How do I edit my code to make it work for 2d game?

Question

I found this code online:

Right now it works well except it rotates the x axis which ruins my 3d effect. How can I keep the x axis and y axis at 0 rotation?

var accel = 0.8; var inertia = 0.9; var speedLimit = 10.0; var minSpeed = 1.0; var stopTime = 1.0;

private var currentSpeed = 0.0;

private var functionState = 0; 
private var accelState : boolean; 
private var slowState : boolean;

private var waypoint : Transform; 
var rotationDamping = 6.0; 
var smoothRotation = true; 
var waypoints : Transform[]; 
private var WPindexPointer : int;

function Start () 
{ 
   functionState = 0;     
}

function Update () 
{ 
   if (functionState == 0) 
   { 
      Accell (); 
   } 
   if (functionState == 1) 
   { 
      Slow (); 
   } 
   waypoint = waypoints[WPindexPointer]; 
}

function Accell () 
{ 
   if (accelState == false) 
   {                 
      accelState = true;  
      slowState = false;  
   }                 
   if (waypoint) 
   { 
      if (smoothRotation) 
      { 
         var rotation = Quaternion.LookRotation(waypoint.position - transform.position); 
         transform.rotation = Quaternion.Slerp(transform.rotation, rotation,Time.deltaTime  rotationDamping); 
      } 
   } 
currentSpeed = currentSpeed + accel  accel; 
              transform.Translate (0,0,Time.deltaTime * currentSpeed);

   if (currentSpeed >= speedLimit) 
   { 
      currentSpeed = speedLimit; 
   } 
}

function OnTriggerEnter () 
{ 
   functionState = 1; 
   WPindexPointer++;

   if (WPindexPointer >= waypoints.Length) 
   { 
      WPindexPointer = 0; 
   } 
}

function Slow () 
{ 
   if (slowState == false) 
   {                 
      accelState = false; 
      slowState = true;  
   }

    currentSpeed = currentSpeed * inertia; 
    transform.Translate (0,0,Time.deltaTime * currentSpeed);

   if (currentSpeed <= minSpeed) 
      { 
      currentSpeed = 0.0; 
      yield WaitForSeconds (stopTime); 
      functionState = 0; 
   } 
}

At the end of Update, or in LateUpdate:

transform.eulerAngles = new Vector3(0, 0, transform.eulerAngles.z);

Or whatever angles you want to have set at 0.

is there anymore efficient ways? cuz then it gets called alot. any ways to like set it once and it works?

also which one tells what number to set the axis to? cuz i want to change that value. Thanks.

What? Everything in Update "gets called a lot". One line is about as efficient as it gets. And it's X, Y, Z, the same as every other Transform function in Unity.
