<icon_index: x>For some icon index x.If you have never used the Note Manager before, first paste the script into your project, and then test play the game. You should see a new Notes folder inside your data folder.
To check which note file you need to edit, you will need three things
-the map ID
-the event ID
-the page number
Then go into the following folder: Data -> Notes -> Maps -> map_ID
Look for the file named event(ID)_page(ID).txt, and that's where you would add it.
