用于碰撞检测的AnimationTimer（）

Question

我有两个游戏对象，即矩形，玩家和敌人。我希望玩家在Y轴上跳跃，敌人沿X轴滑动。当玩家的X，Y位置与敌人匹配时，它应该杀死玩家。到目前为止，我无法通过AnimationTimer（）来检查每个帧的常量X位置和Y位置。它仅检查应用程序何时首次启动并保留这些值。

如何检查每个帧的两个矩形的X位置和Y位置？

AnimationTimer animator = new AnimationTimer() {
        public void handle(long arg0) {
            //update

            double playX = player.getX(), enemX = enemy.getX();
            double playY = player.getY(), enemY = enemy.getY();
            System.out.println("Player's X: "+ playX + "\n" + "Enemy's X: " + enemX);
            System.out.println("Player's Y: "+ playY);

            if (playX == enemX && playY == enemY){
                System.out.println("Player has Collided with Enemy");
            }

        }//handle
    };
    animator.start();//animation

尝试类似：

Shape intersect = Shape.intersect(player, enemy);

if(intersect.getBoundsInLocal().getWidth() != -1)
{
    System.out.println("Player has Collided with Enemy");
}
