Hi,

comp.games.development.programming is probably more appropiate for this
question.

Thanks, I didn't know about that group. I will ask the question there.
Still it is programming and I am trying to learn programming by
programming games.

Why? His question was more or less about program logic, using mostly
standard C++ (save for one function). That's more on-topic than many
other posts here.

Bart.

Only the OP should guess which group will provide the best answer.

Posters are entitled to guess, true. But, correcting guesses is the
job of newsgroup regulars, and prefectly reasonable.

The only topicality criteria relevant to a questioner is what newsgroup will
provide the best question. Once we suggestion one, we can no longer declare
whether an equally topical question belongs here or there. That was the
context.

When you offer another newsgroup, always reinforce that topicality is in the
poster's best interests. The answer "your question is off topic here go
away" doesn't increase the odds of useful participation.

I think MY code works. It is a bit more complex and cumbersom than I
would like but I am pushing ahead on next part of the game.

You correctly indicated a good newsgroup. Nobody doubted that.

Except Bart, who claimed you shouldn't have bounced.

I defended you, by saying you didn't bounce, you suggested.

Then Nathan attempted to refute my defense, which he didn't understand.

So I think your thanks are due me, not Nathan. ;-)
