Strict Lerp rotation?

Unity Engine

Hey all, I’m trying to simply have my player rotate 90 degrees, when I say so well when he hits certain objects. However, when the player rotates its never a precise 90 degrees. I can not figure this out, and it’s been a problem all weekend. :frowning:

Any ideas are really appreciated, I’ve scouted the docs most of this morning; this is my most recent attempt

    var Yangle :float;
    static var turnR : boolean = false;
    
    function Start(){
    Yangle = 0;
    }
    
    function Update () {
    
    transform.eulerAngles =Vector3(0,Yangle,0);
    var hit2 : RaycastHit;
    	if (Input.GetButton ("Jump")) {
    		if (Physics.Raycast (transform.position, -transform.right, hit2, 2.2)) {
    
    		   	if (hit2.collider.tag=="Turn2"){
    		   	Debug.Log("non");
    		   	turnright = true;
    			turnR = true;
    		}
    	if(turnR == true)
    	{
    		    TR();
    	}
    
    
    function TR(){
    		transform.localRotation = Quaternion.identity;
    		print(transform.localRotation.y);
    		var B : float = (Yangle -90);		
    		var angle : float = Mathf.LerpAngle(Yangle,B,1*Time.deltaTime);
    		transform.eulerAngles = Vector3(0, angle, 0);
    		Yangle =angle;
    		yield WaitForSeconds(1);
    		turnR = false;
    
    		}

I don’t think I’m too far off the final piece, but I’m lost now. I assume it’s something to do with time. Thank you in advance.

Still struggling with this one, any idea would be very much appreciated.
