Thank, Clint, for the ideas, encouragement and book.
A few years ago I had a wonderful time making my first real GUI program, and to
a large degree it was successful due to this group's help.
I've been thinking that I could just include a small "language" in the program
which would translate the "code" into its Unicon equivalent.

Regarding the scrolling of the screen, while it is possible to render the
entire scene in a gigantic hidden window offscreen, and then copyarea with the
current x,y offsets to fill the current visible window with a rectangular
subregion of the full scene, it is moretypical for these applications to
represent the full scene using a data structure, and draw the screen by walking
through the data structure, rendering only those items that appear (or
partially appear) within the window.
Feel free to ask followup questions. I kind of need to add a side-scroller
example to my game book.
Cheers,Clint

Subject: [Unicon-group] Creating a maze game I would like to create a game for
some grandsons: Something that would include typical maze elements (walls,
barriers, traps, jumping platforms, etc) and would allow them to enter in
"code" to create or modify some of the elements.
It would be hosted on a Windows 7+ platform (platform-agnostic would be better
for me) and would be coded in a lisp-family language (CL, Scheme, Racket, Arc,
Logo, etc), Unicon and/or JavaScript. I have been learning CL and Scheme, know
a bit of Arc and Logo and a bit more of Unicon and JavaScript.
While I have been a medical information systems programmer for most of my
career, it has been focused on CRUD (create/retrieve/update/delete)
applications and interfacing (HL7 and proprietary). I have virtually no
experience with GUI and audio applications.
Here are some questions that have occurred to me:1. Which languages would be
best?2. Which toolkits would help? OpenGL?3. Can this be done on a
browser?4. How does one control scrolling in different directions? Do you
create the screen in memory and then instruct the system to scroll in the
direction of the newly created portion?5. Could you interface with one of the
available free game engines?
Obviously this would not have to be world-class. Just something a 10 and 12
year old might like and perhaps from which they could learn how to do some
elementary coding.
Regarding Unicon, I would like the ability to put in code during the play of
the game -- like eval() in other languages -- and wonder if that is even
possible in Unicon.
I would appreciate your input.
Thanks, Steve
