## The ID of the terrain used to display the large character above ☆ tiles.
## If the player is below this tile (y position), the sprite will appear
## above all tiles and events from that y position up. If the player is on
## the same tile or above (y position) the event will appear BELOW ☆ tiles
## from that position up.

## This value is the pixel tuning used to check the location. This is
## because characters tagged with a '!' in their name are drawn lower than
## normal characters and are considered to be lower than these. This causes
## the script to think they are on the tile below where they really are and
## draw them above tiles they should appear under.
