Face Direction of Tilting

Questions & Answers
1

I’m currently working on a 2D game where the player can move along the x and y axis based on the accelerometer. I’m currently using this to get that done:

Vector3 dir = Vector3.zero;
        dir.x = Input.acceleration.x;
        dir.y = Input.acceleration.y;
        if (dir.sqrMagnitude > 1)
        {
            dir.Normalize();
        }

        dir *= Time.deltaTime;
        transform.Translate(dir * speed);

What I am trying to figure out next is how to get the player to face the direction it’s tilting towards (z axis for rotation). Googled up many result but I can’t seem to find a solution.

I think this will do what you want:

float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
transform.eulerAngles = new Vector3(0,0,angle);

This will face the right side towards ‘dir’. If you need another side, add or subtract 90x to the angle before creating the vector.
