Weighted Tree

Thanks for adding a weighted tree, It makes me feel safer to know that my implementation does the correct thing. Where are you using it in Wintermute?

Look at this.

In Wintermute I have a single tree for bullet hits, but I have 3 different weighting schemes that concentrate on different types of enemies. Since they all use the same tree I just set the different weights before pulling the KNN. It could be done just as well (and probably a bit faster) by keeping different trees, but I wanted the possibility of adjusting the weights as the battle went on, even though I never ended up using it.

Thanks, I see now you are using one tree to emulate having three different trees with weights.

is chebyshev norm better or worse than euclidean norm for knn
