That's a good idea, Robin. Thanks. I ran with it in what's probably not the direction you had in mind, but what do you think of this? -- only downside: won't work with pairs() function makeDeltaTable(t) t = t or {} t.__delta = {} t.__index = function(t,k) return getmetatable(t)[k] end t.__newindex ...

technically, the copyright you have for all the resources you made yourself (code, art, music, whatever, assuming they aren't derivative works) is going to be far more powerful than any sort of protection you put in your code. of course this means you'd have to put in the effort to enforce these cop...

interesting. how much of svg are you planning to implement? months ago i considered writing a lib that would "compile" an svg document into a sequence of love.graphics functions... i thought svg tiny would be a good starting point until i realized the spec was over 400 pages lol

my `toboolean` function would simply be function toboolean(o) return not not o end lua already has specific semantics for objects being converted to boolean values, so peeking into the actual value to determine truthiness is dodgy [de]serialization is an exception of course, but i would choose a dif...

I need to paste imageData 1 onto another imageData 2, where imageData 1 has transparent parts. Using imageDate2:paste(...) it will replace the part of the image entirely. Instead, I want it to overlay the two (I want it to look the way it looks when using love.graphics.draw() over another love.grap...

One thing I do remember is that, under normal circumstances, lua will not shrink the memory that's already allocated to a table, so you need to make sure that those empty spaces never get allocated in the first place (as opposed to creating all of them, then running back through and setting them al...

Can't really think of a reason one would need this in a game environment anyway. maybe a puzzle game where you have to physically move windows to solve the puzzles (or some weird artsy platformer or something). somebody's probably done this by now i would imagine or even something boring like the a...

function calls are somewhat expensive (especially since the standard vm doesn't inline them), so if something can be done without a function call it will probably be cheaper to do it that way. pure-lua bitwise ops would be a pretty big exception to this, though. obviously this doesn't really apply i...

nope :>

you may want to try luajit again the final release is able to completely eliminate object allocations in some cases. temporary vectors are pretty amenable to this optimization if you're careful. you may not quite reach c++ performance but it should hopefully perform somewhat better at least. but you...
