how to find way of rotation

Question

how do i track the way the character rotates. and what speed it rotates in. like i wanna track if it goes up down left or right,how do i track my rotation so that it knows what way it goes. i tried but i couldnt do it without anything else then the position value

I don't know your code or if your game is 3D or 2D but to find the direction it could be just:

      if (transform.eulerAngles.z == 0) //Up (or you can setup bounds for the rotation – example: if (transform.eulerAngles.z > 350 && transform.eulerAngles.z < 10))
     {

     }

     if (transform.eulerAngles.z == 90) //Right – example: if (transform.eulerAngles.z > 80 && transform.eulerAngles.z < 100))
     {

     }

     if (transform.eulerAngles.z == 180) //Down
     {

     }

     if (transform.eulerAngles.z == 270) //left
     {

     }

For determining the rotation speed, you can try this in void Update():

 rotationSpeed = transform.eulerAngles.z - previousRotation;
 previousRotation = transform.eulerAngles.z;

And this in void Start():

 previousRotation = transform.eulerAngles.z;

but how could this work on others than the standard rotation

Try creating a coroutine with a delay yield return new WaitForFixedUpdate(); and make it self-invoking. Each call write the value of transform.Rotation to a local variable and check what it was before. So you can calculate the speed and direction

Quaternion _lastRotation = transform.rotation;
