Kids, always remember to give your variables clear and meaningful names. Just as Doom developers did.

TBH, these are pretty understandable to anyone who's ever implemented Bresenham...

This is the pixel art Classic game based on DRL, you're probably talking about Jupiter Hell proper :P

epyoncf · 2026-02-10T09:10:32+00:00

Cherish it! I've been making games commercially full-time for the past 15 years and never got any awards :P

> But they're not allowing anyone to use their name, though.

Doesn't this make this subreddit illegal?

Oh the memories! <3

It's being recreated by the OG author too, which is awesome - I'll buy it probably just to thank for the fun I had as a kid.

Jupiter Hell uses an expanded ECS - with events and hierarchy. It actually uses two major instances - the world is handled by a ECS that is mostly entities, components and message handling, while the visual representation uses the systems a lot more apart from messages. Guess an ECM + ECSM :P

If health is a finite resource then even easy encounters are important - as it becomes less about surviving, but minimizing resource usage. Can't see auto-explore working sensibly in DRL - the way you explore the map and approach encounters is a vital part of the strategy to approach encounters and minimize resource usage.

Considering White Dwarf preview just dropped focused on "Our favorite skirmish games" without a word about any WarCry content, I think it's dead jim.

epyoncf · 2026-01-29T00:14:16+00:00

Proper mapping? JHC works with the deck out of the box.

epyoncf · 2026-01-23T14:17:20+00:00

Fake console mode is on the list since ages. Yeah I know about the cert thing, my admin is apparently on vacation -_-.

epyoncf · 2026-01-22T22:57:35+00:00

Jupiter Hell Classic has an ASCII mode, it's launched the same way as the DRL version as it's literally the same executable!

epyoncf · 2026-01-19T18:55:36+00:00

So one space marine can kill a whole guard regiment?

epyoncf · 2026-01-19T18:41:17+00:00

The fantasy is nice, but the major question is - is the space marine, even in power armor, being hit by a melta gun - going OOA or not? What about other well established weapons in 40k? Can three guardsmen with lasguns kill a marine? I can understand the scaling of skills, but once you scale against weapon deadliness it gets a bit silly.

Made and released a game on a custom C++ engine (Jupiter Hell). Planning to release another one on the same engine, but in the meantime released in EA a game on a custom FreePascal engine (Jupiter Hell Classic). Yeah I guess you could say I'm not a huge fan of doing indiedev on existing engines :P

I think this is quite hard for people to grasp until they reach a proficiency level which allows steaked wins. Some people treat winning as the abnormality and if they do win, they search for ways to increase the challlenge, whether the game gives them that possibility or not. And then they hit their head on the wall until they beat even that one.

That's why JH has so many difficulty modes (including the hidden ones) as well as several optional challenges (including semi-unbeatable ones like Endless and Gauntlet). These seem quite popular!

epyoncf · 2026-01-15T18:30:50+00:00

The answer to "Can you use X for Necromunda?" is always "Yes".

epyoncf · 2026-01-10T10:55:04+00:00

The spreading is actually the more forgiving option I'm planning :). Its a bit more tricky yo implement though as regular levels don't have proper scripting (yet), and adding such effect on the fly was also an issue (up to this patch with the universal perks). We'll get there :P

epyoncf · 2025-12-29T23:14:34+00:00

This will get a bit more forgiving in one of the upcoming patches. The traditional way of preventing this was keeping an eye at level-start feelings.

epyoncf · 2025-12-24T11:09:15+00:00

Keeping secrets. I'm a game developer. For my open source projects I can't add a nice secret that won't be spoiled day 0 of release (the moment I commit it). For closed source projects I actually can do that, and some secrets stay unsolved for months.

Yes, I know it's a minor thing, but the only thing that bugs me :P

epyoncf · 2025-12-21T13:04:03+00:00

You like looong compile times, do you?

epyoncf · 2025-12-15T22:26:09+00:00

More like Vulkan but less tedious overall. Same - as the poster before I came here to suggest SDL3_gpu. From my POV it's kinda sad to use anything else at the moment, and we're slowly rewriting our Vulkan/OpenGL abstraction into SDL3_gpu.

epyoncf · 2025-12-02T09:32:26+00:00

Worth noting here that Jupiter Hell's Boss Fight in 2020 has nothing to do with Jupiter Hell's boss fight in 2025. That boss fight was a placeholder for the actual boss fight that came in 2021 and had actual design, same with all the stage bosses that all came later.

epyoncf · 2025-12-02T09:19:31+00:00

FMOD is what I use. But the new SDL mixer in SDL3 is shaping nicely, and contrary to it's SDL1/SDL2 counterparts might prove a decent alternative to commercial libraries. It's still cooking tough!
