粒子光效圣诞树代码python

以下是一个使用Python实现粒子光效圣诞树的代码示例：

import random
import time

# 设置屏幕大小
screen_width = 80
screen_height = 20

# 定义树的高度和宽度
tree_height = 10
tree_width = 7

# 定义树干的高度和宽度
trunk_height = 3
trunk_width = 3

# 定义粒子的数量
num_particles = 100

# 定义粒子的符号
particle_char = "*"

# 定义粒子的颜色
particle_colors = ["\033[91m", "\033[92m", "\033[93m", "\033[94m", "\033[95m", "\033[96m"]

# 清空屏幕
def clear_screen():
    print("\033c", end="")

# 绘制树
def draw_tree():
    for i in range(tree_height):
        spaces = " " * (screen_width // 2 - tree_width // 2 - i)
        stars = "*" * (tree_width + 2 * i)
        print(spaces + stars)

# 绘制树干
def draw_trunk():
    for i in range(trunk_height):
        spaces = " " * (screen_width // 2 - trunk_width // 2)
        trunk = "*" * trunk_width
        print(spaces + trunk)

# 绘制粒子
def draw_particles():
    particles = []
    for _ in range(num_particles):
        x = random.randint(0, screen_width - 1)
        y = random.randint(0, screen_height - 1)
        color = random.choice(particle_colors)
        particles.append((x, y, color))
    
    while True:
        clear_screen()
        for particle in particles:
            x, y, color = particle
            print("\033[{};{}H{}{}".format(y, x, color, particle_char))
            particle = (x, y + 1, color)
            if y >= screen_height - 1:
                particle = (x, 0, color)
            particles.remove(particle)
            particles.append(particle)
        time.sleep(0.1)

# 主函数
def main():
    clear_screen()
    draw_tree()
    draw_trunk()
    draw_particles()

# 运行主函数
if __name__ == "__main__":
    main()
