92            sessiontype, ba.FreeForAllSession

Class method override; returns True for ba.DualTeamSessions and ba.FreeForAllSessions; False otherwise.

def get_supported_maps(cls, sessiontype: type[ba._session.Session]) -> list[str]: 
95    @classmethod
96    def get_supported_maps(cls, sessiontype: type[ba.Session]) -> list[str]:
97        return ba.getmaps('keep_away')

Called by the default ba.GameActivity.create_settings_ui() implementation; should return a list of map names valid for this game-type for the given ba.Session type.

slow_motion = False

If True, runs in slow motion and turns down sound pitch.

def get_instance_description(self) -> Union[str, Sequence]: 
131    def get_instance_description(self) -> str | Sequence:
132        return 'Carry the flag for ${ARG1} seconds.', self._hold_time

Return a description for this game instance, in English.

This is shown in the center of the screen below the game name at the start of a game. It should start with a capital letter and end with a period, and can be a bit more verbose than the version returned by get_instance_description_short().

Note that translation is applied by looking up the specific returned value as a key, so the number of returned variations should be limited; ideally just one or two. To include arbitrary values in the description, you can return a sequence of values in the following form instead of just a string:

This will give us something like 'Score 3 goals.' in English

and can properly translate to 'Anota 3 goles.' in Spanish.

If we just returned the string 'Score 3 Goals' here, there would

have to be a translation entry for each specific number. ew.

return ['Score ${ARG1} goals.', self.settings_raw['Score to Win']]

This way the first string can be consistently translated, with any arg values then substituted into the result. ${ARG1} will be replaced with the first value, ${ARG2} with the second, etc.

def get_instance_description_short(self) -> Union[str, Sequence]: 
134    def get_instance_description_short(self) -> str | Sequence:
135        return 'carry the flag for ${ARG1} seconds', self._hold_time

Return a short description for this game instance in English.

This description is used above the game scoreboard in the corner of the screen, so it should be as concise as possible. It should be lowercase and should not contain periods or other punctuation.

Note that translation is applied by looking up the specific returned value as a key, so the number of returned variations should be limited; ideally just one or two. To include arbitrary values in the description, you can return a sequence of values in the following form instead of just a string:

137    def create_team(self, sessionteam: ba.SessionTeam) -> Team:
138        return Team(timeremaining=self._hold_time)

Create the Team instance for this Activity.

Subclasses can override this if the activity's team class requires a custom constructor; otherwise it will be called with no args. Note that the team object should not be used at this point as it is not yet fully wired up; wait for on_team_join() for that.

def on_team_join(self, team: bastd.game.keepaway.Team) -> None: 
140    def on_team_join(self, team: Team) -> None:
141        self._update_scoreboard()

Called when a new ba.Team joins the Activity.

(including the initial set of Teams)

def on_begin(self) -> None: 
143    def on_begin(self) -> None:
144        super().on_begin()

150        self._update_flag_state()
151        Flag.project_stand(self._flag_spawn_pos)

Called once the previous ba.Activity has finished transitioning out.

At this point the activity's initial players and teams are filled in and it should begin its actual game logic.

def end_game(self) -> None: 
185    def end_game(self) -> None:
186        results = ba.GameResults()
187        for team in self.teams:
188            results.set_team_score(team, self._hold_time - team.timeremaining)
189        self.end(results=results, announce_delay=0)

Tell the game to wrap up and call ba.Activity.end() immediately.

This method should be overridden by subclasses. A game should always be prepared to end and deliver results, even if there is no 'winner' yet; this way things like the standard time-limit (ba.GameActivity.setup_standard_time_limit()) will work with the game.
