On number 1, one thought that comes to mind is to iterate through 3D space in blocks, rather than simply randomly generating X, Y and Z values, and deciding whether within each block you will place asteroid or a planet or nothing at all..  Think of dividing the 3D space in the game into 6 blocks along each axis, X, Y and Z.  This ...

Very cool, Matthew, thanks for sharing!  It's a great example and a very polished Phrogram program.  Educational on more than one level!  Here's a screenshot:  

Indeed very clever!  Thanks for a great example, Neil!

Another smiple game for 2 players.

The classic 2-player game of Checkers.  Uses Drag and Drop style of mouse input for moving the checkers.

This game rocks, lol!  Thanks, Neil!  In his own words: I've just uploaded a new program, Space Junk in the "user uploads" section of the "downloads" part of the website (here).I hope it's a reasonable demo of the kinds of things that you can do in Phrogram -- I wrote it to learn the "Phrogram ...

Here's a quick example based on LearningProgram004, Joyce.  Basically, I added a second UFO to the program, move them both, and when they collide I make one of them disappear and the other one grow in size.It sounds like a very fun game - glad to help more as you work on it!

This is cool, TomDad, thanks!  What's most amazing is you did this in about 50 instructions - cool! As Hymake said, it's very hard, because it goes so fast.  I added a 100 millisecond delay to the main loop, as shown here - that's only 1/10 of a second - and now I can actually play it, slow oldish guy that I am, lol!  ...

This is Jamey's "pig latin translator" program - a fun 2D toy example.  Besides its fun use of a graphical background ad, it does lots of fun string manipulation - very important stuff for any programmer to learn.  97 lines of code, in total.  Her post and the download are available here: ...
