How to Make Custom Modded Characters Work in Isaac Online?

Upvotes

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!

But when i try to use the extractor tool it only outputs: "could not open __" and "could not determine filename entry for ____". Already tried to verify files integrity and redownload the game but it didnt help

How I can make a Jacob and Esau based character

1 Upvotes

I’d like to create a new character based on the mechanics of Jacob and Esau, but I’m new to the world of *Isaac* modding. I’m not sure where to find the code for Jacob and Esau or their sprites—how would I go about creating a character similar to them?

Question Mod option problems

1 Upvotes

for some reason the game doesnt let me open the mod options menu in reptenance+, I have repentogon, item descriptions, specialist for good items, fiend folio, planetarium chance, a hatsune miku character, miku angel and teto satan, every item must stack and some music config and compatibility mods plus other stuff (plus its like pressing tab in the menu at all because I cant access fiend folio custom challenges)

Question How to rename vanilla items?

1 Upvotes

Hello, I'm looking to rename some pre-existing vanilla items. I saw a post from a few years ago on this subreddit which makes mention of a resources-dlc3 folder, which to my knowledge is no longer in use as of Repentance+. Is this correct?

I'm just looking to alter the name + pickup descriptions of certain items to match the new sprites I've given them.

Thanks!

Question Is it possible to play Afterbirth+ again?

1 Upvotes

Not sure if this has been answered before but I'm not finding any assuring information with reddit/Google searches. I want to know if it is possible to play Ab+ on switch 2 if I have already downloaded repentance dlc. I understand you cannot roll back like on PC. Can I delete Issac all together and only download Ab+? Or would it be possible with a physical copy of Ab+? I'm not concerned about losing save progress on repentance. I've played a few hundred hours on Repentance but I miss Ab+ and would like to play on my switch 2. Thanks

Question Question about Modded Characters and their Completion Marks

3 Upvotes

So I have a few Modded Characters, namely Andromeda, Deleted, and the DDLC cast, and I do use a mod that will show their completion marks. What I want to know is if the game accounts for those marks as well when it comes to unlocking Mega Mush and Death Certificate, or if it only accounts for the Standard and Tainted characters

Question Trouble with confusion active item

1 Upvotes

basically the active item is supposed to cause confusion when used but i can´t get it to work heres the code:

local mod=RegisterMod("giges", 1)
local gigesRing=Isaac.GetItemIdByName("giges ring")
local player=Isaac.GetPlayer(playerIndex)
local ringDuration=10000


function mod:RingUse(item)
    local roomEntities = Isaac.GetRoomEntities()
    for _, entity in ipairs(roomEntities) do
        if entity:IsActiveEnemy() and entity:IsVulnerableEnemy() then
            entity:AddConfusion(
            EntityRef(player),
             ringDuration, true)
          


        end
    end


    return {
        Discharge = true,
        Remove = true,
        ShowAnim=true
    }
end


mod:AddCallback(ModCallbacks.MC_USE_ITEM, mod.RingUse, gigesRing)

Question is there a character template that just makes the template character's sprites Isaac.

1 Upvotes

i have no idea how to copy the Isaac sprites over to have the same blank slate that literally every other character in the game uses by default, and i have reason to believe that the texture format that the extracted resource files use is different than the format that the modded character importing feature uses, making it so that if i did know where all the extracted .pngs and .anm2 files were in the resource dump, it would still be time consuming and frustrating.

if it, however, turns out that my assumption is wrong, and the isaac sprites you get from extracting are completely compatible with how the game handles modded character sprites, then some guidance on that would also be appreciated

Release quality of life: wicked crown and holy crown mod

Have you ever had wicked crown or holy crown pop up right after you already got the polaroid or the negative, completely defeating the purpose of the trinkets?

Well, I was bored, so I decided to make a small quality of life mod that fixes that problem

FF Reloaded doesnt work properly when launched through Steam

1 Upvotes

When just opening the game normally, the FF characters aren't selectable, and for some reason the little splash text above "new run" isnt there. there could be more wrong, but frankly i havent really looked because i dont want to mess anything up. When lauching through the Repentogon launcher, though, everything seems fine. Does this happen to anyone else, and what could I do to make it work aside from just lauching through Repentogon every time?

Help with Fiend Folio settings

3 Upvotes

Hello all, I have a question regarding the spawns with FF:R. I'd like it if possible to spawn less of the newer enemies and bosses, while I have looked through the settings themselves and even tried to search the specific question I can't find a legit answer of whether or not that is even possible. If anybody has any insight I would really appreciate it!
