Cocos2dx－角色创建与动画实现

本文转载于：http://www.cnblogs.com/zisou/p/cocos2d-x_arpg1.html

继续上一篇文章继续聊吧，这章内容会比较多，也会附上代码，很多朋友加了群，大家在群里面探讨了很多东西，这让大家都觉得受益匪浅，这便是极好的，废话不多了，精灵是游戏的重要组成部分，那ARPG里面的精灵必然是要做得很细的，因为精灵要能动，能跑，能打，甚至要能做各种交互动作等等。

      大家可以看一下下面的题，是精灵制作的流程思路：

　　

 

　　上图的人物素材来自于网络流传的梦幻西游，地图还有其他素材是以前公司同事制作的，如果游戏正式上线，会换一套完整的自制的素材。图中大家可以看到一个人物有很多部件组合而成，高端一点的游戏甚至部件多达几十上百种，甚至做出骨骼动画。不过以我现在的做法是按照帧动画方式实现各个人物的动作，人物的body部分细节处理会很多，还有大家看到图中的字体（字体渲染描边，我做的是最简单的了，两个LABEL合成在一起，效果能达到就行），由于人物要有方向，而且我们一次性就做8方向的人物动画，那就需要8个方向的连帧图片：

　　首先，要组装起来我们首先要建一个实体角色类，这个类里面不放别的，就统一放角色的部件属性：

　　

MainRoledata.h类

#ifndef _MAIN_ROLE_DATA_
#define _MAIN_ROLE_DATA_

#include "cocos2d.h"
#include "../Commen_ActionToDo.h"
#include "../Commen_Direction.h"
USING_NS_CC;

class MainRoledata
{
public :

    //人物的TAG
    int tags;
    //人物姓名
    CCString* spiritname;
    //人物初始坐标
    CCPoint nowpoint;
    //人物默认像素图
    CCString* spiritUrl;
    //人物站立像素图路径
    CCString* spiritUrl_zhan;
    //人物跑动像素图路径
    CCString* spiritUrl_pao;
    //人物攻击像素图路径
    CCString* spiritUrl_attack;
    //人物施法像素图路径/增加人物BUF
    CCString* spiritUrl_magic;
    //人物站立最大帧
    int maxcut_zhan;
    //人物跑动最大帧
    int maxcut_pao;
    //人物战斗最大帧
    int maxcut_attack;
    //人物施法最大帧
    int maxcut_magic;
    //人物当前动作
    Commen_ActionToDo acttodo;
    //人物当前朝向
    Commen_Direction dir;
    //动画时间
    float actiontime;
    
};

#endif

枚举几个方向，和动作的类：

enum Commen_Direction
{
    up=0,
    down=1,
    lefts=2,
    rigth=3,
    rigth_up=4,
    rigth_down=5,
    left_down=6,
    left_up=7
};

enum Commen_ActionToDo
{
    run=1,
    stand=2,
    attack=3,
    death=4,
    funny=5,
    magicup=6
};

OK，然后配置精灵数据，建了一个GetNPCData.cpp，GetNPCData.h，主要就是拿来初始化数据，大致的思路是要将上面的Model填充数据，相信大家

能够用很多种方式去实现，填充数据（读取XML配置文件，直接写在代码中配置）；

接下来我们正式组装完整的八面玲珑的精灵，建立SpiritsPlayer.cpp，SpiritsPlayer.h；

总体思路就是，我们通过了帧连接的拼接来构成动画，通过我们之前写好的model数据来定义我们任务的朝向等问题

比如00000代表右，01000就代表右上，这个也得根据自己素材的模型来写不同的处理逻辑，万变不离其中；

如果我们的图片是在一张大图的集合中，我们可以同过CCRect来处理获取帧图片方式！

CCAnimation* getNowAnt(MainRoledata roledata);
CCAnimate* updateNowAnt(MainRoledata roledata);

通过这两个方法集合，我们就能获取到八面玲珑的朝向，甚至我们连，后续的动画机制也加入了，比如，跑动，打斗，做各种动作等！

Commen_Direction SpiritsPlayer::getNowPointDir(CCPoint newpoint); //获取朝向

void SpiritsPlayer::moveTomap_dir(CCPoint newpoint) //改变朝向方法

以上两个方法，我们是专门处理，之后精灵移动，移动完之后还得恢复到站立状态，移动过程中改变人物朝向问题！所以要考虑的很清楚

很清晰，思路清楚了，才能方便以后的拓展。

OK了，有了以上的精灵类，将其实例化到一个简单的图片地图上，他就会动了；

添加的时候我们直接addchild方法！！

SpiritsPlayer* role_main = new SpiritsPlayer(basedatas->role_player,1,false);

nowmap->addChild(role_main->npc, 999);

nowmap 暂且可以用一张图片CCSprite代替！！！

下一篇博客我会非常详细的将地图制作方法写出来给大家一起分享，由于其实我之前都是C#,JAVA做的很多，很多地方和细节还需要重构

还需要大家多指点一下，这也是我学习的好机会；
