Functions
void	AI_Init (void)

	Check whether friendly units are in the line of fire when shooting. More...

bool	AI_FighterCheckShoot (const Actor actor, const Edict check, const fireDef_t *fd, float dist)

Todo:

fill z_align values

optimize this

Todo:: do this decently, only penalizing the visible part of walk and penalizing much more for reaction shooters around; now it may remove some tactical options from aliens, e.g. they may now choose only the closer doors; however it's still better than going three times around soldier and only then firing at him

Todo:: also add bonus for fleeing from reaction fire and a huge malus if more than 1 move under reaction

Tries to search a spot where actor will be more closer to the target and behind the target from enemy (ie hide behind target)

Parameters

[in]	actor	The actor edict.
[in]	from	The grid position the actor is (theoretically) standing at and searching the nearest location from
[in]	target	Tries to find the nearest position to this location
[in]	tu	The available TUs of the actor

◆ AI_GetHidingTeam()

int AI_GetHidingTeam ( const Edict * ent )

Returns the value for the vis check whenever an ai actor tries to hide. For aliens this is the inverse team - see the vis check code for the inverse team rules to see how this works. For civilians we have to specify the alien team and can't use the inverse team rules. This is needed because the inverse team rules aren't working for the civilian team - see TEAM_CIVILIAN.

Returns: A negative team number means "every other team" as the one from the given ent. See the vis check functions for the inverse team rules for more information.
