LövePotion - LÖVE on 3DS Homebrew

[VideahGams]

Hey, the project isn't dead as such but I've had 0 time to work on it.
I've given TurtleP repo privileges because he has a lot more time on his hands and is a lot more motivated to make changes,
so you should see some development happening right about now.

Thank you. We are looking forward to it ))

Could you post some gfx/RAM restrictions of the port? Thank you.

Is it possible that "os.time" and "love.timer.getTime()" are not implemented yet ? trying to use one of this for "love.math.setRandomSeed( seed )", but on the 3ds i always get an "nill error".
Can anyone help ? or are there other ways to get a better random functionallity ?

love.timer.getTime seems to be implemented. https://github.com/VideahGams/LovePotio ... imer.c#L41

I posted a PRNG here a while back: viewtopic.php?f=5&t=80676

Will need bitwise ops shimmed with arithmetic equivalents if you don't have LuaJIT, not sure what that will do to performance but try it out

Cool, Thanks, will definitely try this out.

No problem, let me know how it goes. Shimming bit.rshift is straightforward, but you might need to compute a lookup table to get reasonable performance out of bit.bor. Might be better to implement bitwise stuff in LovePotion, in C (or compile against 5.2 or 5.3 if possible).

By the way, when I wrote that topic, Alea was faster than love.math.random, but it's not anymore. Still, love.math.random is less than twice as fast as Alea (it must have gotten faster at some point).

That's all with the JIT on. Good news is, with JIT turned off, Alea is about 3 times faster than love.math.random. This is still using LuaJIT's bit ops, though; you'll still need a good replacement for those.

Interesting (but irrelevant) side note, love.math.randomNormal doesn't appear to benefit from JIT at all. This makes love.math.randomNormal about twice as fast as love.math.random with JIT off, but with JIT on, it's something like 25x slower.
