（Visual C++）游戏开发笔记十六 讲解一个完整的回合制游戏demo
上一篇：http://www.2cto.com/kf/201204/126625.html
首先，我们来了解这种行为型AI的设计方法。
游戏程序中计算机角色的思考与行为，实际上是对各种不同事件进行分析思考，然后根据不同的情况作出相应的反应。但如何对发生的条件进行判断，并作出相应的反应呢？
对，我们可以利用“if-else”条件句以及“switch-case”语句这类的判断式来完成。
通常情况下，设计此类AI，会涉及到连串的条件判断句，简单数学运算，及一些数据结构的知识。
下面我们就来具体讲解这个demo涉及到的一些知识点：
一、AI怪物攻击与思考方式设计
例如今天我们要展示的这个回合制游戏demo里的AI，就有如下几种行为：
（1）利爪攻击
（2）闪电链攻击
（3）致命一击
（4）使用梅肯斯姆回复生命值
（5）逃跑
那么我们可以根据以上设计的怪物行为，设计以下一段算法，用来模拟怪物对战时的思考与行为的方式
[cpp]
if(monster.nHp > 20) //生命值大于20
{
if(rand()%5!= 1)
//进行利爪攻击概率4/5
else
//进行闪电链攻击概率1/5
}
else //生命值小于20
{
switch(rand()%5)
{
case 0: //利爪攻击
break;
case 1: //释放闪电链
break;
case 2: //致命一击
break;
case 3: //使用梅肯斯姆回复 ;
break;
case 4: //逃跑
if(1== rand()%3 ) //逃跑成功几率1/3
//逃跑成功
else
//逃跑失败
break;
}
}
if(monster.nHp > 20) //生命值大于20
{
if(rand()%5!= 1)
//进行利爪攻击概率4/5
else
//进行闪电链攻击概率1/5
}
else //生命值小于20
{
switch(rand()%5)
{
case 0: //利爪攻击
break;
case 1: //释放闪电链
break;
case 2: //致命一击
break;
case 3: //使用梅肯斯姆回复 ;
break;
case 4: //逃跑
if(1== rand()%3 ) //逃跑成功几率1/3
//逃跑成功
else
//逃跑失败
break;
}
}
这段代码中，利用if-else判断式判断怪物生命值，然后怪物有4/5的几率释放普通的利爪攻击，有1/5的几率释放闪电链魔法攻击，当怪物重伤生命值小于20点时，也有一定的几率逃跑。
以上的利用“if-else”、“switch”语句，使计算机角色进行事件情况判断，然后写出相应的动作实现代码，这就是行为型游戏AI
设计的核心精神。
二，玩家角色攻击方式设计
然后我们再来设计一下玩家的攻击技能。
今天放出的这个demo里我给人物设定了两个技能，一个主动的普通攻击技能“无敌斩”，伤害计算公式为damage = rand()%10 + player.lv*player.w（player.lv为角色等级，player.w为攻击系数）。
而被动技能为可以有一定几率打出4倍暴击伤害的“恩赐解脱”，这个技能是Dota里面幻影刺客
的大招（呵呵，浅墨玩dota时可是超级幻刺控~~）。
其实暴击的实现方式很简单，就是用if条件句进行概率的判断（浅墨在这里利用4==rand( )%5来设定暴击概率为20%），如果判断成功就将“倍率x普通攻击”作为damage的值。
（哈哈，浅墨专门找到了Dota里面这两个技能的图标
以及
用到了这个demo里面，具体效果图在下面）
下面贴出实现人物技能的代码：
[cpp]
if (4==rand()%5) // 20%几率触发幻影刺客的大招，恩赐解脱，4倍暴击伤害
{
damage = 4*(rand()%10 + player.lv*player.w);
monster.nHp -= (int)damage;
sprintf(str,"恩赐解脱触发，这下牛逼了，4倍暴击...对怪物照成了%d点伤害",damage);
}
else
{
damage = rand()%10 + player.lv*player.w;
monster.nHp -= (int)damage;
sprintf(str,"玩家使用了无敌斩，伤害一般般...对怪物照成了%d点伤害",damage);
}
if (4==rand()%5) // 20%几率触发幻影刺客的大招，恩赐解脱，4倍暴击伤害
{
damage = 4*(rand()%10 + player.lv*player.w);
monster.nHp -= (int)damage;
sprintf(str,"恩赐解脱触发，这下牛逼了，4倍暴击...对怪物照成了%d点伤害",damage);
}
else
{
damage = rand()%10 + player.lv*player.w;
monster.nHp -= (int)damage;
sprintf(str,"玩家使用了无敌斩，伤害一般般...对怪物照成了%d点伤害",damage);
}

每一回合开始的时候，我们点击画面上“无敌斩”的技能图标，就可以进行攻击，对怪物造成伤害，人品好的话，还可以触发强力被动技能“恩赐解脱”，对怪物造成4倍暴击伤害，这里我们设定的暴击概率为20%
浅墨在截图的时候，人品挺好的，恩赐解脱的暴击概率为20%，但是浅墨的4次攻击里，有3次都打出了“恩赐解脱”的暴击效果，直接果断地把这只小绵羊带走了，呵呵。
下面就是游戏运行的截图：
游戏开始
第一刀就出暴击了，48点伤害
运气不错，又一刀暴击，68点伤害
最后一刀又出了暴击，小绵羊被“秒杀”，游戏结束
我们还可以调节怪物等级，怪物攻击加权值，怪物血量上限以及玩家角色等级，玩家角色攻击加权值，玩家角色血量上限来让游戏更具挑战性。
当然，我们也可以增加更多的代码，来使怪物的思考与行动方式更具真实性和多样性，来使玩家的技能更加丰富。
