Scattershot update

Quite a few things to put out there today.

Mac and Linux progress

This has been my main focus recently, and though I’m aware that this part of the project is well overdue (more on that in the ‘lessons learned’ section later on), we’re down to the last handful of bugs before the alpha releases on MacOS. Rob reports that he’s been having more trouble than expected with various parts of the project – it was a bit of an unknown working with C# and MacOS in the first place, but there have been more unknown unknowns than either of us saw coming. At this point it’s essentially all UI fixes, but unfortunately they’re not the kind of thing that can be handwaved, even for an alpha. It’s been frustrating at our end, since Halley is a Mac user and has been keen on getting this version sorted for a long time, but the end is very much in sight. I apologise for how long this is taking, though – I don’t mean to gloss over the fact that it’s much longer than expected.

As for Linux, because the MacOS version is mostly in Rob’s hands now, I’ve been looking at the Linux build. This isn’t as big a deal as the Mac version (in terms of work, I mean) because it doesn’t involve an entire UI rewrite, but there are lots of problems that have previously been in the too-hard basket because previous releases haven’t been in any way final, which I’m now having to face head on. A big part of all this is packaging and general unfamiliarity with deployment conventions at this point.

A few engine things

Unreal 4

This is an odd one. Lots of people have been asking me about integration between Sprite Lamp and Unreal 4. I feel a little bit like the winds of change are blowing in the indie gaming word – it seems like everywhere I turn, people are talking about their new project using Unreal 4, or the various advantages the engine offers. I don’t know whether Unreal 4 is going to replace Unity in the near future, but it was enough to convince me that it’d be irresponsible to not look into Sprite Lamp and Unreal 4 playing together.

I’ve spent some time recently learning the engine a bit, and… well, beyond normal maps, it’s not clear there’s much I can do with Unreal 4. As usual, it’s a modern engine and can therefore handle dynamic lighting and normal maps just fine. However, because it uses deferred rendering in a very fundamental way, it’s no longer possible to just write your own custom lighting model with Unreal 4 as far as I can see (and the fancier features of Sprite Lamp’s shaders fall into that category). I’ll add two caveats to that – first is, obviously people are capable of achieving amazing things with Unreal 4’s lighting, and that includes nonphotorealistic results, so very likely things like cel shading are still possible. It just means that I won’t be writing the exact shader from the preview window of Sprite Lamp into Unreal 4, because that appears to not be possible. The other thing is that since Unreal 4 has its full source code available, technically it’s not really true to say that anything can’t be done – almost anything is possible. However, I think that trying to maintain a source-modified version of the engine (that would survive integration when Epic updates and so on) is probably more trouble than it’s worth for everyone involved.


Another engine that seems to be picking up steam a bit is Godot. Since it’s completely free and open source, Godot’s appeal isn’t hard to understand. I don’t know a great deal about it yet, but I’ve been following along and it seems that 2D lighting is a priority for them in the near future, which is obviously very relevant to my interests, and perhaps yours. That said, unlike Unreal, I haven’t particularly gotten the impression that lots of people using Godot are also using Sprite Lamp – if you’re a Godot fan and would like me to look closer at its use with Sprite Lamp, let me know.

Real life issues

As you’re probably aware, Sprite Lamp has been out on Steam and Humble for a couple of months now, and though it’s doing okay for itself, taken in combination with the above issues about the Mac port taking way longer than expected, it would be financially risky for me to just assume that I can live indefinitely on Sprite Lamp. This has necessitating me getting myself a ‘real job’. It’s a job that doesn’t consume all my time, and don’t plan on completely returning to the normal full time employment world for a little while yet (not while Sprite Lamp is ongoing, certainly).

Lessons learned

One day, I’ll do a proper Sprite Lamp post-mortem, but there are two important things I’d like to put out there in case anyone might learn from them.

First off, it’s clear to me now that the biggest technical misjudgement on my part for this project was underestimating the difficulty of working with unfamiliar platforms. I’ve only ever been a Windows developer, so (I thought) I had a suitably healthy fear for working with other platforms – that’s why I went and made proof-of-concept stuff for MacOS and Linux before promising those versions on the Kickstarter campaign. Still, I was unprepared for how much work gets bogged down (for me, at least) by not knowing the operating system. As a simple example, I recently spent an embarrassingly long time tracking down some issue with apt-get on my Linux install that was stopping me from progressing, which ultimately culminated in having to install a newer version of Linux (which, to its credit, went very smoothly). That stuff adds up, and it’s not psychologically great when it feels like you spend as much time fighting with problems of unfamiliarity as you do writing code. I’m hoping future projects of mine can be cross platform, but I’m definitely going to be less gung-ho in my assumptions. Certainly I cringe internally to recall my intention to do a simultaneous cross-platform release.

Second off, and a little personally, I didn’t foresee how much being a (very very mildly) public figure would be a source of stress, and how crap I would be at maintaining stuff like this blog, a social media presence, etc. I’m actually not a terribly shy person in real life (although admittedly with game development to some extent you’re grading against a curve there), but apparently I am in the internet world, which seems to be the reverse of how most people feel. This mostly makes me respect community managers a lot more, but also gives me some reason to pause in the goal of being an indie developer, since it kind of comes with the territory. Not sure how I’ll feel about that going forward, but if anyone has actually read this far and has any advice on the same kind of thing, please let me know.


Anyway, that’s it for now, and I’m back to figuring out Linuxy things. To anyone who read this far, I hope you celebrated whatever they’re inclined to to the best of their ability, and that 2015 is as good or better than 2014.
