newbie : help with arraylist
Nov 30th, 2008, 6:31pm  
Hi, (escuse me for my awfull english)

i'm making an interface with points that can be link by lines. At first i used basic arrays like:

 points[] Linelist = new points[0];

and the lines were draw this way :

 for(int i = 1; i < Linelist.length; i=i+2) {
 line(Linelist[i - 1].x, Linelist[i - 1].y,Linelist[i].x, Linelist[i].y);

Actually, i have to change my program and use an Arraylist, but i don't know how to convert

 linelist[i].x

("linelist.get(i).x"doesn't work)

thanks !

In Processing, currently you have to cast the objects taken out of an ArrayList:

points p = (points) linelist.get(i);
then use p.x and p.y
