Question

最奇怪的事情不断发生，我无法弄清楚原因。我想在我的代码中实现它们，而不仅仅是设置20个不同的预制件。我正在制作一个太空入侵者C＃游戏，我使用下面的代码得到第一排入侵者。字面上根本没有任何问题，他们也移动我想要的方式。但是一旦我设置了第二行，我用于第一行的transform.position语法突然不适用，它只是将我的transform.position.x设置为0.我确实有另一个类可能是原因，但到目前为止，我还没有找到解决这个问题的方法。提前感谢您的帮助。

Answer 1

在moveX1（）中你正在使用newX，你有时可能在firstMove之前调用moveX1吗？如果是这样，那么newX将是未定义的和0。

Answer 2

想出来。我在moveX1（）函数的开头添加了newX = newPosX.x;行：感谢所有尝试过的人！

Unity3D transform.position.x保持设置为0
