Game preview

Time = 2min	Time = 4min

Goal

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

Rounds

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

Game map

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)

Mining

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:

Fights

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

Vehicles

	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

Additional rules:

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

Scoring

+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

The control center - the AI

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.

`game_map`

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.

Optimizing development

There are 3 ways you can speed up your development.

1. The high contrast mode

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

2. Crystal boost

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).

3. Use the 'Pause' Luke (experimental)

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.
