Need Explanation for Macros (Harlowe)

[Kiralios]

Hai I refer to this: https://github.com/daterre/Cradle#runtime-macros

I would like to have two Avatars changing direct speak during ONE passage. I thought I could work with Macros. So that i can invoke a function after some text in a passage, which changes direct speak to another.

So I tried simple Macros but if I have a Macro in my twine.html - file, it wont change to a C# if I import the Twine Story to Unity.

Can someone help me out?

Best
