Hello there,

I am trying to Display a players Display Name instead of manually typing it but keep getting blocked by an error.

This is the dialogue text:
How is [lua(Actor["NPC - Kaya P1"].Display_Name)] doing?

This is the setup of the character in the Actors list:

: Error.JPG (29.85 KiB) Viewed 386 times

But when the game runs I get the error:

Dialogue System: Lua code 'return Actor["NPC - Kaya P1"].Display_Name' threw exception 'Lookup of field 'Display_Name' in the table element failed because the table element itself isn't in the table.'

Hi,

When an actor's name appears in the [] parts of the Lua Actor[] table, the name follows the rules here: Table Indices. It replaces characters such as " " (space) and "-" with underscores ("_").

Try this:

How is [lua(Actor["NPC___Kaya_P1"].Display_Name)] doing?

Side note: For the conversation's primary actor and conversant, instead of the more-complex [lua()] tag above, you can simply use [var=Actor] and [var=Conversant].

Thanks for the quick reply! I am using those quick tags for Actor and Conversant already, but sometimes they reference other NPCs in the game. That did the trick for me.

If I wanted to use something that was in a TextTable is there a Lua function or some documentation for that?

Hi,

In version 2.2.40, there will be a new Lua function named GetTextTableValue("key").

In the meantime, you get can it from the C# method DialogueManager.GetLocalizedText("key").

Note: The current Lua function GetLocalizedText("table", "element", "field") predates text tables. Despite the confusing name, it gets the localized version of a field in an Actor[], Item[], Quest[], or Location[] Lua table.

Ok sounds great, I'll try that out when the update is available. Thanks!

Here's a patch if you'd like early access to that function:
