See "Script Help" -thread.When you look in Advance Map in the Pallet Town map, you see Prof Oak standing right next to your house. But if you play the game he becomes invisible and you can walk right through the spot where he is supposed to stand. He will stay this way untill you reach the grass where he stops you. How do I make a sprite invisible untill a kind-of-alike script is activated?
To have person event's flag bit as 1 (=set) before you "encounter" it in the game, you've to set it in another event that occurs before that.
If there is no "mandatory" event before that happening, you've to set it through map's Script Header.
(Proper way would be doing it through assembly that's gone through in the intro but that's not required so...)
