以下爲幾個使player運動的函數的實現
/*
void HelloWorld::pmhcollision() //
{
CCPoint playerpoint = player->getPosition();
//獲得玩家的方位
CCSize playersize = player->getContentSize();
//獲得玩家圖片的尺寸
CCTMXTiledMap* map = (CCTMXTiledMap*) getChildByTag(kTagTileMap); //獲得地圖屬性
int indexx,indexy;
char mch[256];
CCTMXLayer* layer = map->layerNamed("logic");
//獲得tmx地圖的logic層的layer
for(int playery = playerpoint.y - playersize.height;playery <= playerpoint.y;playery ++)
{//轉換爲tile座標
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); //獲取此方位的tilegid（tiled定義的圖片編號）
if(tilegid > 0)
{
CCMutableDictionary<string,CCString *> *tiledic = map->propertiesForGID(tilegid);
//獲取tilegid上的properties的屬性

Cocos2dx完美支持tiled製作的tmx格式圖片，此格式爲tilemap圖片，方便了場景的製作，降低了工作量。
Player的準備工作已完成，接下來就開始讓player人物動起來
