Papyrus is now crying...but with NEW CUSTOM ATTACKS ! NYEH HEH HEH ! "DEAR HUMANS, THANK YOU FOR THE 2,244 VIEWS ! I'M NOW POPULAR ! NYEH HEH HEH !" I've made a tutorial in my script for making custom attacks. To see it, go inside my project (Disblief Papyrus), go to the "g_monster" sprite, SCROLL on the top-right of the script, then search for a comment that says "PART 1 OF MAKING CUSTOM ATTACKS". Hope that helps you and that you find/understand it !
Please note it's a remixed project, from Undertale Simple Battle Creator. Undertale is from Toby Fox (warning spoilers...?) Nearly all attacks are made by me ! It took me 10 hours to remix it. Hope you like it !
