prefacio

Creo que todos han jugado juegos de disparos similares a Airplane Wars, y también disfrutan del placer que brinda la eliminación del objetivo.

Entonces, ¿si usa Python para implementar el juego de guerra de aviones?

Usemos Python para hacer un juego pequeño con todos, no solo puedes sentir la diversión de él, sino también mejorar tu habilidad.

1. Configuración del juego

1. Visualización y configuración de la interfaz del juego

Configuración básica del juego:

• El enemigo dispone de tres tipos de aeronaves, grandes, medianas y pequeñas, divididas en tres velocidades: alta, media y baja;

• El alcance de la viñeta no es pantalla completa, sino aproximadamente el 80 % de la longitud de la pantalla;

• Se necesita 1 bala para destruir un avión pequeño, 8 balas para un avión mediano y 20 balas para un avión grande;

• Cada vez que destruyes un avión pequeño, obtienes 1.000 puntos, los aviones medianos obtienen 6.000 puntos y los aviones grandes obtienen 10.000 puntos;

• Hay un suministro de accesorios aleatorio cada 30 segundos, dividido en dos tipos de accesorios, bomba de pantalla completa y doble bala;

• Las bombas de pantalla completa solo pueden almacenar hasta 3 bombas, y las balas dobles pueden mantener el efecto durante 18 segundos;

• La dificultad del juego aumentará gradualmente según la puntuación, y el aumento de la dificultad se refleja en el aumento del número de aeronaves y la aceleración de la velocidad.

2. Proceso de implementación

1. Nuestro avión

Primero crea un módulo myplane.py para definir nuestro avión:

import pygame

class MyPlane(pygame.sprite.Sprite):
    def __init__(self, bg_size):
        pygame.sprite.Sprite.__init__(self)

        self.image1 = pygame.image.load("images/me1.png").convert_alpha()
        self.image2 = pygame.image.load("images/me2.png").convert_alpha()
        self.destroy_images = []
        self.destroy_images.extend([\
            pygame.image.load("images/me_destroy_1.png").convert_alpha(), \
            pygame.image.load("images/me_destroy_2.png").convert_alpha(), \
            pygame.image.load("images/me_destroy_3.png").convert_alpha(), \
            pygame.image.load("images/me_destroy_4.png").convert_alpha() \
            ])
        self.rect = self.image1.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.rect.left, self.rect.top = \
                        (self.width - self.rect.width) // 2, \
                        self.height - self.rect.height - 60
        self.speed = 10
        self.active = True
        self.invincible = False
        self.mask = pygame.mask.from_surface(self.image1)

    # 分别定义moveUp()、moveDown()、moveLeft()和moveRight()控制我方飞机上、下、左、右移动:

    def moveUp(self):
        if self.rect.top > 0:
            self.rect.top -= self.speed
        else:
            self.rect.top = 0

    def moveDown(self):
        if self.rect.bottom < self.height - 60:
            self.rect.top += self.speed
        else:
            self.rect.bottom = self.height - 60

    def moveLeft(self):
        if self.rect.left > 0:
            self.rect.left -= self.speed
        else:
            self.rect.left = 0

    def moveRight(self):
        if self.rect.right < self.width:
            self.rect.left += self.speed
        else:
            self.rect.right = self.width

    def reset(self):
        self.rect.left, self.rect.top = \
                        (self.width - self.rect.width) // 2, \
                        self.height - self.rect.height - 60
        self.active = True
        self.invincible = True

2. Aviones enemigos

Los aviones enemigos se dividen en tres tamaños: pequeño, mediano y grande. Sus velocidades son rápidas, medias y lentas a su vez. Crea aviones enemigos aleatorios en la parte superior de la interfaz del juego para que no aparezcan en la misma fila. Escriba la definición de la aeronave enemiga en el módulo enemigo.py:

import pygame
from random import *
class SmallEnemy(pygame.sprite.Sprite):
    def __init__(self, bg_size):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load("images/enemy1.png").convert_alpha()
        self.destroy_images = []
        self.destroy_images.extend([ \
            pygame.image.load("images/enemy1_down1.png").convert_alpha(), \
            pygame.image.load("images/enemy1_down2.png").convert_alpha(), \
            pygame.image.load("images/enemy1_down3.png").convert_alpha(), \
            pygame.image.load("images/enemy1_down4.png").convert_alpha() \
            ])
        self.rect = self.image.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.speed = 2
        self.active = True

        self.mask = pygame.mask.from_surface(self.image)

    def move(self):
        if self.rect.top < self.height:

    def reset(self):

class MidEnemy(pygame.sprite.Sprite):
    energy = 8

    def __init__(self, bg_size):

        self.image = pygame.image.load("images/enemy2.png").convert_alpha()
        self.image_hit = pygame.image.load("images/enemy2_hit.png").convert_alpha()
        self.destroy_images = []
        self.destroy_images.extend([ \
            pygame.image.load("images/enemy2_down1.png").convert_alpha(), \
            pygame.image.load("images/enemy2_down2.png").convert_alpha(), \
            pygame.image.load("images/enemy2_down3.png").convert_alpha(), \
            pygame.image.load("images/enemy2_down4.png").convert_alpha() \
            ])
        self.rect = self.image.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.speed = 1
        self.active = True
        self.rect.left, self.rect.top = \
            randint(0, self.width - self.rect.width), \
            randint(-10 * self.height, -self.height)
        self.mask = pygame.mask.from_surface(self.image)
        self.energy = MidEnemy.energy
        self.hit = False

