ArrayList of objects and splice
Dec 13th, 2009, 8:51am  
I cannot seem to get an ArrayList of objects to splice in new objects. I think it's just a syntax thing. I am trying to maintain a list of active players and a wait list. I want to be able to pull any player out of playerList by offset and append to the waitList. Order matters in playerList but It doesn't matter on waitList so I can do a simple append. I've tried splice as Player object and I also tried converting to an ArrayList as seen below. I can't seem to get either to work.

Can anyone shed light?

Object code:

Quote:
class Player
{
  String name;
  String img;
  int status;
  
  Player(String s, String t, int b)
  {
    name = s;
    img = t;
    status = b;
  }
}



Code:

Quote:
ArrayList playerList;
ArrayList waitList;
ArrayList tmpList;
 
void setup()
{
 size(400, 200);
 frameRate(30);
 playerList = new ArrayList();
 waitList = new ArrayList();
 tmpList = new ArrayList();

 playerList.add(new Player("Kahlan", "Kahlan.png", 0));
 playerList.add(new Player("Thunderstroke", "Thunderstroke.png", 0));
 playerList.add(new Player("Bellis", "Bellis.png", 0));
 Player tmp = (Player) playerList.get(1);
 playerList.remove(1);
 waitList.add(tmp);
 
 Player tmp2 = (Player) waitList.get(0);
 waitList.remove(0);
 tmpList.add(tmp2);

/* This is the non-working bit
 playerList = (ArrayList[]) splice(playerList, tmpList, 0);
 */
}

void draw()
{

 fill(#ff0000);
 
 for (int i=0; i < playerList.size(); i++) {
   Player p = (Player) playerList.get(i);
   println(p.name);
 }
}

The splice() command works with arrays and you are using ArrayList.

ArrayList has a modified version  of the add

Code:
myarraylist.add(pos, myobject);


Where pos is a valid position in myarraylist and myobject is the thing to insert.
