[英]Erasing a pointer from a vector
I'm trying to erase a pointer to an object, but I keep crashing the console (PS2), I don't get any errors due to the way the console is set up, so I'm not quite sure what is going on. 我正在尝试删除指向对象的指针,但我不断使控制台(PS2)崩溃,由于控制台的设置方式,我没有收到任何错误,因此我不确定发生了什么。
I've listed the two lines that error, this didn't error until I added these lines. 我已经列出了出错的两行,直到我添加了这两行才出错。
for(listIter = m_downDirectionList.begin(); listIter != m_downDirectionList.end(); listIter++)
{
Projectile* proj = dynamic_cast<Projectile*>(*listIter);
if (proj->getZWorldCoord() >= (defaultLevelDepth + zOffset))
{
proj->getPoolOwner()->releaseAProjectile(proj);
//(*listIter) = NULL; // THIS ERRORS, also tried = 0.
//listIter = m_downDirectionList.erase(listIter); // THIS ALSO ERRORS
}
else
{
(*listIter)->update(camera, zOffset);
}
}
What am I doing wrong? 我究竟做错了什么?
Thanks. 谢谢。
EDIT: Clarification, just having this line. 编辑:澄清,只有这一行。
listIter = m_downDirectionList.erase(listIter);
this also errors. 这也是错误的。
for(listIter = m_downDirectionList.begin(); listIter != m_downDirectionList.end(); )
{
Projectile* proj = dynamic_cast<Projectile*>(*listIter);
if (proj->getZWorldCoord() >= (defaultLevelDepth + zOffset))
{
proj->getPoolOwner()->releaseAProjectile(proj);
listIter = m_downDirectionList.erase(listIter);
}
else
{ //m_downDirectionList[p]->update(camera, zOffset);
(*listIter)->update(camera, zOffset);
listIter++
}
}
m_downDirectionList.erase (listIter);
