Installation

To install the engine as a local package, open your terminal and run

pip install --user --upgrade battlehack20

(Depending on how your pip is set up, you may need to replace pip with pip3.)

Test it out by trying:

python3 run.py examplefuncsplayer examplefuncsplayer

You should see a game between examplefuncsplayer and examplefuncsplayer being played.

NOTE: if you're on Windows and you get incomprehensible output, try instead:

python3 run.py examplefuncsplayer examplefuncsplayer --raw-text

If your code is in a directory ~/yourcode/coolplayer then you can run it against examplefuncsplayer using

python3 run.py examplefuncsplayer ~/yourcode/coolplayer

Running Interactively

Run

python3 -i run.py examplefuncsplayer examplefuncsplayer

This will open an interactive Python shell. There, you can run

step()

which advances the game 1 turn. This is very useful for debugging.

More options

Run

python3 run.py -h

to list all possible options for running.

For example, turning off debug mode, which is on by default, can be helpful:

python3 run.py examplefuncsplayer --debug false

Advanced usage

Interacting directly with the battlehack20 API will give you more freedom and might make it easier to debug your code. The following is a minimal example of how to do that.

$ python3
>>> import battlehack20
>>> code = battlehack20.CodeContainer.from_directory('./examplefuncsplayer')
>>> game = battlehack20.Game([code, code], debug=True)
>>> game.turn()

You should see the output:

[Game info] Turn 1
[Game info] Queue: {}
[Game info] Lords: [<ROBOT WHITE HQ WHITE>, <ROBOT BLACK HQ BLACK>]
[Robot WHITE HQ log] Starting Turn!
[Robot WHITE HQ log] Team: Team.WHITE
[Robot WHITE HQ log] Type: RobotType.OVERLORD
[Robot WHITE HQ log] Spawned unit at: (0, 11)
[Robot WHITE HQ log] Done! Bytecode left: 19928
[Robot BLACK HQ log] Starting Turn!
[Robot BLACK HQ log] Team: Team.BLACK
[Robot BLACK HQ log] Type: RobotType.OVERLORD
[Robot BLACK HQ log] Spawned unit at: (15, 5)
[Robot BLACK HQ log] Done! Bytecode left: 19927

If you're curious, this is how the run.py script works. Study the source code of run.py to figure out how to set up a viewer.
