这是我第一次发布文章,就爱闲的没事整点活玩,写的不好还请见谅
使用的语言是Python,因为实在是太方便了o(TヘTo)
对了,要是懒得看代码思想直接跳到完整代码就彳亍
想必大家都听说过原神吧,是米哈游开发的大世界探索游戏。大学一放假就太闲了,于是就用python写了个模拟原神抽卡的程序,其实星铁也适用这个机制
大家可以用它来试试运气,我在测试的时候一次出了三金,两个纳西妲一个琴(炫耀)[为什么我游戏中就没这运气,天天大保底,气死了]
好的,那么废话不多说,我们先说一下原理
根据我从网上和官方给出的概率浏览获得的信息:
180抽大保底,90抽小保底
五星中奖概率为0.6%
四星角色概率为2.55%
其余的三星概率是96.85%
大保底小报底各占50%
五星概率会从第74抽开始逐渐提高6%
概率 | 抽卡次数i |
---|---|
0.006 | (i<=73) |
0.006 + 0.06(i - 73) | (74<=i<=89) |
1 | (i=90) |
毕竟是抽卡,怎么能少了random
然后这个os是新建文件夹用的
用来保存你的抽卡记录,还有创建你的卡池
import os
import random
其实简单说说就是,先加入9685个蓝色,然后加入255个紫色,再加入6个金色,然后打乱
# 初始化抽卡的概率
def rate_initialization():
rate_list.extend(['蓝' for temp in range(9685)]) # 蓝色概率是96.85%
rate_list.extend(['紫' for temp in range(255)]) # 紫色概率是2.55%
rate_list.extend(['金' for temp in range(60)]) # 金色概率是0.6%
random.shuffle(rate_list) # 打乱这个列表
其实就是74抽之后,每次把60个蓝色去掉,然后随机插入60个金色
啊,这个踹他的原因就是怕一开始初始化蓝色数量不够,其实没啥用,可以删掉
# 74抽之后增加概率
def rate_add():
try:
for _ in range(60):
rate_list.remove('蓝')
rate_list.insert(random.randint(0, len(rate_list) - 1), '金')
except ValueError:
print('程序异常,概率增加异常')
exit()
有点小长,说简单点其实就是检测是否有保底这个文本文档,如果有就读一下,没有就创建并写入false表示是小报底,true是大保底。如果是false就在up和常驻中随机抽取,抽到up还是false,抽到常驻变成true,就这么个原理
# 大保底还是小保底 def guarantees(): try: with open('recording\\isGuarantees.txt', 'r', encoding='utf-8') as file: if file.read() == 'true': certainly = True else: certainly = False except BaseException: with open('recording\\isGuarantees.txt', 'w+', encoding='utf-8') as file: file.write('false') with open('recording\\isGuarantees.txt', 'r', encoding='utf-8') as file: if file.read() == 'true': certainly = True else: certainly = False if certainly: with open('recording\\isGuarantees.txt', 'w+', encoding='utf-8') as file: file.write('false') return True else: res = random.choice(['up', 'resident']) if res == 'up': with open('recording\\isGuarantees.txt', 'w+', encoding='utf-8') as file: file.write('false') return True else: with open('recording\\isGuarantees.txt', 'w+', encoding='utf-8') as file: file.write('true') return False
其实注释都说了,不存在就新建一个,存在就拉倒
# 创建一个文件夹在同一个目录下
def mkdir(path):
folder = os.path.exists(path)
if not folder: # 判断文件夹是否存在
os.makedirs(path) # 不存在就新建一个
这个其实和上面的保底一样的,找不到文件就新建一个,然后初始化为0
# 抽卡次数读取
def read_times():
try:
with open('recording\\times.txt', 'r', encoding='utf-8') as file:
number = int(file.read())
return number
except BaseException:
with open('recording\\times.txt', 'w+', encoding='utf-8') as file:
file.write('0')
return 0
这就是为什么上面的保底返回的是True和False,出了就append一个up角色,歪了就append一个常驻的角色上去
# 出金了
def gold():
rate_initialization()
record_times(0)
if guarantees():
res_list.append(up)
return '出货了!!!!!'
