accelerometer speed

Questions & Answers

Hey guys I was looking at the accelerometer tutorial that Unity made.

I’ve been trying to understand how to limit the speed. Right now it shoots off at a thousand miles per hour if I tilt it more than a centimeter.

There’s no much to look at, but I’m only wanting to use the accelerometer for the X axis.

Here is the basic code that I have.

public class Controls : MonoBehaviour {

	// Variables dealing with Speed and boost.

	public float speed;
	public int sideSpeed = 1.0;



	void Start(){

	}

	// Update is called once per frame
	void Update () {
		//Use this for constant forward movement
		transform.Translate (Vector3.forward * speed * Time.deltaTime);
		//Use this for the accelerometer for X Axis.
        transform.Translate (Input.acceleration.x, 0, 0 * sideSpeed * Time.deltaTime);

	}


}

I’ve tried doing it with Addforce, but even if I change the force to 50000 it just moves in slowmotion.

I’ve seen stuff about clamps, but I don’t understand the clamping for this.
I’m new to mobile development.

Please help me.

Thank you!

Use a rigidbody with addforce in a FixedUpdate() function instead of the Upate function.

Mathf.Clamp(float value, float min, float max) just returns a value between 2 given, if the value is lower than the min, the value will be min, if it’s higher than max, it’ll be max. for example:

float value = Mathf.Clamp(10, 2, 3);// value will be 3, because 10 is bigger than 3.
float value = Mathf.Clamp(10, 20, 30);// value will be 20, because 10 is smaller than 20.

as for the rigidbody, it should look something like this:

void FixedUpate()
{
    Vector3 force = new Vector3(Input.acceleration.x, 0, 0) * sideSpeed;
    rigidbody.AddForce(force);
}
