Question

我试图重新创建一个游戏，但我所需要的只是创建一个游戏结束功能，当玩家碰撞或无法跳过岩石时发生。我试图进行检查碰撞但玩家正在经过。当玩家与摇滚相撞时，我应该做什么或改变什么才能在屏幕上显示游戏？这是我的示例代码：

#---  Player Definition 
class Player(pygame.sprite.Sprite):
    #- Constructor
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.playing = False
        self.image = pygame.image.load("bcquestchar.png")
        self.rect = self.image.get_rect()
        self.color = BLUE
        self.rect.x = 50
        self.rect.y = 210
        self.goalY= 450
        self.gameover = False
    #- Allows Player to Jump
    def jump(self):
        self.goalY -= 25
    #- Imports & Displays player_image
    def draw(self, screen):
        screen.blit(player_image, [self.rect.x, self.rect.y])

#--- Rock definition
class Rock(pygame.sprite.Sprite):
    #- Constructor
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load("bcrocks.png")
        self.rect = self.image.get_rect()
        self.rect.x = random.randrange (0, 200)
        self.rect.y = 335
    #- Moves Rock
    def move(self):
        self.rect.x -= 3
    #- Imports & Displays rock_image
    def draw(self, screen):
        screen.blit(self.image, [self.rect.x + 700, self.rect.y])
# Loop until user closes pygame 
done = False

# How fast the screen updates
clock = pygame.time.Clock()

# Creates player
rock = Rock()
player = Player()
obstacles = pygame.sprite.Group()
obstacles.add(rock)

if pygame.sprite.spritecollide(player, obstacles, False):
    player.gameover = True

#----- Main Program Loop -----#
while not done:
    #movesound.play()
    #- Calls in draw_background function
    draw_background (screen, 0, 0)
    #- Tracks Events
    speed = 1
#--- Main Event Loop
    for event in pygame.event.get(): 
        if event.type == pygame.QUIT: 
            done = False

#- User is playing when M1 is clicked
    elif event.type == pygame.MOUSEBUTTONDOWN:  
        player.playing = True

    #- User jumps when playing and has not lost
    if(player.gameover == False and player.playing == True):
        player.jump()

#- Is the player playing?
if(player.playing == True):

    # Jump up when the up arrow is pressed
    if event.type == pygame.MOUSEBUTTONDOWN:
        currently_jumping = True
        going_up = True
        #hopsound.play()

    if currently_jumping == True:
        if player.rect.y < 188:
            going_up = False
        elif going_up == False and player.rect.y > 215:
            currently_jumping = False

        if going_up:
            player.rect.y -= 2
        elif going_up == False:
            player.rect.y += 2

    elif currently_jumping == False:
        if(player.rect.y > 600 or player.rect.y < 0):
            player.gameover = True    
        if(player.rect.y < 210):#player.goalY):
            player_moving_up = False

        elif(player.rect.y > 210):#player.goalY):
            player_moving_up = True

        if player_moving_up == True or player_moving_up == True:
            player.rect.y += 1
            player.rect.y -= 1
        player.goalY += 3


    if(timer3 > 120):
        timer3 = 0
        if(player.playing == True and player.gameover == False):
            score += 30

    #--- Draw and Move Rocks
    for rock in obstacles:
        rock.draw(screen)
        if(player.gameover == False):
            rock.move()
            rock.draw(screen)
            #rock.checkCollision(player.x, player.y)
        if pygame.sprite.spritecollide(player, obstacles, False):
            obstacles.remove(rock)
#----- Gameover        
        if(player.gameover == True):
            player.goalY = 600
            font = pygame.font.SysFont('Ariel', 50, True, False)
            text = font.render("Game Over", True, WHITE)
            screen.blit(text, [150, 100])

将Rock()设为pygame.sprite.Sprite课程，如果可能，请加入pygame.sprite.Group()。在这种情况下，您可以使用if pygame.sprite.spritecollide()检查检测：

rock = Rock()
player = Player()
obstacles = pygame.sprite.Group()
obsatcles.add(rock)
if pygame.sprite.spritecollide(player, obstacles, False):
    pass #Do something

使用pygame.sprite.Group()的好处是你可以使用它来帮助检测与玩家的碰撞和任何其他障碍。假设您在obstacles中有三个项目，它们都是rock的：

for rock in obstacles:
    if pygame.sprite.spritecollide(player, obstacles, False):
        obstacles.remove(rock)  #Removes the obstacle

将组放在精灵类之外和while循环之前。

对于摇滚乐队，请在你的init函数中使用它：

self.rect = self.image.get_rect()

所以它会是：

def __init__(self):
     pygame.sprite.Sprite.__init__(self)
     self.image = pygame.image.load("filename.png")
     self.rect = pygame.image.get_rect()

然后将此添加到您的while循环中：

for rock in obstacles:
    rock.move()
    rock.draw()

你的最后一堂课（不包括最后两个职能）将是：

class Rock(pygames.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load("bcrocks.png")
        self.rect = self.image.get_rect()
        self.rect.x = random.randrange (0, 200)
        self.rect.y = 335
