My greenfoot file is a game of plants vs zombies and it all of a sudden just wouldn't let me open the file anymore. I can open up my other greenfoot programs but I can't open this one.

Close Greenfoot. Open the "project.greenfoot" file of your scenario with a text editor. The last two lines should look like this:

1 2	`xPosition=<some number>` `yPosition=<some number>`

Remove those two lines, save the file and open it with Greenfoot.

private void shootPeas(int timeInterval)
    {
        if (!getWorld().getObjects(Zombie.class).isEmpty())
        {
            long curTime  = System.currentTimeMillis();
            if (curTime >= lastAdded + timeInterval) //5000ms = 5s
            {
                lastAdded  = curTime;
                Pea pea = new Pea();
                World world = getWorld();
                world.addObject(pea, getX() + 28, getY() -11);
            }
        }
