contacts | 用于获取这些结果的 ContactPoint 数组。 |
int
返回放置在 contacts
数组中的接触数。
检索该碰撞的所有接触点。
当检索接触点时,应确保提供的数组足够大,能够包含您感兴趣的所有接触点。该数组一般会重用,因此其大小应能够返回合理数量的接触点。此函数还意味着不发生分配,因此不需要垃圾回收器进行回收。
可以使用 contactCount 查看可用的接触点数。
另请参阅:contactCount。
contacts | 用于接收结果的 ContactPoint 列表。 |
int
返回放置在 contacts
列表中的接触点数。
检索该碰撞的所有接触点。
获取接触点时,尽量使所提供的列表足以包含所有需要的接触点。如果列表不够大,Unity 会自动将其大小增至可以包含所有接触点。列表通常会重复使用,因此,应该足够大以便返回合理数量的接触点。如果列表不必增加大小,则此函数不会分配任何内存,这意味着垃圾回收器不需要进行回收。
可以使用 contactCount 查看可用的接触点数。
另请参阅:contactCount。
