These scripts are used for triggering effects, dialog, text, and audio files. These scripts can be altered. Basically changing SSNs and Groups can produce different results in the scripts. To use these scripts, copy and paste the script that you want into the wac file and change the scripts to suit your needs.
These scripts can be interchanged and placed together. For example, you can put a wav file with a text command, wav files with mortar hits, etc......
