I know I am in the minority and my uses/needs/requirements are not average, but I am perfectly fine with running Xubuntu on the following hardware: 1) 4GB 2011 Thinkpad with HDD (yeah really) and 2) 4GB 2009 Phenom desktop (was Wi

I found out about profiles recently and I just couldn't believe that that's the standard way to access them. Also, it's not obvious which profile you are currently on, so there are some silly but necessary workarounds like ha

If you keep resolution low, manage your scene complexity carefully and commit to the art style, you can make reasonable 3D games that run even on 20 year old hardware. I did so as an experiment on my game [1] [2] and now that I can see that

It would be cool indeed, I played around with !include_str and co. and works as expected. It wouldn't be possible for the user to modify the assets though, and to save the settings file.

Understandable. That's kind of the goal, the gameplay is very shallow complexity-wise, so raw responses/difficulty is one way to put some playing time into it. There are some methods that help a lot, like keeping a completely pe

Nice discussions! I've seen many of these projects lately around related communities. Happy to see a trend around this, as I really think there is actual merit in the topic. My project was more of a random timesink than something that

Interesting, I will look more into this. To be honest, grepping the source, I found a couple of places with for x in &myvec. Probably tried them while learning the language, they worked and left them there. But really, I am just more us

Thanks for trying it out. It's a regular inverse square law, no tricks. The numbers (masses, distance) determine the final acceleration but not the actual trend of the curve. I've become too familiar with it over testing to notice

Actually yes! I use it when passing a texture into a draw function. I have a TexOrColor enum, and when calling the function you either provide an &Image or a &Color. Before that, if I wanted a colored textureless model, I passed a d

You mean implicitly? I am aware that idiomatic Rust strongly prefers iterators over indices for performance, but in my case, the only place where it really matters is when counting pixels to draw, and there is no kind of collection there, j

I'll see if I can produce a reasonably readable stripped down version (the lib + an example scene) and I might be back soon ;)

Right, it's a spectrum, you can't avoid some things (and rightly so). Another soft rule: no member functions (except for the Scenes); structs are only data, all functions are free functions. Also no operator overloading, so yes, l

It's all single threaded. Just structs being passed around. For example, the mesh drawing call is: drawmeshindexed(m: &Mesh, mat: &Mat4x4, tex: &Image, uv_off: &TexCoord, li: &LightingInfo, cam: &Camera, buf: &a

It's a very procedural style. I have not used: iterators, lifetimes, Arcs/Boxes/RefCells and whatnot, any kind of generics, data structures other than vecs/arrays, async, and many more. Also avoided functional style, bui

Yeah it should be just a simple cargo build. But for the same reason it should be playable through any emulator/translation/VM layer as you mentioned.

Didn't know this, but I'd rather not use github to be honest. Isn't there also some kind of signing required to publish a Mac build?

by mvx64 1y ago
The game-side code, not really (I am ashamed of reading it myself). The engine-side is a bit less shameful, but I'd rather not as I mentioned elsewhere, especially on github. I may change my mind though.

I have considered getting a Mac in the past (even a very old Air) to make and, most importantly test, Mac builds, but I never got to it and cross-compiling to Mac seems like a pain, if at all possible. If you have a VM laying around though,

Thanks! For several reasons, most probably and regrettably no, for now at least. More than happy to talk about any specific part however (e.g. how scenes are handled, the code itself, or how particular features are implemented or optimized)
