Dialogue line ID

SetText commands often uses the same format for specifying a dialogue line id from the current map or from CommonDialogue which is an int value. This is done by a method called GetDialogueText:

public static string GetDialogueText(int id)

It resolves a dialogue line id of id where the format is detailed in this page.

Current map line id

Any value >= 0 is considered a current map line id. This means that it will check the current map, resolve its enum value name and pick the file of the same name inside the maps folder of the current language's dialogue folder. The value directly corresponds to a line index starting from 0. If no such line exists, an exception will be thrown.

CommonDialogue line id

To refer to a CommonDialogue line id instead of a current map line id, the value must be specified in the form -id - 1. Any value below 0 will be interpreted as a CommonDialogue line id with the id being the absolute version of the value - 1. For example, -1 refers to CommonDialogue line 0. The file is always the one named CommonDialogue located at the root of the current language's dialogue folder. If no such line exists, an exception will be thrown.

What about MenuText?

It's possible to use another method to get MenuText lines:

private static string GetText(bool menu, int id)

It returns GetDialogueText(id) if menu is false (so a regular dialogue line id) or menutext[id] if menu is true.

To use menu text with commands, it must be done, using a menu or prompt command which supports specifying one.
