has anyone considered to write a game engine in kt native?

I’ve made something with SDL2, but I didn’t went too far because of time constraints

I see, maybe it will be more worth it when it gets out of

0.*

I mean, it works, but it’s not even near something you can call a “game engine” 🙂 Just some SDL2 wrappers, a little bit of game loop, event processing and some very rough drafts on UI, scenes, and other composition ideas.

have you maybe got some performance metrics?

I did some game engines in cpp and it's so tedious to code in that language... I hope someday kotlin becomes a good alternative for engines' native code!

@elect other than it works at 60fps with vsync for simple hex grid rendering, no. I added something like dropwizard metrics to gauge various phases of game loop, but didn’t spend a lot of time on that. Also it was like several months ago and K/N got a lot of perf optimizations since then.

IMO, the best usecase of Kotlin, including K/N in gaming is not developing an engine from scratch (especially modern 3D one), but using it as a scripting engine for existing engine

I don’t think we are talking professional game engine here :) there is always a place for fun in life, why can’t it be K/N game engine?

why wouldn't a modern 3d engine be a good use case? nowadays most computations are done in the gpu anyways

Because it’s a lot of work, I suppose. And requires specific expertise. If you have time & knowledge – you’re welcome! 😄

I may do something opensource using jvm and lwjgl3, and once native tooling improves it should be pretty straight forward to move to native, shouldnt it?

what do you have in mind, @Pere Casafont?

I have a small game engine with networking written in java for hobby, but it got polluted with game specific code and I'm not in the games industry anymore so maybe I will opensource it

cool
