Is saw this GTA game were a thief steals a car. With button "E" the opbject thief disappeard and you had control over the car.. and when you pressed E again yu get out of the car. I want to us this code for our game aswell.. Which code should i use? Actor -> Thiefs -> civiliancars So by pressing E, you get into the civiliancars but have the same controls as the thief.. please help me..

Here's what I might do: Make them both a subclass of let's call it Control. In control:

public int character = 0;

in Thiefs add a paramater for the character = 0 like so:

if(Greenfoot.isKeyDown("up") && character == 0){
move(4);
blah blah blah...
}

if(Greenfoot.isKeyDown("e") && character == 0 && isNearCar()){
character = 1;
getWorld().removeObject(this);
}

Then have all the controls for the car in thief and when you want to get out:

if(Greenfoot.isKeyDown("up") && character == 1){
move(4);
blah blah blah...
}

if(Greenfoot.isKeyDown("e") && character == 1){
character = 0;
getWorld().addObject(new Thiefs(), getX(), getY());
getWorld().removeObject(this);
}

Does this mean i need to make a new method called isNearCar?.. because greenfoot gives me the message.. cannot find symbol..

Not necessarily, that was just an example boolean. I'm guessing you only want the thief thief be able to get in a car when near it yes? I'd use getOneIntersectingObject(Actor) in a boolean.

public boolean isNearCar(){
    if(getOneIntersectingObject(Car.class) != null){
        return true;
    }
    else{
        return false;
    }

public int character = 0; Do i only put the public int character = 0; in de control class? or also in the thief class and the car class?

I would put the movement code for each in its own class (the car and the thief) because they do not move the same way. Also, I would add a reference to a 'private Thief driver = null;' in the Car class. Have the thief look for a car and, when found and key 'E' is released, get a reference to the intersecting car, set its driver to 'this' thief and remove the thief from the world. When the car is stopped and 'E' is released again, add the driver back into the world and set the driver of the car back to null. The movement code for the thief will not execute while it is not in the world; however, the car is always in the world and its movement code should be restricted by the condition that the driver is not null.

Is this correct? I put a private in character in the class speler == control..

public class Speler extends Actor{
    private int speed = 5;
    public int character = 0;
    public int maxspeed;

the i put the controls in the thief, like so

public class Autodief extends Speler{
    private GreenfootImage dief;
    private GreenfootImage dief1;
    private GreenfootImage dief2;
    private int count = 0;
    private boolean isDown;
    private boolean canSee;
    private boolean foundcollison;
    private int score;
   
    
    public void act(){        
        driver();
        
        
        if (foundcollison()){
          
        }
          if (Greenfoot.isKeyDown ("up")&& character == 0)
        {
            move(1);
            
            if (getImage() == dief1){
                setImage(dief2);
            }else{
                setImage(dief1);
                            }
                    
                   
        }    
          
        
        
        if (Greenfoot.isKeyDown("down")&& character == 0)
        {
            move (-1);
            if (getImage() == dief){
                setImage(dief1);
            }else{
                setImage(dief);
                            }
            
            
             
        }
        
        if (Greenfoot.isKeyDown("left")&& character == 0) 
        {
            turn (-5);
            
        }
        
        if (Greenfoot.isKeyDown("right")&& character == 0) 
        {
            turn (5);
          
        }
       
        if (Greenfoot.isKeyDown("e") && character == 0 && driver())
        {
            character = 1;
            getWorld().removeObject(this);
        }
       
         
              
        }
      
    public boolean driver()
     {
        Actor StolenCar = getOneIntersectingObject(StolenCar.class);
        
        if(StolenCar != null) {
            return true;
        }        else {
            return false;
        }
    }

And for the car.. is used the following control

public class StolenCar extends Speler

What is does now is remove the thief from the world but not switch to control car..
{
   public boolean driver;
   private int character = 1;
   private int score = 0;
   private int speed = 5; 
   private int isingarage = 2;

public void PressKey(){
         if (Greenfoot.isKeyDown ("y")&& character == 1)
        {
            move(1);
            
               
        
        if (Greenfoot.isKeyDown("h")&& character == 1)
        {
            move (-2);
           
            
            
             
        }
        
        if (Greenfoot.isKeyDown("g")&& character == 1) 
        {
            turn (-5);
            
        }
        
        if (Greenfoot.isKeyDown("j")&& character == 1) 
        {
            turn (5);
          
        }
       
        if (Greenfoot.isKeyDown("e") && character == 1 )
        {
         character = 0;  
          getWorld().addObject(new Autodief(), getX(), getY());  
           
             }
         
          }    
        
        }
