仕組み
ボタンを押すとコマンドブロックが webhooks execute post-like x を実行(x部分は任意の名前)
SimpleWebhooks が http://localhost:5000/ に名前をPOST
localhostで動いてるFlaskがリクエストを受け取ってRCONでコマンド実行
command = f"data get storage likes {name}"
storageからいいねの数を取得
1増やす
command = f"data modify storage likes {name} set value {value}"
増やした値をstorageに書き込む
command = f"hd setLine likes_{name} 1 LIKE: {value}"
Holographic Displaysを更新
HDの名前は likes_x という形になってる想定


SimpleWebhooks/config.yaml
post-like: url: http://localhost:5000/ json: name: "{COMMAND_PARAM_1}"

server.py
from flask import Flask, request from aiomcrcon import Client import asyncio import re import threading from secret import PASSWORD, HOST, PORT app = Flask(__name__) client = Client(HOST, PORT, PASSWORD) def create_app(): return app async def update_likes(name): await client.connect() command = f"data get storage likes {name}" response = await client.send_cmd(command) if "Found no elements matching" in response[0]: value = 0 else: value = int(re.search("\d+", response[0]).group()) value += 1 command = f"data modify storage likes {name} set value {value}" response = await client.send_cmd(command) command = f"hd setLine likes_{name} 1 LIKE: {value}" response = await client.send_cmd(command) await client.close() @app.route('/', methods=['GET', 'POST']) def root(): if request.method == "GET": return "OK" else: name = request.json["name"] x = threading.Thread(target=lambda: asyncio.run(update_likes(name)), args=()).start() return "OK"

ハマりどころ
Webhookに対してRCONを実行する前にOKを返す必要がある
RCONパケットを送っても実行されずタイムアウトする
おそらくWebhookコマンドがロックをつかんでいる
そこでスレッドを作る形にした
