Skyrim MCM Module

Create and edit MCM Helper configuration files for in-game mod settings menus using Spooky's AutoMod Toolkit.

Prerequisites

Run all commands from the toolkit directory:

bash

cd "<TOOLKIT_PATH>"
# Example: cd "C:\Tools\spookys-automod-toolkit"

Overview

MCM (Mod Configuration Menu) allows mods to have in-game settings menus. This module generates JSON configuration files compatible with MCM Helper.

Common Workflows

Create Basic Mod Settings

bash

# 1. Create the MCM config
dotnet run --project src/SpookysAutomod.Cli -- mcm create "MyMod" "My Awesome Mod" --output "./MCM/config/MyMod/config.json"

# 2. Add an enable toggle
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config/MyMod/config.json" "bEnabled" "Enable Mod" --help-text "Turn the mod on or off"

# 3. Add a debug toggle
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config/MyMod/config.json" "bDebugMode" "Debug Mode" --help-text "Show debug messages"

# 4. Add a damage multiplier slider
dotnet run --project src/SpookysAutomod.Cli -- mcm add-slider "./MCM/config/MyMod/config.json" "fDamageMultiplier" "Damage Multiplier" --min 0.5 --max 3.0 --step 0.1

# 5. Validate the configuration
dotnet run --project src/SpookysAutomod.Cli -- mcm validate "./MCM/config/MyMod/config.json"

Create Multi-Page Settings

bash

# Create config
dotnet run --project src/SpookysAutomod.Cli -- mcm create "MyMod" "My Mod" --output "./MCM/config.json"

# Add controls to "General" page (default)
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config.json" "bEnabled" "Enable Mod"

# Add controls to "Combat" page
dotnet run --project src/SpookysAutomod.Cli -- mcm add-slider "./MCM/config.json" "fDamage" "Damage Bonus" --min 0 --max 100 --page "Combat"
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config.json" "bCritical" "Enable Criticals" --page "Combat"

# Add controls to "Magic" page
dotnet run --project src/SpookysAutomod.Cli -- mcm add-slider "./MCM/config.json" "fSpellCost" "Spell Cost Reduction" --min 0 --max 50 --page "Magic"

Validate and Check Existing MCM

bash

# Check MCM structure
dotnet run --project src/SpookysAutomod.Cli -- mcm info "./MCM/config/SomeMod/config.json"

# Validate for errors
dotnet run --project src/SpookysAutomod.Cli -- mcm validate "./MCM/config/SomeMod/config.json"

MCM Helper Integration

Required File Structure

MCM Helper expects files in specific locations:

code

Data/
  MCM/
    config/
      MyMod/
        config.json     # Main config (required)
        settings.ini    # Default values (optional)
    translations/
      MyMod_english.txt # Translations (optional)

Config JSON Format

Generated config.json structure:

json

{
  "modName": "MyMod",
  "displayName": "My Awesome Mod",
  "minMcmVersion": 7,
  "pages": [
    {
      "pageDisplayName": "Main",
      "content": [
        {
          "type": "toggle",
          "id": "bEnabled",
          "text": "Enable Mod"
        },
        {
          "type": "slider",
          "id": "fDamage",
          "text": "Damage Multiplier",
          "min": 0.5,
          "max": 2.0,
          "step": 0.1
        }
      ]
    }
  ]
}

Control Types

Type	Description	Properties
toggle	Checkbox	id, text, help
slider	Value slider	id, text, min, max, step
dropdown	Dropdown list	id, text, options
keymap	Key binding	id, text
text	Text input	id, text

Linking MCM to Scripts

MCM values are stored as GlobalVariables in your plugin:

papyrus

ScriptName MyMod_ConfigScript extends Quest

; These must match the MCM control IDs
GlobalVariable Property bEnabled Auto
GlobalVariable Property fDamageMultiplier Auto

Function ApplySettings()
    If bEnabled.GetValue() == 1
        float damage = fDamageMultiplier.GetValue()
        ; Apply settings...
    EndIf
EndFunction

Naming Conventions

Control IDs

Follow Hungarian notation for clarity:

•bSomething - Boolean toggles
•fSomething - Float sliders
•iSomething - Integer values
•sSomething - String values

Examples

•bEnabled - Main enable toggle
•bDebugMode - Debug mode toggle
•fDamageMultiplier - Damage multiplier (float)
•iItemCount - Item count (integer)
•fSpellCostReduction - Spell cost reduction percentage

Important Notes

•MCM Helper required - Users must have MCM Helper installed
•GlobalVariables must exist - Create matching globals in your plugin
•File location matters - Place config in Data/MCM/config/ModName/
•Validate before release - Always run validate command
•Use --json flag for machine-readable output when scripting

