用于在游戏中为多名玩家添加积分的代码

# 导入必要的库
import pymongo

# 连接数据库
client = pymongo.MongoClient("mongodb://localhost:27017/")
db = client["game_database"]
collection = db["player_scores"]

# 定义函数来为玩家添加积分
def add_score(player_id, score):
    # 检查玩家是否存在
    player = collection.find_one({"player_id": player_id})
    if player:
        # 更新玩家的积分
        new_score = player["score"] + score
        collection.update_one({"player_id": player_id}, {"$set": {"score": new_score}})
        print("玩家 {} 的积分已更新为 {}".format(player_id, new_score))
    else:
        # 创建新的玩家记录
        player_data = {"player_id": player_id, "score": score}
        collection.insert_one(player_data)
        print("已为玩家 {} 创建新的积分记录".format(player_id))

# 测试代码
add_score("player1", 10)
add_score("player2", 20)
add_score("player1", 5)
