躲避雪球的小游戏 如何随机生成多个雪球

Question

新入门python

尝试做小游戏练手

想实现以下功能：

生成世界框架 √
生成玩家 √
玩家移动方式 √
随机位置生成单个雪球 √
雪球移动方式 √

随机位置生成多个雪球 ×
积分面板 ×

两个打“×”的功能现在还没有实现
请朋友们帮忙解答一下
谢谢

import numpy as np 
import cv2 
import random

WIDTH = 20
HEIGHT = 10

player_position = 0
ice_position = [0, random.randint(0, WIDTH - 1)]

while True:
    #init world
    arr = np.zeros((HEIGHT, WIDTH)).astype(np.uint8)
    #populate player
    arr[-1, player_position] = 255
    #populate ice
    arr[ice_position[0], ice_position[1]] = 100
    #show world
    arr = cv2.resize(arr, (WIDTH * 50, HEIGHT * 50), interpolation = cv2.INTER_NEAREST)


    cv2.imshow("game", arr)  #show image
    k = cv2.waitKey(100) # wait for 100ms

    # make the ice fall
    ice_position[0] += 1

    if ice_position[0] != HEIGHT:
        arr[ice_position[0], ice_position[1]] = 100
    else:
        ice_position = [0, random.randint(0, WIDTH - 1)]
                

    # player action
    if k == ord("d"):            
        if player_position < WIDTH - 1:
            player_position += 1

    if k == ord("a"): 
        if player_position > 0:
            player_position -= 1       
        

    if k == ord("q"):
        exit()

    
    if ice_position == [HEIGHT-1, player_position]:
        exit()

你会生成单个，那你循环一下，调用几次不就生成几个吗
