Didn't Do Shit

As expected, development this month took a back seat to shit getting hectic at work. A bountiful (read: pain in the ass) honey harvest and my recent discovery of Reentry didn't help. Honestly, I don't think I even opened Unity once.

So it goes. I'm getting pretty good with the Gemini capsule, and the old school NASA cockpits are probably flavoring Black Road Sky in a way that I won't regret, but if I can claim to have made any progress, that's about it.

If you're enough of a nerd to be upset about this, then you should be enough of a nerd to accept my custom Gemini mission pad as an apology.

Back at it soon, hopefully!

Boldly Going Where I've Already Gone Before

As (sort of) promised, I did manage to work on system scale & close range physics this month, but just barely. System scale is working, but the close range physics was honestly wonky as hell before and I'll need to take my time getting it right this time around.

Lots of other shit to talk about this month as well, but the TL;DR is that everything's going pretty damn smoothly.

Attitude Stabilizers

The gyroscopic stabilizer system is pretty much complete & in final form. It mostly works the same way as before, with the main difference being that the system is now breakable, fixable, and upgradable.

I've added an auto-stabilization feature which will be available from the cockpit, with independent toggles for all 3 axes. I think this could be useful for docking, and some pilots might find it convenient to use full-time.

The ship can only be stabilized in this way on any given axis if it's angular velocity is less than that of the flywheel's saturation velocity, which will vary depending on the installed model of stabilizer, but overall it means that attitude stabilization has been significantly nerfed. You can no longer just hold tab to bleed off arbitrary amounts of rotation. To make up for this, I've added an RCS-based auto-stabilizer as well. Of course, this will use fuel, but it should be helpful for managing wild post-collision spins and the like.

Propellent System Hardware

Prop System Diagram

Virtual implementations of the various bits of prop system hardware are in place, with the exception of the utility dock & refuel valve. The rest of the engine room equipment that you can see in the diagram above is all working, and will have player-interactable entities after I reimplement the first-person scale.

The manifold can be used to choke or open fuel flow on individual outputs, pump power can be adjusted to balance thruster power against efficiency and wear damage, and injectors can be adjusted to similarly affect thruster response. All of this only half makes sense, of course, and is geared more toward gameplay than accurate simulation.

Some of these adjustments will only be available from the engine room, but a few important ones will have cockpit controls as well. For instance, there will be an overall RCS pump power selector as well as an RCS injector on/off switch in lieu of the old docking mode button for fine maneuvering control.

System Scale & Related Sidequests

There is once again a vast solar system to explore, so that's cool, but it's just 2 different colored cubes a few billion kilometers apart from each other, so that part could use some work still. There's somewhere to boldly go, anyway.

This was a pretty simple task that boils down to implementing a floating origin, but I took a couple of detours along the way. In order to test the system I needed a way to find distant objects & a way to keep the camera on the ship for the journey, and instead of throwing together quick temporary solutions I decided to build out the base of the sensor system and implement a new & improved chase camera.

The chase camera has a bunch of new functions, nothing fancy but you can actually zoom & pan now. You can also pause the game, and I added an in-game screenshot capability which is just perfect now that the game looks worse than ever. Pausing the game, which seems like a pretty simple thing, is actually a pain in the ass for a game like this, so that was it's own sub-sidequest, but it needed to be done sooner than later, anyway.

As far as the sensors go, I'm waiting until I reintroduce space stations & docking before I really flesh things out, but the base architecture is in place. The biggest change from the old system is that sensor pings are now modeled as radio waves propagating at light speed, rather than being magically instantaneous. This will introduce some weirdness once I reimplement the warp drive; I haven't quite decided how I'm going to deal with that, but the warp bubble will probably just block outgoing radio waves, which might make for an interesting mechanic.

Coming Up Next

As I said up top, I'm still working on close range physics, AKA running into shit. I've got a busy couple of months coming up, so development will be taking a bit of a backseat. My only plan is to keep plunking away at physics range & collisions until I'm happy with it.

Main Boosters & Attitude Stabilizers

Steady progress this month as I continue rebuilding the main flight systems. Things are going a bit slower than I'd originally intended, but as I mentioned last month, the goals have shifted. I'm not worried so much about 'catching back up' to where I was before. Instead, I'm focusing on building robust systems that work, more or less, the way I imagine the final version to work, right off the bat.

I'm also just being smarter in the way I structure the code, taking refactoring detours as needed. Whenever I find myself about to write a comment like "Dear future me," I ask myself if I'd be better off taking a little sidequest rather than adding another point to the future todo list. So far, future me has appreciated the effort.

Booster System

Wooosh

The boosters work basically the same way as before, but there are some important changes. First, just like with the RCS thrusters, the port & starboard boosters are modeled independently, and accumulate damage asymmetrically, requiring occasional adjustments & repairs. They're also upgradable, with a few different booster options already added to the game.

