THANK YOU IT WORKED

Working in your Cards class code (with the Generation method) above: If you are just trying to give an initial random image to the actor, change line 1 to <Code Omitted>Or, alternatively (if once the image is set, it does not change): remove lines 1 through 5 and change line 6 to the above line.

Generally, yes. Export your scenario to a web page, and upload the resulting files. and is it possible to sell it in any game store? Legally, you need to obey the restrictions of any software licenses that you are bound by. If you export your game using the "share" function from an unmodified official version of Greenfoot then there are no restrictions unless you use the mp3 support, which requires the JLayer library. In that case, read the JLayer license and seek legal advice if there i

do not worry i didnt see you put addObject(light) i left it as New Light() thank you!!!!!!!!!!!!!

Thanks that worked!

Please show what you have tried. Cannot fix unseen code. Use the 'code' link below the reply box to insert code into your posts.

There are many scrolling engines available here. I have several up. My latest one, Easy Infinite Scrolling Support Class, is quite a simple one and easy to use. If you do not have a background image that needs to scroll, it would be perfect (the background scrolling engine of this particular support class 'wraps' the background image; however, the actors can scroll without the background. Another demonstration of its use is in my Wombat Racing scenario.

IT WORKS!! Yes! Thank you again for all your help!

Line 22: <Code Omitted> This creates a variable which can hold a reference to an array, but it doesn't create an array. Nowhere in your code is an array created, so there is no array; 'thisDeck' remains null. When you try to use it, you would get a NullPointerException. You need to initialise the variable with an array: <Code Omitted> (By the way, if you need help with an exception, please post the stack trace or at least say which line you get the exception on! This makes it much easier to diagnose.)

Should they stay private or change them to public? I posted the scenario as well on my profile.

Yeah put them in both, once in the world code, and once in the food code

Like I said, that code was not going to be exactly what you needed. You will have to determine which way to move the ball and move it in the proper direction. Unfortunately, I am short on time at the moment and will probably be out for several hours.

First issue: the 'adjustToGrid' method was created to accommodate square grid-cells. You will need two separate fields, 'gridCellX' and 'gridCellY', instead of the one field, 'gridCellSize' for the dimensions (width and height) of one grid-cell. Second issue (maybe): if the size of your Background world is not at least (1050, 600), then you will have an issue. After removing the declaration of the field 'gridCellSize' and adding in 'gridCellX' and 'gridCellY', you will need to set the value of those fields in your 'createVariable' method. Then change the 'adjustToGrid' method to this:
