Heres a few, kinda useful for tetris type games and map generating new array function newAr(h,w) local ar = {} for i=1,h do ar[i] = {} for j=1,w do ar[i][j] = 0 end end return ar end transpose array function transpose(ar) local ar2 = newAr(#ar,#ar[1]) for i=1,#ar do for j=1,#ar[i] do ar2[j][i] = ar[...

Just realized this thread was about actual code, not books
The lua source code is pretty nice if you're into C

either to sleep for longer periods of time or change to a fixed timestep. Well, the OS system call that love.timer.sleep uses is inherently inaccurate (on Windows in particular.)
