Question

我得到一个“不兼容的矢量迭代器”错误，我认为它是一个无效的迭代器

void Bomb::CreateExplosion(Game_Manager* EGame_Manager)
{
for(irr::f32 iteration = 0; iteration < BlastRadius; iteration++) //up direction blast
{
   ***//PROGRAM CRASHES AT THIS LINE-->*** for(EGame_Manager->getEntityManager()->GetEntityIterator() = EGame_Manager->getEntityManager()->GetEntityList().begin(); EGame_Manager->getEntityManager()->GetEntityIterator() != EGame_Manager->getEntityManager()->GetEntityList().end(); ++EGame_Manager->getEntityManager()->GetEntityIterator())
    {
        if(CheckForCollision(UpExplosion->getTransformedBoundingBox(), (*EGame_Manager->getEntityManager()->GetEntityIterator())->GetEntityNode()->getTransformedBoundingBox()) == true)//check for collision against the unbreakable blocks (entity.type equals 0)
        {
            if((*EGame_Manager->getEntityManager()->GetEntityIterator())->GetType() == unbreakableblock)
            {
                break;
            }
            else if((*EGame_Manager->getEntityManager()->GetEntityIterator())->GetType() == gameplayer)
            {
                (*EGame_Manager->getEntityManager()->GetEntityIterator())->SetLives(this->GetLives() -1);
                break;
            }
            else if((*EGame_Manager->getEntityManager()->GetEntityIterator())->GetType() == gameitem)
            {
                break;
            }
        }
        else
        {
            UpExplosion->setScale(irr::core::vector3df(1,1,iteration)); //standard width of UpExplosion, iterated height of the UpExplosion
        }
    }
}

CreateExplosion由Bomb :: UpdateEntity（）调用，由EntityManager :: UpdateList（）调用，然后循环遍历向量＆lt; * Entity＆gt;列出调用每个实体的相应更新功能。

此函数将实体添加到向量中我不确定它是否会导致问题

EntityManager::AddEntity(Entity* addtoList)
{
    List.push_back(addtolist);
    addtolist->GetEntityNode()->setID(List.size());
    EntityIterator = List.begin();
}

如果对任何事情都有帮助，那么调用这些函数的Bomb类的实例也会在Player类中声明。如果需要，我可以发布更多代码。
