This is the only spell page so far. This is the real purpose of the book. The idea came from getting annoyed at how much info is missing from the dnd beyond spell list when you print your character sheet.
The goal is to include all important numbers and rules, and flavour info to make it feel real

I decided to put in class features the character has yet to unlock, to save me trying to work out and remember the layout to leave enough space.
It was a nice excuse to draw more diagrams

I'm planning for the book to act as most of a character sheet. The things that change too frequently to want to keep editing (e.g., proficiency bonus, hp, skills and proficiencies) I'm going to create a miniature character sheet for, and just insert it into the front

And finished. Learned a lesson about what to protect from glue, but I'm pretty happy with it!

This is the finished text block. I added some bookmark ribbons as in likely to want to bookmark multiple pages for quick reference.
I'm actually waiting for the final glue up to set for the whole thing, but I forgot to take a wip pic of the cover

Due to ongoing horrors (scroll up or down slightly for more info) I decided I needed another hobby.
So I'm making a spell book for my 5e Wizard in the campaign I play with my kid

I always feel like I suck at Zachtronics games, but I guess I did ok on this rice cooker level :D

QTP with your first Pokémon game and starter!
I got blue very early, because I found a US import copy. It was super cheap - £20 instead of the standard 30 (which the copy of red next to it was priced at!)
I'd long since finished the game before it really hit big here, which felt weird

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? ↓

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
