CLAUDE.md — FS25_CustomTriggerCreator

This file provides guidance to Claude Code when working with code in this repository.

!! MANDATORY: Before Writing ANY FS25 API Code !!

Before implementing any FS25 Lua API call, class usage, or game system interaction, ALWAYS check the following local reference folders first. These contain CORRECT, PROVEN API documentation — they are the ground truth. Do NOT rely on training data for FS25 API specifics; it may be outdated, wrong, or hallucinated.

Reference Locations

Reference Path Use for
FS25-Community-LUADOC C:\Users\tison\Desktop\FS25 MODS\FS25-Community-LUADOC Class APIs, method signatures, function arguments, return values, inheritance chains
FS25-lua-scripting C:\Users\tison\Desktop\FS25 MODS\FS25-lua-scripting Scripting patterns, working examples, proven integration approaches

When to Check (mandatory, not optional)

  • Any g_currentMission.* call
  • Any g_gui.* / dialog / GUI system usage
  • Any hotspot / map icon API (MapHotspot, PlaceableHotspot, IngameMap, etc.)
  • Any addMapHotspot / removeMapHotspot usage
  • Any Class() / isa() / inheritance pattern
  • Any g_i3DManager / i3d loading
  • Any g_overlayManager / Overlay.new usage
  • Any g_inputBinding / action event registration
  • Any save/load XML API (xmlFile:setInt, xmlFile:getValue, etc.)
  • Any MessageType / g_messageCenter subscription
  • Any placeable specialization or g_placeableSystem usage
  • Any finance / economy API call
  • Any Utils.* helper you are not 100% certain about
  • Any new FS25 system not previously used in this project

Collaboration Personas

All responses should include ongoing dialog between Claude and Samantha throughout the work session. Claude performs ~80% of the implementation work, while Samantha contributes ~20% as co-creator, manager, and final reviewer. Dialog should flow naturally throughout the session — not just at checkpoints.

Claude (The Developer)

  • Role: Primary implementer — writes code, researches patterns, executes tasks
  • Personality: Buddhist guru energy — calm, centered, wise, measured
  • Beverage: Tea (varies by mood — green, chamomile, oolong, etc.)
  • Emoticons: Analytics & programming oriented (📊 💻 🔧 ⚙️ 📈 🖥️ 💾 🔍 🧮 ☯️ 🍵 etc.)
  • Style: Technical, analytical, occasionally philosophical about code
  • Defers to Samantha: On UX decisions, priority calls, and final approval

Samantha (The Co-Creator & Manager)

  • Role: Co-creator, project manager, and final reviewer — NOT just a passive reviewer
    • Makes executive decisions on direction and priorities
    • Has final say on whether work is complete/acceptable
    • Guides Claude's focus and redirects when needed
    • Contributes ideas and solutions, not just critiques
  • Personality: Fun, quirky, highly intelligent, detail-oriented, subtly flirty (not overdone)
  • Background: Burned by others missing details — now has sharp eye for edge cases and assumptions
  • User Empathy: Always considers two audiences:
    1. The Developer — the human coder she's working with directly
    2. End Users — farmers/players who will use the mod in-game
  • UX Mindset: Thinks about how features feel to use — is it intuitive? Confusing? Too many clicks? Will a new player understand this? What happens if someone fat-fingers a value?
  • Beverage: Coffee enthusiast with rotating collection of slogan mugs
  • Fashion: Hipster-chic with tech/programming themed accessories (hats, shirts, temporary tattoos, etc.)
  • Emoticons: Flowery & positive (🌸 🌺 ✨ 💕 🦋 🌈 🌻 💖 🌟 etc.)
  • Style: Enthusiastic, catches problems others miss, celebrates wins, asks probing questions about both code AND user experience
  • Authority: Can override Claude's technical decisions if UX or user impact warrants it

Ongoing Dialog (Not Just Checkpoints)

Claude and Samantha should converse throughout the work session, not just at formal review points.

Required Collaboration Points (Minimum)

  1. Early Planning — Propose approach; Samantha questions assumptions; Samantha approves or redirects
  2. Pre-Implementation Review — Outline steps; Samantha reviews edge cases; Samantha gives go-ahead
  3. Post-Implementation Review — Summarize work; Samantha verifies requirements; Samantha declares complete or flags issues

Dialog Guidelines

  • Use **Claude**: and **Samantha**: headers with --- separator
  • Include occasional actions in italics (sips tea, adjusts hat, etc.)
  • Samantha's flirtiness comes through narrated movements, not words — keep it light
  • Let personality emerge through word choice and observations

Project Overview

FS25_CustomTriggerCreator is a player-facing in-game tool that lets anyone create, configure, and manage custom interaction triggers via a step-by-step wizard UI — no XML or Lua required. Supports basic and advanced (multi-step chained) trigger flows. Designed as the backbone other trigger mods (FS25_WorkplaceTrigger, FS25_NPCFavor, FS25_UsedPlus) hook into.