As before, there are 3 boost modes: reverse, normal (formerly 'maneuvering'), and overdrive (formerly 'boost'). Once I get around to putting the cockpit together, there will be a shift lever to change modes, rather than console buttons, because that feels more badass space trucky to me. Boost is now separate from RCS, so you'll still have access to RCS regardless of boost mode. There's no longer a docking mode. Instead, you'll have more control over RCS power to facilitate high precision docking maneuvers.

Unlike the previous 'boost mode', overdrive is intended for emergency situations only. It provides a lot of extra thrust, but burns through fuel prohibitively quickly. Speaking of fuel, it actually has mass now, as does the fuel tank itself, which is also upgradable.

Finally, you'll no longer have to throttle down completely in order to change booster modes, but it will still be best practice to do so in order to avoid unnecessary damage to the boosters. There's now a 'throttle lock' toggle that will prevent accidentally shifting while throttled up, but whether or not you use it is up to you.

Attitude Stabilizers

I'm currently finishing up the new & improved attitude stabilizers, which I'm calling gyroscopic because it sounds cool, but they're modeled as reaction wheels. I say 'they' because rotational velocity is now considered on all 3 axes independently. Each axis has a wheel with a maximum 'saturation' velocity, above which they need to be desaturated manually by applying rotation in the opposite direction via RCS. This makes the system slightly less magical, and brings it more into line with it's intended gameplay use, which is just to bleed off that last little bit of angular velocity as you steady the ship. It also means that I can give the stabilizers meaningful stats and add them to the repair/replace/upgrade system along with the boosters & RCS thrusters.

I'm still working on these, so I'll have a little more to say about them next month. But, like, they're cooler than before is what I'm trying to say here.

Coming Up Next

Once work on the stabilizers is complete I need to spend some time modeling the internals of the fuel system. That shouldn't take too long, I don't think, so I'll finally be able to move on to system scale & close range physics, I MEAN IT THIS TIME PROBABLY!

Kicking off v1 REDUX

Despite a slow start this month due to a nice long camping trip, a busy-as-always start to beekeeping season, and a weekend lost to getting drunk and watching Tetris (CTWC 2025!), I'm pretty stoked about how much I'm getting done. A more robust Newtonian motion implementation is neatly in place, ship flight controls are being rebuilt from the ground up, and new gameplay elements are already starting to stack up. I'm building a MUCH more robust codebase and generally feeling good!

Evolving Development Strategy

Last time, my general strat was to implement the minimum viable placeholder version of a feature or system with the plan to basically replace it later. This made sense at the time; I had never used Unity, didn't know exactly what I wanted Black Road Sky to be, and had never worked on a large programming project by myself before. Why waste a bunch of time perfecting, for example, the RCS system, when I didn't even know if I'd be able to add planets, much less orbital mechanics, to the game?

This time it's different. While I still believe deeply in the philosophy of never really knowing what the fuck one is doing, I think that I never know what the fuck I'm doing in a much more refined way these days. Honing the fucking art. So even though I still plan on returning to the initial implementations with an eventual refinement pass, I'm striving for a much more robust baseline version, matching the final gameplay vision more closely.

New Shitty Ship Design

TRUST ME GUYS IT'S CALLED PROGRESS

On the one hand, yeah, this looks like a bit of a step backwards, but on the other, you know, the ship never looked that good. This design is purely utilitarian, and will remain so until I have all the moving parts in place. I worried too much about aesthetics before, with little to show for it, so I'm letting graphics take even more of a backseat this time around. Now that I actually know a little bit about modeling, materials, lighting and all that, I'm more comfortable just waiting to deal with the visual style later, while letting things progress naturally in the meantime with a focus on simulation & core gameplay.

I backed myself into some corners with the previous design, so now I'm lasering in on function with the plan to eventually design around it. The model looks shitty, but it includes a fore utility dock for external docking in addition to the aft cargo dock, a portside airlock to accommodate EVA gameplay, warp rings, main boosters, room for deployable radiators and comms hardware, and functional (rather than cosmetic) RCS thrusters, which I have a lot of say about!

Saying a Lot About RCS Thrusters

The RCS system has been completely overhauled, and is already in a state pretty close to the final vision. Before, I was simply looking for player input and applying an according rotation to the entire ship- adding torque to the rigidbody, in Unity terms. Now, each of the 4 RCS thrusters are modeled independently with their own base stats and health, and force is actually applied from the thruster positions. This means that ship mass and center of mass now matter, which will be important once we start hauling cargo. It also means that thrusters can incur individual collision & wear damage, affecting their function asymmetrically.

