Demo in PB?

Joubarbe · Post by **Joubarbe** » Wed Jan 21, 2026 11:18 am

Has anyone ever done a demo in PB?

For my next game, I'd really like to have an old-school demo that were used in the past (prehistoric times) to present the group that has cracked the game. And usually you had several games on the disk, so you had a menu to choose which one you want to play. Of course, it came with a trashy chiptune music!

I'm looking for source code if anyone has that. Or someone to commission

Not me but someone has done in PB to pouet.net

See this link here : https://www.pouet.net/prod.php?which=66427

It is a bit old though

Enjoy !

Uhuh, yeah... Thanks

Let's just say that Razor1911 had better ones on Atari ST 30 years ago

I really thought the user xperience2003 in the German board had done such stuff. I was able to find him at pouet here: https://www.pouet.net/user.php?who=10329
But his only demo is only available as an executable, so I am not sure if this was written in Purebasic.

Thank you miso; simple, but very cool!

Interesting effect. Looks good, but unfortunately, it comes from the sprite intensity bug I think. Did not expected this.
I'm on windows, this might behave differently on other OS-es.

Edit: I'm stupid

Wow!! Fantastic demos!

They have transported me back in time.
Very nice examples of the 2D power and old school coders.
Thanks for share and for include minimy in the text.

It is an honor to be on the same list with all these great programmers, thanks miso!!.

@miso,

Very nice old skool effect.

Only the first example works for me on Linux (PB 6.21 LTS at the moment).

I kept watching the names scrolling and was surprised to see mine on there!

Moulder.

I would include everyone here, but I had to stop somewhere...

@Minimy, moulder61, Joubarbe: Thanks, I'm glad you enjoyed

Me too greeting to miso and thanks for sharing !

Thanks!

@moulder61: The third might work on linux, if you remove the commentline ";" before the clearscreen(0) line.
