Combat’s classic tank mode is an adversarial game where prediction, and positioning are key.

The players move around the map. When your opponent is hit by your bullet, you score a point. Note that your opponent gets blasted through obstacles when it is hit, potentially putting it in a good position to hit you back.

Whenever you score a point, you are rewarded +1 and your opponent is penalized -1.

Parameters specific to combat-tank are

combat_tank_v2.env(has_maze=True, is_invisible=False, billiard_hit=True)

has_maze: Set to true to have the map be a maze instead of an open field

is_invisible: If true, tanks are invisible unless they are firing or are running into a wall.

billiard_hit: If true, bullets bounce off walls, in fact, like billiards, they only count if they hit the opponent’s tank after bouncing off a wall.
