无法让打印语句工作 PS4 模拟棒

Question

一切正常，但我无法让程序打印（'完全向后'）和打印（“完全正确”）。我很确定我的值在 if 语句中是正确的。

我有另一个程序可以显示模拟摇杆所在位置的值并且我的值是正确的。我试过切换大于/小于语句，但什么也没做，我仔细检查了这些值。

        joystick = pygame.joystick.Joystick(i)###########
        joystick.init()

        for i in range( 0, 2 ):
            axis = joystick.get_axis( i )
            #print('Axis {} value: {:>6.3f}'.format(i, axis))
            axis0 = joystick.get_axis(0)
            axis1 = joystick.get_axis(1)
            #backward totally
            if axis1 == 1.000:
                print("backward totally")
            #Nothing GOOD
            if -.100 < axis0 < .100 and -.100 < axis1 < .100:
                print('centered')
            #forward totally GOOD
            if axis1 == -1.000:
                print('forward totally')

            #left totally GOOD
            if axis0 == -1.000 and -.599 < axis1 < 0.200:
                print("left totally")
            #right totallly 
            if axis0 == 1.000 and -.599 < axis1 < 0.200:
                print('Right totally')

它不会给出错误它只是不打印任何东西，我不知道为什么，我希望它完全正确或完全向后打印。

我修改了代码中的条件语句，添加了“死区”和“边缘区”的概念。您可以将“死区”视为一个内半径，在该内半径内，运动被记录为“居中”，而在较大外半径之外（即在边缘区域）的运动是在一个承诺方向上的运动。这是该代码的样子；考虑到我的 xbox 360 控制器的布局，每个摇杆的复制肯定有改进的余地：

import pygame

pygame.init()

"""
Just a check to ensure a joystick is plugged in.

"""
num_joysticks = pygame.joystick.get_count()
if num_joysticks == 0:
    raise ValueError("No joysticks attached!")

joystick = pygame.joystick.Joystick(0)
joystick.init()

#Just some info about the controller
j_id = joystick.get_id()
j_name = joystick.get_name()
num_axes = joystick.get_numaxes()
num_balls = joystick.get_numballs()
num_buttons = joystick.get_numbuttons()
num_hats = joystick.get_numhats()
print(j_id, j_name)
print(num_axes, num_balls, num_buttons, num_hats)

#Define the inner and outer radii that are considered 0 and 100% movement
dead_zone = 0.2#inner radius
edge_zone = 0.9#outer radius
