AI Profiles

• Defines AI profile global variables

$Default Profile:

• Unless the name of the default profile is the same as the name of one the additional AI profiles game defaults to retail AI behaviour. Non-default AI profiles must be selected with FRED for each mission separately.

The following entries are boolean flags. They can be set to YES or NO, TRUE or FALSE, OUI or NON, HIja′ or ghobe′, etc. The default is NO.

$big ships can attack beam turrets on untargeted ships:

FS2 Open, 3.6.x:

• If set, big ships can attack a beam turret that's firing on them from a ship that they don't currently have targeted.

$smart primary weapon selection:

FS2 Open, 3.6.x:

• If set, enables the new primary weapon selection method

$smart secondary weapon selection:

FS2 Open, 3.6.x:

• If set, enables the new secondary weapon selection method (including proper use of bomber+ missiles)

$smart shield management:

FS2 Open, 3.6.x:

• If set, enables smart shield management (previously was -smart_shields on the command line)

$allow rapid secondary dumbfire:

FS2 Open, 3.6.x:

• If set, allows an AI ship to switch to rapid fire for dumbfire missiles

$huge turret weapons ignore bombs:

FS2 Open, 3.6.x:

• If set, causes huge turret weapons (including anti-capship beams) to not target bombs

$don't insert random turret fire delay:

FS2 Open, 3.6.x:

• If set, removes the random turret fire delay (from .1 to .9 seconds) inserted in addition to AI Fire Delay Scale

$hack improve non-homing swarm turret fire accuracy:

FS2 Open, 3.6.x:

• If set, triggers a hack to improves the accuracy of non-homing swarm missiles by firing them along the turret's last fire direction rather than the direction it currently faces
• Also disables swarm weapons ability to fire only on the 'turrets barrel line'.

$shockwaves damage small ship subsystems:

FS2 Open, 3.6.x:

• If set, shockwaves will cause damage to small ship subsystems (like in FS1)

$navigation subsystem governs warpout capability:

FS2 Open, 3.6.x:

• If set, ships will not be able to warp out if their navigation subsystem is destroyed or low in strength

$ignore lower bound for minimum speed of docked ship:

FS2 Open, 3.6.x:

• If set, there will be no lower bound for the speed at which docked ships move (like in FS1).
• When a ship is towing another ship or ships, the towing ship will be slowed down to a degree depending on the total mass of all docked ships. In FS1, the ships could slow down to an arbitrarily slow speed, even a fraction of a m/s above zero. In FS2, there is a lower bound on this behavior so that all ships are guaranteed to move at a minimum docked speed. When set, this flag removes the lower bound and restores FS1 behavior.

$disable linked fire penalty:

FS2 Open, 3.6.x:

• If set, there will be no penalty for linking prinaries. Normally, the rate of fire is divided by the number of linked guns.

$disable weapon damage scaling:

FS2 Open, 3.6.x:

• If set, weapons will do the same damage to a ship regardless of "big damage", "supercap", etc. ship types.

$use additive weapon velocity:

FS2 Open, 3.6.x:

• If set, weapons will inherit their firing ship's velocity. A ship travelling quickly will fire weapons faster than a ship travelling slowly. This also improves the accuracy of weapons fired while gliding.

$use newtonian dampening:

FS2 Open, 3.6.x:
