我想制作一个游戏,让我有来自屏幕两侧的敌人。现在,我有了它,以便敌人一次一次在屏幕上滚动。我希望每次有更多的人来,慢慢增加他们碰到的频率。这是我的代码import pygame, sys, time, randomfrom pygame.locals import *pygame.init()winW = 1000winH = 600surface = pygame.display.set_mode ((winW, winH),0,32)pygame.display.set_caption ('Moving Orc')class Enemy: def __init__(self, char, startY, startX): self.char=char self.startY=startY self.startX=startX self.drawChar() def drawChar (self): self.space = pygame.image.load (self.char) self.spaceRect = self.space.get_rect () self.spaceRect.topleft = (self.startX,self.startY) self.moveChar() def moveChar (self): if self.startX == 0: self.xMoveAmt = 5 elif self.startX == 800: self.xMoveAmt = -5 while True: surface.fill ((255,255,255)) self.spaceRect.left += self.xMoveAmt surface.blit (self.space, self.spaceRect) pygame.display.update() time.sleep (0.02) if self.spaceRect.right >= winW: surface.fill ((255,255,255)) break elif self.spaceRect.left <= 0: surface.fill ((255,255,255)) break#MAINLINEwhile True: enemyList=[] leftOrRight = random.randint(0,1) if leftOrRight == 0: leftOrRight = 0 elif leftOrRight == 1: leftOrRight = 800 enemyList.append(Enemy(("orc.png"), random.randint(50, 500), leftOrRight)) for i in range (0,len(enemyList)): enemyList[i].drawChar() break我拥有它,以便每次进入循环时,它都会重置它在我制作的类中运行的列表。一个人将从左侧或右侧穿过屏幕。我什至要从哪里开始?
