New switch press trick discovered for doom!
1,074Some time back I discovered it was possible to activate a switch from more than 64 units away, which everyone assumed was the max distance. It started on map 15 of doom 2 with a shortcut to the blue key as can be seen in the video.
Then 4shockblast discovered it's possible to activate the exit switch on map 04 of plutonia, but that requires a distance much larger than 64 units. This is the second video.
Then the snowball starting rolling, and map 07 of doom 2 was discovered to be possible to activate by looper. This is the 3rd video which is done in about 2-3 seconds using TAS.
Then looper discovered another thing, pressing a switch through the wall! on map 17 of doom 2. This is the last video where it is shown by JCD.
It should also be possible to complete map 32 of doom 2 without monsters by activating the switch through the wall (nomonsters removes the keen dolls so it was thought to be impossible). E4M2 secret exit should be much easier to reach and can be done pacifist without telefragging the cyberdemon.
Who knows what other levels might be improved from this.
To answer some FAQ:
Yes, this is obviously possible in dos\vanilla, and no, this is not just the normal infinite height switch trick.
Levels where this has been shown to be useful for the offical doom games Ultimate Doom, Doom II and Final doom are:
Ultimate Doom: E4M2 - Activating the secret exit through the wall.
Doom II: Map 07 - Activating exit switch.
Map 15 - Activating switch to open door to blue key.
Map 32 - Activating exit switch through the wall.
Map 17 - Activating switch behind yellow key door.
Map 19 - Activating switch inside the first house through the wall.
Plutonia: Map 04 - Activating exit switch.
TNT Evilution: Map 10 - Activating exit switch through the wall.
Also several custom wad levels.
I'd will also note that it is very unlikely that someone would discover this by accident. It would only really make sense for someone to do it by accident on Doom II Map 07 (Dead Simple), and there is a very specific position and angle that is needed for it to work. Getting the right angle\direction alone would be 1/2048, you would also have to be on the very edge and essentially be missing the exit linedef you are trying to press.
