Match Node
A Match Node is useful for selecting the next Node based on the well-known value of a variable or expression.
They have the following characteristics:
Description
A human-readable description of the match Node to aid future understanding of the Node at a quick glance.
Fact
The Fact to evaluate for the match Node. These are stored in the Fact Store and determine the available cases that can be used to select against.
Cases
The values that are selected against. For example, if a Fact evaluates to a
values of WAVE and there is a case called WAVE, then these will match. If a
Node a Node is connected to this case, then this will be next Node that is
processed as part of the Dialogue Sequence.
Parley also supports a fallback case for when nothing is matched. This is useful to ensure the dialogue can continue in these cases. However, it is optional as one might not want a fallback case in these situations.
