Java 编写大鱼吃小鱼游戏窗体程序完整源码

末蓝、 2024-03-27 16:13 68阅读 0赞

今天为大家分享大鱼吃小鱼游戏开发与制作。整个系统界面漂亮，有完整得源码，希望大家可以喜欢。喜欢的帮忙点赞和关注。一起编程、一起进步

## 开发环境 ##

开发语言为Java，开发环境Eclipse或者IDEA都可以。运行主程序，或者执行打开JAR文件即可以运行本程序。

## 系统框架 ##

利用JDK自带的SWING框架开发，不需要安装第三方JAR包。纯窗体模式，直接运行Main文件即可以。同时带有详细得设计文档

## 主要功能 ##

对FishFrame.java点右键，run as Application，启动大鱼吃小鱼得游戏。

点击enter键，开始玩游戏

通过键盘的上下左右四个方向的键盘控制大鱼的方向，当大鱼和随机游过来的小于发生碰撞的时候，表示吃掉相应的小于，分数加10分。大鱼的战斗力相应增加。

一局游戏最多5分钟，超过5分钟，游戏结束。

屏幕的最顶端显示游戏当前得分和，大鱼的战斗力。随着游戏的不断推进，数字不断进行更新。

## 实现效果 ##

## 项目总结 ##

开发一套系统，最重要的是细心，并不是一定要做到面面俱到，在准备工作中要正确分析社会需求了解现实应用，画出流程图，把大体框架做好，然后再逐一细化。我们不可能做到面面俱到，但一定要做到步步扎实，作为一个程序编程人员，要保持清醒的头脑，以现实为依据，让自己的每一行代码都能实现自己的意义。 通过这次系统开发，我收获的不仅仅是课程上的知识得到实际应用，还有编程的基本习惯和开发系统时应注意的流程。
