Nodes

A Dialogue is composed of nodes displayed from top to bottom, and can even be set as children of other nodes.

Dialogue Nodes Layout

Nodes can be dragged and dropped to change their position in the conversation tree. Dragging and dropping onto another node, will convert the dragged one into a child of the targeted.

There are three different node types: Text, Choices and Random nodes.

Text

Text nodes are the most common and used to display conversations. They display a text message on screen and simply jump to the next node when they are finished.

Dialogue Nodes Text

Using child nodes of Text

It's important to note that a Text node can contain children nodes. These will be executed if, and only if, the parent Text node's conditions are satisfied. This is specially useful if you want to display a conversation only after meeting certain conditions.

Any text can be enhanced with rich text tags, which allow to change the color, size and other properties of specific regions. For example, to display the word James in white in the phrase Hello James, you can surround the specified word between <color> tag:

Hello <color=#FFFFFF>James</color>

Choices

Choice nodes prompt the user with a collection of choices. How these choices are presented and their behavior is configured below with a new set of fields that appear.

The available choices are picked from the direct children of the Choices node, which should usually be Text nodes.

Dialogue Nodes Choices

  • Hide Unavailable: Determines whether unavailable choices (their Conditions return false) should be displayed (but greyed out) or hide them completely.
  • Hide Visited: Determines whether the choice is skipped if the line has already been visited.
  • Skip Choice: Allows to skip the execution of the Text choice selected, and skip to the next immediate one.
  • Shuffle Choices: When ticked, the choices order will be shuffled and displayed randomly.
  • Timed Choice: Determines if the choice has a time limit. If checked, two new fields wil appear down below.
    • Duration: Specifies the amount of time the user has to pick a choice, in seconds.
    • Timeout: Defines what happens if the user fails to input a choice, which can either be picking one at random, the first option or the last one (both prior to shuffling, if enabled)

Skipping Choices

Choosing Skip Choice allows the player to not speak the dialogue line when picking it from the prompt. For example, let's say a bartender asks the player whether they want a drink. The Player could see the option "Yes, a Moonlight Specter". If left unchecked, the Player would then execute the Text node. Some games, however, don't repeat the choice made by the user and assume the player already said it when the user picked the choice.

Single Choice

If the Choices does only have a single choice available, it will be automatically selected without requiring the user to choose it.

Random

Random picks are similar to Choices, except for the fact that the user is not prompted to pick them, and instead, they are randomly picked.

Dialogue Nodes Random

The Random node also has the field Allow Repeat which determines whether the same choice can be picked in a row, or not.

Greeting

Random choices are useful to allow characters to pick a random line from a collection. For example, a shop keeper could greet the player differently every time they talk.
