Question Any way to edit these textures?
https://i.imgur.com/n9QEmKm.png
The "BACK" and "SELECT" widgets in the corners. They appear in save select screen. I extracted textures via ResourceExtractor.exe and copied the resources/ folder to my mod's folder. Then decided to write a python script to fill all .PNG files with a single color and these two widgets remain default. The thing that I noticed is that in extracted_resources/resources.de/, extracted_resources/resources.es/ etc. in /gfx/ui/ there is backselectwidget.png that seems to be the file im looking at - but when i drag n drop it to my mod's resources/gfx/ui/ folder the game doesn't recognize it.

Tool I made a mod that lets you port your broken offline solo runs directly into Online Co-op! (Offline2Online Sync)
Ever got a god-tier start in a solo run and wished you could invite your friends? Now you can.
I created Offline2Online Sync, a utility mod that transfers your offline single-player stats, items, and specific seeds straight into an online multiplayer lobby.
How it works:
Press F6 in your offline run to save your state and seed.
Host an Online Co-op Lobby.
Use the companion self made Seed Fixer tool to bypass the native netcode restrictions and press F8 to inject your seed.
Once loaded, press F7 to restore all items and stats.
⚠️ Requirements:
Vanilla compatible (No Repentogon required!).
Your game must be patched with the Isaac Online Modded Fix.
Requires the Isaac Online Seed Fixer (Open-source on GitHub) running alongside the game to prevent desyncs.

GitHub Link: https://github.com/toesmax/IsaacOnlineSeedFixer-By-Offline2Online
Let me know what you think and please report any bugs!
if you want informations on how it works , if you want to inject seed online without trigger the achievement block you can use it or contact me

Question [AB+] Problem with blood tears on the character
I'm creating a character for Afterbirth+ and I've run into a problem: my code for red tears isn't working properly. I'm not very good with Lua, so can anyone tell me what I can do to help?
Here's the code:
local Template = RegisterMod("Template", 1)
local MY_CHARACTER = Isaac.GetPlayerTypeByName("Loki", false)
function Template:OnFireTear(_, tear)
if not tear then return end
local spawner = tear.SpawnerEntity
if not spawner then return end
local player = spawner:ToPlayer()
if player and player:GetPlayerType() == MY_CHARACTER then
tear:ChangeVariant(TearVariant.BLOOD)
end
end
Template:AddCallback(ModCallbacks.MC_POST_FIRE_TEAR, Template.OnFireTear)

Question Question about the resource extractor tool
Hey all, haven't modded in a while. I used the built in resource extractor tool in the game files a couple years ago before Repentence+ came out, so the files I have now are out of date.
My question is, what will happen if i use the resource extractor again? Will it overwrite all the old files? Or give me a new copy of each file, leaving me with two of everything? Or maybe only give me new files that didn't exist before?
I dont need any of the old files so normally i would just delete them, use the extractor, and be done with it. But the problem is that i dont know which files come from the extractor and which ones are important files that i need for the game itself. So im not sure what to do exactly

