python 打飞机项目 (实战一)

第一步定义 main 函数:

# -*- coding=utf-8 -*-

import pygame,time

from Plane import Plane

from pygame.locals import *

def key_control(plane_temp):

    # 获取事件，比如按键等

    for event in pygame.event.get():

        # 判断是否是点击了退出按钮

        if event.type == QUIT:

            print("exit")

            exit()

        # 判断是否是按下了键

        elif event.type == KEYDOWN:

            # 检测按键是否是a或者left

            if event.key == K_a or event.key == K_LEFT:

                print('left')

                plane_temp.move_left()

            # 检测按键是否是d或者right

            elif event.key == K_d or event.key == K_RIGHT:

                print('right')

                plane_temp.move_right()

            # 检测按键是否是空格键

            elif event.key == K_SPACE:

                print('space')

                plane_temp.fire()

def main():

    screen = pygame.display.set_mode((480, 852), 0, 32)

    background = pygame.image.load("./resource/background.png")

    # 创建一个飞机对象

    plane = Plane(screen, 210, 700)

    while True:

        screen.blit(background, (0, 0))

        plane.display()

        key_control(plane)

        pygame.display.update()

        time.sleep(0.01)

if __name__ == '__main__':

    main()

创建飞机类

---

import pygame

from Bullet import Bullet

class Plane(object):

    image = None

    bullet_list = []

    def __init__(self, screen_temp, x, y):

        self.screen = screen_temp

        self.x = x

        self.y = y

        self.img_load()

    def img_load(self):

        self.image = pygame.image.load("./resource/hero1.png")

    def display(self):

        self.screen.blit(self.image, (self.x, self.y))

        for bullet in self.bullet_list:

            print(bullet)

            bullet.display()

            bullet.move()

    def move_left(self):

        self.x -= 10

    def move_right(self):

        self.x += 10

    def fire(self):

        self.bullet_list.append(Bullet(self.screen, self.x, self.y))

创建子弹类:

import pygame

class Bullet(object):

    def __init__ (self, screen_temp, x, y):

        self.x = x + 40

        self.y = y - 20

        self.screen = screen_temp

        self.img_load()

    def img_load(self):

        self.image = pygame.image.load("./resource/bullet.png")

    def display(self):

        self.screen.blit(self.image, (self.x, self.y))

    def move(self):

        self.y -= 20
