Since i didn't see any definitive breakdown on getting Devil Rooms to spawn that is actually confirmed for Rebirth, i looked at the game code myself and this is what i came up with. (You can substitute Devil with Angel for the rest of this, this is the calculation to make a door spawn, but it has no influence over which of the two it is.) The game checks the chance to spawn the door when you beat the boss and every time you enter the boss room after that, on floors 2 through 8. If at any point the door fails to spawn, it will never spawn again for that floor. The only exception is Goat Head, since it circumvents the whole chance calculation and can even re-open a "failed" spawn. The chance to spawn the door goes like this:
After this whole thing comes Goat Head and says "Whatevs man, i go straight to the goal, i don't care about all this math." HenryEx fucked around with this message at 19:45 on Jul 8, 2015 |

Wait so I'm reading this right, if you have the Book of Belial and run in/out of the boss room enough times the devil room will eventually close? Not that there's much reason to do that or whatever. I'd just test it out myself to see how many times it'd take but I'm on mobile at the moment. e: So the "evil up" part of black candle does actually increase your devil room chance? Does the rosary/bible tract make angel rooms more common then, or devil rooms if you've locked those in since their description is just "faith up"? Rosary Bead I think we know already does increase angel room chance specifically, but now I'm curious if the others influence anything.

Not that there's much reason to do that or whatever. (2500% + 1%) * 0.25 > 100% (ie the lowest it can go is still certain), it's essentially an "always spawn" thing except it doesn't force it to spawn if it didn't already.

The above is just the game's calculation whether "The Door" spawns or not. Which one it ultimately is, Devil or Angel room, is decided at a different place. I don't have a good grasp on the chances for/against an Angel room yet or whether the items that increase Angel room chance even stack, but i DO know that having the Rosary Bead or Key Piece 1/2 give better odds at Angel rooms. Here's a fun thing i've learned today: Donating ten or more coins at the Donation Machine increases your odds of getting an Angel room instead of a Devil room!

It brings joy to my heart knowing that others are doing this, and not me. ...Of course, I kinda wish I could look myself but it's all obfuscated to hell and I haven't bothered to go looking to see if others have simplified/labeled it or anything.

If you alt+f4 before the game over screen shows up you can restart from the start of the floor. That's how I did it.

So, without steam achievement manager (running linux) I know I need that flaming heart item from the angel rooms, but there's probably a bunch of other things. Is there a guide to getting all the Rebirth steps finished to finally achieve Real Platinum God? Steam vaguely says "Locked Achievements: +2", but I don't know if I trust that page.

You can see which items you need to touch by going into the stats and viewing the items. Any with a ? need to be touched and you can compare it to http://platinumgod.co.uk/rebirth Click the gear in the upper-right and order by: id They then both match up item for item

for the very first time I got to the chest and beat the blue baby! I had a nice run as cain. proptosis, shielded, rubber tears with about four damage up items made it doable. im really glad I took the shielded tears item in the boss rush as that properly allowed me to stand next to Isaac and the baby and ignore their own tears. I took the polaroid with me. what happens if you take the negative? do you get a different chest? or a different ending after the chest? (I know I am massively behind everyone else but I am very bad at this game. I was on a -140 something losing streak before this)

If you take the poloroid you can go to the Chest after beating Isaac. If you grab the wrong one for the path, then the fights stop at Satan/Isaac. You won't go to The Chest/The Dark Room.

Hyphen-ated posted:Thanks! It's basically just a LUA script put into CheatEngine's "Make a trainer" feature. I'm not a coder, so i can't make actual programs. I can post the LUA script i'm using, but it's really only good to see what offsets in memory i check for values. I tried to improve the program a little bit, gave it an actual icon and made the text color change - it's default light blue for when a door can still spawn on this floor, it becomes dark red when it can't spawn anymore (seen it already and let it despawn) and it's light green when you have Goat Head and the percentage is meaningless. I also tried to make the window stay on top, but unsuccessfully... as i said, not actually a coder, just someone with access to internet tutorials. (It's still on the same link.) The program mimics the game in chance calculation exactly and reads the same values, but it doesn't know what influences those values! So if you ever see the chance increase on a floor without doing any of the list i posted, you found a new way to improve the devil chances.

Hm, i guess so - Cheat Engine has two modes to compile a trainer, Tiny and Gigantic. I used Tiny to keep the file size low, but it seems like you need CE installed to use these kinds of trainers then. I've compiled it again, as a Gigantic trainer, which should include the neccessary standalone code from Cheat Engine (and makes the thing ~4 MB big). It would be great if you could download it again and tell me if it works now without Cheat Engine installed.

Either way this is still a good tool to have.

Jibo posted:It seems like this counts red heart damage from curse room doors and blood banks which I'm pretty sure don't count against you when getting the door to appears. Either way this is still a good tool to have. This tool checks exactly the same variables in memory as the current game's code when trying to spawn a devil room - which means, it doesn't look for "did the player ever take red heart damage from these sources", it just checks for "was this variable at location x ever set to True?". The tool doesn't actually know what influences said variables, just that if they are set, the game will increase/decrease the chance by a certain amount. So, if the game sets said variable to True on entering curse rooms or doing blood donation, you can be pretty sure it'll count against getting a devil room. Due to the way it works, you can even test for what does or doesn't increase the chance, as long as it's not at 100% already. Does bombing the donation machine increase the chance? I don't know, i didn't test for that, but the tool checks all relevant variables in the game's memory, so if they're modified, the tool will display that! (This is how i found out about the shopkeepers, had it running, bombed one of them, the chance increased)

I believe red heart damage from curse rooms does indeed lower your devil room chance, but blood bank/devil beggar/portable blood bag do not lower your chances.
