编程一个最简单游戏代码(免费java游戏代码大全)
本文实例为大家分享了Java实现方块赛跑小游戏的具体代码,供大家参考,具体内容如下
在一个图形界面上构造两个位于同一起跑线方块,起跑线位于界面靠左位置, A 方块先开始运动,向右移动 50 像素后停止,B 方块开始运动,向右移动 100 像素后停 止,A 方块继续向右运动 100 像素后停止,B 方块开始运动,如此循环接替执行,直至 某一个方块到达终点,界面显示该方块胜利信息。
1) 自定义一个threadA,ThreadB, ThreadFrame类(均继承自Thread)。
2) 定义全局变量,方块的位置,总长度,冠军,睡眠时间等,布尔值方块等待变量、游戏继续变量、绘图变量
3) ThreadA(ThreadB):等待waitA(waitB)变量释放,即:等待另一个方块更新完位置;然后随机产生要移动的长度,检查运动后位置与总长度的关系,以此判断游戏是否结束。更新位置信息,更改绘图变量,通知绘图线程重绘。自锁本身,释放另一个方块线程。
4) ThreadFrame:创建类对象,重写run函数,等待绘图变量的命令。接到绘图命令,重绘,判断游戏释放结束,重置绘图命令。
5) 构造函数,paint函数绘制,并进行游戏是否结束的判断,若结束,则打印冠军是谁,退出
6) 主函数,定义threadA,ThreadB, ThreadFrame类的对象,运行。用jion函数等待子线程的结束。
