Pythonで書くシンプルなガチャロジック

Last updated at Posted at 2020-05-03

内容

アイテム別に重み付けをしてn連ガチャを行います

パラメータ

パラメータとして以下の物を用意

# 抽選対象のアイテムIDと重みのdictionary
item_dic = {"id_1":1,"id_2":5,"id_3":14,"id_4":30,"id_5":50}
# 抽選回数
times = 11

ガチャ処理の関数

import random
def gacha(item_dic, times):
    total_weight = 0
    for value in item_dic.values():
        total_weight += value

    results = []
    for i in range(times):
        results.append(lottery(item_dic,total_weight))

    return results

def lottery(item_dic, total_weight):
    score = random.randint(1,total_weight)
    range_max = 0
    for item_key, weight in item_dic.items():
        range_max += weight
        if score <= range_max:
            return item_key         

ガチャを実行

item_list = gacha(item_dic, times)

もう少し綺麗な書き方があると思いますが、とりあえず。
