Added New - Fully Functional Screensaver with source using my animation technique!
Also added one more new demo - Geometry.
Flickerless, Smooth Animation using pure VB with No OCXs, DLLs, ASM or DriectX. Pure VB. This Entry gives you the code that I created and have used in all of my screen savers for years. The code included is pure VB code (with just a few APIs declared and utilized).
Most of the code is in the "CodePage.Bas" module. This contains all of the initialization, variable definitions and declarations and animation code. If you like it, give me a vote or two.
If I get votes, I'll know you are interested and I'll create a complete documentation package around this.
Demos included are...
Demo_BouncingBalls.exe - About 30 colored balls bouncing all around the screen (Source included).
Demo_BouncingSantas.exe - Bunches of little Santas practicing thier jumping for the upcoming holiday season.
Demo_Geometry.exe - Bunches of geometric images floating around the screen.
Demo_UFO_ScreenSaver.Scr - Aliens have taken over your desk top.
All Demos have full source code in zip format.
UFOsaver.scr - A complete, fully functional screensaver using my animation techniques (source included)!!!
Thanks. Doug Puckett ( dpuckett@thelittleman.com )

Very smooth. Good job.
One small problen: when the screen is 1024x768 or lower works fine, at 1280x1024 or higher the sprites that bounce the highest(off the top of the screen) don't erase completely.
Like this: starting at the bottom of the screen the bottom half of the sprite is not erased, next higher postion a little less than half of the sprite remains and so on. On the way down the closer to the bottom of the screen it gets the more of the top of the sprite remains.
If you could please let me know why this happens.

Very smooth! I guess we will need to learn this sort of stuff now, since the latest version of DirectX seems to have forgotton what 2D is :)

Santa's bobbles sometimes stay on the screen. But I don't seem to have the high resolution problem the other guy does. :-) (I'm running 1280 x 1024).

Anyone that may have had a prolem with resolutions of 1280 or higher can now download the code again. Yhe code has been adjusted so the higher resolutions are fine in the demos. I have also added another demo and a screensaver as extra examples. Let me know if you need anything more. Thanks to all for the interest. I will write a tutorial around this soon. Again, Thanks!

If I set the gravity number (-0.5) to any higher, the pieces leave bits of themselves on screen. Maybe it is impossible to move an item more than 1/2 it's size without leaving bits of it hanging about. Is there a fix for this?
Excellent code!!!! Lots to learn from this one. I just need a couple of years or so... yeah, right after I win the lottery!

Thank you

I was just going over the code for the bouncyballs demo - Very clean and well written. I would highly recommend this to any beginner or intermediate programmer as a good example of well documented, solidly structured code. Thank you for this submission. 5 globes.
