Question

我正在做节奏游戏。当“拍子”（箭头）击中某个坐标时，它消失。如果按下了相应的键，则游戏会增加玩家的分数。

但是当我运行我的代码时，它并没有增加得分。

这是我的代码：

import pygame
import time
import itertools

pygame.init()
SCREENWIDTH = 1000
SCREENHEIGHT = 650
screen = pygame.display.set_mode([SCREENWIDTH, SCREENHEIGHT])
screen.fill((255, 123, 67))
pygame.draw.rect(screen, (0, 255, 188), (0, 50, 1000, 650), 0)
myfont = pygame.font.SysFont('Ink Free', 30)

background = screen.copy()
clock = pygame.time.Clock()
stageon = True

sprites = pygame.sprite.Group()
class Player(pygame.sprite.Sprite):
    sprite = pygame.image.load("Sprites/lee.png")

    def __init__(self, *groups):
        super().__init__(*groups)
        self.image = Player.sprite
        self.rect = self.image.get_rect(topleft=(445, 550))
        self.pos = pygame.Vector2(self.rect.topleft)
        self.score = 0
    def update(self):
        key = pygame.key.get_pressed()
        dist = 3
        if key[pygame.K_DOWN]:
            self.rect.y += dist
        elif key[pygame.K_UP]:
            self.rect.y -= dist
        if key[pygame.K_RIGHT]:
            self.rect.x += dist
        elif key[pygame.K_LEFT]:
            self.rect.x -= dist

player = Player(sprites)

beatgroup = pygame.sprite.Group()
class Beat(pygame.sprite.Sprite):
    def __init__(self, ticks, image):
        super().__init__(beatgroup)
        self.image = image
        self.rect = self.image.get_rect()
        self.pos = pygame.Vector2(730, 100)
        self.path = itertools.cycle(((730, 100), (850, 100),))
        self.next_point = pygame.Vector2(next(self.path))
        self.speed = 2
        self.ticks = 200

    def update(self):
        move = self.next_point - self.pos
        move_length = move.length()
        if move_length != 0:
            move.normalize_ip()
            move = move * self.speed
            self.pos += move
        key = pygame.key.get_pressed()
        if self.pos == (850, 100):
            self.kill()

        #here's the problem area   
        if self.pos == (850, 100) and  key[pygame.K_DOWN] and self.image == pygame.image.load("Sprites/down.png"):
            player.score += 10
        elif self.pos == (850, 100) and key[pygame.K_UP] and self.image == pygame.image.load("Sprites/up.png"):
            player.score += 10
        elif self.pos == (850, 100) and key[pygame.K_LEFT] and self.image == pygame.image.load("Sprites/left.png"):
            player.score += 10
        elif self.pos == (850, 100) and key[pygame.K_RIGHT] and self.image == pygame.image.load("Sprites/right.png"):
            player.score += 10

        if move.length() == 0 or move_length < self.speed:
            self.next_point = pygame.Vector2(next(self.path))

        self.rect.topleft = self.pos



class Beat_gen(pygame.sprite.Sprite):
    def __init__(self, order):
        super().__init__(beatgroup)
        self.image = pygame.image.load("Sprites/beat_cropped.png")
        self.rect = self.image.get_rect(topleft=(730, 100))
        self.start_time = pygame.time.get_ticks()
        print(self.start_time)
        self.order = []
        self.picorder = []
        for i in order:
            self.order.append(i[0])
            self.picorder.append(i[1])
        self.currentbeat = 0
        self.LastBeat = 0
    def update(self):
        if self.currentbeat == len(self.order):
                stageon = False
        else:
            time_gone = pygame.time.get_ticks() - self.start_time
            if time_gone >= self.order[self.currentbeat] or self.currentbeat == 0:
                self.start_time = pygame.time.get_ticks()
                Beat(self.order[self.currentbeat], self.picorder[self.currentbeat])
                self.currentbeat += 1
                self.LastBeat = pygame.time.get_ticks()

class Hit_Line(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__(beatgroup)
        self.image = pygame.image.load("Sprites/hit-line.png")
        self.rect = self.image.get_rect(topleft=(873, 60))
        def update(self):
            self.image.draw()


beatgen = Beat_gen([(820, pygame.image.load("Sprites/left.png")), (410, pygame.image.load("Sprites/right.png")),(410, pygame.image.load("Sprites/left.png")),
                    (410, pygame.image.load("Sprites/right.png")),(410, pygame.image.load("Sprites/left.png")), (410, pygame.image.load("Sprites/right.png")),
                    (410, pygame.image.load("Sprites/left.png")), (410, pygame.image.load("Sprites/right.png")),(410, pygame.image.load("Sprites/left.png")),
                    (410, pygame.image.load("Sprites/right.png")),(410, pygame.image.load("Sprites/left.png")), (410, pygame.image.load("Sprites/right.png")),
                    (410, pygame.image.load("Sprites/left.png")), (410, pygame.image.load("Sprites/right.png")),(410, pygame.image.load("Sprites/left.png")),
                    (410, pygame.image.load("Sprites/right.png"))])

def main():
    while stageon:
        for events in pygame.event.get():
            if events.type == pygame.QUIT: 
                pygame.quit()
                return


        sprites.update()
        beatgroup.update()
        screen.blit(background, (0, 0))
        sprites.draw(screen)
        beatgroup.draw(screen)
        pygame.display.update()

        clock.tick(100)

if __name__ == '__main__':
    main()

另外，我测试分数是否上升的一个注释是，在我的原始代码中，分数显示在屏幕上。我也将其打印到控制台。为了证明这不是我不良的节奏游戏技能，我按住了一段时间（现在只是左右左右）。

我已经多次遍历我的代码以尝试发现问题，但找不到。

任何解释将不胜感激。

谢谢：）

Answer 1

这是我的未来！我如何解决的是在Beat类中添加了另一个名为direction的属性，该属性是一个包含“ left”，“ right”，“ up”或“ down”的字符串。

要分配此值，我去了Beat_gen初始化的部分，并在每个元组中添加了另一个值，如下所示： (820, pygame.image.load("Sprites/left.png"), "left")。然后，我进入Beat_gen类，添加了一个名为dirorder的列表（方向顺序），并循环遍历每个元组，获取第三个值并将其附加到列表中，就像对图片和时间。

然后将其添加到Beat初始化中作为分配它的参数； self.dirorder[self.currentbeat]

Pygame-该游戏将不会增加得分
