一、项目简介这是一个用Python语言绘制的动态爱心图案，你动了吗？编译器：PyCharm Community Edition二、运行截图

三、代码思路1、引入库文件random、math、tkinterimport randomfrom math import sin, cos, pi, logfrom tkinter import 2、设置画布CANVAS_WIDTH = 800 画布长600CANVAS_CENTER_X = CANVAS_WIDTH / 2CANVAS_CENTER_Y = CANVAS_HEIGHT / 2IMAGE_ENLARGE = 11HEART_COLOR = "ff2121 这个参数... dx = ratio force (x - CANVAS_CENTER_X) dy = ratio force (y - CANVAS_CENTER_Y) return x - dx, y - dy6、定义曲线函数和跳动周期def curve(p): return 5 (2 sin(4 p)) / (2 pi)7、爱心的类class Heart: def init(self, generate_frame=20): self._points = set() 边缘扩散效果点坐标集合 self._center_diffusion_points = set() 每帧动态点坐标 self.build(2000) self.random_halo = 1000 self.generate_frame = generate_frame for frame in range(generateframe): self.calc(frame) def build(self, number): for in range(number): t = random.uniform(0, 2 pi) x, y = heart_function(t) self._points.add((x, y)) for _x, _y in list(self.points): for in range(3): x, y = scatter_inside(_x, _y, 0.05) self._edge_diffusion_points.add((x, y)) point_list = list(self.points) for in range(4000): x, y = random.choice(point_list) x, y = scatter_inside(x, y, 0.17) self._center_diffusion_points.add((x, y))8、@classmethod 装饰类方法@staticmethod def calc_position(x, y, ratio): force = 1 / (((x - CANVAS_CENTER_X) 2 + (y - CANVAS_CENTER_Y) 2) 0.520) 圆滑的周期的缩放比例 halo_radius = int(4 + 6 (1 + curve(generate_frame / 10 pi))) halo_number = int(3000 + 4000 abs(curve(generate_frame / 10 pi) 2)) all_points = [] heart_halopoint = set() for in range(halo_number): t = random.uniform(0, 2 * pi) x, y = heart_function(t, shrink_ratio=11.6) x, y = shrink(x, y, halo_radius) if (x, y) not in heart_halo_point: heart_halo_point.add((x, y)) x += random.randint(-14, 14) y += random.randint(-14, 14) size = random.choice((1, 2, 2)) all_points.append((x, y, size)) for x, y in self._points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 3) all_points.append((x, y, size)) for x, y in self._edge_diffusion_points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 2) all_points.append((x, y, size)) for x, y in self._center_diffusion_points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 2) all_points.append((x, y, size)) self.all_points[generate_frame] = all_points def render(self, render_canvas, render_frame): for x, y, size in self.all_points[render_frame % self.generate_frame]: render_canvas.create_rectangle(x, y, x + size, y + size, width=0, fill=HEART_COLOR) def draw(main: Tk, render_canvas: Canvas, render_heart: Heart, render_frame=0): render_canvas.delete('all') render_heart.render(render_canvas, render_frame) main.after(160, draw, main, render_canvas, render_heart, render_frame + 1) if name == 'main': root = Tk() # 一个Tk root.title("dotcpp.com") canvas = Canvas(root, bg='black', height=CANVAS_HEIGHT, width=CANVAS_WIDTH) canvas.pack() heart = Heart() draw(root, canvas, heart) root.mainloop()
