Python 3:当我按下一个键，然后按下另一个键时，pygame don'不要参加新的活动

Question

我有一个脚本，可以让一个"角色"在地图上移动，但当我按住一个方向，然后按下(按下然后释放(另一个键时，"在pygame.event_get((中的for event(("循环就不起作用了。我确实有一个"pygame.key.set_repet(("，我试图在每次释放键时更改"event"的值，但我不知道该怎么办。下面是脚本：

import math
import numpy as np
import random as rdm
import pygame
from pygame.locals import *
#functions :
def printScreen():
global delta
global Map
global player

x = (w-player.w)//2
xMap = x - player.x


y = (h-player.w)//2
yMap = player.w + y - Map.h + player.y

fenetre.fill((0, 0, 0))
fenetre.blit(Map.layer1, (xMap, yMap))
fenetre.blit(player.image, (x, y))
pygame.display.flip()
#variables :
h, w = 600, 700
delta = 1 #size of a pixel
run = True
moving = False
#constants :
zeros = tuple([0 for i in range(323)])
directions = ['up', 'down', 'right', 'left']
#pygame initialisation :

pygame.init()
clock = pygame.time.Clock()
fenetre = pygame.display.set_mode((w*delta, h*delta))
pygame.key.set_repeat(40, 40)
#classes :
class player :
def __init__(self, save) :
File = open(save + 'savedata.txt')
Text = File.read()
File.close
noLine = 1
nbCharacters = 0
lineStart = 0
for i in range(len(Text)) :
if Text[i] == 'n' :
line = Text[lineStart:i]
lineStart = i+1
if noLine == 1 :
nickName = line
if noLine == 2 :
x = int(line)
if noLine == 3 :
y = int(line)
noLine += 1
self.image = pygame.image.load(save + 'player.png')
self.w = self.image.get_width()
self.h = self.image.get_height()
self.nickName = nickName
self.x = x
self.y = y
self.direction = 'down'
player = player("dataplayersave01")
class backGround :
def __init__(self, directory) :
self.layer1 = pygame.image.load(directory)
self.w = self.layer1.get_width()
self.h = self.layer1.get_height()
Map = backGround("data"+"\"+"town.png")
#images :
#main pygame loop :

while run :
clock.tick(120)
for event in pygame.event.get() :
if event.type == QUIT :
run = False
if event.type == KEYUP :
event = 0

keys = pygame.key.get_pressed()
arrows = keys[273 : 277]
for i in range(4) :
if player.direction == directions[i] and arrows[i] == 0 :
moving = False

if keys == zeros :
moving = False

if keys[pygame.K_UP] :
player.y += player.w
if not moving :
player.direction = 'up'
moving = True
if keys[pygame.K_DOWN] :
player.y -= player.w
if not moving :
player.direction = 'down'
moving = True
if keys[pygame.K_RIGHT] :
player.x += player.w
if not moving :
player.direction = 'right'
moving = True
if keys[pygame.K_LEFT] :
player.x -= player.w
if not moving :
player.direction = 'left'
moving = True
print(player.direction, keys[273 : 277])
printScreen()

pygame.quit()

arrows=keys[273:277]是指pygame.key.get_pressed((中包含箭头键的部分。

问题是，只有在发生新事件时才检查键数组。您希望在每个循环中检查键数组。你只需要调整一下你的缩进。

这是更新后的代码：

while run :
clock.tick(10)
for event in pygame.event.get() :  # check for new event
if event.type == QUIT :
run = False
if event.type == KEYUP :
event = 0

keys = pygame.key.get_pressed()  # always check this
arrows = keys[273 : 277]
for i in range(4) :
if player.direction == directions[i] and arrows[i] == 0 :
moving = False

if keys[pygame.K_SPACE] : print('--------------------- space')
if keys == zeros :
moving = False

.............

pygame.quit()
