Does this challenge make it possible for skinny rooms be adjacent to other rooms now or is that still a set rule?

the void but normal

Ah, makes sense, makes sense. That's probably what's causing problems then! Makes sense tbh

I don't think this mod is supposed to be Rep compatible
MinerTurtle45 15 Jun, 2021 @ 8:34pm 
Really fun and interesting! Kinda easy to get OP with a guaranteed angel item from each floor if you explore enough to find the Ultra Secret Room (which is also sometimes required, obviously), but it's fun regardless! Did get the same bug as JaBoiVincent, however, where the trapdoor to the Womb doesn't spawn. Wish i knew *anything* about Isaac modding to help. :reheart:

i was talking about iksDi's comment, but i didn't know floor generation couldn0t be touched
AgentCucco  [author] 24 May, 2021 @ 12:50am 
That's not really how this mod works, it doesn't change generation at all, it just randomizes room placement. Right now we don't have the tools to change floor generation.

Though even if we did, this mod was just made as a proof of concept and nothing really more than that.

here's an idea for balance:


Curse of the Puzzle

Rooms are generated as normal, then shuffled, secret rooms still follow the same rules and will modify adjacent rooms to make sure of it
if a secret room needs to be crossed to go to the boss room/tresure room, a double bomb pickup, or the "i can see forever" pill will be a guaranteed pickup
iksDi 15 May, 2021 @ 10:36am 
That's interesting. I think it's would be fun as a sort of curse also. Probably will require a bit of balance for that, maybe like spawn 3-5 bombs in starting room/increased bomb drop rate as room clear reward and the ability to appear in chapters 2-3 only since the player probably won't have a bunch of bombs at 1 and starting from 4 chapter levels get too big for that. :yazdsmile:

What?
isaacOXIN⁴² 28 Apr, 2019 @ 5:32am 
Don't know how to make random sprites for items?
AgentCucco  [author] 18 Mar, 2019 @ 4:19pm 
That's weird, I'm pretty sure I made a failsafe for that.
Ashe I Guess 18 Mar, 2019 @ 10:05am 
there didnt spawn a trapdoor on the mom floor for me
V 12 Mar, 2019 @ 3:51pm 
Ahhhh, I wasn't aware those were starting items, if so, I think I'll try this out. Thank you however! ^-^
AgentCucco  [author] 12 Mar, 2019 @ 3:18pm 
It is sort of intended, that's the main reason why I gave Dad's key and sharp plug as starting items :P
V 12 Mar, 2019 @ 2:39pm 
I have been eyeing this mod for awhile but the scariest part of this mod in my opinion is sometimes secret rooms are -required- to complete a floor. Making it where if you do not have bombs or even know where the secret room is, gg. xD

Possibly one of the spookiest mods I have been considering for a bit now.
AgentCucco  [author] 22 Feb, 2019 @ 9:12am 
Glad you are enjoying it thus far :P
Zamie 21 Feb, 2019 @ 7:36pm 
This is the best mod to come out this year IMHO. I'm going to try to speedrun it.
AgentCucco  [author] 2 Feb, 2019 @ 12:15pm 
It can, I think, although I remember having trouble getting the indexes of those rooms, and by having trouble I mean my game literally crashing, lmao.
Still, by that point more than hard it would be a bit unfair.
violetjuliett 2 Feb, 2019 @ 8:14am 
ik, its more of a question statement. can it spawn there? because then it would be much harder. i assume no though...?
AgentCucco  [author] 30 Jan, 2019 @ 10:29am 
That would defeat the purpose, while also making it almost impossible to get out of a floor.
violetjuliett 30 Jan, 2019 @ 9:09am 
what if the trapdoor was in the angel room, devil deal, or I AM ERROR room?
AgentCucco  [author] 29 Jan, 2019 @ 9:44pm 
> When you showed it off.
Excuse me, if I recall correctly, we discovered this together, not just you on your own and then me taking credit for it, I was the one messing with the room descriptor and the room descriptor data for hours until you figured out you could copy and paste data from one room to another, lmao.
Anyway you still do deserve credit (although not all of it, lol) :P
Piber 29 Jan, 2019 @ 9:32pm 
i am a bit peeved that im not mentioned anywhere, but this is a pretty good showcase of the thing i found anyway. he started playing around with it too once i showed it off, and made this. basically i discovered something in the mod api that can be exploited and now mods are able to replace a room with another room. a pretty big breakthrough for a mod api that doesn't give any support for custom floors.

