Thanks Chris

I pick up tips studying your code. Functions inside a Sub? Does it matter? And returning points and arrays, don't see that with QB64 nor drawpoly with or without filled option. :)

Hi Chris,

I am trying to translate a Hexagon Minesweeper Game from QB64 and it seems that PAINT to a border is flooding screen whereas PAINT without border will fill hexagon OK, is there a known bug with using the border color option? I think I tried both RGB and regular QB colors for border color.

Also, I look up PEN() from Help and there is nothing about crucial Mouse polling ie what are the Pen options available? Also PEN ON/OFF the only help given is no longer necessary as I recall? Really needs better documentation. SmallBASIC forum says well here is the shot

and the not so helpful one from github

Looks amazing. But you know what would be even more awesome... your particle explosion code instead of Kaboom!

I will try and fix up the PEN docs soon. I'm not sure if there's a bug in PAINT, I will have a play and see.

I'm making a minor update to fix my stupid keyboard handling issue (I see you've left some notes in the other thread).

Hi Chris,

Well you are consistent, you had same comment a couple of years ago for regular Minesweeper.

I don't know how much time you have to play around with things but increase arrDx say to 20 or even 15 and the thing errors out easy. Since it loads pages with "error", I assume it is a stack problem which is odd because regular Minesweeper could handle much larger game boards...

By popular demand (twice now from highly respected coder), I will look into exploding game boards.  ;)

Here is some more modifications for Minesweeper with explosion of board and sound effect. Man I only found one wav file that would work in SmallBASIC, fortunately it was the most important one. I have also adjusted the mine field to fill your screen with cells based on your systems xmax, ymax settings.

Update: See next reply for two explosion versions in attached file.

OK that was one way to do explosions, here is another, better way, except in SmallBASIC it is sort of in slow motion. Remember when the 6 Million Dollar man use to run?  :))

The attached .zip contains the SmallBASIC source code for 2 explosion methods plus .wav

Nice, I still think it would be good if there was a way to make the same code work in both environments, something like this:

Code: [Select]

#!QB64

... QB64 syntax

#!SB

... SmallBASIC syntax

#

... interoperable code that already works in both systems

I liked this so much I took it back to QB64 and really blow up the board!

Nice, I still think it would be good if there was a way to make the same code work in both environments, something like this:

Code: [Select]

#!QB64

... QB64 syntax

#!SB

... SmallBASIC syntax

#

... interoperable code that already works in both systems


Well they both branch from same tree QB45 or so but QB64 is developed and compiled in C+ with Open GL for graphics package and SmallBASIC going down another path...

Qb64 sure could use SmallBASIC's array tools! and would be nice not to have to worry about TYPE's.

Hi, I have a question. What is SmallBASIC's another path?

SmallBASIC is developed in C and graphics package is either SDL or FLTK with the one original developer still active after all these years, whereas a trio or more have picked up the ball with QB64 and continue to carry it forward into the future.

Both can still run original QB code, can VB do that? :) would we want it to? ;-))
