Armor mechanics won't work. They can't, unless you want your game to freeze up every 10th of a second.
For that to work, you'd have to have a constant "check" on the armor angle and slope. Where the shell is coming from? How fast is it going? What is the armor thickness (in mm).
Blockland, no, torque itself isn't quite equipped to handle calculations of that magnitude while being able to constantly send information back to the server which players are playing on.
