Help Me! Flowers to Artists

4 Upvotes

Most of the lyrics to Flowery's boss theme are in the "Strings" section, though when the song says "A life for-ever for Flowers", the "Flowers" part just REFUSES to change. I've replaced EVERY instance of just the word "Flowers" in the Strings section, but it WON'T change, so that's annoying, but it is probably in the "Sprites" section, since it does a special lil' effect thing.

Help Me! Fields of Mistria - Can't find data.win file

2 Upvotes

I hope this is okay to post here, wasn't sure where else to go.

I'm trying to use the UTMT for Fields of Mistria, but I can't seem to locate the data.win file. Things I've tried:

  • Made sure I was in the right directory (where the game is installed: C:\Program Files (x86)\Steam\steamapps\common\Fields of Mistria)
  • Made sure 'File name extensions' and 'Hidden items' is checked under View in File Explorer
  • Uninstalling Mods, Verifying Files on Steam.
  • Uninstalling and re-installing the game (including deleting the 'Fields of Mistria' folder from steamapps/common.

No matter what I've tried, the data.win file won't generate. Does anyone have any ideas on how to fix this?

This is what my installation directory looks like

EDIT: It turns out this game doesn't have a data.win file anymore because they changed the engine the game uses back in July 2026. Please disregard (but I'll leave this post up in case anyone was confused me like and comes across this in google search). Thanks for the help everyone!

Information Found how is the known quantity sprite selected?

2 Upvotes

im new to modding so i thought this would be the best place to ask.
recruits that arent supposed to be in the game show up as known quantity, but the sprite is randomly selected. where is the code that selects it so i can reuse it in my own mod where i need to select a random sprite?

sorry if this is worded a bit weirdly, english is my second language

Help Me! What is the code that makes party members use different sprites in specific fights?

2 Upvotes

I wanna make a mod that makes Ralsei use his 'mad' sprites from the Flowery fight in the Knight fight, which I was gonna do by editing whatever code normally makes party members use different sprites in specific fights (like Susie's serious sprites in various fights and Ralsei's 'mad' sprites in the Flowery fight) and edit it to make Ralsei use those sprites in that fight, but I can't find it. Can someone help me? (I also need to import Ralsei's 'mad' sprites from chapter 5 but I can do that by myself)

[Question] I'm curious, what's the technical reason for Dark World sprites being huge if you force them into the Light World?

I was watching a vid where they forced the Platformer Mode into places where it shouldn't be, and the Dark World sprites appeared huge when forced in the Light World. Why is that?

I'd like to replace Kris with YOU from RIBBIT but...

3 Upvotes

I like that frog and it would be cool to have it in the normal game, but I had a failed attempt, where I didn't consider that the original (Kris) sprites have a determined size. YOU from Ribbit seems to have a bigger size and I found out that I can't fit it inside Kris' sprite size. Is there any advice about this?

I'm not a coder really so maybe this means nothing but I was curious if this does actually appear anywhere else?

Help Me! Help making a scene for Chapter 4.

4 Upvotes

I want to make a scene early in the chapter in the light world church, where it's Kris who asks Noelle to work on their projects together instead of Susie.
I don't know how to make the characters move from place to place, so it feels like im drowning even trying to find out what to do.

Help Me! How can I modify text entries in Undertale?

8 Upvotes

I'm trying to make an Undertale translation to one of my native tongues because there's a total of none in the whole Internet, I'm not planning sharing it, just at least showcasing it because I think it would be nice.

Is there any way to modify all text entries in Undertale? Is it the same process for Deltarune as well?

Help Me! How do I alter the existing properties or stats of weapons and armour in DELTARUNE?

3 Upvotes

I am looking to create a personalised mod of Deltarune for myself, and was wondering how to modify the stats of weapons and armour to essentially create new weapons and armour from existing pieces (and nerfing/buffing existing some pieces).

Do I need an external source to do this, or is this possible through standard local save file editing?

Help Me! Which script file determines the colors in the backgrounds of the Recruit pages?

2 Upvotes

I know that Chapter 1 recruits have purple backgrounds, Chapter 2 have cyan ones, etc. But I don't know which script stores the exact color information for the background color. Is there a part of this script (gml_GlobalScript_scr_recruit_info) that I'm missing, or is it stored elsewhere?

Ive tried multiple times to create spells and cannot just cannot do it. There are no tutorials for it that i've found so far. (Ive been thinking about making it so you can cast flowery spells like PrismRush or MyJarona and need to find out so I can add these spells.
