Constant force

Hey guys i was just wondering how to change the constant force gravity on an object on collision

var hit = false;
function OnCollisionEnter(collider : Collision)
{
hit = true;
}
function Update()
{
if(hit)
{
rigidbody.AddForce(transform.forward * 10 * Time.deltaTime)
}

}

There are two ways to change the gravity affecting an object:

You can change the Physics.gravity constant to affect all objects or you can add gravity by hand

Editing Physics.gravity is simple (see the doc link) but affects EVERYTHING

To apply a diffrent gravity to this object, have a script that does the following:

  • rigidbody.useGravity = false;
  • Holds a var localGrav : Vector3 = Vector3.up * -9.8;//down 9.8 m/(s*s) is earth's gravity
  • Inside of LateUpdate,
  • [rigidbody.AddForce][3]( localGrav, [ForceMode][4].Acceleration );

Now just change localGrav and your rigidbody will move at a localized, custom gravity amount
