No no, there are variables you have to change in the default scripts.
And usualy, people who post in RGSS support post here because they want to resolve the problem themselves
You might want to change this in Game_Player
CENTER_X = (544 / 2 - 16) * 8 # Screen center X coordinate * 8
CENTER_Y = (416 / 2 - 16) * 8 # Screen center Y coordinate * 8
and hange a couple of things in setup_scroll, from Game_Map
def setup_scroll
@scroll_direction = 2
@scroll_rest = 0
@scroll_speed = 4
@margin_x = (width - 17) * 256 / 2 # Screen non-display width /2
@margin_y = (height - 13) * 256 / 2 # Screen non-display height /2
end
