刚学习cocos，按照mercuryrozen瓦片地图教程自己跟到做了一个，但是碰撞判断有问题啊。
1、地图下方，感觉坐标都有问题了，下方的碰撞判断有问题；
2、左边的障碍物这一列居然在地图中不显示了；
3、上边和右边的地图碰撞是对的。
附上主要代码：
bool HelloWorld::init()
{
std::string file = “first.tmx”;
auto str = String::createWithContentsOfFile(FileUtils::getInstance()->fullPathForFilename(file.c_str()).c_str());
_tileMap = TMXTiledMap::createWithXML(str->getCString(), “”);
_background = _tileMap->getLayer(“background”);
_blockage = _tileMap->getLayer(“blockage01”);
//_blockage->setVisible(false);
addChild(_tileMap, -1);
TMXObjectGroup* objects = _tileMap->getObjectGroup("Object-Player");
CCASSERT(NULL != objects, "'Object-Player' object group not found");
auto playerShowUpPoint = objects->getObject("PlayerShowUpPoint");
CCASSERT(!playerShowUpPoint.empty(), "'PlayerShowUpPoint not found");
int x = playerShowUpPoint"x"].asInt();
int y = playerShowUpPoint"y"].asInt();
_player = Sprite::create("029.png");
_player->setPosition(x + _tileMap->getTileSize().width / 2 / Director::getInstance()->getContentScaleFactor(),
y + _tileMap->getTileSize().height / 2 / Director::getInstance()->getContentScaleFactor());//将逻辑坐标转换为GLVIEW坐标
_player->setScale(1.0 / Director::getInstance()->getContentScaleFactor());
//_player->setPosition(x + _tileMap->getTileSize().width / 2, y + _tileMap->getTileSize().height / 2);
//_player->setScale(0.5);
addChild(_player);
setViewPointCenter(_player->getPosition());
