# Veloren Trading Bot
|
|
|
|
A bot that buys, sells and trades with players.
|
|
|
|
The bot is containerized and can be run without compiling or building anything. Alternatively, you
|
|
can clone this repository and build the image yourself or build the binary directly with Cargo if
|
|
you are familiar with Rust.
|
|
|
|
|
|
|
|
## Warnings and Notices
|
|
|
|
- This project is **not officially supported** by the Veloren team. It will connect to the official
|
|
Veloren server by default, but the moderators have the final say in whether it is allowed or
|
|
not. **If you are asked not to use it, do not use it**.
|
|
- This is **not a cheat bot**. It does not give the player any advantage in the game. It is
|
|
intended to be a fun addition to the game that can help players trade items with each other.
|
|
- This project may have bugs. You are encouraged to report them to the author but the author takes
|
|
no responsibility for any lost items. **No such incidents have been reported so far.**
|
|
- This program **handles your password securely** and does nothing with it except connecting to the
|
|
veloren server during launch. However, third-party video game software is often infected with
|
|
malware. You should **review the source code** or ask someone you trust to do so for you.
|
|
- You are welcome to make changes to the code or fork the project. The author is open to
|
|
contributions and suggestions. But you **must indicate that the software has changed and
|
|
distribute it under the same license**, which also requires it being open-source. You may not
|
|
distribute the modified software as if it were the original.
|
|
|
|
## In-Game Commands
|
|
|
|
The bot is able to respond to the following commands, which must be sent via "/tell".
|
|
|
|
- `price [search term]`: Returns the buy/sell offers of any item whose name or ID contains the
|
|
search term.
|
|
- `admin_access`: Admin-only, prompts the bot to send a trade invite to the sender, after which it
|
|
will give away and accept any items until the trade ends.
|
|
- `announce`: Admin-only, sends the announcement message to "/region". This will reset the
|
|
announcement timer to 45 minutes.
|
|
- `location`: Returns the bot's current town or, if it is not in a town, its current position.
|
|
- `sort [count (optional)]`: Admin-only, sorts the inventory once or the given number of times.
|
|
- `pos [x] [y] [z]`: Admin-only, sets the bot's desired position where it will try to stand (must
|
|
be close to the bot's current position).
|
|
- `ori [0-360]`: Admin-only, sets the bot's desired orientation (or facing direction).
|
|
|
|
## Prerequisites
|
|
|
|
You must have either [Docker](docker.com) or [Podman](podman.io) installed.
|
|
|
|
## Usage
|
|
|
|
All of these steps can be done with Docker but Podman is shown for the examples. If you use
|
|
Docker, just replace "podman" with "docker" in your commands.
|
|
|
|
### Setup
|
|
|
|
Create a "secrets.toml" file:
|
|
|
|
```toml
|
|
# secrets.toml
|
|
username = "bot_username"
|
|
password = "bot_password"
|
|
character = "bot_character"
|
|
|
|
# You may add usernames or UUIDs to this list. The only advantage of using UUIDs is that it will
|
|
# persist accross changes to your username or player alias.
|
|
admins = ["my_username"]
|
|
```
|
|
|
|
Then create a secret to pass the file securely to the container.
|
|
|
|
```sh
|
|
podman secret create secrets.toml secrets.toml
|
|
```
|
|
|
|
You will also need a "config.toml" and it needs it be in a "config" directory that can be mounted
|
|
to the container:
|
|
|
|
```toml
|
|
# config/config.toml
|
|
|
|
# Optional. The bot will connect to the official server if this is not set.
|
|
game_server = "server.veloren.net"
|
|
|
|
# Optional. The bot will connect to the official auth server if this is not set. Be careful
|
|
# if you set this, your username and password will be sent to this server. Most servers use the
|
|
# official auth server so you can probably leave this out, even if you are using an alternate
|
|
# game server.
|
|
auth_server = "https://auth.veloren.net"
|
|
|
|
# Optional. Change these to the desired X, Y, Z coordinates. The bot will try to stand here, but
|
|
# the coordinates must be close to the bot's spawn point. If not set, the bot will stand at its
|
|
# spawn point. Its position can be changed in-game with the "pos" command.
|
|
position = [0, 0, 0]
|
|
|
|
# Optional. (0 = North, 90 = West, 180 = South, 270 = East) If not set, the bot will face North.
|
|
# Its orientation can be changed in-game with the "ori" command.
|
|
orientation = 0
|
|
|
|
# Optional. Announcements are sent every 45 minutes. If not set, the bot will not make announcements.
|
|
announcement = "I love cheese!"
|
|
|
|
# The buy_prices and sell_prices tables are required. The keys are item definition IDs and the
|
|
# values are the price in coins. You may type in-game "/give_item common.items." and press Tab to
|
|
# explore the item definition IDs. Then just leave off the "common.items." part in this file.
|
|
[buy_prices]
|
|
"food.cheese" = 50
|
|
|
|
[sell_prices]
|
|
"consumable.potion_minor" = 150
|
|
|
|
# Modular weapons are listed by their components: "material|primary|secondary". The material is
|
|
# snake_cased and you can omit the "common.items.modular.weapon.[primary|secondary]" from the
|
|
# modular components.
|
|
"iron|sword.greatsword|sword.long" = 1_000
|
|
```
|
|
|
|
### Running
|
|
|
|
Run the container:
|
|
|
|
```sh
|
|
podman run \
|
|
--detach \
|
|
--name trade_bot \
|
|
--secret secrets.toml \
|
|
--volume ./config/:/root/config/:Z \
|
|
--env CONFIG=/root/config/config.toml \
|
|
--env SECRETS=/run/secrets/secrets.toml \
|
|
--env RUST_LOG=trade_bot \
|
|
git.jeffa.io/jeff/trade_bot
|
|
```
|
|
|
|
View the log output with `podman logs -f trade_bot`.
|
|
|
|
### Building
|
|
|
|
Clone this repository. From the project root:
|
|
|
|
```sh
|
|
podman build . -t trade_bot
|
|
```
|
|
|
|
Then follow the [above](#running) steps with the tag "trade_bot" instead of
|
|
"git.jeffa.io/jeff/trade_bot".
|
|
|
|
## Changelog
|
|
|
|
- 9/2/2024:
|
|
- Added the "location" command.
|
|
- Removed the "{location}" feature from the announcement message. Announcements are now sent to
|
|
"/region" so this feature is now used by the "location" command.
|
|
- Changed announcements to be sent to "/region" instead of "/world". The moderators on the official
|
|
server have asked for this, so please don't run an old version to circumvent the change.
|
|
- Removed the "Ouch!" and "That hurt!" messages when the bot is attacked. The moderators have also
|
|
asked for this.
