Set World Gravity Using Gyroscope (2D)

Unity Engine
1

I would like to set the world gravity based on the Gyroscope, so if someone rotates their device the gravity changes as well.

I assume this is a fairly easy task, but I am not sure how to do it, and I can’t seem to find anything on Google about it either.

Any help on this is appreciated!

I have never used the accelometer but I am sure, you could relate a tilt angle to an applied force.

I am not sure what you mean… could you please explain? Thanks!

I would think it would be something like this…

Physics2D.gravity = Input.gyro.attitude.eulerAngles;

Something like that. You would have to test.

From what I am reading, it looks like have to use Input.acceleration to get the rotation. But still don’t know how to set gravity…

There we go! I got it working!

public class Main : MonoBehaviour {
  
    // Update is called once per frame
    void FixedUpdate(){
        if(Application.platform == RuntimePlatform.Android){
            float gx = Input.acceleration.x * 9.81f;
            float gy = Input.acceleration.y * 9.81f;
            Physics2D.gravity = new Vector2(gx, gy);
        }
    }
}
