SlidellMan Posted March 18, 2021 Share Posted March 18, 2021 While I was working on my vertical engine, I also decided to make some other demos out of boredom. The first is a horizontal shooting demo, and the second a platformer. The .78b files are included in their respective .zip files. Horizontal Shooter 12-27-2020.zip Horizontal_Shooting_demo.78b.a78 Horizontal_Shooting_demo.78b.bin Horizontal_Shooting_demo.78b.list.txt Platformer Demo 3-18-2021.zip platformer_demo_v01.78b.a78 platformer_demo_v01.78b.bin platformer_demo_v01.78b.list.txt 5 Quote Link to comment Share on other sites More sharing options...

SlidellMan Posted June 24, 2021 Author Share Posted June 24, 2021 (edited) So, I decided to study the firing routines from the Space Physics demo from the bundled examples, and here's the results. As always, if you find something I overlooked, let me know. Horizontal Shooter 6-24-2021.zip Horizontal_Shooting_demo.78b.a78 Horizontal_Shooting_demo.78b.bin Horizontal_Shooting_demo.78b.list.txt Update: I released that the frameCounter variable was ill-suited for what I wanted, so I added in some more variables. Now back to having the shooting work properly. HS 6-24-2021upd.zip Edited June 25, 2021 by SlidellMan Bug problem. 3 Quote Link to comment Share on other sites More sharing options...

SlidellMan Posted June 29, 2021 Author Share Posted June 29, 2021 Now, with a faster firing speed. What I plan on adding next: getting the obstacle to move.

SlidellMan Posted August 11, 2021 Author Share Posted August 11, 2021 Here's a new gravity demo I made. If there's something in the code that I have overlooked, feel free to look into the included file.

SlidellMan Posted August 12, 2021 Author Share Posted August 12, 2021 I wanted to release this sooner, but laziness got the better of me. Horizontal Shooter 6-30-2021.zip 2 Quote Link to comment Share on other sites More sharing options...
+Muddyfunster Posted August 12, 2021 Share Posted August 12, 2021 Ship moves and shoots nicely. I'd suggest a shorter SFX and firing multiple shots causes them to roll up a bit. Nice progress! 2 Quote Link to comment Share on other sites More sharing options...
+Muddyfunster Posted August 12, 2021 Share Posted August 12, 2021 On the gravity demo, i'm not sure what's going on there, but nothing I do causes anything to change. 1 Quote Link to comment Share on other sites More sharing options...
SlidellMan Posted August 12, 2021 Author Share Posted August 12, 2021 I wanted to do simple block dropping, but with one of the two being controlled by the left joystick. You can look at my sources if you want. Quote Link to comment Share on other sites More sharing options...
+Muddyfunster Posted August 12, 2021 Share Posted August 12, 2021 ok, I ran the demo but I couldn't get anything to happen. What should I be looking for? Quote Link to comment Share on other sites More sharing options...
SlidellMan Posted August 12, 2021 Author Share Posted August 12, 2021 I wanted the left block to control like the falling blocks in Tetris and Dr. Mario as a means to make my platforming engine better. The gravity/falling subroutine was based on the included "Ramcharmap" demo. Quote Link to comment Share on other sites More sharing options...
gambler172 Posted August 13, 2021 Share Posted August 13, 2021 The Shooter demo looks good....how about a playable level now? 1 Quote Link to comment Share on other sites More sharing options...
SlidellMan Posted August 16, 2021 Author Share Posted August 16, 2021 That I am trying to figure out, and the platformer demo has a couple of levels in it. Quote Link to comment Share on other sites More sharing options...
SlidellMan Posted August 24, 2021 Author Share Posted August 24, 2021 (edited) Now, for an update of the Platformer demo. It has a total of four levels, and was meant to be a template that used the RamCharMap sample as a reference.

SlidellMan Posted August 27, 2021 Author Share Posted August 27, 2021 Ugh...I finally got the palette on the gem right. However, I am still baffled on how to stop the flickering, to get the platforming tiles to display properly, and how to get the character to also properly display.

+Karl G Posted August 27, 2021 Share Posted August 27, 2021 I only took a brief look, but I can at least say the cause of the flicker: you have "drawscreen" twice in your main loop. Get rid of the first instance, and the flicker goes away. 1 Quote Link to comment Share on other sites More sharing options...

+Muddyfunster Posted August 29, 2021 Share Posted August 29, 2021 at a glance, I don't think you have doublewide on. Will check the source when back at computer. Quote Link to comment Share on other sites More sharing options...
SlidellMan Posted August 29, 2021 Author Share Posted August 29, 2021 I did turn doublewide on, but the title screen text looked horrible with it. 1 Quote Link to comment Share on other sites More sharing options...
Mord Posted August 30, 2021 Share Posted August 30, 2021 alphadata level1 platformer_test_tiles_ramchar extrawide For each of your alphadata maps, add the extrawide keyword at the end of the line. That'll force the plotmap function to turn on doublewide when plotting it, even if you have it turned off for the main program. 2 1 Quote Link to comment Share on other sites More sharing options...
