It is really fun to see games coded in a language you know (and is not used for gamedev) -- completely new way of programming/thinking.

There is another great video similar to this of Tom Dalling coding a flappy bird clone using Gosu:

looks awesome, thanks for the link!

That is how C and Pascal got to displace Assembly, and C++ eventually displaced C in game development.

By having devs that instead of following "it cannot be done", persisted and eventually were able to release something in those languages that others wanted to play.

Having watched this cycle a few times, I always look forward to see higher level programming languages used in broader contexts.

However for game development, maybe Crystal instead of Ruby would still be a better option, in terms of raw performance and distribution.

considering rubymotion, i think ruby is still a feasible option though

Hey Nikolay, now write it in Bash!

ekianjo• 11 years ago

Bash would be really painful :)

Fantastic tutorial, I really like his presentation style of progressively walking through the commits. Great work.

angeloxlr8• 11 years ago

this is very awesome, big fan of the presentation technique

Works here (tm).

Releated links which may work for you if the article link is still dead:

Very cool Nikolay. I also dig the git-wayback machine briefly showcased.

thanks for the find, tried it found a bug and fixed it too :)

MadRabbit6• 11 years ago

hey Senthil, thanks for the fix! just rolled out a new version to rubygems :)

Cool stuff! Coding attack sequences, combos and reading commands like quarter-circles is a fun exercise, too. You have to balance between precision and ease of use.

Interesting strategies arise when this glitches:

Very cool and readable.

For something even cooler (but less readable) here is SF alpha, in js: https://github.com/gamedev8/js-sfa (very faithful to the SF alpha game mechanics)

MadRabbit6• 11 years ago

yeah i saw that one. it's alright. i'd do the sprites mapping in css with `clip` though :)

mikeskim• 11 years ago

this game feels nothing like street fighter alpha to anyone who has played sf competitively. it might look like it though.

I used to be a die hard fan of this game in my early teenage days and now Ruby is my most favorite. It would be a lot of fun building this game and connecting to some of my old memories. Thanks Nikolay.

MadRabbit6• 11 years ago

hey, no problem. send me a pull request! ;)

Rainymood• 11 years ago

Awesome! Please finish this up I have always been so intrigued on game design, especially fighting games.

lanebrain• 11 years ago

Very cool! Well done Nikolay. Cheers!

minhtran• 11 years ago

Do you have plan to add the code when 2 players hit each other?

MadRabbit6• 11 years ago

when i have time for it, yes. that would be my next sprint on the project

omouse• 11 years ago

I was just gonna say; the starting portion is to get something displayed, next step is collision detection and the victory conditions.

axx• 11 years ago

Very cool, thanks for sharing! :)

mc_hammer• 11 years ago

good watch

i liked the explanation of reducing draw() to 1 sprite per call and the little formula that went along with it; ive never seen that. make a video about just tricks used in the industry!

agentultra• 11 years ago

Very cool!

It's actually stunningly common to use high-level languages with managed run-times in games these days. Most indie and small-studio games we play today were built using one engine or another. The graphics pipeline in Unity, Gamemaker, etc might be heavily optimized but the majority of the game is written in an interpreted or managed language run-time like Lua or C#.

You can write 3D simulations with a decent frame-rate in Python. You just need a lot of help with the "hot" spots be calling out to C and C++ libraries for support. I've been experimenting with writing little 3D engines in Cython + Python + SDL2. It does end up taking a load more memory and performance can drop drastically if you're not consciously thinking about your data-flow. The trick I've found is to avoid most of the features that make Python great in those critical sections... plain old data structures, weak references, pack your data together and transform it once (ie: avoid copies).

However it's great for prototyping and toying with new ideas. Python is vastly more forgiving when you don't know up-front how you're going to structure your data flows.

But in the end I just end up going back to C99 at some point anyway.

Writing games in Ruby shouldn't be weird. It's cool.
