如何获得更准确/更灵敏的碰撞

Question

当我使用带有1个触发器的ontriggerenter时，一个固体对象进入（固体对象。沉入另一个固体对象。）另一个对象是刚体和碰撞对象

但是我需要使用oncolliderenter来立即获得点碰撞。不会像碰撞一样下沉。

我应该如何设置对象？哪个必须是刚体？ （顺便说一句，我不想​​使用重力，我现在正在使用动画。当球击中飞机时，球必须在点碰撞时触发动画）

Answer 1

摘自底部附近Colliders上的Unity3D的“手册”部分：

碰撞作用矩阵

两个对象发生碰撞时，根据碰撞对象的刚体的配置，可能会发生许多不同的脚本事件。下表提供了基于连接到对象的组件调用哪些事件函数的详细信息。某些组合只会使两个对象之一受到碰撞的影响，但是一般规则是，物理不会应用于没有附加刚体组件的对象。

发生碰撞检测并在发生碰撞时发送消息
