# Help on a basic script

Hello. I’m fairly new to Unity, and I’m trying to make a simple barebone Android puzzle game. It’s a ball, which when you tilt, moves, and then puzzles and yada-yada-yadi-yada.
So far I have this script on the ball: (a modification of the Unity script)
#pragma strict
// Credit to Unity for this script

``````	// Move object using accelerometer
var speed = 10000.0;

function Update () {
var dir : Vector3 = Vector3.zero;

// we assume that device is held parallel to the ground
// and Home button is in the right hand

// remap device acceleration axis to game coordinates:
//  1) XY plane of the device is mapped onto XZ plane
//  2) rotated 90 degrees around Y axis
dir.x = Input.acceleration.x * 5;
dir.z = Input.acceleration.y * 5;

// clamp acceleration vector to unit sphere

// Make it move 10 meters per second instead of 10 meters per frame...
dir *= Time.deltaTime;

// Move object

}
``````

I’d like to add dampening or something similar, because currently this ball is in constant motion and that doesent allow for the player to have time to think. I’m also a bit confused about the speed, whatever I change it to it doesent change the actual speed. I made it add the force two times because that puts it at a semi-desirable level. I’d love any help.

Thanks.

For a better simulation, why don’t you just modify gravity to mimic the real world.

First, create a floor(and maybe some walls) for the ball to sit on and set its:

``````Rigidbody.useGravity = false;
Rigidbody.constraints = RigidbodyConstraints.FreezeAll;
``````

Then add gravity based on acceleration:

``````void Update()
{
Physics.gravity = new Vector3(Input.acceleration.x * 5, 0, Input.acceleration.y * 5);
}
``````

Lastly, Modify the PhysicMaterials and masses of the ground and ball for the desired effect.
