Yes, that's all you can do in the last uploaded version (plus zoom in/out with I/O and look at some debug stuff with L). I didn't manage to get real gameplay in there by the end of the demo day- I hope to have something more polished the next time we do something like this.
Thanks for giving it a download and play! And thanks for the heads-up on the memory leak- turns out I didn't understand how you're meant to use openGL fence syncs. I thought you called glFenceSync every frame to synchronize stuff, but that actually creates a new fence object. Whoops! It's fixed now, and the memory leak is gone. Thank you!
I'm sorry about that! The laptop's power shouldn't be a problem so long as it's from the last 10 years and has OpenGL on it-I dev/test the game on a 2011 thinkpad. It's probably a problem with how I set it up for windows (although of course it ran fine on the win11 machine I tested it on...)
I'll need to setup win10 on a testing machine. Sorry it didn't work for you, that's really frustrating.
(If you're up for it, you could run the game's exe from console- it'll probably put out some kind error message when it crashes.)
They are! Not yet, it's a tech demo at present, though I hope to have a build with some gameplay out by the end of the Demo Day.
It's written in Jai, Jon Blow's new language. The engine is homebrew, but uses some libraries - Jai comes bundled with a bunch of modules, including one that I'm using for cross-platform window creation and setting up openGL contexts, text rendering, drawing primitives/sprites, etc. The language's modules are very hackable, which is nice.
There's a lot of raw OpenGL in the code, especially for the fluid dynamics simulation and rendering, which is done by having two textures for the fluid sim state (one 'now' and one which is for the next time step), and having the fluid sim shader read from the first and render to the second texture before the texture handles get swapped.
Please note: This is a tech demo, and doesn't have gameplay yet! At the moment, all you can do is make a goblin walk around in the little environment and watch the fluid sim run.
Quick update: now the fluid sim is rendered in the world, so I've disabled the sidebar debug render by default.
Controls:
WASD to move camera
right click+drag: rotate/zoom camera
left click: tell your goblin to walk here
I/O: zoom in/out
L: show/hide debug info
