python趣味小游戏之多彩小球球

用PYTHON写出多彩小球球，编写这个程序主要是练习**list[]**的运用

#coding = utf - 8
import pgzrun
import random
height = 600  #屏幕的高
weith = 800   #屏幕的宽
balls = []
for i in range(100):
    x = random.randint(100,weith-100)      #小球横坐标x
    y = random.randint(100,height-100)     #小球纵坐标y
    speed_x = random.randint(1,5)          #小球横向速度
    speed_y = random.randint(1,5)           #小球纵向速度
    r = random.randint(5,50)                #小球半径
    color1 = random.randint(10,255)         #小球3个颜色分量
    color2 = random.randint(10,255)
    color3 = random.randint(10,255)
    ball = [x,y,speed_x,speed_y,r,color1,color2,color3]  #小球列表信息
    balls.append(ball)                     #将第i个小球的信息添加的ball中

def draw():                     #绘制模块
    screen.fill((255,255,255))  #白色背景
    for ball in balls:          #绘制所有的球
        screen.draw.filled_circle((ball[0],ball[1]),ball[5],(ball[-1],ball[-2],ball[-3]))

def update():                       #更新模块
    for ball in balls:
        ball[0] = ball[0] + ball[2]     #更新x坐标
        ball[1] = ball[1] + ball[3]     #更新y坐标
        if ball[0] >= weith - ball[5] or ball[0] <= ball[5]:   #判断左右边界，x方向速度反向
            ball[2] = -ball[2]
        if ball[1] >= height - ball[5] or ball[1] <= ball[5]:
            ball[3] = -ball[3]

pgzrun.go()

用鼠标增加互动操作。