else:
res_list.append(random.choice(fiveStar))
return '哇!金色传。。。歪了。。。'
第十抽必是紫色,如果不满10抽出了紫色,那么记录则会清零,这是记录和读取的函数
# 记录紫色保底,10抽必出紫色
def record_rare(number):
with open('recording\\rare.txt', 'w+', encoding='utf-8') as file:
file.write(str(number))
# 读取紫色保底
def read_rare():
try:
with open('recording\\rare.txt', 'r', encoding='utf-8') as file:
return int(file.read())
except BaseException:
with open('recording\\rare.txt', 'w+', encoding='utf-8') as file:
file.write('0')
return 0
其实就是把刚刚的方法或者叫函数也行,统合到了一起初始化卡池,读取,打乱,因为每次抽卡都会有一个动画告诉你是蓝天白云还是出货了,还是只有紫色,所以加了一个描述的打印输出。然后每次出金色都会重置概率,重新初始化,其余的就是照着我写的代码思想写的,其实也不是很难
mkdir('卡池') mkdir('recording') while True: try: with open('卡池\\up.txt', 'r', encoding='utf-8') as tempFile: up = tempFile.read() with open('卡池\\fiveStar.txt', 'r', encoding='utf-8') as tempFile: fiveStar = tempFile.read().split(sep=' ') with open('卡池\\fourStar.txt', 'r', encoding='utf-8') as tempFile: fourStar = tempFile.read().split(sep=' ') with open('卡池\\threeStar.txt', 'r', encoding='utf-8') as tempFile: threeStar = tempFile.read().split(sep=' ') break except BaseException: print('你好,欢迎使用本模拟器,我在上面帮你创建了几文件夹,在里面填入卡池的东西就好了,用空格隔开') with open('卡池\\up.txt', 'w+', encoding='utf-8'): pass with open('卡池\\fiveStar.txt', 'w+', encoding='utf-8'): pass with open('卡池\\fourStar.txt', 'w+', encoding='utf-8'): pass with open('卡池\\threeStar.txt', 'w+', encoding='utf-8'): pass input('填好了就回个车') rate_list = list() rate_initialization() while True: try: wish = int(input('1、单抽 2、十连抽 3、退出\n请输入:')) except ValueError: print('你这输入的啥玩意') continue if wish == 1: count = 1 elif wish == 2: count = 10 elif wish == 3: break else: print('奇奇怪怪的数字') continue res_list = [] result_report = '蓝天白云' temp_list = [random.choice(rate_list) for _ in range(count)] flag = False for character_rank in temp_list: if 73 <= read_times() <= 88: rate_add() elif read_times() >= 89: result_report = gold() continue record_times(read_times() + 1) if character_rank == '蓝': record_rare(read_rare() + 1) if read_rare() >= 10: if not flag: result_report = '出了个紫色' record_rare(0) res_list.append(random.choice(fourStar)) continue res_list.append(random.choice(threeStar)) elif character_rank == '紫': if not flag: result_report = '出了个紫色' record_rare(0) res_list.append(random.choice(fourStar)) elif character_rank == '金': flag = True result_report = gold() print(result_report) print(' '.join(res_list)) # recode_gacha() print('==================================================')

记得要在卡池里放东西,因为这个为了灵活控制卡池,比如新增什么常驻,四星角色,或者三星武器什么的,用的读取文本文档的方式来进行卡池数据的储存的,虽然数据库也可以,但是多少有点大材小用了。
我这里给出一些我写好的用例吧,记得角色和角色,或者是武器和武器之间要用空格隔开,因为我这个是split(sep=’ ')劈分的是空格。我这里写了部分4星和目前5星常驻的角色,三星实在太多了,写不动了,这里我放出来
up.txt
就写一个限定角色就行,我写的纳西妲,因为我最喜欢纳西妲了

那么就到这里吧,感谢能读到这,我是喜欢整活的小狐,每天整点活玩就是我的乐趣。想想下次能玩点什么新花样,如果觉得有意思的话,还请点一个小小的赞。目前在忙项目,只能实现简单的逻辑,交互什么的下次一定。有时间再写到Django里。
