游戏精灵碰撞...我怎么能欺骗精灵碰撞？

Question

from numpy import place
import pygame, sys ,random as ran 
start = True
class Player(pygame.sprite.Sprite):
    def __init__(self, pos_x, pos_y):
        super().__init__()
        self.attack_animation = False
        self.sprites_1 = []
        self.sprites_1.append(pygame.image.load('crossHair.png'))
        self.sprites_1.append(pygame.image.load('crossHair_2.png'))
        self.sprites_1.append(pygame.image.load('crossHair_3.png'))
        self.sprites_1.append(pygame.image.load('crossHair_4.png'))
        self.sprites_1.append(pygame.image.load('crossHair_5.png'))
        self.sprites_1.append(pygame.image.load('FIRE.png'))
        self.current_sprite = 0
        self.image = self.sprites_1[self.current_sprite]
        self.image.set_colorkey('white')
        for items in self.sprites_1:
            items.set_colorkey('white')
        self.rect = self.image.get_rect()
        self.rect.topleft = [pos_x,pos_y]
        

    def attack(self):
        self.attack_animation = True
        self.image.set_colorkey('white')

    def update(self,speed):
        self.image.set_colorkey('white')
        if self.attack_animation == True:
            self.current_sprite += speed
            if int(self.current_sprite) >= len(self.sprites_1):
                self.current_sprite = 0
                self.attack_animation = False
                print('shot')
            self.image = self.sprites_1[int(self.current_sprite)]
            # self.image = self.sprites_1[int(self.current_sprite)]
        mouse = pygame.mouse.get_pos()
        self.rect = mouse
class enemy(pygame.sprite.Sprite):
    def __init__(self, pos_x, pos_y):
        super().__init__()
        self.image = pygame.image.load('sp_1.png')
        self.rect = self.image.get_rect()
        self.rect.center = [pos_x, pos_y]
        self.image.set_colorkey((255,255,255))
# General setup
pygame.init()
pygame.mouse.set_visible(0)
clock = pygame.time.Clock()
# Game Screen
screen_width = 400
screen_height = 400
mouse = pygame.mouse.get_pos()
screen = pygame.display.set_mode((screen_width,screen_height))
pygame.display.set_caption("Sprite Animation")

# Creating the sprites and groups


moving_sprites = pygame.sprite.Group()
crosshair = Player(mouse[0],mouse[1])
enemy_x = ran.randint(18,387)
enemy_y = ran.randint(18,387)
print(enemy_x,enemy_y)
enemy_ = enemy(enemy_x,enemy_y)
moving_sprites.add(enemy_,crosshair)
while True:
    # Player.set_pos(*pygame.mouse.get_pos())
    globals()['mouse'] = pygame.mouse.get_pos()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            if pygame.mouse.get_pressed()[0]:
                crosshair.attack()
                enemy.checkCollision(enemy,crosshair,enemy_)
                # enemy.attack()
                # pygame.sprite.spritecollide(Player,enemy,True)
    screen.fill((120,220,150))






    #this is causing the problem
    get_hit = pygame.sprite.spritecollide(Player,enemy,True)
    




# Drawing
    screen.set_colorkey('white')
    moving_sprites.draw(screen)
    moving_sprites.update(0.08)
    pygame.display.flip()
    clock.tick(120)
    

在get_hit=pyGame.sprite的第82行，我检查sprite碰撞的移动时，它会给出错误提示：“：File”c:\Users\pc\VS_PYTHON_PY\pyGame.PY“。”。spritecollide（Player，敌方，True）文件“C:\python py\lib\site packages\pygame\sprite.py”，第1682行，位于spritecrollide default_sprite_collide_func=sprite.rect中。collectrect AttributeError:类型对象“Player”没有属性“rect”

为什么会这样，你能解决这个问题吗

Answer 1

pygame.sprite的参数。spritecollide必须是Sprite和Group类的实例对象Player和敌手十字准线enemy_是对象。为敌人创建一个组，并检测十字准线和敌人组之间的碰撞：

crosshair = Player(mouse[0],mouse[1])

enemyGroup = pygame.sprite.Group()
enemy_ = enemy(enemy_x,enemy_y)
enemyGroup.add(enemy_)

while True:
    # [...]

    get_hit = pygame.sprite.spritecollide(crosshair, enemyGroup, True)

另请参见如何在类中编程冲突？以及如何在pygame中检测碰撞？。

另请参阅 Python 代码的样式指南：类名通常应使用 CapWords 约定。类的名称应为“敌人”，而不是“敌人”。
