typedef struct esct esct

An abbreviation for "Evaluate Ship as Closest Target", defines a data structure used to hold the required arguments for evaluating a prospective closest target to an attacked object.

typedef struct htarget_list htarget_list
typedef struct target_display_info target_display_info

Function Documentation

bool evaluate_ship_as_closest_target ( esct *  esct_p)

evaluate a ship (and maybe turrets) as a potential target

Check if shipp (or its turrets) is attacking attacked_objnum Provides a special case for player trying to select target (don't check if turrets are aimed at player)

Parameters
[in,out]*esctThe Evaluate Ship as Closest Target (esct) that will be used to determine if a target is a valid, harmful target and, if so, sets the min_distance attribute to the distance of either the attacker or the closest attacker's turret. Otherwise, min_distance is set to FLT_MAX
Returns
true if either the ship or one of it's turrets are attacking the player. Otherwise, returns false.

int hud_target_closest ( int  team_mask,
int  attacked_objnum,
int  play_fail_snd,
int  filter,
int  get_closest_turret_attacking_player 
)

Sets the Players[Player_num].current_target to the closest ship to the player that matches the team passed as a paramater.

The current algorithm is to simply iterate through the objects and calculate the magnitude of the vector that connects the player to the target. The smallest magnitude is tracked, and then used to locate the closest hostile ship. Note only the square of the magnitude is required, since we are only comparing magnitudes.

Parameters
[in]team_maskteam of closest ship that should be targeted. Default value is -1, if team doesn't matter.
[in]attacked_objnumobject number of ship that is being attacked
[in]play_fail_sndboolean, whether to play SND_TARGET_FAIL (needed, since function called repeatedly when auto-targeting is enabled, and we don't want a string of fail sounds playing). This is a default parameter with a value of TRUE.
[in]filterOPTIONAL parameter (default value 0): when set to TRUE, only fighters and bombers are considered for new targets.
[in]get_closest_turret_attacking_playerFinds the closest turret attacking the player if true. Otherwise, only finds the closest attacking ship, targeting the turret closest to the player.
Returns
: true (non-zero) if a target was acquired. Returns false (zero) if no target was acquired.
