相信很多朋友都看过黑客帝国这部电影,并且对里边矩阵的绿色弹幕效果有深刻印象,这个效果其实只做起来特别的简单,今天我们就用python来实现以下,
只需要使用一个库叫做pygame
当然首先需要安装这个库
pip install pygame
然后就是写代码了:
import pygame
import random
import sys
# 初始化pygame
pygame.init()
# 获取屏幕分辨率
info = pygame.display.Info()
width, height = info.current_w, info.current_h
# 创建全屏窗口
screen = pygame.display.set_mode((width, height), pygame.FULLSCREEN)
pygame.display.set_caption("黑客帝国矩阵")
# 扩展字符集,包括日文和韩文
characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()-_=+[]{}|;:,.<>?/`~" + \
"あいうえおかきくけこさしすせそたちつてとなにぬねのはひふへほまみむめもやゆよらりるれろわをんがぎぐげござじずぜぞだぢづでどばびぶべぼぱぴぷぺぽ" + \
"가나다라마바사아자차카타파하거너더러머버서어저처커터퍼허"
# 选择一个支持多语言的字体
font = pygame.font.Font(None, 36) # 选择默认字体,如果需要特定字体,请提供字体文件路径
# 获取单个字符的宽度
char_width, char_height = font.size('A')
# 创建字符列
class Column:
def __init__(self, x):
self.x = x
self.y = random.randint(-height, 0)
self.speed = random.randint(2, 6) # 初始速度
self.char = random.choice(characters)
def update(self, speed_multiplier):
self.y += self.speed * speed_multiplier
if self.y > height:
self.y = -char_height
self.char = random.choice(characters)
def draw(self, surface):
text_surface = font.render(self.char, True, (0, 255, 0)) # 绿色字符
surface.blit(text_surface, (self.x, self.y))
# 创建多列字符
columns = [Column(x) for x in range(0, width, char_width // 2)] # 增加列数
# 主循环
clock = pygame.time.Clock()
running = True
start_time = pygame.time.get_ticks() # 记录开始时间
target_speed_multiplier = 5.0 # 目标速度倍数
speed_multiplier = 1.0 # 当前速度倍数
while running:
current_time = pygame.time.get_ticks()
elapsed_time = (current_time - start_time) / 1000.0 # 转换为秒
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE: # 按ESC键退出
running = False
# 更新速度倍数
if elapsed_time < 10.0:
speed_multiplier = 1.0 + (target_speed_multiplier - 1.0) * (elapsed_time / 10.0)
else:
speed_multiplier = target_speed_multiplier
# 更新每一列
for column in columns:
column.update(speed_multiplier)
# 绘制背景
screen.fill((0, 0, 0)) # 黑色背景
# 绘制每一列
for column in columns:
column.draw(screen)
# 更新屏幕
pygame.display.flip()
clock.tick(60) # 提高帧率到60fps
# 退出pygame
pygame.quit()
sys.exit()
