Python和Pygame-我正在嘗試制作可移動的窗口和播放器（WASD），但它僅制作黑色窗口。

Question

我正在研究在pygame中制作精靈的更簡單方法（僅對我而言）。 我有這3個檔案

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 = []

Sprites.append(Player1)

NewScreen.mainloop()

多數民眾贊成在我的普通文件，這是我正在測試。

        self.screen = pygame.display.set_mode(screen_size)
        pygame.display.set_caption(Name)

該文件包含一些我可以在屏幕上使用的工具。

這是播放器類-Btw的文件。 擺動是在制品。

我正在嘗試制作可移動的窗口和播放器（WASD），但它只能制作黑色窗口。 我需要知道的是為什么？！

• 我正在使用python 3.6

• 希望這個問題不是那么愚蠢

Answer 1

您添加播放器精靈的列表與您在Level實例中使用的列表不同。 在這里看看：

...
import SpecialFunctions

Sprites = []

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

Sprites = []

...

因此，當您將Player_Type_AboveView實例添加到另一個未在任何地方使用的列表時， NewScreen只會看到第一個列表，該列表始終為空。

只需刪除第二個Sprites = []行。

而且，（大多數時候）最好使用一個Group而不是一個列表來管理您的精靈。
