Unity3D中的碰撞检测

Question

我正在开发 3D 格斗游戏。我有两个角色和他们的动画。我已经应用了我自定义的角色控制器和角色控制器脚本。我有两个按钮，一个用于移动 farword，一个用于移动 backword..还有四个按钮来播放不同的动画，就像打一拳、打腿等。到目前为止，它的工作非常好。 现在我已经使用胶囊对象和他们的胶囊对撞机作为不同骨骼的孩子。就像我将一个胶囊对象与他们的对撞机放在左手骨头的孩子一样。所以骨头移动那个对象会移动.. 我还在第二个玩家身体上放置了一个胶囊，我将它放置在头部下方和腿部上方，这意味着它放置在胸部区域。我还使用了没有重力的刚体，并且在所有胶囊对象中单击了 onTrigger 函数。现在我希望当我的第一个玩家手触摸放置胶囊的第二个玩家主体时，它将调用一个函数。但是在脚本中它不会打电话..我不知道是什么问题..任何人都可以指导我。这是我的脚本

f_inAirStartTime = Time.time;

好的。我假设您既没有收到 OnCollisionEnter 也没有收到 OnTriggerEnter 调用。

确保具有这些方法的脚本位于具有 collider-component 的实际 GameObject 上。

OnCollisionEnter-参考：

“请注意，仅当其中一个碰撞器还附加了非运动学刚体时才会发送碰撞事件。”

总结一下：OnCollisionEnter 仅在您实际使用物理系统因力、碰撞等原因移动对象时才会调用。

如果你只想注册一个命中而不让它通过物理系统引起移动，你可以使用 OnTriggerEnter。 在这种情况下，刚体必须在移动的物体上，并且至少有一个涉及的碰撞器必须设置为 isTrigger。

还要确保在 projectSettings->Physics 中将图层设置为碰撞。

希望对你有所帮助。
