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

i really need to find out how to do t$$anonymous$$s, 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;
             }

     }

          }
      
     if(Input.GetAxis("Vertical") > 0.1 && isGrounded) {
     if (charController.isGrounded)
     {
          if(Input.GetKey("left s$$anonymous$$ft")) {
               animation["Run"].speed = 90;
          }
 
          else {
               animation.CrossFade("Run");
