我收到一个“不兼容的向量迭代器”错误,我认为这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,后者由 EntityManager::UpdateList() 调用,然后循环通过 vector<*Entity> List 调用每个实体的相应更新函数。
这个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();
}
如果有任何帮助,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。
