SkillGrid - new AGA game in the works
« on: November 07, 2017, 05:35:06 PM »
Hi all,

after about 12 years (happily) spent making games for the Commodore 64, AmigaOS 4 and other PC systems, I'm returning to the "classic" Amiga - something I've been itching to do for a long, long time. In the last 10 days or so I have created the core of a new game for standard A1200s - and that's what you can see in this video.

The game, called SPEEDGRID (working title), is going to be of the casual, score-attack type based on the catching/dodging of hexagonal cells representing various bonuses and maluses.

[youtube]https://www.youtube.com/watch?v=69zl4HYAShI[/youtube]

Technical bits shown in the video:
* 3 parallax layers scrolling at a variable speed (up to 16 pixels/frame - such limit is not technical, but only to keep the game playable);
* 1 fixed layer for the HUD (and possibly other graphical effects);
* real transparencies (any color can be freely assigned an opacity value between 0 and 255);
* a 16 colors sprite + a 3 colors sprite.

Things I plan to add:
* occasional meteors zipping by;
* bosses to fight against when time expires;
* procedural generation of the middle layer graphics;
* some "special" music (if I manage);
* any other cool feature that will come to mind.

Note: the current tune is just a placeholder, and it's the fabulous tracker module "Cortouchka" by El Mobo (Frédéric Motte).

Dunno about the player, but, yes, the video you found is exactly the one I posted.

SPEEDGRID - PREVIEW #2

Development slowed down a bit due to work done on other projects and some real-life issues, but it didn't stop.

https://www.youtube.com/watch?v=1og-4VjkbgE&vq=hd1080

This video demonstrates the new features (in particular, the audio engine):
* 3 channels allocated dynamically for one-shot sounds;
* 1 channel allocated for the afterburner looping sound;
* variable afterburner sound frequency, depending on the ship Y speed (calculated taking into account also the scrolling);
* music cell: when caught, music kicks in; as long as music plays, the cells layer is green, meaning that the maluses do not hurt anymore (they award points, instead; the X/Y swap maluses also remove the X/Y swapping);
* music in the form of a 14 bit PCM sample, played at ~28.9 kHz;
* the new way that the BRAKE cell works (before it brought the scrolling speed to the minimun, now it halves it);
* the new BOOST cell (it doubles the scrolling speed);
* slightly different color scheme;
* other minor changes.

Notes:
* music requires two channels; while playing, the other two channels can be freely used for other sounds;
* music playback supports looping (not demonstrated in the video; will be used during bossfights);
* the afterburner sound is off while music plays to allow enjoying the music better and leaving a channel free for the more important events-related sounds;
* the afterburner sound volume is kept low so that it does not become annoying;
* the music is a temporary placeholder; it is an excerpt from Multiball by Machinae Supremacy (a cover of the Pinball Dreams tracker module by Olof Gustafsson);
* despite the high quality of the original video, the compression applied by YouTube causes the quality to degrade steadily after a key frame and until the next one is reached (I guess); anyway, when key frames are displayed and/or the scrolling isn't too fast, it is almost possible to see the actual graphics (especially in the last final seconds).

I assume he means this one:

Uploaded to YouTube the same day as the first post was made.

People always gotta try to do weird things, embedding photos and videos into their posts instead of just putting a link or using the standard forum attachment tools, blahblah, #grumpy.  :lol:

Guys, the links in the posts were correct, but for some reason the player doesn't work. Previous post fixed.

For more information, please check out this other thread (somehow the discussion moved there, and I've realized it only now).
