Hey, glad my thread is getting you guys outta the woodwork. And don't worry....we were all newbies once. Well, maybe not Thomas.

Glad to hear my other docs are findable and uaeful when you websearch. Also glad that the cookbook, even in its languishing unfinished stage, is helpful...hearing that might be a bit of a kick in the pants to get more of it finished. > I have a few questions, actually, so if anyone has any thoughts...

Damn, I thought I had worked up an explanation of skipdraw in the cookbook... not that I did a great job of understanding it. to answer your question, I'd say it's VERY likely that you should have the upsidedown bitmaps....ROM space is relatively cheap compared to time, and you'd probably have to have different kernals for all the cases -- both players rightsideup, both upsiddown one down one up, one up one down. As a rule of thumb, adding in more complexity around choosing a loop or whatever is going to be costly. (On the other hand, mirroring is relatively cheap if you're only doing one thing with that player graphic, so you don't need to flip it that way) > But what do you guys think of it so far?

Maybe let the players select > different ships with different properties (notice, all the ship's > flight dynamics are in variables - easy to change!) I'm a big fan of star control myself. Obviously a lot to chew on, at least if you tried to make the ships have different offensive or defensive characteristics. Here's an idea for another way to take this, something I've been toying with trying: Intellivision had a version of biplanes in their "triple action" that was pretty nifty and they say ate up a lot of developer's hour in playtime...so much so there was a joke memo ordering everyone to delete it from their drives. I FINALLY got it for GameCube ($15 Intellivision collection) but havent yet REALLY tried it against someone....still it seems cool. It's like Combat biplanes but with gravity. I think the idea is that "thrust" is constant, but it's not as strong as gravity, so if you go straight up you stall--you have to climb gradually, but you can still do loops and stuff.. Both players start on the ground, and then have to manuever around, both trying to hit the other player, avoid being hit, but even maintaining speed so as not to come crashing to the ground is part of the challenge. There was also a balloon in it players could shoot for points. Of course, to make it REALLY neat, it should ideally have a rough AI to fight against, which might be super tough, or easy if you can think of good tricks. > So, hello! Hi and welcome and I'm so glad to hear some anecdotes of the stuff I wrote being useful...and don't worry, even though I tried to distill what I do know into a form to be useful for others and my future self, I'm still one of the dumbest guys here when it comes to 6502 programming. --Kirk Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://stella.biglist.com
