cocos2dx 3.2 为什么分数变不了，求高手指点

Cocos2d-x
#1

score=0;

auto label=LabelTTF::create(“Score : 0”,“Arial”,24);

label->setPosition(Vec2(800,600));

label->setTag(110);

this->score+=100;

Label *lab=(Label *)this->getChildByTag(110);

char strscore;

sprintf(strscore,“Score : %d”,score);

lab->Label::setString(strscore);

#2

总觉得你没有addchild…
