Getting The EntityPlayer List

World world = mc.world;
List<Entity> entities = world.loadedEntityList;

public void onTick(TickEvent.PlayerTickEvent e) {

  int i = 0;

  if (i < entities.size(); i++) {
    if (entities.get(i) instanceof EntityPlayer) {
      EntityPlayer targets = (EntityPlayer) entities.get(i);
    }
  }
}
