I've poured over the entire script for Pokemon Essentials, and I can't figure out where I can change this, so can someone help me out?
I want to know where the default ME or SE is set up for things like obtaining items, obtaining a pokemon, leveling up, etc. I know the easiest way is probably to change the filename, but I'd rather know where the default script is located so I can also add on my own ME like when a Pokemon is purified or something like that.
The ME Sounds are located in the scripts itself, e.g the Sound for obtaining an item is located in the item scripts. The best way to find a particular sound is to simply search for the file name in the script editor. Open the script Editor in the RPG Maker and press CTRL + Shift + F to search in all areas. Type in the file name and click search. You'll propably find multiple entries, because some of the files are used in several cases. The best indicator for the seeked code is imo the message-part that's assigned to it (e.g "Player found the item X").
