Title: Get File Name By Loop
Post by: amaranth on February 13, 2013, 12:03:44 AM

This script returns the names of all files in a Resource Folder. You need to set this script up as a loop to extract each file name. I've attached a sample. Fields are:

• Folder Name: enter the path where files are located inside the Resources directory. Leave this field empty to get all files in the Resource folder. Example usage: Creatures/Monsters/Ghosts
• File Name: returns name of the next file in the directory.
• Loop Event: A file was found. Do something and return to the loop.
• No Hit Event: No files were found in directory. Exit loop early.
• Finished Event: The Loop Event has been called for all files in the loop. Exit the loop.

This script is based on Jean's Get Next Ray Cast All Hit script.
