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
