我已经为我的flappy龙创建了hitboxes，但是hitboxes要么不碰撞，要么不产生输出。我该怎么解决这个问题呢？

Question

我正在尝试为我的Python编程类创建一个flappybird游戏，我使用了像drag.hit()这样的提示，这会导致它们在每次命中框发生冲突时打印(“点击”)。然而，龙和笨拙的hitbox的碰撞不起作用，我似乎不能让它起作用。

下面是我的代码：

    pygame.init()

class player(object):   **class for dragon**
    def __init__(self, x, y, width, height):
        self.hitbox = (self.x + 5, self.y +3, 67, 65)

 def draw(self,win):     **drawing of hitbox for dragon**
        self.hitbox = (self.x + 5, self.y +3, 67, 65)     
        pygame.draw.rect(win, (255, 0, 0), self.hitbox, 2)

    def hit(self):        **During collision of hitbox, print hit**
        print("hit")


class stumpy(object):    **class for obstacle 1**
    def __init__(self, x, y, width, height):
        self.hitbox = (self.x + 8, self.y+10, self.width - 18, self.height-15)


    def draw(self, win):
        win.blit(pygame.transform.scale(self.walkLeft[self.count//3], (75, 200)), (self.x, self.y))      #fx to scale up or down object. transform, dimension, placement
        pygame.draw.rect(win, (255, 0, 0), self.hitbox, 2)  #arguments - window, colour, dimension, thickness
        self.hitbox = (self.x + 8, self.y+10, self.width - 18, self.height-15) #x-start, y-start, length, breath

class stumper(object):      **class for obstacle 2**
    def __init__(self, x, y, width, height):

        self.hitbox = (self.x + 8, self.y+10, self.width - 18, self.height-20)     


    def draw(self,win):
        self.hitbox = (self.x + 8, self.y+10, self.width - 18, self.height-20)
        pygame.draw.rect(win, (255,0,0), self.hitbox, 2)
        win.blit(pygame.transform.scale(self.walkLeft[self.count//1], (75,200)), (self.x,self.y))


def redrawGameWindow():
    global walkCount
    win.blit(bg, (bgX,0))  # This will draw our background image at (0,0)
    win.blit(bg, (bgX2,0))  # This will draw our background image at (1024,0)
    drag.draw(win)

    for obstacle in obstacles:
        obstacle.draw(win)

    pygame.display.update()

speed = 30             **assign variable for fps**
drag = player(95, 396//2, 75, 73)       #class for dragon, unnecessary
stump = stumpy(810, 310, 75, 200)     #class for stump, unnecessary
Istump = stumper(810, -20, 75, 200)


obstacles= []
#main loop
run = True
while run:
    redrawGameWindow()
    pygame.time.delay(25)

    for obstacle in obstacles:

        if drag.hitbox[1] < Istump.hitbox[1] + Istump.hitbox[3] and drag.hitbox[1] + drag.hitbox[3] > stump.hitbox[1]:      #must create player instance for this to work so using class is useless
            if drag.hitbox[0] + drag.hitbox[2] > Istump.hitbox[0] and drag.hitbox[0] < Istump.hitbox[0] + Istump.hitbox[2]:
                 if drag.hitbox[0] + drag.hitbox[2] > stump.hitbox[0] and drag.hitbox[0] < stump.hitbox[0] + stump.hitbox[2]:
                     drag.hit()
                     obstacles.append(stumpy(250, 250, 100, 100))



    redrawGameWindow()

pygame.quit()

在你的player类中，对你的hitbox使用pygame rect：

self.hitbox = pygame.Rect(self.x + 5, self.y +3, 67, 65)

然后对您的对象执行相同的操作，以便玩家和障碍物都是pygame.Rect对象。要检测玩家是否在障碍物中，只需使用：

if player.hitbox.colliderect(obstacle.hitbox):
    print('hit')
