The World class has a 'getObjects' method that returns a List object. If the List object is empty, then no instances of the Class provided were in the world.

To answer the question in the title of the discussion, yes. I will use "anvil.png" as the filename of the image. <Code Omitted>Of course, the '50' that was used to reduce the image to half width and half height could be changed to any positive value.

Please post the code in question.

thank you, I love you

danpost please contact patterperson . I am also retired, short on money, and want to interest you in a joint project.

You have helped me a lot. Thank you for your time ;-) I really appreciate your help. thank you again

What type of data needs stored? Is there a specific format for this data? Are you able to create a proper List object or is that what you are having problems with? Of course, all these questions might be answered by just showing what you tried -- in code.

Thank you for your help but I figured it out

Ok! Thank you so much. I'll try and let you know how that goes.

I do not know .. what does it look like right now?

Unfortunately, there really is no easy way to fix this. You need to either determine the alpha part of the track image at all four corners of the car image or use some type of pad intersection method whereby a method is executed on the intersecting pad that determines if the car is on the track or not. Two types of pads would be minimally required -- one for straight-aways and the other for turns. For the straight-aways, the pad can cover all locations the car can be located; for the turns, it can be placed at the focal point of the arc the turn makes (if the arc was allowed to continue aro

...embarrassed! Thanks guys for pointing out the obvious to me! I hope my students don't find this.
