This sounds silly but how can I usee the RND function to generate a random number between -1 and 1? Instead of 0-1?

Only integers or do you need float point?

Thank you spicypixel and erico,

For float I did this:

Code (glbasic) Select

LOCAL r# = (RND(20)*0.1)-1 // Genereates random numbers from -0.9 to 0.9
