python烟花表白源代码

在 Python 中创建一个简单的烟花表白效果可以使用 Pygame 库。

python
import pygame
import sys
import random
import math

# 初始化 Pygame
pygame.init()

# 设置屏幕大小
width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("烟花表白")

# 定义颜色
white = (255, 255, 255)
red = (255, 0, 0)

# 定义烟花类
class Firework:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
        self.radius = 2
        self.speed = random.uniform(1, 5)
        self.angle = random.uniform(0, 2 * math.pi)

    def move(self):
        self.x += self.speed * math.cos(self.angle)
        self.y += self.speed * math.sin(self.angle)
        self.speed -= 0.1
        self.radius += 0.1

    def draw(self):
        pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), int(self.radius))

# 主循环
fireworks = []
clock = pygame.time.Clock()
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill(white)

    # 生成烟花
    if random.randint(1, 100) < 2:
        fireworks.append(Firework(random.randint(100, width - 100), height))

    # 更新和绘制烟花
    for firework in fireworks:
        firework.move()
        firework.draw()

    # 移除消失的烟花
    fireworks = [fw for fw in fireworks if fw.radius < 50]

    pygame.display.flip()
    clock.tick(60)

pygame.quit()
sys.exit()

请确保你的环境中安装了 Pygame。可以使用

bash
pip install pygame

运行上述代码后，窗口将打开，并且屏幕上会出现随机生成的烟花效果。

如果你想在烟花爆炸的时候显示一些特殊的信息，例如表白文字，你可以在Firework类中添加一些属性，以在烟花达到一定半径时显示该信息。

python
import pygame
import sys
import random
import math

pygame.init()

width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("烟花表白")

white = (255, 255, 255)
red = (255, 0, 0)

class Firework:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
        self.radius = 2
        self.speed = random.uniform(1, 5)
        self.angle = random.uniform(0, 2 * math.pi)
        self.message = "I Love You!" if random.randint(1, 10) == 1 else None

    def move(self):
        self.x += self.speed * math.cos(self.angle)
        self.y += self.speed * math.sin(self.angle)
        self.speed -= 0.1
        self.radius += 0.1

    def draw(self):
        pygame.draw.circle(screen, self.color, (int(self.x), int(self.y)), int(self.radius))
        if self.message and self.radius > 20:
            font = pygame.font.Font(None, 36)
            text = font.render(self.message, True, red)
            text_rect = text.get_rect(center=(width // 2, height // 2))
            screen.blit(text, text_rect)

fireworks = []
clock = pygame.time.Clock()
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill(white)

    if random.randint(1, 100) < 2:
        fireworks.append(Firework(random.randint(100, width - 100), height))

    for firework in fireworks:
        firework.move()
        firework.draw()

    fireworks = [fw for fw in fireworks if fw.radius < 50]

    pygame.display.flip()
    clock.tick(60)

pygame.quit()
sys.exit()

这个例子中，当烟花的半径超过20时，将显示一个"I Love You!"的信息。你可以根据需要调整显示信息的条件和内容。希望这能满足你的需求！
