平行过渡的运动问题´；JavaFX8中的s事件处理程序
我正在用javafx做一个大学项目：一个类似于太空入侵者的游戏。我试图用一个平行过渡制作每个ovni的动画，创建一个时间线动画，并将其添加到每个ovni的平行过渡中，为它们中的每一个管理EventHandler，以便将ovni移动到X位置，并在窗口左边界时移动到Y位置。问题是，当我播放动画时，只有第一行在X位置正确移动，但其他行没有。换句话说，当其他行在x位置移动一定距离时，它们不会在rigth边界上完成运动，而是在Y位置移动。结果如下： 这是构建OVNI的方法：平行过渡的运动问题´；JavaFX8中的s事件处理程序,java,javafx,javafx-8,Java,Javafx,Javafx 8,我正在用javafx做一个大学项目：一个类似于太空入侵者的游戏。我试图用一个平行过渡制作每个ovni的动画，创建一个时间线动画，并将其添加到每个ovni的平行过渡中，为它们中的每一个管理EventHandler，以便将ovni移动到X位置，并在窗口左边界时移动到Y位置。问题是，当我播放动画时，只有第一行在X位置正确移动，但其他行没有。换句话说，当其他行在x位置移动一定距离时，它们不会在rigth边界上完成运动，而是在Y位置移动。结果如下： 这是构建OVNI的方法： public Shape bu

对于（int i＝0；i您逐行更新位置并重新计算最右边的位置。按顺序将<代码>时间线< /代码> s添加到<代码>并行转换< /代码>中，在右下角更新之前，右上角OVI被更新，这意味着那些OUVIS将考虑要到达的最右边的位置。导致问题的最顶行ouvis前的“帧”
附加说明：
在这种情况下，使用并行转换
是不必要的/低效的，因为单个时间线
可以处理所有的关键帧
s。此外，甚至多个关键帧
s都是不必要的，因为ouvis都是在同一时间更新的，甚至一些值也应该重用
