Vector Crash Course

Q: How do you add/subtract vectors?
A: It is easy, once in Cartesian coordinates. Let A=<a,b> and B=<c,d>. Then A+B=<a+c,c+d>.

that'll confuse somebody, hurry! fix it before some unsuspecting learner hits their head on it!

The most basic use of vectors in script is just movement, many people already use them without knowing it. Whenever you have a direction (i.e. angle, or even built in directions) and a speed (magnitude) you're using vectors. Using dx (delta x or distance x, whichever you say) and dy is also using vectors, cept they don't need translation (sin + cos) to be used on the board.

I'll post some basics in physics if anyone is interested and if Gilt doesn't mind.