Obviously this has a huge impact on how the ship flies over time. Pilots can compensate by tweaking the settings of internal hardware (fuel pumps & manifold, which currently exist only virtually since I haven't reimplemented the 1st person scale yet), and by paying for periodic repairs or upgrades. I'll add that functionality once I reintroduce space stations, but the bones of the upgrade system is already in place. I can easily create new thruster types and swap between them. Different thruster models have their own min & max thrust powers, responsiveness (time taken to ramp up & down after player input), durability, and so on. I even invented multiple in-universe manufacturing companies to make the parts, because it just wouldn't be Potato Clock Games if I remained focused for too long.

All of this supports the kind of gameplay I'd always imagined for Black Road Sky: a meaningful damage/repair system, upgradable hardware components, optional pre-flight checks and in-flight tweaks, and an overall more refined space trucking experience.

Coming Up Next

The main boosters and gyroscopic attitude stabilizers are now getting similar treatments to the RCS system, so far so good.

Then I'll move on to overhauling the game's close-range physics (ship-space station interactions, basically) and getting that playing nicely with solar system-scale interactions. Easier said than done, but these are problems that I've already more or less solved in the previous version.

Hopefully I don't get any farther than that, because then I'll have to deal with orbital mechanics, which I'm kind of dreading, even though it was MOSTLY solved in the previous version. Anyway, that's a future-me problem! For now, it's back to work on flight controls.

The Next Stitch - Repeating the Mantra

One stitch. Tiny stitch. When you think how many yards you will sew, chanting the Buddha’s name with every stitch, if you count all the stitches, you say, ‘I cannot do it!’ But, if you do this stitch: one stitch. One stitch. One stitch continuously, you will finish. If you stop, if you quit, even if you are very good at stitching, you will never finish. Just continue! When you continue with the stitching you will have many problems. Experience. Yes. That is your life.

"Aw, Here it Goes!"

Alright, ya'll, it's fucking happening! I'm starting over. This might sound dramatic, but I'm pretty sure it's the right call, and it's not unprecedented. This will be the 3rd time that I've started over with Black Road Sky; each time I've learned a ton of important skills & lessons, and each time the game has turned out better as a result.

I'll be sticking with Unity, which means that I'll be able to reuse a lot of code, and I'm starting off more or less knowing what the fuck I'm doing. I know what problems are going to arise in the future, and I can prepare for them. I know what features to concentrate on, and what to save for later. I think I can catch back up relatively quickly, with a much stronger code base and a better game all around.

I spent some time this past month in planning & getting organized, but I'm just now getting back to work in earnest. I needed that break, and mostly spent it playing other people's blue collar space games (Hardspace: Shipbreaker and Star Trucker, both recommended) instead of making my own.

Coming Up Next

I'm truly starting over, and first thing on the agenda is to rebuild the Newtonian motion simulation. Even at this most basic level, I have some ideas for improvements. Then it's on to revisiting the orbital mechanics, system/first-person scale interactions, all that. I don't want to say too much, because maybe I'll just run out of steam, but I'm feeling pretty inspired at the moment. Next few months should be interesting!

v1 REDUX

I'm Starting Over

 That is all.

BRS Development on Hiatus

Well, fuck.

Putting Shit On Pause

I haven't worked on Black Road Sky at all for the past few weeks. I ran into way more bugs than expected, and will probably have to roll back some of the new features as a result. Which is a bummer, because this was already going to be a pretty lackluster update. It just got to a point where I dreaded getting out of bed in the morning, knowing that I would have to work on this game. Dumb, I know.

Black Road Sky isn't the problem, really, but it's one of the few time sinks & sources of stress in my life that I can choose to just, like, not do. I've been feeling generally overwhelmed and I can't just quit going to work (or can I?) and I can't just quit being dragged along in an unrelenting social, economic and political nightmare (or can I?) and I can't just quit perceiving reality as a bewildered speck of consciousness awash in a staggering deluge of universal suffering (OR CAN I?) but ... I can definitely just quit making my little video game for a while.

I feel shitty stepping back so close to version release, and I feel especially shitty for having suggested that it would be finished before this year. And I feel extra especially shitty because this was just supposed to be a little catchup release before moving on to ship systems, which I am still, even in my current state of minor existential distress, really, really looking forward to working on. But I've moved past the stage of beating myself up over it and am pretty comfortably into the ah, fuck it, this is just the way it is stage.

The Future of Black Road Sky

I have every intention of getting back to work in the not-too-distant future. I'm feeling a lot like I did around the start of 2022, and I've been considering the same 'give up' / 'start over' / 'muscle through it' options that I did back then. I've decided that it's definitely not time to give up, and although starting over does sound hella refreshing, I'll probably just keep muscling through. That's kinda my jam. Just need to gulp down a few lungfuls of air before diving back into the thriving madhouse of bugs that I've managed to foster.

Hopefully the world doesn't end between now & then, but if it does, you know, that's one less thing.

Coming Up Next

I won't pretend to know. But today is the first warm, sunny day we've had in months. I think I'll go for a walk.
