player_image = pygame.image.load("bcquestchar.png")
player_image.set_colorkey(WHITE)
def draw_background(screen, x, y):
    pygame.draw.line(screen, ground_GREEN, [0, 400], [700, 400], 200)
    pygame.draw.line(screen, sky_BLUE, [0,0], [700,0], 400)
    pygame.draw.line(screen, sky_WHITE, [0, 270], [700, 270], 150)

#jumping player definition 
class Player(pygame.sprite.Sprite):
    def __init__(self):
        self.playing = False
        self.color = BLUE
        self.x = 50
        self.y = 210
        self.goalY= 450
        self.gameover = False
    def jump(self):
        self.goalY -= 45
    def draw(self, screen):
        screen.blit(player_image, [self.x, self.y])       

#create player
player = Player()

只需做另一个函数，以确保当您的精灵底部触摸屏幕底部时，它会停止在那里，等待任何其他命令。例如：

if self.x >= 1000:    
    self.x = 1000

上述代码意味着如果

位置大于或等于1000，则将

设置为1000，使其不会再降低。数字也可以根据您的需要进行更改。您还需要调用

update

函数，因为我们需要它来工作：

def update(self):        #Put the function into your Player class
    if self.x >= 1000:
        self.x = 1000

#Put the following the while loop or just call it
player = Player()
player.update()    #Call update()

移动播放器后，必须检查其位置并进行校正

您应该使用

pygame.Rect

，因为它很有用

它不是完整的代码，也不使用

rect

方法来检查冲突，但它显示了如何启动冲突

# jumping player definition

class Player(pygame.sprite.Sprite):

    def __init__(self):

        self.image = pygame.image.load("bcquestchar.png")
        self.image.set_colorkey(WHITE)

        self.playing = False
        self.color = BLUE

        # use rect to keep size and position
        self.rect = self.image.get_rect()
        self.rect.x = 50
        self.rect.y = 210

        self.goalY= 450
        self.gameover = False

        #self.speed_x = 0
        #self.speed_y = 0
        #self.gravity = 1

    def jump(self):
        self.goalY -= 45

    def draw(self, screen):
        screen.blit(self.image, self.rect)       

    #def event_handler(self, event):
    #    # if pressed key then change speed

    def update(self):
        # move player 
        #self.rect.x += self.speed_x
        #self.rect.y += self.speed_y

        #self.speed_y += self.gravity

        # check collision with grass
        if self.rect.bottom > grass_rect.top:

            # player below grass then move it up
            self.rect.bottom = grass_rect.top:

# ---

# draw other objects
def draw_background(screen, x, y):
    pygame.draw.line(screen, ground_GREEN, grass_rect, 200)

# ---

# create player
player = Player()

# create object rect to draw it and check collision with player
grass_rect = pygame.Rect(0, 400, 700, 400)

# move player and check collision with objects
player.update()

你有player

rect

和grass

rect

-你可以比较player底部和grass

top
