particle effect

2003-09-06

Hi,
I'm struggling to work out how to generate a random number between -1 and 1. The point being to create a particle effect where particles could go one way or the other...
Any help would be much appreciated.

if you want to chose randomly between 1 or -1 :

ActionScript Code:

var x = (Math.random()<0.5) ? 1 : -1;
 
trace(x);

if you want to chose a number inbetween the range of -1 and 1

ActionScript Code:

var y = (Math.random()*2)-1 ;
 
trace(y);
