Hi im trying to make a score counter for my game, the 'bike' will collect the 'disk' (coins) but im having trouble trying to remove the disk once its collided.
if(disk!=null) <------ says it "cannot find symbol" here as well
{
Arena arena = (Arena)getWorld();
arena.removeObject(disk); <------- says that it cannot find symbol here
Greenfoot.playSound("pop.wav");
Counter counter = arena.getCounter();
counter.bumpCount(1);
}
