Scaling for idiots

Blitz3D Forums/Blitz3D Programming/Scaling for idiots

Is there another way to scale a mesh that makes a mesh shrink with negative numbers, and grow with positive numbers? Or is there a function of some sort that lets me transform a negative number into a number from 0 to 1?

This is for scaling a mesh according to mouse movement. If someone has done this (which I'm sure someone has), can I please see the code?
