Der Ball geht überall ins Tor, wir wollen es aber natürlich begrenzen! HELP!! public void act(){ //player.setLocation(player.getX(),getY()); ball.setLocation(ball.getX() + dx, ball.getY() + dy); if(ball.getY() >= computer.getY() - 25 && ball.getY() <= computer.getY() + 25 && ball.getX() + dx >= computer.getX()){ dx = -dx; dy = (ball.getY() - computer.getY())/2; Greenfoot.playSound("beep.wav"); } if(ball.getY() >= player.getY() - 25 && ball.getY() <= player.getY() + 25 && ball.getX() + dx <= player.getX()){ dx = -dx; dy = (ball.getY() - player.getY())/2; Greenfoot.playSound("beep.wav"); } if(ball.getY() <= 5){ ball.setLocation(ball.getX(),6); dy = - dy; } if(ball.getY() >= this.getHeight() - 5 ){ ball.setLocation(ball.getX(),this.getHeight() -6); dy = -dy; } else if(ball.getX() <= 5 || ball.getX() >= this.getWidth() -5){ if(ball.getX() <= 5){ c++; cScore = String.valueOf(c); read2.clear(); read2.drawString(cScore,2,20); s2.setImage(read2); } else if( ball.getX() >= this.getWidth() -5){ p++; pScore = String.valueOf(p); read1.clear(); read1.drawString(pScore,2,20); s1.setImage(read1); } if(p == 4 || c == 4){ Greenfoot.stop(); } ball.setLocation(getWidth()/2, getHeight()/2); player.setLocation(50, getHeight()/2); computer.setLocation(getWidth()-50 , getHeight()/2); dy = 0; // Codes von anderm Spiel übernommen! } DANKE IM VORAUS!!!!

This is an english webside so you should try writing in english. But however: If I have understood your code right the problem is in this part: 
if(ball.getX() <= 5 || ball.getX() >= this.getWidth() -5){ 
    if(ball.getX() <= 5){

    }
}
You just check whether the balls X location is correct. You also have to check the Y coordinates to make the goal smaler. Otherwhile the goal will be the whole left or right side. Another suggestion: Underneath the text editor you can find a link 'code'. If you want to add parts of your code you should do this using this link because that will make your code look more clear.

Thank you first!! How i can change the code? and here the complete Code.

In line 63, 64 you are just checking whether the X component of the actors location is in a certain area. You also have to check the Y component. So after line 64 you should add some code like this: 
if (ball.getY() > getWorld().getHeight()/2 - 100 && ball.getY() < getWorld().getHeight()/2 + 100) {
    //now your goal has a size of 200 pixels;
}
else {
   //if the ball hasn't reached the goal it should bounce off;
}
You will have to do the same after line 71. If you want your goal to get bigger you have to use a greater value than 100. For a smaler goal a smaler value.
