cocos2dx 3.3 跑酷游戏 人物的创建

人物的创建之前先建个头文件用来放一些设定Def.h(这是我后期写好了，以后想到哪些设定就在这里修改)：

#pragma once
//人物的运动状态
const int STATE_PLAYER_RUN = 0;
const int STATE_PLAYER_JUMP = 1;
const int STATE_PLAYER_DOWN = 2;
const int STATE_PLAYER_STOP = 3;
const int STATE_PLAYER_DIE = 4;
//人物速度和加速度
const double DEFLAUT_SPEEDY = 4;
const double DEFLAUT_ACCE = 0.1;
//地图左移大小（速度）
const int MOVING_GAP = 8;
//人物动作动画tag
const int TAG_RUN = 1;
const int TAG_JUMP = 2;
const int TAG_DOWN = 3;
#define MUSIC_GOLD "gold.mp3"
#define MUSIC_TOUCH "touch.wav"
#define MUSIC_BACKGROUND "background.mp3"
#define MUSIC_JUMP "jump.mp3"

注意新建项的存放位置是classes文件夹下游戏中只有一个人物，所以打算使用单例模式，模仿Director建立静态的getInstance（）；人物应该有跑动，跳跃，落下，死亡4个状态，目前是这4个，有可能会增加；人物跳跃时y速度和加速度很难定，试了很多次，现在的效果还不是很好

#pragma once
#include "cocos2d.h"
#include <string>
#include "Def.h"//设定文件放在该头文件中
using std::string;
USING_NS_CC;
class Player :public Sprite
{
public:
Player(){}
~Player(){}
static Player *getInstance();//建立静态成员变量，返回初始化好的一个静态的sharePlayer*；
bool setPlayState(int PlayState);//设置人物状态
int getPlayState();//获得人物状态，根据需要来写
void jump();//处理跳跃
void run();//
void down();//
void setSpeed(double v);//设置速度。。。没用到了后来。。。弃
private:
static Player *sharePlayer;

bool createPlayer();//创建人物
bool init();//初始化
Animation *animationRun;//人物运动动画
bool m_RunActionIng;
Animation *animationJump;//弃。。。决定只用一张图
Animation *animationDown;//弃。。。
AnimationCache *animationCache;//动画缓冲

SpriteFrameCache *frameCache;
int m_playerState;//人物状态
double speedy;//y速度
double accelerate;//y加速度
void actionCallBack(float f);

};

Player.cpp:照例初始化先

#include "Player.h"
Player *Player::sharePlayer = nullptr;//类静态成员变量的初始化
Player *Player::getInstance()
{
if (sharePlayer == NULL)
{
sharePlayer = new Player;
if (!sharePlayer->init())
{
delete sharePlayer;
sharePlayer = nullptr;
}

}
return sharePlayer;
}
bool Player::init()
{
//Sprite::init();
m_playerState = STATE_PLAYER_RUN;
speedy = DEFLAUT_SPEEDY;//极其麻烦的速度设置
accelerate = DEFLAUT_ACCE;
frameCache = SpriteFrameCache::getInstance();
frameCache->addSpriteFramesWithFile("Resources_Pack_0.plist");//添加精灵帧缓存
createPlayer();

return true;
}

人物和动画的创建：

bool Player::createPlayer()
{
Sprite::initWithSpriteFrame(frameCache->getSpriteFrameByName("run01.png"));
animationRun = Animation::create();
for (int i = 1; i < 10; i++)
{
string s = "run0" + std::to_string(i) + ".png";
animationRun->addSpriteFrameWithFileName(s);
}
animationRun->addSpriteFrameWithFileName("run10.png");
animationRun->addSpriteFrameWithFileName("run11.png");
animationRun->setDelayPerUnit(0.1f);
animationRun->setLoops(-1);
auto animateRun = Animate::create(animationRun);
animateRun->setTag(TAG_RUN);
//	runAction(animateRun);
m_RunActionIng = false;//这里要设置一个变量，判断人物是否在run，由不在到在要运行动画，否则不运行
animationCache = AnimationCache::getInstance();
animationCache->addAnimation(animationRun, "run");
//人物运动定时器
this->schedule(schedule_selector(Player::actionCallBack), 0.016);//利用状态机，每帧检测人物状态来判断该进行什么运动

return true;
}

void Player::actionCallBack(float f)
{
switch (m_playerState)
{
case STATE_PLAYER_RUN:
run(); break;
case STATE_PLAYER_JUMP:
jump(); break;
case STATE_PLAYER_DOWN:
down(); break;
default:
break;
}
}

人物运动状态函数的实现

void Player::jump(){this->stopActionByTag(TAG_RUN); //通过标记来停止动画m_RunActionIng = false; //表示下次人物run 的话要运行动画了this->setSpriteFrame(SpriteFrame::create("run03.png",Rect(0,0,64,48))); //设置人物跳起来时的画面int x = getPositionY();this->setPositionY(getPositionY()+speedy); //改变人物y值，使其向上运动speedy -= accelerate; //速度减小if (speedy<=0) //速度小于等于零则要下落{m_playerState = STATE_PLAYER_DOWN;//speedy = DEFLAUT_SPEEDY; //改到其他地方去了，}//CCLOG("IS JUMPING");}void Player::down(){stopActionByTag(TAG_RUN); //即使没有run的动画，停止也没事m_RunActionIng = false; //同上setPositionY(getPositionY() - speedy);speedy += accelerate;//下落的状态改变会有碰撞检测来实现//	CCLOG("is DOWNING");}void Player::run()//运动{//	CCLOG("IS RUN");if (m_RunActionIng == false)//动画不在播放才能播放动画{Animate *animate = Animate::create(animationCache->getAnimation("run"));animate->setTag(TAG_RUN);runAction(animate);//运行动画m_RunActionIng = true;}//int xx = this->getPositionX();//调试信息// int yy = this->getPositionY();//	CCLOG("x=%d y=%d", xx, yy);}

bool Player::setPlayState(int PlayState){this->m_playerState = PlayState;return true;}int Player::getPlayState(){return m_playerState;}void Player::setSpeed(double v){speedy = v;}