this has even bigger potential too, you can actually save room layouts from the previous floors and apply them to later floors. this means mods can do things like put treasure rooms in void, or have like 10 different boss rooms in a row. really cool shit.
Platnium 29 Jan, 2019 @ 4:11pm 
Really fun mod!
I made a custom challenge for it with deck of cards and starter deck (you have to spawn 2 bombs when you start the challenge)
<challenge name="Floor Randomizer" startingitems="63,85,251,238,239,327,328" startingtrinkets="3" endstage="12" megasatan="true" cursefilter="4" startingcard="13"/>
AgentCucco  [author] 29 Jan, 2019 @ 1:09pm 
Bear in mind that secret rooms (and top secret rooms) might hold other exits, perhaps you didn't get to explore a bit of the map and it happened to be the bit that holded the trap door.
marc072002 29 Jan, 2019 @ 1:04pm 
well it worked one time, nice mod tho! but in one run or 2 i couldn't find the trapdoor... even in the secret rooms! and no, i'm not using revelations
AgentCucco  [author] 29 Jan, 2019 @ 12:25pm 
@marcbg Trapdoors don't usually spawn on the boss room, you have to search for the original location of the boss room in the map to actually find the trapdoor.
The original boss room might get replaced by a secret/treasure room or even a default room, but the hatch will remain there.
AgentCucco  [author] 29 Jan, 2019 @ 12:24pm 
Oh my lord, don't use Revelations with this mod, Revelations does rooms via lua and not like the normal floors actually generate, entering Glacier or Tomb with this mod will entirely break everything.
PhotoFinn 29 Jan, 2019 @ 12:20pm 
Do you have any mods that change or add new rooms? It was happening to me too because I was using Revelations
marc072002 29 Jan, 2019 @ 12:18pm 
it's not spawning trapdoors...
AgentCucco  [author] 28 Jan, 2019 @ 5:04pm 
There shouldn't be any issue with 2 player mode I don't think, it's just randomizing the floor, nothing else.
Senku1507 28 Jan, 2019 @ 1:42pm 
i gonna try it i hope it works thanks. It works with 2 player mod?
AgentCucco  [author] 28 Jan, 2019 @ 8:05am 
Gg
WitchAmy 28 Jan, 2019 @ 8:00am 
@AgentCucco I've just got Dr. Fetus and IPECAC on Basement XL lmao
AgentCucco  [author] 28 Jan, 2019 @ 5:14am 
@CepayReel Вот почему вы получаете отцовский ключ + Батарея + Острый штекер, а также бомбы Bogo, также обратите внимание, что задача в обычном режиме, поэтому теоретически вы должны получить больше расходных материалов, чем обычно.

For other people I'd rather for you to comment in english since google translate can be a bit dumb sometimes, lmao.
CepayReel 28 Jan, 2019 @ 3:25am 
тоесть в любом случае понадобица не одна бомба на один этаж
AgentCucco  [author] 27 Jan, 2019 @ 8:34am 
Thanks for reporting, I'll try and fix that later (Also how did you manage to get to Hush with this mod on, it took me like 10 minutes to get to the caves myself, lmao).
WitchAmy 27 Jan, 2019 @ 2:01am 
One more bug: Mom doesn't drop Polaroid/Negative so you will end challenge either on Sheol/Cathedral or in The Void if you decide to go kill Hush
AgentCucco  [author] 26 Jan, 2019 @ 9:37pm 
Yeah I've tried everything to generate new rooms within the existing floor layout and nothing seems to work, sadly.
Granted I'm using this same proof of concept to make a trinket that guarantees a special library almost every floor :P
PhotoFinn 26 Jan, 2019 @ 5:15pm 
This has the potential to be amazing if you decide to continue updating this concept! Universal Item Pools would be cool and random room types ala Red Key would be sick (but probably impossible with the current api)

That said this is already great, I get a strong Castlevania/Rogue Legacy vibe from it
Ms Mowz 26 Jan, 2019 @ 11:41am 
I'll check my mods that's probley the problem.
AgentCucco  [author] 26 Jan, 2019 @ 10:38am 
Thanks for reporting the Mom bug, also as for the secret rooms thing, giving the player blue map would defeat the purpose, the player starts with Dad's key and Sharp plug for a reason :P
WitchAmy 26 Jan, 2019 @ 10:31am 
BTW if you decide to go defeat Mom, it's impossible to complete the challenge unless you have teleport stuff.
WitchAmy 26 Jan, 2019 @ 10:23am 
I think player should also start with Blue Map as sometimes you could end up with trapdoor in Secret Room while having 0 bombs and nothing like Dad's Key etc.
AgentCucco  [author] 26 Jan, 2019 @ 8:26am 
That's odd, do you happen to have any other mods installed that change something on a new level?
Second, are you sure the floor is entirely normal without any rooms scrambled or anything? And if so, do you have any errors show up in the console when you attempt to play the run?
Ms Mowz 26 Jan, 2019 @ 5:28am 
I know that It's when I play the chanllege nothing changes its just a normal run with the key and lord of the pit.
AgentCucco  [author] 26 Jan, 2019 @ 5:14am 
@That annoying guide, It is called a "challenge", meaning it's in the modded challenges menu, the game won't normally randomize the floors unless you play the designed challenge.
AgentCucco  [author] 26 Jan, 2019 @ 5:13am 
@Lemon Demon, Thanks for reporting the bug, I basically forgot to disable a Dev function :P
Ms Mowz 25 Jan, 2019 @ 4:33pm 
It's not doing anything for me just a normal game with extra stuff.
