A question about UV-Speed(Level 24 - Quarry) in Final Doom TNT - Evilution

[evocalvin]

hello i am a Doomer from Hong Kong

does anyone know what trick he used in this demo?
this is a COMPET-N demo - ev24-012.zip
Why he could be done suddenly?

thanks!! :)

That area (the lift and the room above) uses the damaging sector exit; the one used at the end of DOOM's 1st episode.

Yes, and to reach that area Adam uses a common speedrunning trick: running past a linedef which usually triggers something -- in this case, teleporting the player -- without triggering it.

thanks myk and Kristian Ronge
i understand now
but so far, i haven't done the level with the trick
it's very difficult to me

[Kristian Ronge]

That's speedrunning... If at first you don't succeed, die die again.

I know I am joining this discussion a little late, but in case you are struggling to find a way even to attempt this trick, then note that your chances of skipping a linedef are better if you are moving faster. Thus straferunning gives you a better chance, and strafe-50 even better. Other possible ways are to get a speed boost from a monster attack or from a thing-glide, wallrunning, etc. Though these obviously are location-dependent. A "wobble" against a thing or a vertex also seems to confuse the engine about your precise location, and also seems to increase the chance of crossing a lindef without triggering it.

I vaguely recall from reading textfiles from demos featuring this particular trick that it is a rather difficult and luck-laded one. So try to cross it at the highest speed you can, and pray from some good old-fashioned random luck.

Thanks Grazza for detailed response! : )
