重叠的精灵检测算法问题

我正在尝试查看2个子弹精灵是否基本重叠。他们是15x15。顺便说一句，bsize是15。 30代表两个15，基本上是捷径。如果其中一个可行，我将回过头来修复15s和30s硬编码。如果它们重叠，则很受欢迎。

我不知道我的代码在哪里，因为我尝试了3种不同的技术，这些技术是由各种堆栈溢出论坛针对同一件事提出的。因此，请不要将其标记为重复项，我已经很清楚了所有这些标记，并且已经尝试过这些标记，并且在我的代码中，您将看到3种不同的尝试，这些尝试是通过尝试建议的堆栈溢出获得的。我只需要其中之一即可工作。我基本上只是绕开了矩形，因为它是多余的，但是除了我要告诉矩形的点在哪里，这基本上就像它。

ArrayList<BulletClass> bCollect1=new ArrayList<BulletClass>();
        ArrayList<BulletClass> bCollect2=new ArrayList<BulletClass>();
        for (int i=0;i<bCollection.size();++i) {
            if (bCollection.get(i).dir==0) {
                bCollect1.add(bCollection.get(i));
            }
            else if (bCollection.get(i).dir!=0) {
                bCollect2.add(bCollection.get(i));
            }
        }
        BulletClass a;
        BulletClass b;
        for (int i=0;i<bCollect1.size();++i) {
            for (int j=0;j<bCollect2.size();++j) {
//              Rectangle ob1=new Rectangle(bCollect1.get(i).bulletLocation(0),bCollect1.get(i).bulletLocation(1),bCollect1.get(i).bsize,bCollect1.get(i).bsize);
//              Rectangle ob2=new Rectangle(bCollect2.get(j).bulletLocation(0),bCollect2.get(j).bulletLocation(1),bCollect2.get(j).bsize,bCollect2.get(j).bsize);
//              if (ob1.intersects(ob2)) {
//                  System.out.println("Hit");
//                  a=bCollect1.get(i);
//                  b=bCollect2.get(j);
//              }
//              if ((bCollect1.get(i).bulletLocation(0)<(bCollect2.get(j).bulletLocation(0)+15))&&((bCollect1.get(i).bulletLocation(1)+15)<(bCollect2.get(j).bulletLocation(1)+30))&&((bCollect2.get(j).bulletLocation(0))<(bCollect1.get(i).bulletLocation(0)+15))&&((bCollect2.get(j).bulletLocation(1)+15)<(bCollect1.get(i).bulletLocation(1)+30))) {
//                  System.out.println("Hit");
//              }
//              int x1=bCollect1.get(i).bulletLocation(0);
//              int x2=bCollect1.get(i).bulletLocation(0)+bCollect1.get(i).bsize;
//              int x3=bCollect2.get(j).bulletLocation(0);
//              int x4=bCollect2.get(j).bulletLocation(0)+bCollect2.get(j).bsize;
//              int y1=bCollect1.get(i).bulletLocation(1)+bCollect1.get(i).bsize;
//              int y2=bCollect1.get(i).bulletLocation(1);
//              int y3=bCollect2.get(j).bulletLocation(1)+bCollect2.get(j).bsize;
//              int y4=bCollect2.get(j).bulletLocation(1);
//              if (!((x3>x2)||(y3>y2)||(x1>x4)||(y1>y4))) {
//                  System.out.println("Hit");
//              }
            }
        }

bulletLocation（0）表示x位置，其中1表示y位置。在向大家展示我正在尝试的失败尝试之后，我基本上一直在逐一评论每个人，实际上我做了4项不同的事情，但手动做了3件事，以使用站点上的各种论坛。无论如何，我能看见的子弹彼此重叠，但我没有打印出“ hit”一词。如果您要我张贴3-4个尝试使用的Fourms，则可以这样做。但是请不要标记为重复，或者至少不要标记为重复，直到我得到一个有效的答案为止。如果有的话，谁能告诉我为什么相交方法不起作用？预先感谢。
