X-Troll Demos - SpriteMagic
SpriteMagic (1989)In spring of 1989, we visited the "Hobbytronic", a computer fair in Dortmund (Germany). The Hobbytronic had it's best times in those years. We always bought computers and electronic-stuff directly on that fair and it had been the best place for having a glance at new hardware. It was the time after the 8 bit age, 16 bit computers and consoles arose everywhere with new and advanced features. For example the NEC PCengine was presented on that fair, and I was amazed by the games Dynatex showed on that tiny console. While walking around the fairgrounds, we accidentally met Marc Rosocha and Klaus-Peter Plog (Plogi / Blue Devil) from the Gigabyte Crew. As I realized that they were talking about an Atari demo, which was displayed on a monitor. I addressed them and asked some silly questions. (I had not done a real program on the ST at this time.) Everything was rather new and interesting to me, and as I figured out that these guys were coders from the Bladerunners, I was really amazed. While we talked, Sunnyboy and Nexus 6 joined us. They watched the demo Marc had coded and decided to do this little demo right after the fair.
It had been inspired the demo Marc showed us, he displayed something about 60 sprites in one VBL. Sunnyboy and Nexus 6 wanted to beat that record, but it wasn't that easy, because Marc's routines where already optimized very well and nobody thought about generated code at this time.
Finally they had done one or two sprites more than Marc, which was not very impressive. To make it look more, they coded a demo that showed 120 sprites in two VBLs. Not one of our brightest ideas. Marc recognized the cheating immediately despite we had used slow movement for the sprites to cover this fact.
Anyway the SpriteMagic demo was saved to disk together with a new version of our scroller, which had been done before the fair, we only changed the scrolltext. If you want to see this demo make sure you use TOS 1.0 and exactly 1 MB of RAM, otherwise you will see nothing, because of some "optimizations" in screen flipping which only work on a one meg machine ;-) -=: Leave a comment at Pouet :=- © 1989 X-Troll
