I'm using the "On Use" command trigger to start a conversation with a 2D NPC but it doesn't work (it works with "On Start").

I'll explain the steps I made:
- I Imported the DialogueManager and created a DialogueDatabase and setted it as Reference database
- I Created my conversation
- I Created an NPC and a Player
- The Player has the selector component (I increased the distance for the selection just in case); the NPC has a Sprite Renderer, a Box collider set on "Is Trigger"; a Dialogue System Trigger set on "On Use" with the right Dialogue Database Reference and the Action to start the right conversation; and an Usable component (Max distance 30).

I have enabled the 2D Physics just in case, but doesn't change anything, I can't select the NPC to start the conversation, and the Selector does not display anything if the mouse position is on the NPC box collider.

Here the scene:

I'm using Unity 2020 LTS, but I tried 2019 LTS with the same result.


Second question: Is it possible to read a variable from the database and change its value from a C# script like you do with the animator variables? Is there a tutorial or an example for this?

Thank you in advance for the help.

Hi,

Open the Dialogue System's Welcome Window (menu item Tools > Pixel Crushers > Dialogue System > Welcome Window) and double-check that the USE_PHYSICS2D checkbox is still ticked.

Then inspect the player's Selector component and set "Run Raycasts" to "In 2D".

Use Physics2D was checked, the problem was the Run Raycasts set in 3D. Thanks for the help

About the variables? Is there a simple way to read and write the variables you create in the dialogue database with a C# script?

Sorry, I forgot to answer that. Yes. Use DialogueLua.GetVariable() and SetVariable(). Example:
