+x=usr(1536) Posted October 18, 2022 Share Posted October 18, 2022 23 hours ago, Traxx said: Damn Stephen,tell us what you really think He's basically stating the publically-acceptable version of how I view people who willingly refuse to remain employed. We currently have a dozen individual job openings for a position at my company. Week after week, we see qualified candidates apply then never follow up on phone or in-person interviews. Why? Because filling out two job applications per week is enough to keep unemployment rolling in. Never mind that we're offering above-average pay, flexible shifts, paid ongoing training (a legal requirement to maintain the licensing necessary to do the job), benefits, and long-term stability: apparently, there's more integrity to be had in sponging off of others than making your own way in the world. In any event, this thread is about 5200 programming. It'd be appreciated to see it stay that way, despite yet another 'it's all about me' moment brought to you by Ray Jackson. 4 Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted October 18, 2022 Share Posted October 18, 2022 Thank you for this tutorial series! I've been avoiding assembly most of my personal and professional life. Still, I've gotten to the point where hacking other developers routines on the 2600 is a must. Taught me a lot about DASM and 6502 assembly in the first hour. Will be going through the rest on YouTube. Any thoughts on FastBASIC since they added 5200 support? https://github.com/dmsc/fastbasic Quote Link to comment Share on other sites More sharing options...
+Ryan Witmer Posted October 22, 2022 Author Share Posted October 22, 2022 Back to it this week. This week I focused on the slightly frightening topic of display list interrupts. I also took some time to discuss how to use the other buttons on the controller and demonstrated how to make a pause loop. At the end, I got some enemies on the screen, and next week I'll start working on making them do something. Attached is this week's code and binary. 5200lesson4code.zip 4 Quote Link to comment Share on other sites More sharing options...
Crazy Climber Posted October 22, 2022 Share Posted October 22, 2022 Cool topic! Man, makes me almost want to try something I thought was impossible for me... I doubt I ever will but you make it seem like I maybe could, or at least actually give it a try, and maybe just see what happens... I'll just keep following for now 😃 Quote Link to comment Share on other sites More sharing options...

Cebus Capucinis Posted October 22, 2022 Share Posted October 22, 2022 I tried programming once. I put in HELLO WORLD and it output NO SOLICITING! 7 Quote Link to comment Share on other sites More sharing options...
+Ryan Witmer Posted October 29, 2022 Author Share Posted October 29, 2022 Here's session 5: Got some stuff moving around and shooting, and even got a score display built.

+Ryan Witmer Posted November 5, 2022 Author Share Posted November 5, 2022 Here's last night's video. This week I did some player collision stuff, a little bit of sound, and demonstrated some basic sprite multiplexing. This is as far as I plan to go with this little game project. Final code is attached. I have some plans for Veteran's Day, so there will be no video next week, but the following week I plan to start a new project that will demonstrate some other ANTIC modes that games often use. 5200lesson6code.zip 3 1 Quote Link to comment Share on other sites More sharing options...
RB5200 Posted November 6, 2022 Share Posted November 6, 2022 Will be looking forward to it. Thanks, this stuff is great. Quote Link to comment Share on other sites More sharing options...
+Ryan Witmer Posted December 10, 2022 Author Share Posted December 10, 2022 After a little bit of a break, here's a new episode. Sadly, my microphone decide to cut out at the beginning, but I do fix the problem once I notice it. Starting a new project here to demonstrate ANTIC mode 4, which is very commonly used for games. Doing a simple Tetris clone. Here's the code for this week's video: 5200lesson7code.zip 3 Quote Link to comment Share on other sites More sharing options...
+Ryan Witmer Posted December 18, 2022 Author Share Posted December 18, 2022 More Tetris implementation adventures. Got some basic piece movement and collision detection working.

RB5200 Posted December 22, 2022 Share Posted December 22, 2022 Testing on real hardware and the controls aren't as horrible as you thought they would be, it is pretty easy to over run the piece on move timer 5 though. I adjusted to this, 1- 50 down timer 2- 8 move timer 3- 60 left movement point 4- 160 right movement point these changes feel pretty good, at least up to this point in development. what do think about this, for possible vertical controls 1- down stick speed up down timer by however much 2- up stick instant piece placement 1 Quote Link to comment Share on other sites More sharing options...
+Ryan Witmer Posted December 31, 2022 Author Share Posted December 31, 2022 Here's a new video: Implemented fast drop and piece rotation, but not without some difficulty. There is a bug around rotations at the very top of the pit, I'll probably clean that up next time. Here's the code and binary for this video: 5200lesson9code.zip 4 Quote Link to comment Share on other sites More sharing options...

+Ryan Witmer Posted January 14 Author Share Posted January 14 Made this last night: Got line detection and clearing done for the little Tetris game, but not as cleanly as I would have liked. Either way, this is going to be the end of these videos. I think I've exhausted all the stuff I wanted to cover. I hope they've been helpful, or at least entertaining.

zylon Posted January 15 Share Posted January 15 Interesting stuff. I've been considering trying to port a few games over to 5200, like I did from VIC-20 to C64 long ago. I can already tell there's a lot more to it for A8/5200. Quote Link to comment Share on other sites More sharing options...
RB5200 Posted January 15 Share Posted January 15 Thank you for making these videos and sharing your knowledge. They have indeed been very helpful, I hope maybe someday you'll think of something else to teach and return to this programming series. again, thank you.

+Ryan Witmer Posted January 15 Author Share Posted January 15 Interestingly, the person I was talking to during the stream was @vitoco, famous for his A8 Basic 10-liners. Quote Link to comment Share on other sites More sharing options...
