C++ 容器之 list的使用

1、List 装入引用或指针的方式

　　push_back()

　　push_front()

　　pop_back()

　　pop_front()

#include <iostream>
#include <list>
using namespace std;

class A{
public:
    virtual void print(){cout<<"A::print()"<<endl;}
};
class B: public A{
public:
    void print(){cout<<"B::print()"<<endl;}
};
int main(int argc, char* argv[]){
    A *pa = new A;
    B *pb = new B;
    list<A*> temp;
    list<A*>::iterator iter;
    temp.push_back(pa);
    temp.push_back(pb);
    for(iter=temp.begin(); iter!=temp.end(); ++iter){
        (*iter)->print();
        delete(*iter);
    }

    return ;
}

2、根据position查找对象

    actorPosition = (actorPosition + ) % activePlayers.size();
    list<Player*>::iterator iter = activePlayers.begin();
    advance(iter, actorPosition);
    actor = *iter; // Potion对应的Object
    // actor = activePlayers.front();
    // actor = iter.front();
