We have created a video game that is designed to be played by a small python program, rather than a human. Conference attendees can participate in a tournament where they (either alone or in a team) each submit a bot that will play the game, and at the end of the conference, we will have a tournament session where everyone can come and watch our strange creations play against each other (either brilliantly or it may all go wrong!).

The topic of the game is a sci-fi war on a foreign planet, set far in the future. We do not condone war and violence, we just want to make a fun event for EuroPython participants.

• Register your team: fill in the form at https://forms.gle/v2s9oHZ1xLTUo5ov7 (30 spots available)
• You will be given a private GH repository in the europython2023gametournament organisation
• Read the game rules below and start working on your bot
• Ask questions on the Discord forum ai-game-tournament
• Creating alliances is authorized (betrayals are also allowed!)
• Once your bot is ready, make sure you copy it into the main branch of the repo you were given
• Deadline is 15:00 on Friday July 21st
• Tournament will be 15:30 - 16:45 on Friday July 21st in the Open Space area

Preview

Time = 2min	Time = 4min

• Mine resources to build an army
• Destroy enemy bases and eliminate other players

• All participants play on the map at the same time
• Each round lasts 8 minutes
• The tournament will consist of 8 rounds of 8 minutes

• The map is auto-generated every round
• It has periodic boundary conditions (for example when a vehicle arrives at the right edge of the map, it will re-appear at the left edge)
• The map size will scale with the number of players (more players = larger map)
• Coordinate system: lower left corner: (x=0, y=0), upper right corner: (x=nx, y=ny)

• Everyone starts with 1 base, housing 1 mine
• Every timestep, each mine will extract crystal = 2 * number_of_mines
• Crystal is used to build mines and vehicles
• Mines too close to other bases compete for resources: crystal = 2 * number_of_mines / number_of_bases_inside_square_of_80px
• Bases that contain mines that are competing with others will have a “C” label on them:

• Whenever two or more vehicles or bases from opposing teams come within 5px from each other, they will fight
• During each time step, every object hits all the others with its attack force, and it takes damage from all other objects

	Tank	Ship	Jet
Speed	10	5	20
Attack	20	10	30
Health	50	200	50
Cost	500	2000	4000
Can travel	On land	On sea	Anywhere
		Can turn into base

• Mine cost doubles for every new mine on a given base (first mine=1000, second=2000, third=4000, etc…)
• Base has health = 100, mine has health = 50 (both have 0 attack)
• Vehicles move at speed * dt (dt = 1/15s)
• A ship can be turned into a new base, by calling convert_to_base()
• A conversion to base will only work if there is land in the immediate vicinity
• A player is eliminated when all his/her bases have been destroyed
• If a player is eliminated, all his/her vehicles disappear instantly

• 1 point if you destroy a base
• If a player gets eliminated, they receive a number of points equal to the number of players that were eliminated before them
• At the end of the round, every player still alive gets a number of points equal to the number of eliminated players

• To play the game, you will have to create a Python program.
• It should contain a class named PlayerAI and that class should have a method named run.
• Every time step, the run method will be called, and it will be inside that function that you should control your vehicles, decide what to build, etc...
• You are provided with a template_ai.py to give you an example.

Look at the comments in the template_ai.py for details on what information is available to you at every time step and what methods can be called.

• The game_map is one of the arguments the run function will receive.
• It is a Numpy array that automatically gets filled when your vehicles or bases visit that region of the map.
• 1 means land, 0 means sea, -1 means no info.
• Any visit makes anything in that part of the map permanently visible.
• This is basically what defines which enemy bases and vehicles you get in your info every time step.

There are 3 ways you can speed up your development.

Activate high_contrast = True to see the land borders better and competing areas for mines:

Waiting for things to develop can be time consuming. You can artificially increase mine yield using crystal_boost=5 (or any number you want, although behavior is untested beyond 10).

While the game is running, you can hit P on the keyboard. This will pause the game. You can edit your AI code. When the game resumes (hit P again), it will reload your AI module.
