Fly your Arwing to victory in this demake of a certain, iconic SNES game.

Controls:
Arrow Keys: Move ship, Select level in title screen
z/o: Fire

Features:
Filled 3D polygon graphics-- reminiscent of SuperFX chip
3 levels -- select with left or right on the title screen
2 enemy types
Music

Special thanks:
Star Fox Cornerea music sequenced by PJBarnes.com (http://www.khinsider.com/midi/snes/starfox) and imported using kittenm4ster's midi to pico-8 tracker translator (https://github.com/andmatand/midi-to-pico8)

Notes:
I finished this game with our three week old son sitting in my lap. I guess this is one our first father-son activities together--kinda sweet in a very nerdy way. Perhaps his first words will be in Lua.

Let me know if you would be interested in a cleaned up version of the 3D library that I put together for this project.

Well this is just nuts.

I think we'd all be interested in the engine you created for this. I was not a big Star Fox fan but I'm a fan of rail shooters, so I can see using this for any number of third-person shooter games.

Just amazing to me...I mean, I'm still figuring out how to use f'ing sin/cos effectively and here's this thing.

Liquidream • 2016-11-15*2016-11-15 00:46*

Wow. Just WOW! :D

NuSan • 2016-11-15*2016-11-15 01:23*

Realy great visual, I like the "horizontal lines" shading. Only odd part was the music not stopping/changing when you finish a level.

Hadrien • 2016-11-15*2016-11-15 05:02*

Wow, awesome demake! clap clap

salah • 2016-11-15*2016-11-15 11:57*

Good job.

qbicfeet • 2016-11-15*2016-11-15 15:02*

Holy shit, this is on point. I'm a fan of the shading as well, it fits really well with this style of graphics and doesn't become distracting.

Fantastic job! Very authentic.

Eduardolicious • 2016-11-15*2016-11-15 21:29*

this has completely blown my damn mind. just unbelievable

shadow1w2 • 2016-11-15*2016-11-15 22:14*

Runs rather smoothly nice.
If ya wanted more controls could combine the player two buttons for it but kinda hard to set that up practically without easy ways to bind them to an actual controller.

Hope to see some more games using this style and setup.

mooora • 2016-11-16*2016-11-16 09:16*

yes this is amazing, much more smooth than the original SNES :D
seriously, really impressive.

minsoft • 2016-11-16*2016-11-16 10:04*

Wow, incredible! Hats off to you.

computermouth • 2016-11-16*2016-11-16 15:54*

I would love to get at that cleaned up 3D code!

electricgryphon • 2016-11-17*2016-11-17 02:00*

I just posted a 3D library for folks to use: https://www.lexaloffle.com/bbs/?tid=28077

johnesco • 2016-12-16*2016-12-16 03:06*

Does anyone else mutter "Good Luck!" to themselves in a mechanical voice when starting each level?

anthonysavatar • 2017-01-02*2017-01-02 15:00*

Love the game and the 3d library! I noticed the token count is pretty high for this game due to the arrays of numbers. If you pack the numbers into strings and load them at runtime it can save you a bunch of tokens. I gave it a go on PicoFox and got the token count down from 8177 to 6821.
The compressed size went down a bit too from 13745 to 13533. That might give you some breathing space for more game features :-)

Here is the function and all the vertices replaced with strings. Numbers are separated by spaces and each string must end in a space. I also removed any tab characters.

-- split number string into an array
function s(str)
 local t={}
 local t_index=1
 local start_index=1
 for i=1,#str do
  if sub(str,i,i)==" " then
   t[t_index]=sub(str,start_index,i-1)+0
   t_index+=1
   start_index=i+1
  end
 end
 return t
end
