RunOptionsAsync(DialogueOption[],CancellationToken)

Method in DialogueViewBase

Summary

Called by the DialogueRunner to signal that a set of options should be displayed to the user.

public override async YarnTask<DialogueOption?> RunOptionsAsync(DialogueOption[] dialogueOptions, CancellationToken cancellationToken)

Remarks

This method is called when the Dialogue Runner wants to show a collection of options that the user should choose from. Each option is represented by a DialogueOption object, which contains information about the option.

When this method is called, the Dialogue Presenter should display appropriate user interface elements that let the user choose among the options.

This method should await until an option is selected, and then return the selected option. If this view doesn't handle options, or is otherwise unable to select an option, it should return YarnAsync.NoOptionSelected. The dialogue runner will wait for all dialogue views to return, so if a dialogue presenter doesn't or can't handle options, it's good practice to return as soon as possible.

If the cancellationToken becomes cancelled, this means that the dialogue runner no longer needs this Dialogue presenter to make a selection, and this method should return as soon as possible; its return value will not be used.

The default implementation of this method returns YarnAsync.NoOptionSelected.

Parameters

Name	Description
Yarn.Unity.DialogueOption[] dialogueOptions	The set of options that should be displayed to the user.
CancellationToken cancellationToken	A System.Threading.CancellationToken that becomes cancelled when the dialogue runner no longer needs this dialogue presenter to return an option.

Returns

A task that indicates which option was selected, or that this dialogue presenter did not select an option.
