The first one here is a version of Serapth's Game From Scratch tutorial.
Would be nice to put in std::unique_ptr but unsure how to an where.

{
delete p.second;
}
};
};

}

{
_gameObjects.insert(std::pair<std::string,VisibleGameObject*>(name,gameObject));
}
void GameObjectManager::Remove(std::string name)
{
std::map<std::string, VisibleGameObject*>::iterator results = _gameObjects.find(name);
if(results != _gameObjects.end() )
{
delete results->second;
//std::unique_ptr<VisibleGameObject*> temp(results->second); //Have no clue how to use this for here???????
_gameObjects.erase(results);
}
}
VisibleGameObject* GameObjectManager::Get(std::string name)
{
std::map<std::string, VisibleGameObject*>::const_iterator results = _gameObjects.find(name);
if(results == _gameObjects.end() )
{
return NULL;
}
else
{
return results->second;
}
}
unsigned int GameObjectManager::GetObjectCount()
{
return _gameObjects.size();
}
void GameObjectManager::DrawAll(sf::RenderWindow& renderWindow)
{
std::map<std::string,VisibleGameObject*>::iterator itr = _gameObjects.begin();
while(itr != _gameObjects.end())
{
itr->second->Draw(renderWindow);
itr++;
}
}
void GameObjectManager::UpdateAll()
{
std::map<std::string,VisibleGameObject*>::iterator itr = _gameObjects.begin();
float timeDelta = Game::GetWindow().GetFrameTime();
while(itr != _gameObjects.end())
{
itr->second->Update(timeDelta);
itr++;
}
}
Meanwhile this next one is something I was working on but couldn't get some annoying error to go away in.
Was trying to see if vector was any better but I'm having issues scanning through the list and getting things by anything other than a number.

I keep getting some annoying excpetion error anytime I try to use the methods meant for targeting a specific sprite/object.
Any ideas? I know I'm missing something but can't pin down what.
