1) create new world; 2) set values in new world to those in current world; 3) set new world active

As with any scenario, you start in your World subclass constructor. Your world can be either with pixel-sized cells or use a grid of large-sized cells. You would then add code to build the world and add Actor subclasses as needed. Only one subclass of Actor is needed for all gems -- or, rather, the main playing tiles. A field of int or String value, or just its image (which can be given randomly), can be used to identify which type piece the tile is.

You are creating black keys even when there shouldn't be one. Then the string is "" and you can't use "" as a parameter of the isKeyDown method. When creating the black keys, prevent them from creating when the string in the array is "". <Code Omitted>

Each object (from this class and its subclasses) will have its own variable, but all classes can access it.

thanks

Thanks so much @danpost. I understand now. God bless you.

You need to do what you can first and in while doing so, if you run into issues, we help resolve the issues. Do not ask to have others do all your work for you..

I tried moving 'collision' to the end of the act method and it worked Thanks!

Ok, thanks will make sure to check out your demo

You could make use of the 'ask' method of the Greenfoot class. Sample usage might be: <Code Omitted>See the Greenfoot class API documentation for more details.

Thank youu! :D

Okay -- glad to know you are happy with it.

Thx
