4.1 Starting a Dialog

Start Dialog

Image	Info
	Initiates a dialog sequence using the specified dialog tree asset and configuration.
Description
To start a Dialog, add the Start Dialog Node. This Node interacts with the BDC_DialogBackend_Subsystem to run a specific Dialog Tree. Starting a Dialog will call the Dispatchers for OnDialogStarted on all Participant Components used in this Dialog, the Manager Component, and OnDialogStartedGlobal of the Subsystem itself. It also triggers the OnDialogStarted Interface Event for the used Widget. While starting a Front or Back Dialog, the System will spawn the corresponding Dialog Widget from the Class you setup in the project Settings. This Widget then is added to the GameClientViewport, which makes the Dialog persistent, even while switching levels. This is differently handled for Bubble Dialogs. Those will be started on their own separate Task and run in the background, allowing for the Player to run around, talk to NPCs - But have other NPCs chat simultaneously.
