Question

一切正常，但是我无法使程序打印（“完全向后”）和打印（“完全向右”）。我很确定我的值在if语句中是正确的。

我还有另一个程序，可以显示模拟摇杆的位置值和正确的值。我试图切换大于/小于大于的语句，但是什么也没做，我已经仔细检查了值。

        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，只是不打印任何内容，我也不知道为什么，我希望它可以完全正确打印或完全反向打印。

我修改了代码中的条件语句，以添加“死区”和“边缘区”的概念。您可以将“死区”视为内半径，将在其中记录为“居中”的运动，而在较大外半径之外（即在边缘区域中）的运动是沿固定方向的运动。该代码可能是这样的：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空间：

import pygame

pygame.init()

"""
Just a check to ensure a joystick is plugged in.
Only going to retrieve data for the 0th joystick anyways...
"""
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

while True:
    for event in pygame.event.get():
        pass

    """

    if (-dead_zone < left_x < dead_zone) and (-dead_zone < left_y < dead_zone):
