The yarnspin compiler is just the yarnspin.exe in the root of the folder. It will compile all the files in the scripts folder, create the yarnspin.dat, and run the game.
Okay, thank you. I really appreciate your help.
Running yarnspin.exe from the command line interface gives the following error "No yarnspin.dat game data can be loaded."
Here's the script I made...
title: My First Yarn
author: Your Name
start: my_location
=== my_location ===
img: room.png
txt: You are standing in a small room. There is a person here, it's Carol.
opt: Talk to Carol
act: my_dialog
=== carol ===
name: Carol the Neighbor
short: Carol
face: carol.png
=== my_dialog ===
carol: Hello! Welcome to my humble abode.
player: Hi. Thanks for having me.
say: Say goodbye and leave.
act: end_conversation
=== end_conversation ===
carol: Goodbye! Have a great day!
act: my_location
