Editing How can I conditionalize dialogue on the sum of two variables, or compare one variable against another?

A dialog topic can check to see if a variable against a static number, but not the sum of multiple variables.


In these cases you could create a variable to hold that relationship, and set it in the results of a parent topic leading to choices conditionalized on that variable.


Example 1: if you want to conditionalize a topic for X + Y < 10:

*Create a variable on the NPC called XY (you could also use a quest variable or a global variable)

*Create a parent topic ParentTopic "Hire Mercenaries"

*In that topics results: set XY to X + Y

*Create one or more choices off of ParentTopic, e.g. HireMerc1, HireMerc2

*The conditions on HireMerc1 and HireMerc2 can now use the condition: GetScriptVariable theNPCID, XY < 10


Example 2: if you want to conditionalize a topic for X < Y:

*Create a variable named XlessthanY

*In the parent topic's results: use an if statement and set it to be 0 or 1

*Check XlessthanY in the conditions on the dialogue choices linked to the parent topic.
