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;
}
