okay, i was sure it was more noticable than this:
Spoiler: noticable? red circle! show There are three ways to have the player not show up:
1) move the wall priority up. tried this, and apparently i ran into the same problem of the part of the wall being darker than the rest of it
2) make it a normal wall, and change the character's opacity to 0 when you want him in the wall. this doesn't work, though, cuz he disappears either a bit after he's in the wall or a bit before
3) make the wall not on a regular layer, but as an event. this is what i did, and you can see a tad of discoloration in that part of the wall now. like i said, it was more obvious before, but apparently it's not that bad now, so my friend (i'm making this for a friend's birthday) might not even notice it, but the ocd-person in me wouldn't like leaving it that way
(three edits to the last post, by the way. just in case you didn't see it)
