Memory-Aware Dialog System MZ (Witcher/Skyrim-style)

Description

This is an RPG Maker MZ plugin that allows you to track which dialog options the player has already selected in Show Choices command, and marks them visually with a different text color. It's similar to how RPGs like Witcher or Skyrim handle visited dialog: once you choose an option, it becomes "greyed out" (or any other color) the next time that dialog is shown.

Features

• Tracks selected dialog options per map, event, and dialog ID.
• Once selected, a choice line is recolored (you choose the colors)
• No switches or variables needed: the plugin uses self switches internally
• Includes a global utility function to check dialog state from anywhere
• Tag any dialog choice in game with <Seen: dialog_id>

Example (Show Choices event command):

• <Seen: intro> Who are you?
• <Seen: ruins> Ask about the ruins
• Goodbye.

Selecting the first or second choice will mark them as 'visited', and they will be re-colored the next time you visit the dialog choices.


To check if a dialog has been visited, the plugin provides a global function calledJavaScript:

$isDialogVisited(mapId, eventId, dialogId)

This is so you can use them in conditional branches, e.g:
JavaScript:

if ($isDialogVisited(5, 3, "ruins")) { // Do stuff }

You can also use the short-hand (if used within the same event):

$isDialogVisited("ruins") // This will auto-resolve to: $isDialogVisited($gameMap.mapId(), this.eventId(), "ruins")

Manual and Auto-Marking
By default, tagging a choice with <Seen: dialog_id> will automatically mark it as visited upon selecting the dialog. But sometimes, you may not want that.

The plugin also introduces a <$Seen: dialog_id> (with a '$' at the start). This will ensure that the dialog is NOT marked as visited automatically upon selection (but still shows the correct color). You have to manually mark it later, using:
JavaScript:

$setDialogVisited(5, 3, "ruins") // Same as before, you can also use the short-hand (within the same event): $setDialogVisited("ruins")

Reset Marking
You can also reset a dialog to its original state using:

$resetDialogVisited(5, 3, "ruins") // Or from the same event: $resetDialogVisited("ruins")

Plugin Commands

For your convenience, two plugin commands are also provided:

• Set Dialog as Visited - remotely sets the "visited" flag for any dialog option
• Clear Dialog Visited Flag - remotely clears the "visited" flag for any dialog option

Compatibility

• Works well on the MZ engine and also with VisuStella plugins.
• Has not been tested with other plugins
• Has not been tested on MV, but it should work (except for plugin commands)

AI Disclaimer
This plugin was created by me without the use of AI tools. I am using it in my own game. AI was only used to write documentation and JS Doc comments in a clean and readable manner.

FAQ
Q: Why isn’t my dialog being tracked?
A: Make sure the <Seen: dialog_id> tag is present in the choice text and that dialog_id is a valid one-word string or number with no spaces or punctuations.

Q: How do I manually mark a dialog as visited?
A: Use <$Seen: dialog_id> to disable auto-marking. Then use $setDialogVisited(mapId, eventId, "dialog_id") in a script whenever you want to mark it.

Q: I want to use normal game switches (e.g. 101, 112, 312, etc.) to track dialog choices. Can I use it?
A: Yes, the plugin supports it. But please read the help file carefully and only do it if you fully understand the risks.
