2. Java 编写 贪吃蛇游戏的 大体思路是什么

在画布上，我们首先需要画出蛇的头部，这代表了贪吃蛇游戏的起点。虽然蛇会随着游戏的进行而变长，但它的基本构造仍然是由一系列坐标点组成的，我通常使用LinkedList来存储这些坐标点，因为它的插入和删除操作更为高效。这里的每个坐标点实际上代表了蛇的一个“块”。

为了让蛇移动起来，我们需要一个线程来调用move()方法，这个方法将负责蛇的每一次移动。同时，我们还需要确保蛇的移动具有方向性。为了实现这一点，我们可以编写一个方法，通过接收一个方向参数来控制蛇的移动方向，同时还需要一个机制来禁止蛇在移动时改变与当前方向相反的方向。比如，如果当前蛇的方向是向上移动，那么它就不能向下移动。

当蛇与边界接触时，游戏应当结束。因此，我们需要在蛇移动的过程中检查它是否越过了边界，如果越界则游戏结束。接下来是食物的出现，食物的位置需要随机生成，但必须确保它不会出现在边界之外。当蛇吃到食物时，需要有一个方法来处理这一事件，比如增加蛇的长度，并在适当的位置生成新的食物。

此外，如果蛇与自己的身体发生碰撞，游戏同样需要结束。这可以通过遍历蛇的各个部分来检查是否有重叠来实现。如果检测到重叠，则游戏结束。这样的逻辑构成了贪吃蛇游戏的基本框架，后续则可以添加更多细节，如得分系统、不同难度级别的设定等。

通过上述步骤，我们可以大致构建出一个简单的贪吃蛇游戏。当然，这只是一个起点，实际开发中还需要考虑许多细节问题，比如用户界面的美化、游戏的优化等。但以上步骤提供了一个清晰的开发思路，对于初学者来说是一个很好的起点。

5. Java 编写贪吃蛇游戏的大体思路是什么

楼主没有看到蛇移动的本质，蛇虽然是分成很多块，但他们还是一个整体，每一块的移动都和上一块有关，所以不需要对每一块都进行判断。x0dx0a原理:x0dx0a把蛇身体的每一块看成一个对象（对象存储该块的坐标和相关信息），作为节点存储在线性链表中，再设置一个变量标志蛇的方向（通过按键可以改变）。一般人都是让每一个节点等于他指向的下一个节点，并让头节点改变位置来实差局现转弯和移动，这个算法复杂度太高（O(n))，实际上只要做两步操作，插入一个头节点，删除一个尾节点就可以了，新插入的头节点位置根据蛇当前的方向决定 用一个数组将蛇头的行径记录下来，然后第二段的下一个方格设置为蛇头走过的方格，这样子蛇走过的路径都是前一段走过的，最后将跟着蛇头走了，比如x0dx0a蛇身的路径x0dx0a for(int i=snakeLength-1;i>0;i--){x0dx0arows[i]=rows[i-1];//依次将蛇前面一段走过行的路段赋值给蛇的下一段x0dx0acols[i]=cols[i-1];//依次将蛇前面一段走过列的路段赋值给蛇的下一段x0dx0a}x0dx0afor(int i=1;i
