标题: 关于按键控制打飞机游戏的问题
我想让w按下后小人就一直往上走而不是每次移动都要按一次 w 想用一个标志量来记录但是效果不对

求大家帮忙看下谢谢！

这是程序：

import pygame
from sys import exit
import random
class Hero:
def __init__(self):
      self.image = pygame.image.load('image\huaji.jpg').convert_alpha()
      self.x = random.randint(100,800) - self.image.get_width() / 2
      self.y = random.randint(200,500) - self.image.get_height() / 2
      self.speed = 20

def move(self,x,y):
      self.x = x
      self.y = y

class Bullet:
def __init__(self):
      self.x = 0
      self.y = 0

pygame.init()
screen = pygame.display.set_mode((1000,500),0,32)
pygame.display.set_caption("Fly_game")
bg = pygame.image.load("image\\bg.jpg").convert()
clock = pygame.time.Clock()
hero = Hero()
w_flag = 0
s_flag =0
a_flag =0
d_flag = 0
while True:
for event in pygame.event.get():
      if event.type == pygame.QUIT:
         pygame.quit()
         exit()
      if event.type == pygame.KEYDOWN:
         if event.key == pygame.K_w:
            w_flag = 1
         elif event.key == pygame.K_s:
            s_flag =1
         elif event.key == pygame.K_a:
            a_flag =1
         elif event.key == pygame.K_d:
            d_flag =1
      if event.type == pygame.KEYUP:
         if event.key == pygame.K_w:
            w_flag = 0
         elif event.key == pygame.K_s:
            s_flag =0
         elif event.key == pygame.K_a:
            a_flag =0
         elif event.key == pygame.K_d:
            d_flag =0
      if w_flag:
         hero.y -= hero.speed
      if s_flag:
         hero.y += hero.speed
      if a_flag:
         hero.x -= hero.speed
      if d_flag:
         hero.x += hero.speed
      if hero.x < 0:
         hero.x = 0
      if hero.x > 1000:
         hero.x = 1000
      if hero.y < 0:
         hero.y = 0
      if hero.y > 800:
         hero.y = 800
print(d_flag,hero.x)
screen.blit(bg, (0, 0))
screen.blit(hero.image,(hero.x,hero.y))
pygame.display.update()
clock.tick(50)

设置标志放在 event 里，小人移动不应该放在 event 里
