Vector cross missing

[bootstraponline]

Vector3 has a cross method and I expect one for Vector as well. Pax uses libgdx's Vector2 cross method.

That's a weird cross product method. It seems to be returning just the y component of the cross product.

That could be why Pax renders incorrectly now that I've switched from libgdx's Vector2 to pythagoras Vector.

I think the problem is that you replaced a bunch of calls with libgdx methods that operate on the local vector with versions from Pythagoras that return a new vector. For example:

• facing90.rotate(90).nor();
• facing90.rotate(90).normalize();

The Pythagoras version should be normalizeLocal().

I saw a bunch of similar errors in your diffs.

You're right. Thanks for letting me know.
