通过对角色当前状态的属性进行判定, 以此为依据来控制角色的移动. 以及角色是否处于可站立的位置
地图移动模块(只可向右移动)
判定角色在屏幕中所处的位置, 当角色处于屏幕中央位置及向右移动时, 地图随之向右移动.
角色死亡后的出生点判断
角色死亡后将会出生在屏幕最左端的可站立的方块上
需要对角色位置进行判定的是是否通过移动方块, 若未通过, 佳能复活在移动方块左端的方块之上
角色的死亡判定(碰撞检测)
private void heroDeathCheck()

规定角色可以站立而不死亡的位置
3.代码改进及任务的分配
3.1
在学习了借鉴的代码之后, 我们对其进行了一定程度的优化, 增加了一些原来没有的功能
1.增加了难度的设置, 让玩家有了更多的选择
2.使用了缓存的技术, 解决了闪屏的问题
3.增加了角色的死亡位置判定, 使其能在移动方块左方出生
3.2小组任务分配
沈宇涛: Frame窗口, 绘制动画, 地图设定, weapon类
唐洪俊: 人物类设计, 难度调整, 解决Java运行时的闪屏问题
蔡丰骏: Bulet类, 键盘监听, 素材绘制
4.课设总结
Java代码的团队合作不同于之前的c, 需要大家的配合, 规范的命名以及写法, 让我受益匪浅. 在这次课设中我锻炼了我自己, 也知道了自己的很多不足, 在编写的过程之中我们也遇到了很多困难, 在很多我不会的地方, 其他组员也对我伸出了援手. 在共同的努力之下完成了这次的课程设计.
