    this.addObject( new Ball3(),100,100);
    
    
}
    int Zeit = 0;
int counter = 0;
    public void act() 
    {
           
            Greenfoot.delay(1);
Zeit = Zeit+1;
if ( Zeit==100){
    
Zeit = 0;
counter = counter+1;

}
    showText((counter)+"Zeit",30,40);
      if (counter==30.01){
    this.addObject(new Ball2(),100,100);
    }

From what I can tell, you should only have one spawned every 1.5 to 2.0 minutes. I do not like the use of the delay in your code, but that is another thing ... so, my question is this: What codes are you using in the Ball2 and Ball3 classes?

that one for both

    int dx =3;
    int dy =-2;
 public void act() 
    {
     setLocation(getX()+dx, getY()+dy);
        if (getX()>=620) {
            dx = -dx;
        }
        if (getY()<=20) {
            dy = -dy;
        }
        if (getX()<=20) {
            dx =-dx;
        }
        if (getY()>=490) {
            dy = -dy;
        }

i am making a game named Collosion

Maybe I am not understanding your issue correctly. If you want to increase the time between ball spawnings, increase the value of what Zeit or counter need to end up at.

This. You are obviously missing a basic understanding of your own code which was probably caused by copying too much from other projects. I would advise you to re do it in your way so you know what you are actually doing. The problem mentioned above is the reason for most questions in this forum.
