How do I resume the rotation where it last rotates when it got pause?

Question

public class PlayerControl : MonoBehaviour
{
    float Speed = 125f;
    void FixedUpdate()
    {
        transform.Rotate(0, 0, Speed * Time.deltaTime);
    }

    public void ChangeDirection()
    {
        Speed = -Speed;
    }

    public void PauseMovement() <---- Pointer Down
    {
        Speed = 0f;
    }

    public void Boost()
    {
        Speed = 330f * Mathf.Sign(Speed);
    }

    public void NormalSpeed()   <----- Pointer Up
    {
        Speed = 125f * Mathf.Sign(Speed);
    }

}

I press a button on a trigger event as pointer down, my player stops moving and when i release the button, it resumes as per normal. This works but not as how i intended, when i want my player to resume, i want it to resume the direction it last went. Like if it rotates to the left, it will continue on the left. Right now, it last rotates on the left, it continues on the right. Please advice?

Answer 1

First I will define a bool:

private bool IsClockwise; // set it to true or false depending on your need

And then making the Speed variable non-negative:

    float Speed = 125f;
    void FixedUpdate()
    {
        transform.Rotate(0, 0, Speed * Time.deltaTime);
    }

    public void ChangeDirection()
    {
        // We don't change the value of Speed here!
    }

    public void PauseMovement() <---- Pointer Down
    {
        Speed = 0f;
    }

    public void Boost()
    {
        Speed = 330f;
    }

    public void NormalSpeed()   <----- Pointer Up
    {
        Speed = 125f;
    }

And finally, let's define the new ChangeDirection method:

public void ChangeDirection()
{
    IsClockwise = !IsClockwise;
}

But it won't affect anything before we tweak the rotation part:

void FixedUpdate()
{
    if (IsClockwise)
        transform.Rotate(0, 0, Speed * Time.fixedDeltaTime);
    else
        transform.Rotate(0, 0, -Speed * Time.fixedDeltaTime);
}

Note that as you want to do this in FixedUpdate, you will need to use fixedDeltaTime instead of deltaTime (see Unity's documentation)
