PyGame - 带有 ps3 控制器的 RaspberryPi 3b+
PyGame - RaspberryPi 3b+ with a ps3 controller
我正在尝试将 pygame 与 raspberry pi 结合使用,以将 PlayStation 3 控制器用作汽车的输入。
我已经用演示代码测试了控制器,一切正常。然后,当我尝试在我的程序中使用它时,当操纵杆移动时,它读取 0.0 作为输入。附件是我当前的代码:
import pygame
class controller:
def __init__(self):
pygame.init()
pygame.joystick.init()
global joystick
joystick = pygame.joystick.Joystick(0)
joystick.init()
def get_value(self, axis):
value = joystick.get_axis(axis)
return value
control = controller()
val = control.get_value(0)
while True:
print(val)
我知道这个测试只针对轴 0,但所有轴的输出仍然是 0.0。
下面我附上了演示代码,其中所有的值都被正确读取了。
import pygame, sys, time #Imports Modules
from pygame.locals import *
pygame.init()#Initializes Pygame
pygame.joystick.init()
joystick = pygame.joystick.Joystick(0)
joystick.init()#Initializes Joystick
# get count of joysticks=1, axes=27, buttons=19 for DualShock 3
joystick_count = pygame.joystick.get_count()
print("joystick_count")
print(joystick_count)
print("--------------")
numaxes = joystick.get_numaxes()
print("numaxes")
print(numaxes)
print("--------------")
numbuttons = joystick.get_numbuttons()
print("numbuttons")
print(numbuttons)
print("--------------")
loopQuit = False
while loopQuit == False:
# test joystick axes and prints values
outstr = ""
for i in range(0,4):
axis = joystick.get_axis(i)
outstr = outstr + str(i) + ":" + str(axis) + "|"
print(outstr)
# test controller buttons
outstr = ""
for i in range(0,numbuttons):
button = joystick.get_button(i)
outstr = outstr + str(i) + ":" + str(button) + "|"
print(outstr)
for event in pygame.event.get():
if event.type == QUIT:
loopQuit = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
loopQuit = True
# Returns Joystick Button Motion
if event.type == pygame.JOYBUTTONDOWN:
print("joy button down")
if event.type == pygame.JOYBUTTONUP:
print("joy button up")
if event.type == pygame.JOYBALLMOTION:
print("joy ball motion")
# axis motion is movement of controller
# dominates events when used
if event.type == pygame.JOYAXISMOTION:
# print("joy axis motion")
time.sleep(0.01)
pygame.quit()
sys.exit()
任何反馈将不胜感激。
代码丢失了对初始化操纵杆的引用。它需要维护一个内部 link 给它。请注意下面 class 中 self.
的使用。这将引用保留在 class 中,使“self.joystick”成为 member variable of the class. Python classes need the self.
notation (unlike lots of (all?) other object orientated languages). While editing I changed some of the names to match the Python PEP-8 style guide,希望没问题 ;)
class Controller:
def __init__( self, joy_index=0 ):
pygame.joystick.init() # is it OK to keep calling this?
self.joystick = pygame.joystick.Joystick( joy_index )
self.joystick.init()
def getAxisValue( self, axis ):
value = self.joystick.get_axis( axis )
return value
也许您没有考虑额外的代码,但是没有事件循环的 PyGame 程序最终会锁定。
