HTML5 游戏 West Fighting, 西途决斗 - 原创

近年HTML5 正火热中，看到很多人开始熟悉HTML5，我也凑凑时间学点，边工作边写，上班闲闲时悄悄用HTML5写一个游戏来玩,呵呵...一边学习HTML5一边学习点游戏开发，很有意思......以下是俺从构思，设计，代码，功能实现等等都是很原始设计...花了几天时间拿来晒晒...
HTML5 GAME West Fighting[决斗西途]，设计
================================================================================================
GAME内容：
GAME内容是一对多[1:50]的决斗情况，类似USA西部片中牛仔西行一路的过关决斗奋力搏斗前行情况，可以自己想像丰富点^_^；
------------------------------------------------------------------------------------------------
相关名词定义：
---------------
1，游戏结束定义：当西部牛仔死了（生命值为0时），就当整个游戏结束了；2，个体死亡定义：生命值为零时定义为死亡，初始牛仔生命值120，其他的（称部落族人）为80--100随机赋值，族人死忙后即消失；3，移动速度：允许西部牛仔行走速度可慢[1]可快[按ctrl键加速，4]，初始牛仔行走速度1，族人1--3随机值；4，聚合性和准确性：牛仔可以任意行走，族人动态向着牛仔方向移动，方向的准确度为90%；5，决斗开始和结束定义：每个部落族人和牛仔方圆距离为小于2即开始战斗，距离大于等于2即为离开结束战斗；6，个体杀伤力定义：牛仔杀伤力为1，族人杀伤力为1~3的随机值，每跟一个部落族人战斗牛仔生命值减小2（故避免被群殴^_^）,同样部落族人的生命值也减小1；7，搏斗性定义：搏斗性仅限牛仔，即在决斗开始后到决斗结束期间，牛仔每按依次 F 键，生命值增加 2 ，但不能高于初始化的生命值；8，提示性：每次战斗开始时出现提示，各个的生命值，战斗结束即可隐藏提示；9，关于血瓶和生命值：仅限牛仔，每隔一定时间[30秒]随机位置出现一个漂流血瓶，血值20点，牛仔跑到血瓶距离小于2时，按某键[H]即逐步喝血，距离大于等2时停止喝血，当喝完或者血瓶漂出场景即消失，血瓶移动的速度为慢即1；（这个功能到以后再实现）10，状态栏：现实牛仔的生命值，和XY坐标位置，部落族人战斗人数和死忙人数，GAME暂停，继续，重新开始，结束；------------------------------------------------------------------------------------------------HOW TO PLAY, 如何玩
1，红色为牛仔，按方向键或ASDW键移动，如果按住 CTRL 键则加速移动，2，每按族人和牛仔接近足够距离就开始战斗，3，族人和牛仔生命值为0即死亡，4，按 X 查看所有族人的生命值，按 C 查看牛仔的生命值，战斗开始后不断的按 Z 键可以增加博斗能力，即增加牛仔生命值游戏开始可能得刷新几次，等图片下载完成后才好操作；不多说了，先看图游戏开始界面
游戏开始后截面
游戏使用的人物动作分解图，那个有更好的可以完善，俺只是简单的做了一下，很陋也，不过看那些族人和牛仔走东蛮生动的，呵呵，有点意思以下是核心代码： <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

</html>太长。实在写不完了，省掉些...我把这个压缩到上穿到csdn资源
楼主上面给出的超链接地址不对...
貌似应该是：
http://blog.csdn.net/shenzhennba/article/details/7079986
HTML5还没接触过呀。。学习下。。
找时间学学，觉得html5是趋势啊
楼主，可以用jquery1.7来制作不？？
顶一个，最近也在用html5写游戏，写的有点乱，先收藏，有时间再来慢慢研究
感觉强大的不是HTML5  而是JS
难道是浏览器问题?复制粘贴之后运行error
虽然看不懂，但是感觉HTML5好牛。
HTML5还没开始学习，边学边做，楼主强大！
学习呀，谁有HTML5教学视频，找了几本书，都是英文的，好难
HTNL5 + CCS3  听说这是将来的趋势啊，变化也太快了
请问是HTML5+CSS吧？怎么是ccS 呢？
HTML5还没接触过呀。。学习下。。
谢谢，隔一段时间没上了，才发现连发了3次就不能发了，呵呵，
奥得曼狂殴小怪兽，这些图我没有，你有吗？如果有给我一份，再来改改
图形多的更形象点，如果一个动作的分解图太多，制作比较麻烦点，图方便我就简4步一个动作完成了，呵呵谢谢，提示，上周6我下午有事，匆忙发完就出去了，没检查到，今天才回来上班，可能太多了，到时增加些说明...图形很原始，很简陋，...连贯起来，有点意思，什么技能呢？能说说吗？我也不清楚，如果增加什么技能，可能又有相应的图要增加...我就简单的处理了说得对，到后面多了，我也感觉有点乱，再多有点把不住的感觉，
这个应该可以，我这里没有好的图，如果哪个能给或制作一份更丰富的各个动作分解图，就好了制作规格：
在一个大图片里，分多个行列的格子，每个格子50x50像素，每一个动作，在一个格子里画，从左到右，把各个动作分解完成，就象我上面的分解图一样；图我给了几个，但这里好像只显示一个插图，估计是我把图片地址弄错了，博客里面还有这里的代码不完整，三次贴不完，有点多了，我博客里有完整的，复制，在记事本里保存成.html或.htm后缀的就可以了，浏览器要支持HTML5的才可以哪个有比较丰富的人物动作分解图给一份，制作也可以，我送高分给，人物美工我不太会，设计很简陋我也是从网上学的，看到点就学点，没系统学过，
应该可以的，但我那里不用jquery
游戏的框架说明如下：大致是这样的：游戏页面加载初始化界面相关，然后是游戏封面，游戏开始后，主要就是画布canvas的操作，不断地每隔一段时间刷新画布,刷新的内容有比较多，按游戏前面的相关定义去实现，new 指定个数的族人，和牛仔加入，位置更新，距离判断，方向修改，决斗画面制作，决斗数据更新等等...有空在增加血瓶功能
总之象电影播放一样一桢一桢的播放那样...各个对象或类，方法分别说明如下：
