This snake was my entry into the 2017 battlesnake competition. It defeated the most bounty snakes and was a contender in the semi finals of the competition.
There are no dependencies just build with
go build .
Then run with
./yournewdad
The server runs by default on port 9000 although this is configurable with environment variables
PORT=8080 ./yournewdad
will run the server on port 8080 instead of 9000
Alternatively, if you just want to play against this snake it will perpetually live at http://yournewdad.herokuapp.com/
There are a lot of tests included with this snake most of them test behaviour. To run the tests run
go test
while in the directory
To add new tests when running the server add the environment variable YND_LOG
YND_LOG=true ./yournewdad
This will print out the incomming json blob on every request. You then add this to the gamestrings.go file and you can reference the blob in your test (see filters_test.go) for examples
...
data, err := NewMoveRequest(gameString17)
if err != nil {
t.Errorf("%v", err)
}
...NewMoveRequest is a function that parses the json blob into the internal data structure used in this program.
The snake typically dies by running head on into other snakes or by starving if you can find a way to detect head on colisions that would be a major improvement into the usability of the snake.
The beginnings of my headon collision implemetaion can be found in headon.go and the corresponding failing tests can be found in headon_test_skip.go
It would also be really nice to have more metrics about the win loss rate of the snake overallI want to implement some sort of mechanism that tests if you have won or lost the game then stores this information so that you can view the win loss and kill ratio of the snake.
