Rotating a character smoothly around 90 degrees

Questions & Answers
1

Hi I’m working on my first game, a top down 2D game. I need the player to rotate smoothly 90 degrees around the local y axis over half a second. At the moment I am using

GameObject.Find("Player").transform.Rotate(Vector3(0, 90, 0));

which rotates the character fine, but instantly rather than smoothly over around half a second as I need it to. I have tried using Time.deltaTime but when used the character rotates a small amount rather than the full 90 degrees.

Here’s all I have so far

private var canMove : boolean;

function Start () {
canMove = true;
}

function Update () {
 if(canMove){
  if(Input.GetKeyDown("left")){
   TurnLeft();
  }
  if(Input.GetKeyDown("right")){
   TurnRight();
  }
 }
}

function TurnLeft () {
 GameObject.Find("Player").transform.Rotate(Vector3(0, 90, 0));
}

function TurnRight () {
 GameObject.Find("Player").transform.Rotate(Vector3(0, -90, 0));
}

This might be completely wrong but I am extremely new to coding still. Hope you can help.

Try this :

private var canMove : boolean;

private var turnLeft : boolean;

private var turnRight : boolean;

private var rotationVal : float = 0f;

private var temp : float =  0f;

private var myTransform;

function Start () {
canMove = true;
myTransform = GameObject.Find("Player").transform;
}

function Update () {
 if(canMove){
  if(Input.GetKeyDown("left")){
     turnLeft = true;
   //TurnLeft();
  }
  if(Input.GetKeyDown("right")){
    turnRight = true;
   //TurnRight();
  }
 }
}

function LateUpdate()
{
    if(turnLeft)
    {
	     if(temp > 90){
	   		turnLeft = false;
	    	temp = 0f;
	     }
	     else{
		       rotationVal = Mathf.Lerp(0f,90f,Time.deltaTime);
		       myTransform .Rotate(Vector3(0, rotationVal, 0));
		       temp += rotationVal;
	      }
        
    }
    else if(turnRight)
    {
	    if(temp < -90){
	   		turnRight = false;
	    	temp = 0f;
	     }
	     else{
		       rotationVal = Mathf.Lerp(0f,-90f,Time.deltaTime);
		       myTransform .Rotate(Vector3(0, rotationVal, 0));
		       temp += rotationVal;
	      }
        
    }
}

Hope This will work for you…it’s works for me…

transform.Rotate(new Vector3(0, rotSpeed * Time.deltaTime, 0));