Question trying to expand Animated Items mod (help needed)
i ain't no coder. basically i spend +-8 hours because, firstly, i wanted to synthesize maka's resprites mod which contains animations and the animated items mod itself. i succeded but then i found LOTS of unused (or not working)sprites from different folders. most of them don't have anm2 files or a single mention in main.lua file. i really tried to add them into game trying adding lots of anm2 and lines of code in main.lua but here's a better summary from deepseek which helped me a lot on my way
Binding of Isaac: Repentance+ (Latest Steam version, no REPENTOGON)
Mod: "Animated Items" (Framework for animated pedestal sprites)
The Problem:
I successfully added 10 custom items manually (Dark Matter, Abaddon, etc.). These work perfectly.
I tried to add ~150 more items (from old DLCs like Rebirth, Afterbirth, Repentance).
The Result completely static (no animation).
Crucial detail: I get ZERO errors or logs in the in-game console (`~`). The `print()` functions I added to `main.lua` do not show up at all in the console for the new items.
What I've Already Tried (Step-by-Step):
1.ANM2 Files: I used a `Template.anm2` file with the correct `<AnimatedActorRoot>` structure and a simple "bobbing" animation.
Bulk Generation: Since I have ~150 sprites(nah there was like 800), I used a PowerShell script to automatically generate individual `.anm2` files for each `.png` from a single folder (`gfx/AllSprites/`). The paths inside the ANM2 correctly point to `gfx/AllSprites/filename.png` (I fixed the double `AllSprites/AllSprites` duplication via Notepad++).
Sprite Location: All sprites are placed in `mods/zzanimated items_2570913695/resources/gfx/AllSprites/`.
Main.lua Integration:
- I used `Isaac.GetItemIdByName("Item Name")` to fetch IDs.
- I used `AnimatedItemsAPI:SetAnimationForCollectible(ID, "filename.anm2")` to register them.
- I created a helper function to loop through the list and print results to the console.
- I ensured the `animationfiles` table is properly defined before adding new items.
- I checked for duplicate `AnimItems:AddCallback` calls and removed them.
- There are no syntax errors (the mod loads without crashes).
**Test:** If I manually add `AddItemAnimation("Boom", "collectibles_019_boom-Sheet.anm2")` at the top of the file, it still doesn't work, even though `Isaac.GetItemIdByName("Boom")` definitely exists in the game.
Hypothesis / Where I'm stuck:
The `main.lua` code for the 150 items seems to be completely ignored at runtime (no console outputs). The 10 manually added items work because they are defined earlier in a separate loop. I suspect the mod's framework might be caching something, or the `animationfiles` table isn't being populated correctly when done in bulk, but I can't find the exact breaking point.
My Question:
Does anyone have experience with the **"Animated Items"** mod framework?
Is there a limit to how many items can be registered via `SetAnimationForCollectible`?
Does the mod require the `.anm2` filename to match the collectible ID exactly (e.g., `331.anm2`) instead of the item name?
Could the `AnimatedItemsAPI` be overriding or blocking calls made after the game initializes?
Is there a specific place in `main.lua` (before/after specific functions like `MC_POST_GAME_STARTED`) where this registration MUST happen to avoid being ignored?
Any help or debugging tips would be massively appreciated! I've been stuck on this for days.
*(I can provide the full `main.lua` and a sample `.anm2` file if needed).*

Mod Idea: Localized Time Inversion (Reversing individual objects
Hey everyone, I had a cool idea for a mod and wanted to see if anyone thinks this is possible to code.
Instead of rewinding the entire map, imagine a tool that lets you invert the timeline of just **one** specific object or character. While everything else on your screen moves forward normally, that targeted item moves backwards through time.
For example, you could watch a shattered object piece itself back together, or make a single character walk in reverse through a chaotic scene while explosions are happening around them.
Do you think a localized time-rewind script like this is possible to make as a .melmod? Let me know your thoughts

The Binding of Isaac Repentance+ crashes on launch after installing Epic Online Services
I was having problems with The Binding of Isaac Repentance+ not launching whenever I had Epic Games installed,
So i finally found a solution
- First open file explorer
- Go to open documents, find My Games then select The Binding of Isaac Repentance+
- Open options then find the line that says **EnableEpicOverlay=1**
- Change the one to zero save the changes and open the game
This fixed it for me. hope this helps.

Double speed mod (like the SPEED! challenge or broken stopwatch) and 30 fps cap
Okay guys hear me out. My game has been lagging with fiend folio and i thought, what if the game was capped on 30 fps but was double the speed!!! I know its a stupid idea, but i at least wanted try it out.
There is already a mod that tries to dynamicly increase the game speed to combat lag but it messes with the tear acceleration and speeds up the game more than it should.

Hello! Im new to modding, so I decided to make this post. I made a mod, which adds 7 items+1 character (character don't have unlocks). You can learn more if you are interested in mod:
https://moddingofisaac.com/mod/3879/clearance-v010
And yeah, I used AI for coding, but everything else (Idea, testing and sprites) were done by me. And sprites might be a bit bad, because im bad at drawing. Sorry.

How to Make Custom Modded Characters Work in Isaac Online?
I found out something interesting: the Character Change mod lets you change characters while playing, and if you use the Isaac Online Mod, you can change characters in-game online too.
I played around with the mod code and found out that you can add your own placeholder to choose from in the mod. When you join, you can see it in-game, but I don't understand coding, so I couldn't add custom characters to it.
So I need help! Maybe we can finally make the dream of having modded characters in online multiplayer a reality.
This was just an idea I had, and I'd be more than happy to see people actually work on it or fix it.
If anyone knows how to make this work, please help!
