9.13总结

道具的实现，运用文本api，在场景中显示出金币的数量
for (int i = 0; i < ItemVec.size(); i++){
if (aa->getBoundingBox().intersectsRect(ItemVec.at(i)->getBoundingBox())){
coin1 += 1;
ItemVec.at(i)->removeFromParent();
ItemVec.eraseObject(ItemVec.at(i));
char string[20] = { 0 };
sprintf(string, "coin:%d", coin1);
auto label2 = (Label*)getChildByTag(12);
label2->setString(string);
}
}
飞机和生命值道具的碰撞，然后删除
for (int j = 0; j < HpVec.size(); j++){
if (abc->getBoundingBox().intersectsRect(HpVec.at(j)->getBoundingBox())){
HpVec.at(j)->removeFromParent();
HpVec.eraseObject(HpVec.at(j));
heroHp += 100;
}
}
飞机hp的边界要注意，否则会出现打不死boss ，而且我机不死亡的现象
 if (heroHp > 0){
 for (int j = 0; j < BultVec.size(); j++){
 if (abc->getBoundingBox().intersectsRect(BultVec.at(j)->getBoundingBox())){
 heroHp-=10;
 BultVec.at(j)->removeFromParent();
 BultVec.eraseObject(BultVec.at(j));
 char string[10] = {0};
 sprintf(string, "HP:%d", heroHp);
 auto label1 = (Label*)getChildByTag(10);
 label1->setString(string);
 CCLOG("%d", heroHp);
 }
 }
}


 if (heroHp<=0){
 //this->unscheduleAllSelectors();
 auto scene = GameScene2::createScene();
 Director::getInstance()->replaceScene(TransitionFade::create(2, scene, Color3B::WHITE));
 }




boss的文本，扣血，也同样要注意边界
for (int i = 0; i < ddd.size(); i++)
{


for (j = 0; j < aaa.size(); j++)
{
if (ddd.at(i)->getBoundingBox().intersectsRect(aaa.at(j)->getBoundingBox()))
{
bosshp -=10;
//d1->remove4(ddd.at(i));
a1->remove(aaa.at(j));
char string[20] = { 0 };
sprintf(string, "bosshp :%d", bosshp);
auto label3 = (Label*)getChildByTag(8);
label3->setString(string);
if (bosshp <= 0){
d1->remove4(ddd.at(i));
bosshp = 10000;
}
