Option node

This node defines a list of dialog options that the player has to choose in order to continue the dialog.

Blocks

You can add as many "blocks" as you want in this node using a + button.
You can remove a block by clicking its - button.
If their number grows too big, you can hide each block by clicking the according H button.

Option block

An option is defined by its label. If this option is chosen by the player, the exact same line will be said by the actor.

Not said options

It is possible to define option(s) that will not be said after the player choosed it. If the "Choice only, not said" checkbox is checked, then the actor will not say it. Instead, the tree will directly execute the next node.

Thus, you can define an Action Line node as the next node of an option that's "Choice only, not said". This way, the line actually said by the player will be different from the option line. This Action Line node can even concern another actor than the player, if you wish.

Conditional option

A specific option can be displayed if and only if a certain condition is valid. If the "condition" textbox is filled with a valid statement, then the option will be available for choosing. By default the statement is empty, thus the condition is always true and the option is therefore always available.
