Here is a CHALLENGE for all of you!
I love the game of Bagatelle for here the ball bounces crazily around inside a ring of posts. Its path is utterly PRE-DESTINED yet CANNOT be predicted!
Suddenly it will escape, totally unexpectedly and nobody can foretell when or where.


In this game we have say 39 perfectly elastic immovable posts hammered vertically into a smooth horizontal plane
They are equally spaced on a circle each 1" apart from 2 closest-neighbours
Each post is 0.1" diameter
So between the gaps between posts a 0.8* diameter ball COULD pass.

But our ball is frictionless, perfectly elastic and 0.75" diameter.
We start it rolling within the circle of posts in no specially-chosen way.

Let V(n) be the name of the portion of the path that starts at the nth collision and ends at the next collision.

I maintain there is no formula for V(n)
The path is soon chaotic and the place and time of escape is not computable.

The only way to find out is to actually compute the path impact after impact in turn, from the beginning.
And no computer is accurate enough for that!
For the "bounce off" new direction depends CRITICALLY on where on the post the ball strikes. And that depends SUPER-critically on where the PREVIOUS path began and its direction.
It is a nightmare of chaos and instability. Like a house of cards built with each card more wobbly than the previous card.

The bouncing from convex and concave mirrors is especially interesting in the deign of LASERS, image-producing optics and paths (numbers) that are as near as is possible to "random"

In fact the only situations that any computer can predict are limited to those where the situation is STABLE. Otherwise the smallest errors get magnified and the results soon meaningless. (Soon means after a dozen or few dozen calculations).
But if the situation is STABLE the errors can get corrected - like a ball rattling down a U-section slide or down a valley.

Thanks Axylon. Your site is GREAT for it has high potential - far above the "code only" sites.
Yes of course we want to encourage those already skilled enough to write in Basic, C** etc but we ALSO want to encourage and "light the fire" in those that have iDEAS but do not know where to start

As for me, I don't even know how to "take a screenshot" (What I mean is my brain is full up and I prefer to leave space for new ideas rather than remembering arbitrary syntax).

I am trying hard to get my Grandson Harvey to join and  he is 4 years younger than you so BOTH OF YOU are exactly the right "ideas" age to get a GREAT site running!

ok john, i think that your ideas are good, but if you somehow did this:

No PMs any more. No contact Axlyon
Only email to members

Topics, such as my "Ideas" closed without saying they are closed; leaving us to find out they are closed!

Transferred to "my projects" - there is no such and search cannot find it

Nearest seems to be "Child Boards"
Child boards is ENTIRELY DEVOTED to mere TOOLS (such as QBas, C++ etc etc) and DOES NOT MENTION the IDEAS that MOTIVATE us to WANT to learn how to use tools and get them to HELP us.
You are making the SAME mistake as the failed QB64 site . Talking only of CODE rasther than "what the user longs to do"

You may be the dictator, but you have ENTIRELY FAILED to see that ideas and tools are OPPOSITES.

i can't find where this might have been, or how it could have been sent, but i'm pretty sure that this is running fine. if you wish, send me a screenshot or two, give me some time to get someone with experience running a forum on as a moderator. the reason i dedicated the boards to java, C and BASIC was so people could post their projects in that language in the specific board so  that  i and others could tell what the code was without having to ask. john, i'm only 15. give me some credit for having the patience to create and try to make this thing into a fully working forum! btw john, the "your projects" section is here: http://technogamedevforum.createaforum.com/your-game-projects/    as for the rest i'll ask a friend to sign up and by all means, please take some screen-shots and send them to me with a little bit of proof of this. like i said, as far as i can tell, everything's OK. i'll check the admin center again to see if there's an error report, but this might not show up as easy on my end

EDIT

i just ran a check and the forum can't find anything

yeah john, i was going to mention that, but i forgot since i was doing three or four things at once

right now QB64's not working so i can't test any code. looks good though. a few days ago, when i could test it, QB64 wanted an "=" around here:

m$(4) = "March 2017  Suspect massive comet is approaching"
m$(5) = "October 2017 Radio telescopes detect massive comet"
m$(6) = "December 2017 Government denies  existence of comet"
m$(17) = "Wall Street Panic!  "
m$(7) = "UK and US stock collapse:  Many suicides"
m$( = "Sinners Repent:    The End draws Nigh"
m$(9) = "Computations predict impact with Earth"


can you guys test it so i can make sure i didn't copy the files wrong when i put QB64 on my new PC?
