C++ unordered_map using a custom class type as the key

http://stackoverflow.com/questions/17016175/c-unordered-map-using-a-custom-class-type-as-the-key

every distinct key i.e. it needs to be able to deal with collisions so it needs a way to compare two given keys for an exact match... value for the entire object. For good performance i.e. few collisions you should think carefully about how to combine the individual.. above defining a good hash function is important to avoid collisions and get good performance. For a real good one you need to take..

Why do people use __(double underscore) so much in C++

2D Platformer Collision Problems With Both Axes

http://stackoverflow.com/questions/2656943/2d-platformer-collision-problems-with-both-axes

of the tile. My problem is that if I check for horizontal collisions first and the player moves vertically at more than one pixel.. it does it for the horizontal axis. How can I handle collisions on both axes without having those problems Is there any better.. to their demo stuff After applying movement it checks for collisions. It determines the tiles the player overlaps based on the player's..

How to generate a LONG guid?

Then when you check the collisions for node A you proceed like this current node root node check.. node A you proceed like this current node root node check collisions of A with each element directly in current node if A can be..

Have a good hash function for a C++ hash table?
