Event hooks for modifying Lua state before evaluating conditions.

[ashapcott]

Hi, sorry if this has been answered elsewhere but I haven't had much luck finding an answer.

I'm looking for a way to modify the Lua state in C# before the conditional script on a DialogueEntry is evaluated. I need to do so before evaluating each entry's conditions to allow for setting up my own Lua variables. As far as I can tell this would require some kind of message to be sent during ConversationModel.EvaluateLinksAtPriority but I wasn't able to find one. Is there a way to do this that I'm missing?

For details on my specific use case: I have conversations that use a field to specify that they belong to a particular questline (note that I'm not using the built-in quest system, but I don't think that matters). When entries are evaluated in the conversation, I use the OnPrepareConversationLine message to set a global variable "quest" in the current Lua state based on this field. This improves brevity when writing Lua scripts for entries. However, this doesn't work for conditional scripts.

Hi,

You should be able to use OnPrepareConversationLine().

Say dialogue entry A links to entries B, C, and D. When the Dialogue System prepares entry A, it calls OnPrepareConversationLine(A) before running EvaluateLinks to determine which of B, C, and D are currently valid.
