以下为几个使player运动的函数的实现
/*
void HelloWorld::pmhcollision() //
{
CCPoint playerpoint = player->getPosition();
//获得玩家的方位
CCSize playersize = player->getContentSize();
//获得玩家图片的尺寸
CCTMXTiledMap* map = (CCTMXTiledMap*) getChildByTag(kTagTileMap); //获得地图属性
int indexx,indexy;
char mch[256];
CCTMXLayer* layer = map->layerNamed("logic");
//获得tmx地图的logic层的layer
for(int playery = playerpoint.y - playersize.height;playery <= playerpoint.y;playery ++)
{//转换为tile座标
indexx = (playerpoint.x - playersize.width / 2) / map->getTileSize().width;//
indexy = (playerpoint.y) / map->getTileSize().height;
CCPoint playerindex = ccp(indexx,indexy);
int tilegid = layer->tileGIDAt(playerindex); //获取此方位的tilegid（tiled定义的图片编号）
if(tilegid > 0)
{
CCMutableDictionary<string,CCString *> *tiledic = map->propertiesForGID(tilegid);
//获取tilegid上的properties的属性
CCString *mvalue = tiledic->objectForKey("collion");
//将string转为int型
int mv = mvalue->toInt(); //
if(mv == 2)
{
xVel = 0;
playerpoint.x = (indexx + 1) * map->getTileSize().width + playersize.width / 2;
player->setPosition(playerpoint);//刷新player座标
}
return;
}

Cocos2dx完美支持tiled制作的tmx格式图片，此格式为tilemap图片，方便了场景的制作，降低了工作量。
Player的准备工作已完成，接下来就开始让player人物动起来