Complete MCM + Plugin Workflow (Basic)

bash

# 1. Create the plugin
dotnet run --project src/SpookysAutomod.Cli -- esp create "MyConfigMod.esp" --light

# 2. Add globals that match MCM controls
dotnet run --project src/SpookysAutomod.Cli -- esp add-global "MyConfigMod.esp" "bEnabled" --type long --value 1
dotnet run --project src/SpookysAutomod.Cli -- esp add-global "MyConfigMod.esp" "fDamageMultiplier" --type float --value 1.0

# 3. Create MCM config
dotnet run --project src/SpookysAutomod.Cli -- mcm create "MyConfigMod" "My Config Mod" --output "./MCM/config/MyConfigMod/config.json"

# 4. Add matching controls
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config/MyConfigMod/config.json" "bEnabled" "Enable Mod"
dotnet run --project src/SpookysAutomod.Cli -- mcm add-slider "./MCM/config/MyConfigMod/config.json" "fDamageMultiplier" "Damage Multiplier" --min 0.5 --max 2.0 --step 0.1

# 5. Validate
dotnet run --project src/SpookysAutomod.Cli -- mcm validate "./MCM/config/MyConfigMod/config.json"

Complete MCM + Script Workflow with Auto-Fill

bash

# 1. Create the plugin and quest
dotnet run --project src/SpookysAutomod.Cli -- esp create "MyConfigMod.esp" --light
dotnet run --project src/SpookysAutomod.Cli -- esp add-quest "MyConfigMod.esp" "MyConfigQuest" --start-enabled

# 2. Add globals that match MCM controls
dotnet run --project src/SpookysAutomod.Cli -- esp add-global "MyConfigMod.esp" "bEnabled" --type long --value 1
dotnet run --project src/SpookysAutomod.Cli -- esp add-global "MyConfigMod.esp" "fDamageMultiplier" --type float --value 1.0
dotnet run --project src/SpookysAutomod.Cli -- esp add-global "MyConfigMod.esp" "bDebugMode" --type long --value 0

# 3. Create script that references these globals
cat > "./Scripts/Source/MyConfigScript.psc" << 'EOF'
ScriptName MyConfigScript extends Quest

GlobalVariable Property bEnabled Auto
GlobalVariable Property fDamageMultiplier Auto
GlobalVariable Property bDebugMode Auto

Event OnInit()
    RegisterForSingleUpdate(1.0)
EndEvent

Event OnUpdate()
    If bEnabled.GetValue() == 1
        float mult = fDamageMultiplier.GetValue()
        If bDebugMode.GetValue() == 1
            Debug.Notification("Damage multiplier: " + mult)
        EndIf
    EndIf
    RegisterForSingleUpdate(5.0)
EndEvent
EOF

# 4. Compile script
dotnet run --project src/SpookysAutomod.Cli -- papyrus compile "./Scripts/Source/MyConfigScript.psc" --output "./Scripts" --headers "./skyrim-script-headers"

# 5. Attach script to quest
dotnet run --project src/SpookysAutomod.Cli -- esp attach-script "MyConfigMod.esp" --quest "MyConfigQuest" --script "MyConfigScript"

# 6. Auto-fill script properties from PSC (links globals automatically!)
dotnet run --project src/SpookysAutomod.Cli -- esp auto-fill "MyConfigMod.esp" --quest "MyConfigQuest" --script "MyConfigScript" --psc-file "./Scripts/Source/MyConfigScript.psc" --data-folder "C:/Skyrim/Data"

# Output:
# Filled property 'bEnabled' with MyConfigMod.esp:0x000800
# Filled property 'fDamageMultiplier' with MyConfigMod.esp:0x000801
# Filled property 'bDebugMode' with MyConfigMod.esp:0x000802

# 7. Create MCM config
dotnet run --project src/SpookysAutomod.Cli -- mcm create "MyConfigMod" "My Config Mod" --output "./MCM/config/MyConfigMod/config.json"

# 8. Add matching MCM controls
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config/MyConfigMod/config.json" "bEnabled" "Enable Mod"
dotnet run --project src/SpookysAutomod.Cli -- mcm add-slider "./MCM/config/MyConfigMod/config.json" "fDamageMultiplier" "Damage Multiplier" --min 0.5 --max 2.0 --step 0.1
dotnet run --project src/SpookysAutomod.Cli -- mcm add-toggle "./MCM/config/MyConfigMod/config.json" "bDebugMode" "Debug Mode"

# 9. Validate MCM
dotnet run --project src/SpookysAutomod.Cli -- mcm validate "./MCM/config/MyConfigMod/config.json"

# 10. Generate SEQ file (required for start-enabled quest)
dotnet run --project src/SpookysAutomod.Cli -- esp generate-seq "MyConfigMod.esp" --output "./SEQ"

Why This Workflow Matters:

•Auto-fill automatically links the GlobalVariable properties in your script to the actual globals in your plugin
•No manual property filling in Creation Kit required
•Type-safe matching ensures correct globals are linked
•Works with your own plugin's globals, not just vanilla Skyrim records

JSON Output

All commands support --json for structured output:

bash

dotnet run --project src/SpookysAutomod.Cli -- mcm info "./config.json" --json
