RNGs, demos and technical nonsense

3 years ago

Hey!

I've recently made a lot of process in terms of rendering/drawing algorithms and I'm slowly starting to implement things/actors (sprites) in to my crummy DOOM port (see https://gamejolt.com/p/knee-deep-in-carmack-s-spaghetti-tqktxc2v)
I've been thinking about what kind of an RNG (random number generator) system I should add to the game.
Should I...

[A] just copy the 255 byte RNG table from DOOM (demo compatible)

[B] make my own pseudo-random number generator (demo compatible)

[C] use the RNG provided by Scratch (not compatible with demos)

Demos in this case refer to "replays" of the player inputs, that could be shared around

If/when I get the game mostly working I'll probably share a video or two to the D7, Scratch and TurboWarp communities.

-sincerely, that one guy who keeps shoving DOOM into Scratch, Juvepa

[A] DOOM "RNG"

[B] DIY PRNG

[C] Scratch RNG

You know how PS1/N64 DOOM had fancy coloured lights? Thanks to some clever pen tricks, it's in WolfenDoom 2.5D* as well! (I also added pickups, hitscanners and a crappy fisheye remover)

*title may change

Reject sprite 3D, embrace pen. I only need to add a proper texture interpreter (instead of manually adding patches), and it's a decent port of Doom!
