Oh, duh, here's how. Roll damage dice according to my scheme. 6s hit you. 4-5s hit your obstacle. 1-3s become velocity anew: you end your go up against the obstacle, with your vector marker 1 away for each 1-3 you rolled on the damage dice. If you broke the obstacle, your vector is along the same line it was; if you didn't, your vector's along the angle of reflection.
