Always a bit longer in JS than on the Commodore.
u/loktar

If not for having to scale to make it viewable it can actually be smaller, removing scale and doing 2e3, vs 750 produces a nice result fullscreen.

#maze wow, some amazing implementations I'm glad I didn't check prior lol.
u/andrea270872

I learned programming with a C64! Ah, the nostalgia :)
u/loktar

@andrea270872 same here actually, although I've accumulated many more Commodores and various models since then haha

Building an infinite maze.

I did not have space for Math.random, so i have used the decimals from t variable multiplying by 1e8 and then extract one variable bit for true/false condition. Thus it is not true random
u/aleamb

Better said, it is worst than Math.random
