[求助]TMXObjectGroup 使用崩潰

Cocos2d-x
#1

TMXObjectGroup* objGroup = map->getObjectGroup(“object”);
ValueMap playerPointMap = objGroup->objectNamed(“PlayerPoint”);
float playerX = playerPointMap.at(“X”).asFloat();
float playerY = playerPointMap.at(“Y”).asFloat();
mPlayer->setPosition(Point(playerX, playerY));

上面代码不知道那错了,一运行就崩溃,找了2天没头绪,求助各位大神!!谢谢!

窃乱猜下。。没用过瓦片底图
1.没有对应的字段
2.字段的大小写不对(不知道敏不敏感)
