飞机大战如何飞机一次发射5发并排子弹，如何修改代码

FishC · 发表于 2024-3-24 14:12:36

要实现飞机一次发射5发并排的子弹，可以对子弹的位置进行适当的偏移。以下是一个简单的示例代码：

import pygame
from pygame.locals import *
def main():
# 初始化
pygame.init()
# 设置窗口大小和标题
screen_width, screen_height = 480, 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("飞机大战")
# 加载飞机图片
plane_img = pygame.image.load("plane.png")
plane_rect = plane_img.get_rect()
plane_rect.topleft = (screen_width // 2 - plane_rect.width // 2, screen_height - plane_rect.height)
# 加载子弹图片
bullet_img = pygame.image.load("bullet.png")
bullet_rect = bullet_img.get_rect()
# 定义子弹列表
bullets = []
while True:
# 绘制背景
screen.fill((255, 255, 255))
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
exit()
# 按下空格键发射子弹
if event.type == KEYDOWN and event.key == K_SPACE:
# 创建5颗子弹，并设置初始位置
for i in range(5):
bullet = {'rect': bullet_rect.copy(),
'x': plane_rect.centerx - bullet_rect.width // 2 + (i - 2) * 20,
'y': plane_rect.top - bullet_rect.height}
bullets.append(bullet)
# 移动子弹
for bullet in bullets:
bullet['y'] -= 5
# 绘制飞机和子弹
screen.blit(plane_img, plane_rect)
for bullet in bullets:
screen.blit(bullet_img, (bullet['x'], bullet['y']))
# 移除超出屏幕的子弹
bullets = [bullet for bullet in bullets if bullet['y'] > -bullet_rect.height]
# 更新屏幕显示
pygame.display.update()
if __name__ == '__main__':
main()

复制代码

在上述代码中，我们通过`for`循环创建了5颗子弹，并根据飞机的位置和子弹宽度进行了适当的偏移，将子弹添加到了`bullets`列表中。然后，我们使用`for`循环遍历并移动子弹，绘制飞机和子弹，并删除超出屏幕的子弹。最后，更新屏幕显示。

请注意，以上代码只是一个简单的示例，您可以根据自己的需求进行修改和扩展。例如，可以为子弹添加碰撞检测、设置不同的速度等。

要实现飞机一次发射5发并排的子弹，需要对代码中的子弹生成部分进行适当修改。以下是修改后的代码示例：

# 生成普通子弹
bullet1 = []
bullet1_index = 0
BULLET1_NUM = 8
for i in range(BULLET1_NUM // 4):
bullet1.append(bullet.Bullet1((me.rect.centerx - 33, me.rect.centery)))
bullet1.append(bullet.Bullet1((me.rect.centerx - 13, me.rect.centery)))
bullet1.append(bullet.Bullet1((me.rect.centerx + 13, me.rect.centery)))
bullet1.append(bullet.Bullet1((me.rect.centerx + 33, me.rect.centery)))
while running:
# ...
if life_num and not paused:
# ...
key_pressed = pygame.key.get_pressed()
if key_pressed[K_SPACE]:
if bullet1[bullet1_index].active is False:
bullet_sound.play()
bullet1[bullet1_index].reset((me.rect.centerx - 33, me.rect.centery))
bullet1[(bullet1_index + 1) % BULLET1_NUM].reset((me.rect.centerx - 13, me.rect.centery))
bullet1[(bullet1_index + 2) % BULLET1_NUM].reset((me.rect.centerx + 13, me.rect.centery))
bullet1[(bullet1_index + 3) % BULLET1_NUM].reset((me.rect.centerx + 33, me.rect.centery))
bullet1_index = (bullet1_index + 4) % BULLET1_NUM
# ...
# ...

复制代码

在上述代码中，我们通过修改子弹生成部分的代码，使用了一个循环生成了4颗子弹，并对子弹的初始位置进行了四个不同的偏移。然后，在主循环中添加了按下空格键发射子弹的逻辑，当一颗子弹不处于活动状态时，设置其新的初始位置，并更新索引。这样，飞机每次按下空格键就会发射5发并排的子弹。

请注意，上述代码是在原有代码基础上的修改示例，您需要将其与原有代码进行合并。同时，如果需要使用其他类型的子弹，可以类似地进行修改和扩展。
