LAUNCH.WAD

So I've been researching the Doom movement code and made something to try and exploit the rare "elastic collision" bug I've been documenting.

Interesting.

Ive always noticed something nutty in maps with corners with very low angles, such as curved hallways or mountains. I remember a map in Swim With The Whales that drove me crazy because I had to dodge fireballs while backpedalling into a narrow trench for cover that kept spitting me out. Sliding along the walls in the curved tunnels of MAP03: Aztec in Plutonia are a good example.

Interesting, Ling. I understand what's happening here but not why it's happening. I've bounced around maps more than a few times, but I've never seen a bounce that is so drastically and consistently fast, though of course being in-air keeps the momentum the same.

I notice that this seems to be easier to achieve in PrBoom+ than in chocolate (at least while playing through D-Touch). Though I feel like even on the PC I bounce around a lot more in PrBoom+ than I used to playing in vanilla as a kid; granted that could be due to the extra detailing in pWads not present in the iWads.
