Download: Spider Stampede
• I started to convert the QB64 example, but decided I could write something better using the built-in PureBasic commands.
• Some algorithms were used from the original source: https://qb64.boards.net/thread/98/explosions.

Additional Features:
1. Move the mouse cursor (crosshairs) over any spider to kill it; spiders will also kill each other.
2. Press the Spacebar to toggle Frame Rate between 30 - 60 FPS, increment by 10.
3. Press the Enter Key to take a screenshot; saved to the root folder.
4. Press the Esc Key to exit.

Hi JHPJHP,

i've tested it with Windows PB 6.12 x86 & x64 - but there is allways only a black screen?

Very nice! Thank you

Updated: Spider_Stampede.pb
• Switched from the C-Compiler to the ASM-Compiler.
• Added a camera-flash effect when taking a screenshot.

Hi dige,

Thank you for posting your results.

I've looked into the example returning a black-screen and may have found a PureBasic bug, but I still need to do some testing.

Hi mrbungle,

You're most welcome, thank you for taking the time to post.

After kill 1000 spiders (one bite me)
Work perfect here in 32 and 64 bit, PB 6.01 and 6.12.
Very nice demo!! Thanks for share.

Love it! Thanks for posting/sharing.

hmm, too bad.I still see only a black screen. When I comment out #PB_Window_Invisible, I see a crosshair and spiders on a black screen.

Hi minimy,

Nice job killing spiders, but you can never get them all. Thank you for testing the code.

Hi BarryG,

I'm glad you enjoyed my Spider Stampede example, thank you for commenting.

Hi dige,

I'm able to consistently reproduce the black screen using the steps below; I'll keep investigating.

If I reboot my computer, open and execute the Spider Stampede example I get a black screen, but only once. If I execute the example a second or more times, no black screen. If I reboot my computer, open PureBasic and execute another Sprite example first, then execute the Spider Stampede example second, no black screen for either example. I've done this numerous times to the same effect.

It seems that DisplaySprite(#SpriteMain, 0, 0) does not work on my system.

In the debugger I can see that the sprite #SpriteMain contains the desktop image.

Could be the screen resolution of 2560 x 1440 is too high?

Black window for the post 1's code

@dige
In my case, I added the line ClearScreen(RGB(0, 0, 0)) after FlipBuffers() and it looks fine.

@breeze4me thanks, now works here.

@JHPJHP very nice code!
Thank you!

Hi dige, Otrebor,

I believe this to be an old PureBasic bug; a few years ago, some of us were having trouble with various sprite examples working with the latest version of PureBasic (at the time). I believe it was Fred who suggested we switch the compiler subsystem to directx9.

Would one of you mind downloading the code again and confirming the problem has been fixed.

Coincidentally (probably not), the examples I previously had trouble with were also full screen sprites; I'll probably post them next.

@JHPJHP yes, the new version works fine.
Thanks for sharing!

Hi Otrebor,

Thank you, your time is appreciated.

Hi All,

Well, that was a bit of a rough start, but enough people seemed interested to keep going.

Download: Jump Sprite
• As was mentioned in my previous post, these were two of the full screen sprite examples that had issues before adding directx9.
• The examples were originally written because some of the games coded in PureBasic (at the time) implemented awkward jumping.
