Remove this from your PongWorld class: <Code Omitted>Your two 'addObject' lines for adding the paddles in the PongWorld constructor should look like this: <Code Omitted>In your Paddle class: <Code Omitted>Also, in the Paddle class, change your act method to this:

This is what I meant: Change line 37 to: <Code Omitted>

This should have been a hint.Declare the field outside the method. Usually, they are placed at the top of the class code. Please refer to Overview: Subclassing in Greenfoot.

Thank you man .. its work now
