Put this in a script cause you only need it to run once. Right above main should work.
class Game_Event
attr_accessor:character_name
attr_accessor:pattern
end
Change graphics
a="001-Fighter01"
$game_map.events[1].character_name=a
Change pattern
$game_map.events[1].pattern = 3
You need to change both the 1's to the correct ID. It now sets the pattern to far right. Far left is 0, middle left is 1 and middle right is 2.
If you want something else than the top row, you need to add this:
$game_map.events[1].direction = 2
2 - First row. 4 - Second row. 6 - Third row. 8 - Bottom row.
