I got lazy and decided to just install WordPress instead of coding up a site from scratch. Probably for the best.

Set up a new blog at www.piratehearts.com so I’ll be posting there now. Or not. I dunno.

I took an epic five-hour nap, woke up at midnight, played some games, then wrote a long, rambling post about world generation in Spectre Shock on TIGS.

Okay.

Been a while since I posted anything here, but I’ve been maintaining a devlog for a new game over at the TIGForums. As described in the thread, the game is a “procedurally-generated first-person action-RPG, incorporating whatever elements of rogue-likes and ‘Shock-likes’ (System Shock, Bioshock, etc.) make sense.”

I recently adding support for patching to my engine, which has allowed me to keep a playable development version up to date without the need to publish a full installer for each iteration.

So far, this plan has worked out well. The immediacy of being able to push out updates coupled with the accountability of having a publicly visible devlog have kept me motivated so far. Outside of a few TIGS compo games, most of the projects I’ve taken on since Arc Aether Anomalies (back in mid-2008) have been abandoned for one reason or another (mostly overscoped design and art requirements). Hopefully I can actually stick with this one.

Man, it would’ve been awesome if I had heard of simplex noise before I started trying to implement what I was calling “triangular Perlin noise.” Turns out this problem has already been solved…by Ken Perlin, no less. Hurr durr.

On the other hand, I feel pretty good about having come up with essentially the same solution, even if my implementation was specific to 2D noise.

I’m a little curious as to why I haven’t heard more about simplex noise, seeing as it’s been around for almost a decade, and I researched noise functions pretty intensively back in 2006 when I was working on my Master’s project. I just now discovered Stefan Gustavson’s 2005 paper “Simplex noise demystified” (http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf), which provides a nice, clean, legible explanation of how it works and how it differs from classic Perlin noise, with pictures and everything.

I think I’ll take another look at my own implementation tonight and see what I can do to improve it. I know for sure my conversion to simplex coordinates worked differently (I staggered each row in opposite directions, as opposed to skewing all coordinates uniformly), and I recall having some trouble finding a suitable function for summing the contributions of the three nearest gradients, though I may have ended up with the same one used here. My initial approach involved interpolating over barycentric coordinates, which produced obvious visual artifacts; I believe I did eventually land on the radial falloff solution, though I couldn’t say off the top of my head what sort of falloff function I used.

Way-too-late edit: I would be remiss not to include a link to Ken Perlin’s original paper: http://www.csee.umbc.edu/~olano/s2002c36/ch02.pdf

I’ve started working on a web app. The prototype is available at http://www.j-kyle.com/testbed/someapp/. There’s no real functionality yet, but eventually it will be an issue management system.

The motivation for this project was my inability to find a web-based issue tracking app that met my needs. Most issue tracking services provide software that is intended to be installed on a server; I wanted something already set up and accessible to anyone with a browser, and with the ability to allow users to collaborate on issues as opposed to strictly a personal to-do list sort of thing.

PHP and MySQL is turning out to be a breeze. I already have registration, email verification, and login/logout working. My implementation could probably be better, but hey, it’s my first try.

Well look at that. Wireframe mesh displayed on the CRT sim from PinkBunny.

Set up a new project last night based on PinkBunny. Gonna do another retro/CRT game, but this one won’t be for a competition, so with no time limit (but still a relatively small scope), hopefully I can make this one a little more complete. Details and screenshots of tech to come as they are available.

Learning PHP, MySQL, and CSS. Gonna make a new site and do it right this time. My testbed is available here if you want to watch my (lack of) progress in real time: http://www.j-kyle.com/testbed. The goal is to have a dynamically populated list of all my ongoing projects, with a dynamically generated details page for each one, and links to all relevant external sites (LinkedIn, Twitter, WordPress, Toodledo, and so on). Also I’m shooting for XHTML 1.0 Strict compliance, ’cause why not? Gonna work on getting the content available first, then I can spend some time worrying about the presentation. Besides just learning CSS, I also need to read up on good site design and maybe just good design in general. I know I have a copy of the Non-Designer’s Design Book somewhere; probably time to break that out again.

So it looks like Baywords is back up, which means all my old blog entries are viewable again, but now I gotta decide which blog to continue using. Unfortunately, Baywords doesn’t support importing or exporting blog entries, so I can’t merge them into one either way. Lame. Thanks for nothing, Baywords.

I guess I could manually copy each entry over since there were only a handful of them, anyway, but then they’d be all out of order and stuff and I’d have to manually update their timestamps. Rarghrarghrargh.

EDIT! I copied all my old entries over by hand. The image refs still all point to Baywords, which is sketch, but whatevs.
