Do you want them to alternate shots?? or random decision as to which shoots?? or just seperate keys for each to shoot??
What i plan to do is to make option page and have one level which is two player and have another which the dimentions randomly shoot

I gave you a suggestion (actually I gave you two suggestions) and you said it didn't work. I know that it should have worked, so there is most likely a problem with your code when you tried it. If you post that code, we can help you find the error in it.
here is both of the codes
penival:
dimentions:
port greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class penival here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class penival extends Actor
{
/**
* Act - do whatever the penival wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if (Greenfoot.isKeyDown("left"))
{
move(-3);
}
if (Greenfoot.isKeyDown("right"))
{
move(3);
}
String key = Greenfoot.getKey();
if ("space".equals(key))
{
fire();
}
}
/**
* Fire the penival
*/
private void fire()
{
Bullet bullet = new Bullet();
getWorld().addObject(bullet, getX(), getY());
bullet.setRotation(getRotation());
}
}
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Dimentions here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Dimentions extends Actor
{
/**
* Act - do whatever the Dimentions wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if (Greenfoot.isKeyDown("a"))
{
move(-3);
}
if (Greenfoot.isKeyDown("d"))
{
move(3);
}
String key = Greenfoot.getKey();
if ("z".equals(key))
{
fire();
}
}
/**
* Fire the dimentions
*/
private void fire()
{
Bullet2 bullet2 = new Bullet2();
getWorld().addObject(bullet2, getX(), getY());
bullet2.setRotation(getRotation());
}
}
Ok; I can't really see how this is very different from your code before. My two suggestions were:
For instance, use a variable to keep track of whether the key was up or down last time you checked, and only fire if it was up last time and down this time. Alternatively, you can move the getKey() into a single location (such as the world) and then have it control the other objects depending on which key was pressed
Which of these did you want to try?Well, no, I'm not going to write the code for you; it's important that you at least give it a go yourself. If you make a decent effort, and it doesn't work, I'll gladly help you to correct it.
Perhaps you should go through the Greenfoot tutorials (see the "Documentation" link at the top of the page); seems like you're not very familiar with some of the more basic concepts, and the tutorials would help you a lot (watch the videos!)
i have but i have got the to shoot by it only allow on person to shoot at a time and i want both of them to shoot
