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.

My program won't open anymore.
Is it showing in the taskbar or is nothing happening?
Close Greenfoot. Open the "project.greenfoot" file of your scenario with a text editor. The last two lines should look like this:
Remove those two lines, save the file and open it with Greenfoot.
xPosition=<some number> yPosition=<some number>
thanks a million.
also I'm creating a remake of plants vz zombies game and I want my plants to shoot at the zombies only when they're present in the same row. Right now I currently, can make the plants shoot but the bullets come out even when the zombies are not on the screen. do you know How i can get the bullets to shoot only when there is a zombie in the same row as the plant?
this is my code
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);
}
}
