Thanks for the PR! Aside from the one comment, would you also be willing to extend this to also send the player's speed in the UpdateAbilities packet, assuming that doesn't cause any extra issues just so we can eliminate the TODO completely. If it's not as simple then I'm happy to merge this after the type is changed.

Added it, after some tests it seems that the walk speed only modifies the player's fov.
