Probability of BFG9000 to oneshot Cyberdemon with ZDoom RNG

[Combinebobnt]

The BFG with zdoom random can theoretically do alot of damage so we wanted to figure out the chance of oneshotting a cyberdemon with it (impossible in vanilla I think). We ran a script calculating the damage for 100+ million runs but never got a 4000, so it needed some math estimation to get an answer...

Got 0.00000000000000000323‬ % chance as an answer. Hope the math is correct!

 

I didn't find anything about this on the googleinterwebs so the people must know.

I can't check the maths for you, but I can report I've had exactly one one-shot kill with a standard BFG9000 on an undamaged Cyberdemon playing ZDoom in my entire playing career. I was pretty lucky even by that standard, too, as I was point-blank in a corridor and didn't know he'd be there and almost definitely would've died if he didn't. It was one of the Zort WADs by Cyb and it was probably 14-15 years ago, on either ZDoom 1.22 or 2.0.63a.

 

So yeah, it is possible, but it is terribly unlikely.

So you're telling me there's a chance...

A two shot for any boss monster is a dream for me. I can hardly get the BFG to do the job in the appropriate number of shots.

I swear I just pick up shitty BFGs that somehow managed to pass QC testing. It feels like it takes 10 fucking BFG balls before the bastards go down sometimes, even when they’re in the cone.

 

I think they might be Chinese knockoff models and mappers just place them around to save a few bucks, cut corners, thinking I won’t notice.. I’m onto you cheapskates!!

Its a 0 followed by 20 digits, that's almost a sextillionth wich is 21 digits, so the probability to one shot a cybie with a BFG in ZDoom is much more likely to be 0 than to see it happening once in our lifetimes.

I've read a countless deep dive articles on the BFG's programming, and I still can't get it to work that effectively. Shoot ball, turn in whatever direction target enemy is in, situate within cone of destruction, get disappointed. I mean, I can hardly wipe out a medium mob of imps and a revenant. I've tried moderating angle, speed, approach, not much of a change. Typically I put those 40 cells to better use with the plasma rifle.

See this video. I understood BFG's use from this video.

 

[Job]

It's a good video, but I already saw it. :I Maybe I'm just not effectively implementing the tactics. 

[Andromeda]

I'm surprised it's even possible!

1) "Looks inside the document."

2) "Runs away in panic."

 

Yeah, I'll just assume you are correct.

 

The sad part is that if this had already happened to somebody, they probably don't realize that they are the luckiest human on Earth.

You will have much better luck swapping the first and second step here.

Pro-est of pro BFG strats: there's a rather long delay between the moment you pull the trigger, and the moment the ball is launched. Monsters do not hear the ball being launched, they hear you pulling the trigger. So use the delay to cheese the monsters! Get in front of a door, shoot, then open the door. The door finishes opening, and a BFG ball flies in the room. Monsters get blasted to bits and they don't even notice. Likewise for teleporters: pull the trigger, step on the teleporter, you move to some other place, the ball is shot then and monsters explode.

 

On some levels with large enough areas, you can even do crazy stuff like shoot a bunch of BFG balls in the void, then run to a building, open a door, and let the tracers mow through a massive crowd of monsters repeatedly, it's pretty fun.

It has, and I would, but that lottery win is still pending.