    def move(self):
        if self.rect.top < self.height:
            self.rect.top += self.speed
        else:
            self.reset()

    def reset(self):
        self.active = True
        self.energy = MidEnemy.energy
        self.rect.left, self.rect.top = \
            randint(0, self.width - self.rect.width), \
            randint(-10 * self.height, -self.height)


class BigEnemy(pygame.sprite.Sprite):
    energy = 20

    def __init__(self, bg_size):
        pygame.sprite.Sprite.__init__(self)

        self.image1 = pygame.image.load("images/enemy3_n1.png").convert_alpha()
        self.image2 = pygame.image.load("images/enemy3_n2.png").convert_alpha()
        self.image_hit = pygame.image.load("images/enemy3_hit.png").convert_alpha()
        self.destroy_images = []
        self.destroy_images.extend([ \
            pygame.image.load("images/enemy3_down1.png").convert_alpha(), \
            pygame.image.load("images/enemy3_down2.png").convert_alpha(), \
            pygame.image.load("images/enemy3_down3.png").convert_alpha(), \
            pygame.image.load("images/enemy3_down4.png").convert_alpha(), \
            pygame.image.load("images/enemy3_down5.png").convert_alpha(), \
            pygame.image.load("images/enemy3_down6.png").convert_alpha() \
            ])
        self.rect = self.image1.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.speed = 1
        self.active = True
        self.rect.left, self.rect.top = \
            randint(0, self.width - self.rect.width), \
            randint(-15 * self.height, -5 * self.height)
        self.mask = pygame.mask.from_surface(self.image1)
        self.energy = BigEnemy.energy
        self.hit = False

    def move(self):
        if self.rect.top < self.height:
            self.rect.top += self.speed
        else:
            self.reset()

    def reset(self):
        self.active = True
        self.energy = BigEnemy.energy
        self.rect.left, self.rect.top = \
            randint(0, self.width - self.rect.width), \
            randint(-15 * self.height, -5 * self.height)

3. Definir el arma

Definir balas Hay dos tipos de balas: una es balas ordinarias que solo disparan una bala a la vez, la otra son súper balas emitidas por suministros que pueden disparar dos balas a la vez.

Definimos bullet como un módulo separado bullet.py:

import pygame
class Bullet1(pygame.sprite.Sprite):
    def __init__(self, position):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load("images/bullet1.png").convert_alpha()
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = position
        self.speed = 12
        self.active = False
        self.mask = pygame.mask.from_surface(self.image)

    def move(self):
        self.rect.top -= self.speed

        if self.rect.top < 0:
            self.active = False

    def reset(self, position):
        self.rect.left, self.rect.top = position
        self.active = True


class Bullet2(pygame.sprite.Sprite):
    def __init__(self, position):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load("images/bullet2.png").convert_alpha()
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = position
        self.speed = 14
        self.active = False
        self.mask = pygame.mask.from_surface(self.image)

    def move(self):
        self.rect.top -= self.speed

        if self.rect.top < 0:
            self.active = False

    def reset(self, position):
        self.rect.left, self.rect.top = position
        self.active = True

4. Biblioteca complementaria de armas:

El diseño del juego distribuye aleatoriamente un paquete de suministros cada 30 segundos, que puede ser una súper bala o una bomba de pantalla completa. El paquete de suministro tiene su propia imagen y trayectoria, defina un módulo supply.py: 

import pygame
from random import *


class Bullet_Supply(pygame.sprite.Sprite):
    def __init__(self, bg_size):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load("images/bullet_supply.png").convert_alpha()
        self.rect = self.image.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.rect.left, self.rect.bottom = \
            randint(0, self.width - self.rect.width), -100
        self.speed = 5
        self.active = False
        self.mask = pygame.mask.from_surface(self.image)

    def move(self):
        if self.rect.top < self.height:
            self.rect.top += self.speed
        else:
            self.active = False

    def reset(self):
        self.active = True
        self.rect.left, self.rect.bottom = \
            randint(0, self.width - self.rect.width), -100


class Bomb_Supply(pygame.sprite.Sprite):
    def __init__(self, bg_size):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load("images/bomb_supply.png").convert_alpha()
        self.rect = self.image.get_rect()
        self.width, self.height = bg_size[0], bg_size[1]
        self.rect.left, self.rect.bottom = \
            randint(0, self.width - self.rect.width), -100
        self.speed = 5
        self.active = False
        self.mask = pygame.mask.from_surface(self.image)

    def move(self):
        if self.rect.top < self.height:
            self.rect.top += self.speed
        else:
            self.active = False

    def reset(self):
        self.active = True
        self.rect.left, self.rect.bottom = \
            randint(0, self.width - self.rect.width), -100
