今天尝试重新制作《PYTHON从入门到实践》飞机大战小游戏

初始化设置，主要是设置背景还有PYGAME的游戏框框

import pygame
class plant_game():
    def __init__(self):
        pygame.init()
        self.screen = pygame.display.set_mode((800,600))
        self.bg_color = (230,230,230)
        self.ship_speed_factor = 1.5

控制飞船移动模块：

import sys
import pygame
from ship1 import Ship
def check_events(ship):
    #控制飞船移动
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                ship.moving_right = True
            elif event.key == pygame.K_LEFT:
                ship.moving_left = True
            elif event.key == pygame.K_UP:
                ship.moving_up = True
            elif event.key == pygame.K_DOWN:
                ship.moving_down = True
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_RIGHT:
                ship.moving_right = False
            elif event.key == pygame.K_LEFT:
                ship.moving_left = False
            elif event.key == pygame.K_UP:
                ship.moving_up = False
            elif event.key == pygame.K_DOWN:
                ship.moving_down = False




def update_screen(ai_settings,screen,ship):
    # 更新屏幕，将颜色和飞船印上去
    screen.fill(ai_settings.bg_color)
    ship.blitme()
    ship.update()
    pygame.display.flip()

这是ship模块，目前这个ship模块我摸索出来了上下左右飞船飞行，并且左右可以设置飞船不会穿出边界，但是上下却会穿出去。。目前没找出问题。。明天试试看看能不能找出问题。

import pygame
from settings1 import plant_game


class Ship():
    def __init__(self, ai_settings, screen):
        # 将ai.setting.scrren放入screen行参中
        self.screen = screen
        self.ai_settings = ai_settings
        self.image = pygame.image.load('ship.bmp')
        self.rect = self.image.get_rect()
        self.screen_rect = screen.get_rect()
        # 将每艘新飞船放在屏幕底部中央
        self.rect.centerx = self.screen_rect.centerx
        self.rect.bottom = self.screen_rect.bottom
        self.stop = float(self.rect.centerx)
        #这个stop，可以忽略
        self.moving_right = False
        self.moving_left = False
        self.moving_up = False
        self.moving_down = False

    def update(self):
        if self.moving_right:
            self.rect.centerx += self.ai_settings.ship_speed_factor
            if self.rect.centerx > 800:
                self.rect.centerx -= 1.5
                self.rect.centerx = 800
        elif self.moving_left:
            self.rect.centerx -= self.ai_settings.ship_speed_factor
            if self.rect.centerx < 0:
                self.rect.centerx += 1.5
                self.stop = True
        elif self.moving_up:
            self.rect.bottom -= self.ai_settings.ship_speed_factor
    		#就是这里了。。我不知道咋设置不超出去？？
        elif self.moving_down:
            self.rect.bottom += self.ai_settings.ship_speed_factor


    def blitme(self):
        '''在指定位置绘制飞船'''
        self.screen.blit(self.image, self.rect)

启动程序

import pygame
import sys

from settings1 import plant_game
from ship1 import Ship
import checkcheck as gf

def run_game():
    pygame.display.set_caption("Alien Invasion")
    ai_setting = plant_game()
    ship = Ship(ai_setting,ai_setting.screen)
    # ship看做是一个矩形
    while True:
        gf.check_events(ship)
        gf.update_screen(ai_setting,ai_setting.screen,ship)
run_game()

明天看看能不能把外星人和子弹做出来，加油。
