Someone should take away my ability to write template code in C++
Although given how much effort this took to write, perhaps they already did

Slightly late #ScreenshotSaturday of my tricky burger building game
Lunch Rush is out, it tickles that retro puzzle itch, and you can play in your browser for free here sireel.itch.io/lunch-rush

What's fun is the original function (pictured) is domain clamped. It can't come out wrong, the sinf should produce things in [0,1].
It turns out sinf(M_PI) is a small negative number. I'm not sure if that's because SDL's pi is poorly chosen, or any of a dozen other reasons - it doesn't matter

{
t = clamp(0, 1, t);
return sinf(t * M_PI) * config.tileHeight * 0.3f;
};

My next game is finally shippable, but I'm staring at the draft of the itch page thinking something's missing.
It doesn't help that I know the core of the game is fundamentally tricky in a way which will put most people off giving it more than a cursory try.
↓ Anyone want to playtest this? ↓

Game devs post your first shipped game and your latest shipped game.
I don't care that the latest wasn't a commercial release, I'm proud of it. Play in your browser here for free: sireel.itch.io/breakfast-game

After weeks of procrastination, I finally finished the title logo for my new game.
No I will not make it good later. Making it exist was more than enough for me.

I fixed a stupid bug and wrote a little thread about tracking it down.
I also realised that I've not posted a single video of the new game's gameplay so I thought I'd fix that this #ScreenshotSaturday

Of course. An uninitialised screen pointer. Something that should have failed 99% of the time somehow worked 95%+ of the time. It must have been initialised to zero most of the time, as a junk value should segfault in the native build.
Despite testing it in release mode, it never once hit

I'm building with emscripten, so it's literally as easy as adding the standard gcc debug flag -g. This told me my crash location was... my render function?
Specifically binding the back buffer I use for making a fixed screen resolution. But the code looks fine. Best to check carefully though

The callstack in the web build was not helpful. And I knew from experience even if I had a stack, it might not answer the problem without debugging.
At this point I hadn't realised it was first run only, so I wrote a quick and dirty input fuzzer to run in the compiled version

Showed my eight year old Fusion 2 as an easy on ramp to game dev
He's abandoned three projects already, I couldn't be more proud

Another day messing with UI. Grabbed a free background from itch (took a while to find one that wasn't generated).
Jiggled the layout a little too for the frames, but I think it's an improvement!

Seeing this again I'm compelled to remind people that for 80% of it (and 100% of me) the vitamin is sleep, and quite possibly some actual vitamins.
Failing that, we might all just need some means of production, which I hear can be seized from somewhere around here

My next game is in a playable if rough state. I'm hoping I can find some decent puzzle game players to test it before I'm ready to release as its very hard to gauge difficulty!

Spotted a Red Admiral at the play park. Looking a little worse for wear though 😭

Got even luckier after a couple more!

I saw 23-28 butterflies on a ten minute walk through a nearby park. Shortly after I stopped counting I saw a group of seven together, and another five not long after that.
It seems like there's a lot more than I remember last year!
