改了移动速度，移动的时候事件图会偏移一个像素点 - Project1

##------
## Display rounding error fix created by Neon Black.
##
## When certain slow display panning speeds are used, events will improperly
## round floating values to determine their position on screen. This causes
## them to appear off from the tilemap by a single pixel. Though minor this is
## noticable. This snippet fixes this behaviour.
##
## This snippet may be used in any project.

class Game_Map ## Rounds X and Y display values DOWN so the nearest 32 is found.

def adjust_x(x)
if loop_horizontal? && x < display_x - (width - screen_tile_x) / 2
x - display_x + @map.width
else
x - display_x
end
end
def adjust_y(y)
if loop_vertical? && y < display_y - (height - screen_tile_y) / 2
y - display_y + @map.height
else
y - display_y
end
