我最近实施了一个敌人，该敌人会定期在屏幕上的指定点射击。但是，在尝试使玩家适应这一点时，它拒绝工作。由于敌人类别是在房间模块中定义的，然后在主游戏模块中定义的，因此我不确定如何在敌人模块中称呼玩家rect。
工作代码如下：
游戏模组
import pygame
from constants import *
from player import Player
from pygame.math import Vector2
from enemy import *
from Rooms import Room0
pygame.init()
screen_rect = pygame.display.set_mode([500, 500])
pygame.display.set_caption(‘Labyrinth’)
all_sprites_list = pygame.sprite.Group()
projectiles = pygame.sprite.Group()
enemy_sprites = pygame.sprite.Group()
Assign rooms
rooms = []
room = Room0()
rooms.append(room)
current_room_no = 0
current_room = rooms[current_room_no]
Spawn player
player = Player(50, 50)
all_sprites_list.add(player)
clock = pygame.time.Clock()
done = False
—– Event Loop
while not done:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
—– Game Logic
all_sprites_list.update()
current_room.projectiles.update()
current_room.enemy_sprites.update()
screen_rect.fill(GREEN)
all_sprites_list.draw(screen_rect)
current_room.projectiles.draw(screen_rect)
current_room.enemy_sprites.draw(screen_rect)
pygame.display.flip()
clock.tick(60)
pygame.quit()
客房模块
import pygame
from enemy import Enemy
import Projectile
from pygame.math import Vector2
class Room(object):
enemy_sprites = None
projectiles = None
def init(self):
self.enemy_sprites = pygame.sprite.Group()
self.projectiles = pygame.sprite.Group()
class Room0(Room):
def init(self):
super().init()
enemy = Enemy(380, 280, self.projectiles)
self.enemy_sprites.add(enemy)
播放器模块
from constants import *
import pygame
class Player(pygame.sprite.Sprite):
def init(self, x, y):
super().init()
self.image = pygame.Surface([15, 15])
self.image.fill(BLACK)
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
敌人模块
from constants import *
import pygame
from Projectile import Bullet
from pygame.math import Vector2
target = Vector2(400, 400)
class Enemy(pygame.sprite.Sprite):
def init(self, x, y, projectiles):
super().init()
self.image = pygame.Surface([10, 10])
self.image.fill(RED)
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.previous_time = pygame.time.get_ticks()
self.shoot_delay = 1000
self.speed = 12
self.projectiles = projectiles
def update(self):
now = pygame.time.get_ticks()
if now – self.previous_time > self.shoot_delay:
self.previous_time = now
bullet = Bullet(self.rect.x, self.rect.y, target)
self.projectiles.add(bullet)
弹丸模块
import pygame
from constants import *
from pygame.math import Vector2
class Bullet(pygame.sprite.Sprite):
def init(self, x, y, target):
super().init()
self.image = pygame.Surface((10, 10))
self.image.fill(RED)
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.position = Vector2(self.rect.x, self.rect.y)
direction = target – self.position
radius, angle = direction.as_polar()
self.image = pygame.transform.rotozoom(self.image, -angle, 1)
self.velocity = direction.normalize() * 11
def update(self):
self.position += self.velocity
self.rect.center = self.position
解决方案
There’s an answer you want, and an answer you need. Respectively:
SomeModule.py:
from game import player # imports the Player instance you’ve created in the main module
some_func(player) # as argument
player.another_func # method access
Now, that’s the way you’d normally access that kind of stuff, and this would be perfectly fine. In this case though:
a) You’ll spawn a whole new game loop, because you put the game setup at module scope rather than in some function or, at very least, directly under an if name == ‘main‘. Importing a module executes all the code in the module scope.
b) The very fact you have to import a non-singleton instance, directly, is a code smell – what the very existence of this problem should signal to you is that you likely have a place where your bits of code must be able talk to each other, but you have nothing unambiguously responsible for mediating that process.
So, to address the second part of my promised answer: you should not let this problem occur in the first place – build something dedicated to managing players and enemies, import just the class definitions, then instance and interface between them in the manager.
