I dont know how to get it started, the only things ive done are the basics which is making the character moves & making the pictures. Its a fighting game im doing in my school. My partners and i are having troubles starting on it. I have 4 players (captain america, ironman, black panther, and hulk) and i want to know how would i click on on the pictures i have them on, onto the world aka the map. Idk if i can send the project here for anyone to figure it out but yeah, Please help me out.

Okay, so you will need 4 objects that each depict a different type player for the user to choose from by a click on one of them. Group them in a field array: 
private Actor[] icons = new Actor[4];
This basically assigns a value to each of the icons by its position in the array (the index). The icon objects can be simple Actor objects whose images are set to the various player images. I would use a simple Actor subclass as follows: 
public class SimpleActor extends greenfoot.Actor {}
(that is the entire class). Here is an example of setting up an actor: 
icons[0] = new SimpleActor();
icons[0].setImage((new Ironman()).getImage());
That is just one way you could set the images. Do similarly for the other three, just bump the index and use a different player image. Finally, check for clicks on them in the act method: 
int selection = -1;
for (int i=0; i<icons.length; i++)
{
    if (Greenfoot.mouseClicked(icons[i]))
    {
        selection = i;
        break;
    }
}
if (selection > -1)
{
    // prepare game world here
}

public selection() { // Create a new world with 600x400 cells with a cell size of 1x1 pixels. super(711, 400, 1); } public void act() { //if(Greenfoot.isKeyDown("n")) Greenfoot.setWorld(new map()); } public void keyCommands() { } // public void prepare() // { // for (int row=0; row<getHeight(); row++) for (int col=0; col<getWidth(); col++) // { // Actor actor = null; // while (!canPlace(actor, col, row)) // { // int which = Greenfoot.getRandomNumber(4); // if(which == 0) actor = new ironman(); // if(which == 1) actor = new captain(); // if(which == 2) actor = new blackpanther(); // if(which == 2) actor = new hulk(); // } // addObject(actor, col, row); // } // } thats what i have for my selection, which you can see idk what to get it started

Try this: 
public static Actor player;
public Actor[] icons;

public selection()
{
    super(711, 400, 1);
    prepare();
}

private void prepare()
{
    GreenfootImage[] images =
    {
        (new ironman()).getImage(),
        (new captain()).getImage(),
        (new blackpanther()).getImage(),
        (new hulk()).getImage()
    };
    icons = new Actor[images.length];
    for (int i=0; i<images.length; i++)
    {
        icons[i] = new SimpleActor();
        icons[i].setImage(images[i]);
        addObject(icons[i], 89+178*i, 300);
    }
}

public void act()
{
    if (!Greenfoot.mouseClicked(null)) return;
    int selected = -1;
    for (int i=0; i<icons.length; i++)
    {
        if (Greenfoot.mouseClicked(icons[i]))
        {
            selected = i;
            break;
        }
    }
    if (selected != -1)
    {
        switch (selected)
        {
            case 0:  player = new ironman(); break;
            case 1:  player= new captain(); break;
            case 2:  player= new blackpanther(); break;
            case 3:   player= new hulk; break;
        }
        Greenfoot.setWorld(new map());
    }
}
The map world will have to get the character: 
Actor player = selection.player;
