Thank you danpost for letting me know about Greenfoot 2.4 and its additional methods, which version I have now installed. As davmac does rightly remind me, indeed my Turtle inherits from Animal, which inherits from Actor, but these two classes do come with empty Act methods, which startled me somewhat. So I proceeded as instructed in the video tutorials, namely, empty the contents on the Animal class first, then paste the Animal class version 1.0 by Michael Kolling, and it worked. I guess I should try invoke isTouching, removeTouching, and isAtEdge methods in the Turtle class, which inherits

We need to uncomment the correct line in the NativePathSetter class. With s+= "native/Windows64;"; its all ok, when the ball touch the house the LED on Pin 13 ligths Thank You very much!!!

Thank you so much I really appreciate it!

No :D I mean where is the code with which you want to add the scoreboard to the world.

The part 'F = 1' does not produce a true/false (boolean) value. It only sets 'F' to the value of '1'. For comparing two values for equality, you must use the '==' operator ( 'F == 1' ).

It works now! Thank you!

You can still use 'isAtEdge', but you will have to create the code for the method and add it to the class yourself. Obviously, it should have a return type of boolean and you will need to put a check in it for each of the four edges of the world. HINT: check for the 'x' or 'y' values that represent the edges of the world.

It's working perfectly now. Thank you all for the help and advice. Much appreciated, would not have figured it out without you guys. Thanks again!

I am not sure what you mean by this. Greenfoot does not 'play' gif images in itself. The correct Java code, such as that which the 'GIFActor' class contains can be used to run gif image animation. If you have downloaded this class and are using it, there are 'pause' and 'resume' methods in the class, as well as a 'setImage(String)' method you can use to change the gif file used. All you then need is an int field to count the frames as one of the animations runs.

When I

You are already have the conditions to check if there is an enemy (line 37 and line 46). In this if-blocks, you need to call the 'addScore' method on the Counter object. (the part you commented out has to go there)
