Questions and Feature suggestions
I'll grup all the questions and feature suggestions here, so people have one place to see everything that was asked/suggested

Common Suggestions:
- Add/change Hp: it's planned
- Multiple modifiers: it's planned.
- Multiple conditionals: Also planned.
- Random Rule generated: already planned, just really low priority, it may or may not happen.

Take in mind that "planned" doesnt mean that I'll do it, it means that I plan to do it. As a normal human being with fluctuating interests, my plans and the priorities of said plans change. If you want a relatable explanation, in the same way you get burnt out of mods, so do mod devs.

Common Questions:
BEFORE ASKING ANYTHING, click the "?" icon on the top left of the menu, maybe your answer is there.

-Is there a game-wise timer(for hush n stuff)?
Yes, the delay special.

-How do I make a "Every item rule?"
0. Press J on the starting room.
1. Create a new rule
2. Click on the on the white paper on left side of the arrow
3. You'll now be in the entity selection screen
4. Click the title box on the top
5. Select the Red question mark
6. Look for "All Items" and click it (Red Question mark on a pedestal) then select "All Items No Quest"
7. Click on the "Forbidden" red icon/pin on top of the white paper on the left side of the arrow. The paper should turn red and be crossed out.
8. Click on the white paper on right side of the arrow
9. Click the title and select the sad onion icon
10. Select the item you want to replace all items with.
11. DONE

For example, this is how every item is sad onion looks like:

Turn on the rule generation feature
I really love procedural generation and want to test this function
Герой2018 Mar 27, 2021 @ 12:48pm 
ok, I'll wait then it's all the same what kind of command you enter to enable this function

I have some questions!
Can you remove a pill?
If so, how does it work; does it pick a different one to replace it or will there be 1 less type of pill encountered?

Can you change the pill rules so you can choose how many "good" + "meme" + "bad" pills there will be? For example if I want to have most of the pills in the pool "good" and have less"meme" ones or "bad" ones, or vice versa.

Can you change curse frequency?
Can you remove certain curses from the pool?

Can you choose alt floor chance example how often downpour will be replaced with dross?

Can you make certain characters start with certain trinkets?

I assume you can remove items, but can you remove them from specific pools?
Can you add items to certain item pools?

Can you modify guillotine so that the head is stationary?

That's all for now, thanks :steamhappy:

Yes, but no....you cannot remove a pill by it's effect but by it's color, thats just how the game works.

No

No

Kind of but not really, you can make it so as you enter a certain floor you get teleported to another.

Yes

No

I think so

timer question
is there a way to change the timer so that i can make it on time for stuff like hush or boss rush etc
Revalopod May 16, 2021 @ 8:32am 
ok 1 quick question if you don't mind

Can you modify an active item charge eg. make a 4 charge item into 2 charge instead
Revalopod May 16, 2021 @ 9:29am

Liberto May 23, 2021 @ 2:02am 
Multiple Modifiers

I hope the dev sees this

when i was using the rules menu i realized when i try to make a heart turn into another type of heart or make a shopkeeper turn into a penny it just spawned them both in the same area instead of replacing them like i thought it would, am i just dumb and dont know how to make stuff replace stuff instead of just triggering them spawning or is that not a feature, if it isnt then i guess i suggest that; maybe add a *thing* is replaced by *thing* rule, and another suggestion; i noticed when i clicked a pickup it was the pickup and all variants, maybe there could be a way to make it one specific type instead of all variants

I mean, you see in the thumbnail that stuff is striked right?....anyway, just right click the left-side entity (the one on the left side of the arrow) to trigger replace mode
Also click the "?" icon on the top right.

i just thought the strike thing just made those things not spawn

I spent some minutes looking but I think there is no option to do that

- please add a way of making it spawn an item pedestal on the ground and I can say if it's going to be in a random position or a specific one, and it's item pool (if it's gonna be the current room or some other one)

- a way of making it use a specific active item EFFECT even if I am not holding it (same for pill effects)

- a way to give the player a trinket as a consequence (there's only an option to give an item)

- Thats already a thing.
- Thats planned but I keep forgetting trinkets exist, lol.
honestly does anyone remember about trinkets??

A little help here? I'm trying to make it so when a bomb explodes the devil statue, the devil sattue will dissapear, spawn a fallen gabriel labeled with DD, and when this fallen gabriel labeled with DD dies it executes the command "spawn 5.100" which spawns a item pedestal from the current room item pool
I tried to do it like this (the top two are them, I also tried inverting the order of them but it didn't work) https://i.imgur.com/Cd4rI73.png
I explode a bomb next to the devil statue but nothing happens,what am I doing wrong? Because I have no idea
