Hi guys, in my game the Scroller world moves forward when the key w is pressed. also I got an increasing variable rate so the car got an increasing speed til a specific rate. How can I decrease the variable rate and move the Scroller World forwards continously, when I stopped pressing the key w?

Please show your world class codes.

Is the car supposed to stay center screen? and, what does your car's act method look like?

No the car is moving up and down in y direction when it touches the specific color on the Image aof the world, it doesnt move in x direction. 
public void act() 
    {
       
      MovementY();

      
     
      ausrichten(); 
      
      
    } 
    
    public void ausrichten(){                       
        setLocation(wheel2.getX(), wheel2.getY()); 
        
                                                    
        turnTowards(wheel1.getX(), wheel1.getY());  
        
        
                                                    
        move(33);                                   
    }                                               
   
    public void MovementY(){

        for(int i = 0; i < 50; i++){
            if(getWorld().getBackground().getColorAt(getX(), getY()+36).equals(color1)) 
            { 
                setLocation(getX(), getY() - 5); 
                
            }
        }

        
        if(!getWorld().getBackground().getColorAt(getX(), getY()+45).equals(color1) && Timer8 > 1) 
        {
            if(Timer7 >= 1)
            {
                d = d+1;
                Timer7 = 0;  
            }
            else
            {
               Timer7++; 
               
            }
            
            setLocation(getX(), getY() + 1*d);
            Timer8 = 0;
            
        }
        else
        {
            Timer8++;
            
        }

        {
           d= 1;

So, what you are trying to achieve is that the car appears to move forward (to the right) by use of the scrolling. The user controls the apparent speed of the car using key input. Correct?

What you are doing is misplacing the behavior of the car and putting it on the scrolling. It would be better to control the car with the keys, allowing it to be moved along the x-axis, then have the scrolling be determined by the amount the car moved along the x-axis, moving the car back to its original horizontal location. That would be actor follow scrolling code with some ranged actor movement (along the y-axis). See my tutorial on this.
