Sets the mass based on the attached colliders assuming a constant density.

This is useful to set the mass to a value which scales with the size of the colliders.

	rigidbody.SetDensity(1.5);

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    void Example() {
        rigidbody.SetDensity(1.5F);
    }
}

import UnityEngine
import System.Collections

public class Example(MonoBehaviour):

	def Example() as void:
		rigidbody.SetDensity(1.5F)
