pygame玩家不动

如何解决pygame玩家不动

我正在制作一款涉及玩家左右移动的游戏。但是，在下面的代码中，播放器无法移动。谁能告诉我为什么player1精灵不移动？它出现在游戏屏幕上，但是当我按下移动键时，播放器不会向左或向右移动。

代码：

import pygame
import sys

pygame.init()

game_screen = pygame.display.set_mode((600,600))
pygame.display.set_caption("Whiskey Goggles")

bg = pygame.image.load("bg.png")
bg_image = pygame.transform.scale(bg,(600,600))

class Player:

    def __init__(self,image_path,width,height,x,y):

        self.image_path = image_path
        self.width = width
        self.height = height
        self.x = x
        self.y = y

        player = pygame.image.load(image_path)
        self.player_main = pygame.transform.scale(player,(width,height))

    def draw(self,background):

        background.blit(self.player_main,(self.x,self.y))

#Main game

game_on = True
while game_on:

    clock = pygame.time.Clock() 
    clock.tick(60)

    direction = 0

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_on = False
            pygame.quit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                direction = 1
            elif event.key == pygame.K_LEFT:
                direction = -1
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_RIGHT or event.key == pygame.K_LEFT:
                direction = 0

    game_screen.fill((0,0))
    game_screen.blit(bg_image,(0,0))

    player1 = Player("glass.png",70,25,500)
    player1.draw(game_screen)

    if direction > 0:
        player1.x = player1.x + 10
    elif direction < 0:
        player1.x = player1.x - 10

    pygame.display.update()

quit()

解决方法

您要在同一位置的每个循环中创建一个新播放器（并重置direction）。在循环之外创建它。

game_on = True
player1 = Object("glass.png",70,25,500)  # Create the player here instead.
direction = 0  # The same with direction.
while game_on:

    clock = pygame.time.Clock() 
    clock.tick(60)

    # direction = 0 Don't reset the direction every loop.

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_on = False
            pygame.quit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                direction = 1
            elif event.key == pygame.K_LEFT:
                direction = -1
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_RIGHT or event.key == pygame.K_LEFT:
                direction = 0

    game_screen.fill((0,0))
    game_screen.blit(bg_image,(0,0))

    # player1 = Object("glass.png",500)  # Don't do this.
    player1.draw(game_screen)

    if direction > 0:
        player1.x = player1.x + 10
    elif direction < 0:
        player1.x = player1.x - 10

       
    pygame.display.update()
