Setting an object directly right of a player

The cross product of two vectors is one perpendicular to both, so that of the forward vector and 0 0 1 would be to one side of the player - I don't know which side but should be the same right/left hand each time and easier than the trigonometry.
vectorCross("0 1 0","0 0 1") = "1 0 0" (+Y and +Z -> +X)
vectorCross("1 0 0","0 0 1") = "0 -1 0" (+X and +Z -> -Y)
vectorCross("0 0 1","0 1 0") = "-1 0 0" (if you wanted to generate the opposite hand direction, swap the arguments or scale the vector by -1)

I figured there was a better way. The if statements are easier to understand, though, which might benefit elm more.

Thanks spaceguy, i'll try that out later.

Did you actually write that code, or was that adapted from something?
If you wrote it, I have a new found respect for you. Hell if I understand trig of that level.

I actually did write it <3
Logic/math is one of the few things I'm good at, and manipulating bricks through script is the second best.
