The mass of the rigidbody.
Different Rigidbodies with large differences in mass can make the physics simulation unstable.
Higher mass objects push lower mass objects more when colliding. Think of a big truck, hitting a small car.
A common mistake is to assume that heavy objects fall faster than light ones.
This is not true as the speed is dependent on gravity and drag.
// Expose mass to allow adjustment from // the inspector.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public float mass; public Rigidbody rb;
void Start() { rb = GetComponent<Rigidbody>(); rb.mass = mass; } }
