A simple Battlesnake written in Mule and DataWeave
This is a basic implementation of the Battlesnake API. It's a great starting point for anyone wanting to program their first Battlesnake using Mule and DataWeave.
The Quick Start Coding Guide provides the full set of instructions to customize, register, and create your first games with your Battlesnake!
- A free Battlesnake Account
- Anypoint Studio for local development
- Mule Runtime
- Anypoint Platform account for deploying to Cloudhub
- Fork and clone this repo
- Import this project in Anypoint Studio
- Run mule-battlesnake mule application. This will expose API at http://localhost:8081/api that you can use for creating battlesnakes.
- Expose local http to internet with ngrok or similar tools.
- Follow Battlesnake quickstart quide to create your battlesnake and play
Project's POM is configured for deploying to Cloudhub using Mule Maven Plugin. See the mule-maven-plugin configuration in pom.xml. Set appropriate values for properties and run mvn deploy -DmuleDeploy.
Once deployed to Cloudhub, use application's URL https://{ch-app-name}.{region}.cloudhub.io/api to create your battlesnake.
Accessing http://localhost:8081/api will return response like below. You can change these parameter values from src/main/resources/application.yaml.
{
"apiversion": "1",
"author": "mmsonline",
"color": "#888888",
"head": "default",
"tail": "default",
"version": "0.0.1-beta"
}This resource is called by the game engine periodically to make sure your Battlesnake is healthy, responding correctly, and to determine how your Battlesnake will appear on the game board. See Battlesnake Personalization for how to customize your Battlesnake's appearance using these values.
Whenever you update these values, go to the page for your Battlesnake and select 'Refresh Metadata' from the option menu. This will update your Battlesnake to use your latest configuration and those changes should be reflected in the UI as well as any new games created.
On every turn of each game your Battlesnake receives information about the game board and must decide its next move. Possible moves are "up", "down", "left", or "right" and initially your Battlesnake will choose a move randomly. Your goal as a developer is to read information sent to you about the game (available in the payload) and decide where your Battlesnake should move next. All your Battlesnake logic lives in /src/main/resources/dw/move-snake.dwl, and this is the code you will want to edit.
See the Battlesnake Game Rules for more information on playing the game, moving around the board, and improving your algorithm.
If you're looking for the Single Player Mode of Battlesnake, or something to practice with between events, check out Challenges.
Once you've made your Battlesnake behave and survive on its own, you can enter it into the Global Battlesnake Arena to see how it performs against other Battlesnakes worldwide.
Arenas will regularly create new games and rank Battlesnakes based on their results. They're a good way to get regular feedback on how well your Battlesnake is performing, and a fun way to track your progress as you develop your algorithm.
