Config

When a game starts, it will load a config file named “.1-o-flappy” that be at your home directory. If that file does not exist, the game will create it. If you want to see the default content of this file, please go to next page.
The file must contain these to run the game normally:

roll_skin -> a str
width -> an int(> 0)
p_skin -> a str
height -> an int(> 0)
blank_skin -> a str
speed_v -> an int or a float(> 0) or a str(eval(str) > 0)
v_border -> a str
speed_h -> an int or a float(> 0) or a str(eval(str) > 0)
h_border -> a str
high -> an int(> 0)
roll_range -> an int(> 0) or a str(type(eval(str)) == int and eval(str) > 0)
cooldown_tile -> an int(>= 0) or a str(type(eval(str)) == int and eval(str) >= 0)

roll_skin means the skin of the rolls(the default is "|").
p_skin means the skin of the “bird”(the default is "O").
blank_skin means the skin of the blank area(the default is " ").
v_border means the skin of the vertical border on the right(the default is "").
h_border means the skin of the horizontal border on the bottom(the default is "-").
You can color the skin(like "\033[42m").
The default content of the config file:

# The config file of Flappy.

# Skin config start
roll_skin = "|"
p_skin = "O"
blank_skin = " "
v_border = ""
h_border = "-"
# Skin config end

# Gameplay config start
width = 79
height = 18
speed_v = 20
speed_h = 4
roll_range = 3
cooldown_tile = 16
high = 15
# Gameplay config end

width means the visible width of the checkerboard(the default is 79).
height means the visible height of the checkerboard(the default is 18).
speed_v means the vertical(right to left) moving speed of the “bird”(the default is 20). It is also the speed of the refreshing.
speed_h means the horizontal moving speed of the “bird”(the default is 4).
roll_range means the passable range of the rolls(the default is 3).
cooldown_tile means the value of the least separation of two rolls(the default is 16).
high means the initial height of the “bird”.
speed_v, speed_h, roll_range, cooldown_tile can be a str. If it is a str, the game will read it as eval(str). Be sure the eval value of it is a positive, and also be sure the type of the eval value of roll_range or cooldown_tile is an int. Else an error will occur.
Some usable values:

"(time.time()-start_time)" # the value of the time that game has run(Unit: s)
"(score)" # the score of the game
"(high)" # the height of the "bird"
"(time.time())" # the time that be generated by time.time
"(sum(checkerboard))" # the sum of the height of all the rolls
