and everything moves so slow now it keeps lagging
not running smoothly
It would usually happen because there are too many actors in the world (more than you would think). I've seen a scenario with more than 320 different objects in the world at once, and it runs fine. So there is probably a mistake somewhere in your code.
Alright, it sounds like you have a multitude of actors in your world. Give a brief description of what your scenario is about and show the codes to your World subclass (to start with). You may also want to show the codes of any class that create an abundance of actors in the world.
public class Background extends World
{
GreenfootSound backgroundMusic = new GreenfootSound("Background.wav");
private static final String bgImageName = "space1.jpg";
private static final double scrollSpeed = 2.5;
private static final int picWidth = (new GreenfootImage(bgImageName)).getWidth();
private GreenfootImage bgImage, bgBase;
private int scrollPosition = 0;
public Background()
{
super(5000, 400, 1);
backgroundMusic.playLoop();
setBackground(bgImageName);
bgImage = new GreenfootImage(getBackground());
bgBase = new GreenfootImage(picWidth, getHeight());
bgBase.drawImage(bgImage, 0, 0);
prepare();
}
public void act()
{
scrollPosition -= scrollSpeed;
while(scrollSpeed > 0 && scrollPosition < -picWidth) scrollPosition += picWidth;
while(scrollSpeed < 0 && scrollPosition > 0) scrollPosition -= picWidth;
paint(scrollPosition);
}
private void paint(int position)
{
GreenfootImage bg = getBackground();
bg.drawImage(bgBase, position, 0);
bg.drawImage(bgImage, position + picWidth, 0);
}

that is my background
Do the Airplane, Bomb, Robot, Ok, or OKTHEN classes add objects into the world in their code.
(Your code is quite annoying since lines 65 - 66, 88 - 89, 104 - 178 are unnecessary.)
The width of your world is a bit extreme, most screens are only around 1000 pixels wide. You can use code to regulate the size of the scrolling area. I do not think I have ever created a scenario with a window width of much more than 800 or so.

Instead of adding objects at one location then switching it, just place the objects in the place that you want them to be. There are two objects that you add and remove before anything else can happen.There are more replies on the next page.
