我的 didBeginContact() 函数不起作用 SWIFT 精灵工具包
MY didBeginContact() FUNCTION DOES NOT WORK SWIFT SPRITE KIT
嗨，我已经尝试解决这个问题很长时间了，我的问题是我的 didBeginContact() 不起作用 "rocket" 与 "missiles" 发生碰撞，它们被推下但是它没有 运行 功能，我该怎么做才能修复它？
提前致谢。

}
}
我相信你在 didMoveToView 中遗漏了：
//not sure if it is needed but almost everyone sets the gravity to 0,0 unless needed
self.physicsWorld.gravity = CGVector(dx: 0, dy: 0)
另外 didBeginContact 应该在 didMoveToView 之外，而你已经把它放在里面了。
希望对您有所帮助。

我相信你在 didMoveToView 中遗漏了：
//not sure if it is needed but almost everyone sets the gravity to 0,0 unless needed
self.physicsWorld.gravity = CGVector(dx: 0, dy: 0)
另外 didBeginContact 应该在 didMoveToView 之外，而你已经把它放在里面了。
希望对您有所帮助。
