import pygame
# itilaze
pygame.init()
# title and icon
icon = pygame.image.load("satanic.png")
pygame.display.set_caption("demo")
pygame.display.set_icon(icon)
playerImg = pygame.image.load("pixil-frame-0 (1).png")

Py = 480
def player(x,y):
screen.blit(playerImg,(x,y))
# ekran boyutu
screen = pygame.display.set_mode((800,600))
# LOOP
running = True
while running:
screen.fill((50,3,10)) # rgb
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
Pxc = -0.5
if event.key == pygame.K_RIGHT:
Pxc = 0.5
if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
Pxc = 0
Px += Pxc
player(Px,Py) # adam
pygame.display.update()
如果你们能帮助我就好了 我今天开始学习 phyton
解决方法
Pxy
仅在事件循环中设置。因此,如果没有事件发生,则永远不会设置 Pxc
。在应用程序循环之前初始化 Pxc
:
Pxc = 0 # <--- ADD THIS
running = True
while running:
# [...]
Px += Pxc
