raycast direction down
 public var homing : homingattack;
 private var vertVel: float = 0; // vertical velocity 
 function Awake () {
     motor = GetComponent(CharacterMotor);
 }
 function Update () {
     if(Input.GetKey("e") ) {      
          animation.CrossFade("Jump");
         }
     if(!isGrounded)
     {
         homing.canhome = true;
     }
     if (jumpingFromPad)
     {
         animation.CrossFade("Up");
     }
     if (canJumpFromPad && jumpingFromPad)
     {
             
             
             pad += Time.deltaTime;
             vertVel = 100;
 
     }
 
     if (pad >= 1.5f && jumpingFromPad)
             {
             pad = 0;
             jumpingFromPad = false;
             homing.canhome = true;
             }
     
     var distToGround: float;
     isGrounded = Physics.Raycast(transform.position, -Vector3.up, distToGround + 1.5);

     energy = 3;
     }
          if(Input.GetKey("e") ) {      
          animation.CrossFade("Jump");         
          animation["Jump"].speed = 20; 
          }
      
     if(Input.GetAxis("Vertical") > 0.1 && isGrounded) {
     if (charController.isGrounded)
     {
          if(Input.GetKey("left shift")) {
               animation["Run"].speed = 90;
          }
 
          else {
               animation.CrossFade("Run");
               animation["Run"].speed = 1;
          }
     }
     }
     else
