Showcase

Installation

You need to have Python 3.10 or above installed. If you want to run the bot using Docker see Using Docker.

git clone git@github.com:offish/tf2-express.git
cd tf2-express
pip install -r requirements.txt

Note

You need to host a MongoDB server for the bot to work. Download the free community version here. You may also want to install MongoDB Compass to access/modify/delete collections manually.

Setup

Note

Make a copy of config.example.json and name it config.json. Make sure it is in the same folder as the example file. Update credentials and set your preferred options.

Example config:

{
    "bots": [
        {
            "username": "username",
            "password": "password",
            "api_key": "111AA1111AAAA11A1A11AA1AA1AAA111",
            "shared_secret": "Aa11aA1+1aa1aAa1a=",
            "identity_secret": "aA11aaaa/aa11a/aAAa1a1=",
            "options": {
                "use_backpack_tf": true,
                "backpack_tf_token": "token",
                "enable_deals": false,
                "inventory_provider": "steamsupply",
                "inventory_api_key": "mySteamSupplyApiKey",
                "accept_donations": true,
                "decline_trade_hold": true,
                "allow_craft_hats": true,
                "save_trade_offers": true,
                "owners": [
                    "76511111111111111",
                    "76522222222222222"
                ]
            }
        }
    ]
}

Note

As of v3.0.0 tf2-express only supports running one bot instance at a time. It will use the first entry in bots in the config.

Running

# tf2-express/
python main.py # start the bot
python panel.py # start the gui

Now you can visit the GUI at http://127.0.0.1:5000/

Logs will be available under logs/express.log. Level is set to DEBUG, so here you will be able to see every request etc. and more information than is shown in the terminal.

Warning

Do NOT share your logs or config files with anyone before removing sensitive information. This might leak your API_KEY and more.

Updating

# tf2-express/
git pull
pip install --upgrade -r requirements.txt
# update packages like bptf, tf2-utils, tf2-data and tf2-sku
# which the bot is dependant on

Using Docker

First configure the bot like shown in Setup. Then change the timezone in the Dockerfile, it is set to use Oslo time by default.

make build # will build the tf2-express docker image and install dependencies
make run # will start mongodb and tf2-express

The GUI does not start automatically. To start the GUI run this:

make gui

The GUI will then be available at http://127.0.0.1:5000.

Explanation

Random Craft Hats

If a craftable hat does not have a specific price in the database, it will be viewed as a Random Craft Hat (SKU: -100;6), if enable_craft_hats is enabled.

Caution

This applies to any craftable unique hat, which includes hats such as The Team Captain, Earbuds, Max Heads etc. If these to not have their own price in the database, they will be priced as a Random Craft Hat, if this option is enabled.

Simply open the GUI and add "Random Craft Hat" to the pricelist. Set the buy and sell price to whatever you want. Random Craft Hats cannot get automatic price updates.

3rd Party Inventory Providers

Avoid Steam's inventory rate-limits by using a third party provider like SteamApis, Steam.Supply or your own.

3rd Party Deals

"Deals" in this context are data which is emitted by third party using a TCP socket. This data will be acted on, such as sending an offer using the included trade URL and price. They are named "deals" as I've been using it for arbitrage purposes.

Important

As of tf2-express v3.0.0 deals are currently broken.

Testing

# tf2-express/
pytest

Every test should succeed except for the version check. The version needs to be incremented to pass this test.
