So I created a movement/battle script where the trainer and an NPC both move. The player movements work just fine but the NPC stands in place and then doesn't disappear when the battle is over. I've created similar scripts in the past and I'm very stumped. I'm hoping someone may be able to help me. I can post or PM the script if necessary. Thank you.
If you did not expand the amount of flags it can lead to completely random results, as is also stated in this thread: https://www.pokecommunity.com/showthread.php?t=302347. Long story short: no, it's not safe to use them, so you shouldn't. Instead, stay with the flags mentioned in the sources I sent before.
That's why I was curious what sources you used. Because anything I've ever read about flags is to be cautious which ones to use.
Either way, you use hidesprite 0x11. So that means person event number 17 (in decimal) will be hidden. Make sure those correspondent correctly with AdvanceMap. Subsequently, make sure to use a safe flag instead of those you've used up to this point.
I'll definitely make sure to use safe flags from here on out. This specific script is actually for the end of the game so I'm surprised I haven't encountered a single glitch in 10+ playtests. I appreciate the help, thank you so much!