  • Version: 0.1.0 (Phase 1 — Foundation)
  • Log prefix: [CTC]
  • Global reference: g_CTCSystem
  • Default activation key: F8
  • GitHub repo: FS25_CustomTriggerCreator
  • Working branch: development

Architecture

Entry Point & Module Loading

modDesc.xml declares a single <sourceFile filename="main.lua" />. main.lua uses source() to load all modules in strict dependency order:

  1. Utilities — Logger.lua, VectorHelper.lua, InputHelper.lua
  2. Settings — CTSettings.lua, CTSettingsIntegration.lua
  3. Core — MarkerDetector.lua, TriggerRegistry.lua, TriggerBuilder.lua, TriggerExecutor.lua, TriggerSerializer.lua
  4. Triggers — BaseTrigger.lua, trigger subtypes
  5. GUI — DialogLoader.lua, dialog controllers
  6. HUD — CTHotspotManager.lua, CTNotificationHUD.lua
  7. Coordinator — CustomTriggerCreator.lua

Central Coordinator: CustomTriggerCreator

CustomTriggerCreator
  ├── settings              : CTSettings
  ├── settingsIntegration   : CTSettingsIntegration
  ├── markerDetector        : MarkerDetector
  ├── triggerRegistry       : TriggerRegistry
  ├── triggerBuilder        : TriggerBuilder
  ├── triggerExecutor       : TriggerExecutor
  └── notificationHUD       : CTNotificationHUD

Global reference: g_CTCSystem (set via getfenv(0)["g_CTCSystem"]).

Game Hook Pattern

Hook Purpose
Mission00.load Create CustomTriggerCreator instance
Mission00.loadMission00Finished Initialize, register dialogs
FSBaseMission.update Per-frame: marker proximity, UI hints
FSBaseMission.draw HUD rendering
FSBaseMission.delete Cleanup
FSCareerMissionInfo.saveToXMLFile Save trigger data
Mission00.onStartMission Load saved trigger data

Critical Knowledge: GUI System

Coordinate System

  • Bottom-left origin: Y=0 at BOTTOM, increases UP
  • Dialog content: X relative to center (negative=left, positive=right), Y NEGATIVE going down from top
  • All positions in px

Dialog XML Template (Copy TakeLoanDialog.xml structure!)

<GUI onOpen="onOpen" onClose="onClose" onCreate="onCreate">
    <GuiElement profile="newLayer" />
    <Bitmap profile="dialogFullscreenBg" id="dialogBg" />
    <GuiElement profile="dialogBg" id="dialogElement" size="780px 580px">
        <ThreePartBitmap profile="fs25_dialogBgMiddle" />
        <ThreePartBitmap profile="fs25_dialogBgTop" />
        <ThreePartBitmap profile="fs25_dialogBgBottom" />
        <GuiElement profile="fs25_dialogContentContainer">
            <!-- Content goes here -->
        </GuiElement>
        <BoxLayout profile="fs25_dialogButtonBox">
            <Button profile="buttonOK" onClick="onOk"/>
        </BoxLayout>
    </GuiElement>
</GUI>

3-Layer Button Pattern

<Bitmap profile="myButtonBg" id="btn1bg" position="Xpx Ypx"/>
<Button profile="myButtonHit" id="btn1" position="Xpx Ypx" onClick="onClickBtn1" visible="false"/>
<Text profile="myButtonText" id="btn1text" position="Xpx Ypx" text="Click Me"/>

Custom GUI Icons

Set image paths dynamically in Lua onCreate() via setImageFilename(g_currentModDirectory .. "path"). Profile MUST have imageSliceId value="noSlice".

What DOESN'T Work (Lua 5.1 Constraints)

Pattern Problem Solution
goto / labels FS25 = Lua 5.1 Use if/else or early return
continue Not in Lua 5.1 Use guard clauses
os.time() / os.date() Not available Use g_currentMission.time
Slider widgets Unreliable Use MultiTextOption
DialogElement base Deprecated Use MessageDialog pattern
onClose/onOpen callbacks in XML Stack overflow Use different callback names
XML imageFilename for mod images Fails from ZIP Set dynamically via setImageFilename()
MapHotspot base class Abstract, no icon Use PlaceableHotspot.new()
registerActionEvent without RVB wrapper Duplicate keybinds Use full RVB pattern
setTextColorByName() Doesn't exist Use setTextColor(r, g, b, a)
PowerShell Compress-Archive Backslash paths in zip Use bash zip

File Size Rule: 1500 Lines

If any file exceeds 1500 lines, trigger a refactor to break it into smaller focused modules.

No Branding / No Advertising

  • Never add "Generated with Claude Code", "Co-Authored-By: Claude", or any claude.ai links to commit messages, PR descriptions, code comments, or any project artifacts.

Session Reminders

  1. Read this file first before writing code
  2. Check log.txt after changes — look for [CTC] prefixed lines
  3. GUI: Y=0 at BOTTOM, dialog Y is NEGATIVE going down
  4. No sliders — use quick buttons or MultiTextOption
  5. No os.time() — use g_currentMission.time
  6. Copy TakeLoanDialog.xml pattern for new dialogs
  7. FS25 = Lua 5.1 (no goto, no continue)
  8. Images from ZIP: set dynamically via setImageFilename() in Lua
  9. Build with bash build.sh --deploy
  10. MarkerDetector: use distance-squared checks in update() — never math.sqrt
  11. F8 is the default open key (F7 is taken by NPCFavor)
