煙花

第1步：模塊導(dǎo)入

第2步：定義相關(guān)初始

win（窗口的w=寬，h=高）

WIN_W = 2200WIN_H = 1300

定義時(shí)間、顯示、頻率

煙花顏色列表，下面隨機(jī)抽出

color_list = [                [255, 50, 50],                [50, 255, 50],                [50, 50, 255],                [255, 255, 50],                [255, 50, 255],                [50, 255, 255],                [255, 255, 255]             ]

初始化pygame和音樂mixer

創(chuàng)建一個(gè)窗口,pygame.RESIZABLE窗口大小可調(diào)節(jié)和標(biāo)題

screen = pygame.display.set_mode((WIN_W, WIN_H),pygame.RESIZABLE, 32)pygame.display.set_caption('五彩煙花大放送')

背景音樂，可自定義

Fireworks=煙花，定義主類

class Fireworks():    is_show = False    x, y = 0, 0    vy = 0    p_list = []    color = [0, 0, 0]    v = 0    def __init__(self, x, y, vy, n=300, color=[0, 255, 0], v=10):        self.x = x        self.y = y        self.vy = vy        self.color = color        self.v = v        for i in range(n):            self.p_list.append([random.random() * 2 * math.pi, 0, v * math.pow(random.random(), 1 / 3)])    def again(self):        self.is_show = True        self.x = random.randint(WIN_W // 2 - 350, WIN_W // 2 + 350)        self.y = random.randint(int(WIN_H / 2), int(WIN_H * 3 / 5))        self.vy = -40 * (random.random() * 0.4 + 0.8) - self.vy * 0.2        self.color = color_list[random.randint(0, len(color_list) - 1)].copy()        n = len(self.p_list)        self.p_list = []        for i in range(n):            self.p_list.append([random.random() * 2 * math.pi, 0, self.v * math.pow(random.random(), 1 / 3)])    def run(self):        global show_n        for p in self.p_list:            p[1] = p[1] + (random.random() * 0.6 + 0.7) * p[2]            p[2] = p[2] * 0.97            if p[2] < 1.2:                self.color[0] *= 0.9999                self.color[1] *= 0.9999                self.color[2] *= 0.9999            if max(self.color) < 10 or self.y>WIN_H+p[1]:                show_n -= 1                self.is_show = False                break        self.vy += 10 * t1        self.y += self.vy * t1

煙花列表

煙花放送的主循環(huán)：
