Topic: Installer Tamper Monkey pour utiliser Scratch avec Warcraft

[EloiStree]

Installation

Étapes d'installation :

1. Installez Opera GX ou Chrome.
2. Installez Tampermonkey.
3. Copiez le code "Scratch to Local Websocket".
4. Créez un projet Scratch avec une variable wsvar requet.
5. Installez Python.
6. Téléchargez et lancez le serveur local.
7. Téléchargez et exécutez le code "Entier à Warcraft".
8. Vous êtes prêt(e) 🏁😁
9. Testez que tout fonctionne avec le projet suivant :
   • Projet Scratch
   • https://scratch.mit.edu/projects/1061213031

Source: https://github.com/EloiStree/2024_05_10_TamperMonkeyToRsaTunnelingIID/tree/main/ScratchToLocalWebsocket

Ce script convertit toutes les variables commençant par wsvar en entiers, puis les transmet du site Scratch à une application locale qui fonctionne comme un serveur Python.

/*
What this code do ?
This code overlook at the HTML code when you are on https://scratch.mit.edu/projects/*
It searches about the HTML of a variable display in the scratch game that are a HTML Div code.
The div Id are
- name: .monitor_label_ci1ok
- value: .monitor_value_3Yexa

It add the key value in a dictionary if the value changed only to avoid spam when send outside of the script.

With the help of a unsecure websocket client it send the value as a integer converted to 4 bytes in little format.
To use this script you need to recover it with a websocket server of your own and turn back the 4 bytes to integer.

Grâce à ce client web dans le navigateur, on peut rediriger les messages vers un serveur UDP, disponible dans tous les langages de programmation.

import socket

server_websocket_port= 7072
target_udp_ip = "127.0.0.1"
target_udp_port = 7073

async def handler(websocket, path):
    byte_counter = 0
    while True:
            global target_port
            data = await websocket.recv()
            try:
                udp_socket.sendto(data, (target_udp_ip, target_udp_port))
                byte_counter += 8 + len(data)
                if(bool_display_received):
                    print(f"Received {len(data)} | {data}")
                    print(f"Sent {byte_counter} bytes, {byte_counter/(1024)} KB, {byte_counter/(1024*1024)} MB")
            except ValueError:
                pass
            
start_server = websockets.serve(handler, "localhost", server_websocket_port)
asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

Maintenant que nous avons notre entier localement avec UDP, il faut envoyé les commandes à World of Warcraft:
