Question

我正在研究在pygame中制作精灵的更简单方法（仅限我）。我有这3个文件

文件1：Tests.py：

import pygame
from pygame.locals import *
import MySprites
import SpecialFunctions

Sprites = []

NewScreen = SpecialFunctions.Level('NewProject', '2D-AboveView', (960, 540), Sprites)

Sprites = []

imgDolu = [pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-8.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-9.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-10.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-11.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-12.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-13.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-14.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-15.png')]
imgNahoru = [pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-0.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-1.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-2.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-3.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-4.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-5.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-6.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-1-7.png')]
imgDoleva = [pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-0.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-1.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-2.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-3.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-4.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-5.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-6.png'), pygame.image.load('HeroSprites/HeroSpriteSheet2 [www.imagesplitter.net]-0-7.png')]

imgUtociNahoru = []; imgUtociDolu = []; imgUtociDoleva = []; imgUtociDoprava = []
Player1 = MySprites.Player_Type_AboveView(movingUp=imgNahoru, movingDown=imgDolu, movingLeft=imgDoleva, movingRight=imgDoprava, swingingUp=imgUtociNahoru, swingingDown=imgUtociDolu, swingingLeft=imgUtociDoleva, swingingRight=imgUtociDoprava, controlUp=pygame.K_w, controlDown=pygame.K_s, controlLeft=pygame.K_a, controlRight=pygame.K_d, controlSwing=pygame.K_k, speed=5, x=960/2, y=540/2)
Sprites.append(Player1)

NewScreen.mainloop()

这是我的一般文件，这是我正在测试的地方。

文件2：SpecialFunctions.py：

import pygame
import MySprites
from pygame.locals import *

class Level:
    def __init__(self, Name, Type, screen_size, AllSprites):

        """Inicialization of Project"""

        black = (0, 0, 0)
        screen_size = screen_size
        self.screen = pygame.display.set_mode(screen_size)
        pygame.display.set_caption(Name)
        self.screen.fill(black)
        pygame.display.update()
        self.ProjectSprites = AllSprites

        self.Running = True

        self.type = Type

        self.keys_pressed_list = []

    def screen_Update(self):
        if self.Running:
            self.screen.fill((0, 0, 0))
            for sprite in self.ProjectSprites:
                sprite.update(sprite, self.screen)
                sprite.draw(self.screen)
            pygame.display.update()

    def mainloop(self):

        """Running program"""

        while self.Running:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    self.Running = False
                    break
                elif event.type == pygame.KEYDOWN:
                    self.keys_pressed_list.append(event.key)
                elif event.type == pygame.KEYUP:
                    self.keys_pressed_list.remove(event.key)
            if self.Running:
                self.screen_Update()
            pygame.time.delay(100)

这是包含一些我可以用于屏幕的工具的文件。

文件3：MySprites.py：

import pygame

        self.phase = 0
        self.imgGroup = self.imgDown
        self.image = self.imgGroup[self.phase]

        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y

        self.speed = speed
        self.Swinging = False

    def update(self, Scene):
        moved = False
        x = 0
        y = 0

        #Player controls
        if self.controls_Up in Scene.keys_pressed_list:
            self.imageGroup = self.imgUp
            y = -self.speed
            moved = True

        elif self.controls_Down in Scene.keys_pressed_list:

            moved = True


        elif self.controls_Swing in Scene.keys_pressed_list:

            Swinging = {
                self.imgDown : self.swingingDown,
                self.imgUp: self.swingingUp,
                self.imgLeft: self.swingingLeft,
                self.imgRight: self.swingingRight
            }

            self.imageGroup = Swinging[self.imageGroup]

            self.Swinging = True

            moved = True

        if moved or self.phase != 0:
            if moved:
                self.phase = (self.phase + 1) % 4
            else:
                self.phase = 0

            self.image = self.imageGroup[self.phase]
            self.rect.x += x
            self.rect.y += y
            self.Swinging = False

这是播放器类的文件 - 顺便说一句。摆动是WIP。

我正在尝试制作可以移动的窗口和播放器（WASD），但它只能制作黑色窗口。我需要知道的是为什么？！

我正在使用python 3.6
希望这个问题不是那么愚蠢

Answer 1

您添加播放器精灵的列表与您在Level实例中使用的列表不同。看看这里：

...
import SpecialFunctions

Sprites = []

NewScreen = SpecialFunctions.Level('NewProject', '2D-AboveView', (960, 540), Sprites)

Sprites = []

...

因此，当您将NewScreen个实例添加到另一个未在任何地方使用的列表时，Player_Type_AboveView只会看到第一个列表，该列表始终为空。

只需删除第二条Sprites = []行。

此外，它（大多数情况下）最好使用Group而不是列表来管理您的精灵。
