[最新] Java来做马里奥[0]—让精灵再次舞动

iteye17686 2008-2-26 0

记得在红白机(FC)年代,还刚刚上小学的我对马里奥、冒险岛、洛克人、魂斗罗等游戏几乎可说是痴迷,每天放学回家就是想去游戏,就是要通关,就是想和关底论个胜负高低。

许多年过去了,沧海桑田,FC曾经的荣耀早已不再,只留下我们对曾经少年时的点点记忆。即使当时在FC上看上去多么复杂,多么高不可攀的游戏,在当今,即使最普通的程序员都可以轻易实现。

本着向经典学习、向经典致敬的心情,我也准备用Java在PC机再现当年马里奥的风采。

下面我在代码中所演示的,是一个简单的ACT游戏动作及地图构成原型。

运行效果如下图:


现在开始,我会在blog中逐步构建马里奥中的一关,有关心java pc游戏开发者敬请留意。
