刚体的质量。
质量差异较大的不同刚体会使物理模拟不稳定。
发生碰撞时,质量较大的对象对质量较小的对象的推力要更大一些。您可以想象一下大卡车与小汽车相撞的场景。
一个常见的错误是假设重物的下落速度比较轻的物体快。
事实并非如此,下落速度实际上取决于重力和阻力。
// 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; } }
