ZDoom

Added

I have removed all previous file attachments as they are obsolete and do not work. I have added a link to a working example file as of 29/05/2021 that properly demonstrates the new feature

Yes, I am in agreement with new AddDialogues key (that's like AddEventHandlers, right?! =D) and for my project, I will exclusively use AddDialogues instead of Dialogue.

OK, I missed that point indeed.

For compatibility reason GAMEINFO's Dialogue should remain the same.
It should reference only one file and its actual value should depend on loading order.

Additive dialogs can be implemented via separate GAMEINFO key, like AddDialogues for example.
The thing is this approach doesn't work quite well if both definitions are mixed.
Dialogue key overrides the first script while AddDialogues inserts them at the end of the list.

Thanks, this is already a huge improvement, but unfortunately it still does not solve the original concern of stacking multiple NPC mods together... try this load order: BaseGame, UserMod, AnotherMod. The demon and revenant will not talk.

The problem is that it's not possible for a mod to list every mod to be included... AnotherMod doesn't know the existence of UserMod.

[off topic info: in my first post, I erroneously left behind a DIALOGUE lump inside the map WADs which weren't actually meant to be there... that technique is considered obsolete to me ever since the GameInfo method. The map files were from some old files before the GameInfo method existed. I have since removed all DIALOGUE lumps from these 3 new files]

With the ability to use full paths to dialog files I don't think that this is needed.
I attached modified base game and mod .pk3s that utilize this feature to load dialogues from both files.

Currently it's impossible to load multiple script00s from different archives; the last one will always win.

This setup is a replica of my intended idea. BaseGame is my imaginary standalone project, and UserMod is a mod someone would create to add new characters into the game. Load BaseGame and UserMod in that order, and the zombieman will no longer talk.

This severely limits the modding capabilities for my users, as there's simple no way to "plug and play" custom NPCs into their preferred mod setup (let's say users want to load several mods - more than 2 - all containing different new NPCs).
