Question about vector math functions

Hi Folks-

I need to get the x, y and z components from some of the vectors in my simulation, so that agents can react based only on the value of, say, the x component of another agent's movement vector.

I've read through the manual, and I can't see a way to get these vector component values into int variables using the vector functions provided. I thought I might be able to use matrix multiplication to solve the problem, but I can only think of a way to do this using 1x3 matrixes, not 3x3 matrixes.

I feel like I must be missing something obvious here. Any suggestions?

Thanks!

Jen
