avant-propos

Je pense que tout le monde a joué à des jeux de tir similaires à Airplane Wars, et ils apprécient également le plaisir apporté par l'élimination de la cible.

Donc, si vous utilisez Python pour implémenter le jeu de guerre d'avion ?

Utilisons Python pour créer un petit jeu avec tout le monde, non seulement vous pourrez en ressentir le plaisir, mais aussi améliorer vos capacités.

1. Paramètres du jeu

1. Affichage et réglage de l'interface de jeu

Paramètres de base du jeu :

  • L'ennemi dispose de trois types d'avions, gros, moyens et petits, répartis en trois vitesses : haute, moyenne et basse ;

  • La portée de la balle n'est pas en plein écran, mais environ 80 % de la longueur de l'écran ;

  • Il faut 1 balle pour détruire un petit avion, 8 balles pour un avion moyen et 20 balles pour un gros avion ;

  • Chaque fois que vous détruisez un petit avion, vous obtenez 1 000 points, les avions moyens 6 000 points et les gros avions 10 000 points ;

  • Il y a une alimentation aléatoire d'accessoires toutes les 30 secondes, divisée en deux types d'accessoires, une bombe plein écran et une double balle;

  • Les bombes en plein écran ne peuvent stocker que jusqu'à 3 bombes, et les doubles balles peuvent maintenir l'effet pendant 18 secondes ;

  • La difficulté du jeu augmentera progressivement en fonction du score, et l'augmentation de la difficulté se traduit par l'augmentation du nombre d'avions et l'accélération de la vitesse.

2. Processus de mise en œuvre

1. Nos avions

Créez d'abord un module myplane.py pour définir notre avion :


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. Avions ennemis

Les avions ennemis sont divisés en trois tailles : petit, moyen et grand. Leurs vitesses sont tour à tour rapides, moyennes et lentes. Créez des avions ennemis aléatoires en haut de l'interface de jeu afin qu'ils n'apparaissent pas dans la même ligne. Écrivez la définition de l'avion ennemi dans le module ennemi.py :


import pygame

        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(), \

    def move(self):

    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.speed = 1
        self.active = True
        self.rect.left, self.rect.top = \

            randint(-15 * self.height, -5 * self.height)

        self.energy = BigEnemy.energy
        self.hit = False

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

    def reset(self):

            randint(0, self.width - self.rect.width), \
            randint(-15 * self.height, -5 * self.height)

3. Définir l'arme

Définir les balles. Il existe deux types de balles : l'une est une balle ordinaire qui ne tire qu'une seule balle à la fois ; l'autre est une super balle émise par des fournitures qui peuvent tirer deux balles à la fois.

Nous définissons bullet comme un module séparé 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. Bibliothèque supplémentaire d'armes :

La conception du jeu distribue au hasard un paquet de fournitures toutes les 30 secondes, qui peut être une super balle ou une bombe en plein écran. Le package supply a sa propre image et sa propre trajectoire, définissez un module 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
