> Another month, another Vulkan progress report! October was a busy month, as most of it was split between working on the new Global Illumination system and Godotcon/GIC in Poland. Despite this, strong progress was made and the new GI system seems pretty much complete.

> Godot 3.0 introduced GIProbes. They provide Global Illumination to scenes. They were, however, pretty limited. Only static geometry could provide GI and dynamic objects were ignored. Added to this, changes in light settings had significant frames of delay. Added to a not so great performance and quality, the feature was barely usable as is.

> For Godot 4.0, GIProbes will see several significant changes, which will be outlined as follows:

> A simple choice for this function is simply the straight-line distance from the node to the goal position – this is what we have been using in Factorio since forever, and it’s what makes the algorithm initially go straight. It’s not the only choice, however – if the heuristic function knew about some of the obstacles, it could steer the algorithm around them, which would result in a faster search, since it wouldn’t have to explore extra nodes. Obviously, the smarter the heuristic, the more difficult it is to implement.

> The simple straight-line heuristic function is fine for pathfinding over relatively short distances. This was okay in past versions of Factorio – about the only long distance pathfinding was done by biters made angry by pollution, and that doesn’t happen very often, relatively speaking. These days, however, we have artillery. Artillery can easily shoot – and aggro – massive numbers of biters on the far end of a large lake, who will then all try to pathfind around the lake. The video below shows what it looks like when the simple A* algorithm we’ve been using until now tries to go around a lake.

> Quest games started with a premise like “escape the wizard” or “escape the aliens” then forced you to do a series of banal and random tasks to avoid the many, many ways to die. Once you know the way, most of the games can be completed in under an hour. On the first go, it took my whole family weeks. Not the least of the horror was often having to do things several scenes before there’s any reason for having done them: in Space Quest I, the hero-janitor Roger has to refuse the first offer for his bike, so the guy will come back a little later and throw in a jetpack. Of course there’s no indication that he’ll come back with a jetpack, and no reason to think there’s a need for a jetpack until three days later when Roger exits his spaceship and floats into the void because he doesn’t have a jetpack. This leads to replaying most of the game a dozen times just looking for a jetpack, which is hidden not in a spaceship closet or a bar or a cavern, but behind a tough-but-not-too-tough bargaining strategy. It also took about ninety seconds to switch between screens, so exploration was grueling on a good day.

> After playing the first two, I realized I’d been programming for 17 years and could probably make my own, especially when all the art is 320 pixels wide and that’s about how many pixels I can work with before people give me a sideways look and ask if I really have a liberal arts degree. I decided to base the story loosely on my novel, for two reasons: first, if the game happens to get the kind of notoriety my novel has not, I might be able to boost sales by claiming the novel can serve as a hint book. Second, I spent nineteen years writing that stupid book, and this seemed like a good a way to manage the withdrawal symptoms. Three weeks later I’d built a rendering engine I’m quite proud of, a simple command and scene logic processor, and accidentally reinvented GIF compression.

> What Remains is a narrative adventure game for the 8-bit NES video game console, and was released in March 2019 as a free ROM, playable in emulator. It was created by a small team, Iodine Dynamics, over the course of two years of on and off development. It’s currently in the hardware phase as a limited batch of cartridges are being created from all recycled parts.

> The game plays out over 6 stages, wherein the player walks around multiple scenes with 4-way scrolling maps, speaking to NPCs, collecting clues, learning about their world, playing mini-games, and solving simple puzzles. As the primary engineer on this project, I faced a lot of challenges in bringing the team’s vision to reality. Given the significant restrains of the NES hardware, making any game is difficult enough, let alone one with as much content as What Remains. Only by creating useful subsystems to hide and manage this complexity were we able to work as a team to complete the game.

> The trend owes its health to an odd array of influences: The youthful fervor and firm dis-Establishmentarianism of the freaks who design computer science; an astonishingly enlightened research program from the very top of the Defense Department; an unexpected market-Banking movement by the manufacturers of small calculating machines, and an irrepressible midnight phenomenon known as Spacewar.

> Reliably, at any nighttime moment (i.e. non-business hours) in North America hundreds of computer technicians are effectively out of their bodies, locked in life-or-death space combat computer-projected onto cathode ray tube display screens, for hours at a time, ruining their eyes, numbing their fingers in frenzied mashing of control buttons, joyously slaying their friend and wasting their employers’ valuable computer time. Something basic is going on.

When he left the newly restricted ARPA he spent a year at Utah decompressing from the Pentagon and then went to Xerox and there continued his practice of finding and rewarding good men for doing pretty much whatever they considered important work. Freedom to explore in the company of talent is an irresistible lure. In two years Xerox had twenty of the best men around working. Toward what? Well, whatever.

> Whether or not a player notices, appreciates, or is able to see these details, everything from a pen on a desk to a chair in a room has to be meticulously made, scrutinized, and tested. But at what cost? How does a developer decide how much time to allocate to set dressing a small room versus a game’s main character? How many polygons should an asset in the corner of a players eye get versus something directly in their face?
