Does anyone have an realistic AI settings? Like on Sapien? It would also be great if someone gives me an actor_variant who has a good setting on it too. Thanks! Bye.

exactly :)

:P Okay.

yeah use the settings in the tag using guerilla.

All about a.i

.actor_variant tag

flags

can shoot while flying - Can shoot while in a vehicle
interpolate color in HSV - No clue
has unlimited grenades - has unlimited 'nades
moveswitch stay w/ friends - Not entirely sure, but likely changing the movement type between running and crouching for actors in the same squad or encounter to stay close to each other
active camouflage - AI uses active camo. I have never seen this work personally.
super active camouflage - Better camo? This never seemed to work.
cannot use ranged weapons - can only melee
prefer passenger seat - prefer passenger seat

actor definition - defines tag explaining general unit behavior
unit - allows for the physical structure of the unit to be selected
major variant - occasionally, the engine wil decide to spawn a different version of the unit. This is where the major variant.actor_variant is chosen.

movement switching

movement type - run, crouch, or switch between the two
initial crouch chance - chance to crouch (when spawned?) 0 = never. 1 = always
crouch time - How long crouched
run time - how long running
(Personally, I have never been able to see any change when altering these values. This could be that the bipeds or actors I used were unsuited for movement switching.)

ranged combat

weapon - allows for the actor's weapon to be chosen. Choose from the weapons folder instead of the items collection, contrary to how a map is populated with arms
maximum firing distance - max firing range
rate of fire - number of times trigger is pulled per second
projectile error - How many degrees from crosshair center projectile flies
first burst delay time - Time before AI will shoot after acquiring target
new-target firing pattern time - Time before AI will shoot at a new target after losing a previous one
surprise delay time - Time before AI will react to stimulus of the surprise. This is probably in addition to the times above
surprise fire-wildly time - Time that AI will shoot without aiming after being surprised
death fire-wildly chance - Chance that AI will shoot randomly around while in the throes of death. 0 = never. 1 = always.
death fire-wildly time - Time AI will shoot wildly while dying for
desired combat range - AI will try to fight within this combat range, moving to stay within it. I have noticed that AI tend to to shoot at all when outside this range.
custom stand gun offset - No clue
custom crouch gun offset - No clue, but for crouching rather than standing :P
target tracking - How well the AI tracks its target. 0 = not at all. 1 = perfectly
target leading - How well the AI predicts the movement of target and the positioning of the crosshair to match. 0 = not at all. 1 = perfectly
weapon damage modifier - How much the damage of the weapon is multiplied by upon impact
damage per second - How much damage a target will receive, regardless of shots hit

burst geometry

burst origin radius - How far from the start of the burst does the crosshair drift
burst origin angle - If not zero, burst may drift up or down. Magnitude depnding on value.
burst return length - How far back towards the target the burst travels
burst return angle - Same as origin angle, but from the point at which the return begins (Apparently)
burst duration - How long a burst is fired for. Affects speed of burst movement
burst separation - How long between bursts.
burst angular velocity - How fast actor can turn while firing
special damaga modifier - Any additional damage shots do. Added (or multiplied) to standard error.
special projectile error. Additional error added to projectiles.

firing patterns

Details of "new-target", "moving", and "berserk" are at the top of the section on the tag.
burst duration - How long a burst is fired for
burst separation - Time between bursts
rate of fire - Times per second trigger is pulled
projectile error - angle from intended projectile destination

So new-target burst duration would be the burst duration when a target first appears.

Special-case firing properties

super-ballistic range - The range at which the AI begins to aim at the sky, hoping to land the shot in a large arc.
bombardment range - AI adds error to burst targets to show bombardment inaccuracy above this range
modified vision range - How far actor can see when in the special-case
special-fire mode - What the AI will do when in a special-fire situation: overcharge weapon or pull secondary trigger
special-fire situation - What triggers the special-fire situation
special-fire chance - Chance of the situation occuring if appropriate conditions arise. 0 = never, 1 = always.
special-fire delay - Minimum time between allowed instances of special-fire

berserking and melee

melee range - Range within which unit will try to melee enemy
melee abort range - Range outside which unit will cease to attempt to melee target
berserk firing ranges - Berserking actor will try to maintain this distance or closer
berserk melee range - Range when actor tries to melee enemy when berserking
berserk melee abort range - Range outside which berserking AI stops trying to melee enemy.

grenades

grenade type - Type of grenade thrown, sticky or frag
trajectory type - How 'nade is thrown: toss (what is this?), lob (what's the difference?) bounce (AI will try to bounce the grenade to reach the target)
grenade stimulus - What triggers a grenade throw
minimum enemy count - How many enemies have to be present within "enemy radius" for the AI to consider throwing a 'nade
enemy radius - Radius of circle indicating which enemies count toward the "minimum enemy count"
grenade velocity - How fast the 'nade travels
grenade ranges - Ranges between which grenade throws will be attempted
collaterla damage radius - If there are friendlies within this area, 'nade will not be thrown.
grenade chance - Chance of grenade when all criteria are met.
grenade check time - How often AI checks for grenade throw conditions
encounter grenade timeout - How long after another member of the encounter has thrown a 'nade before another 'nade can be thrown

items

equipment - What is equipment?
grenade count - Number of 'nades AI carries. Number that it drops if "unlimited grenades" is checked
dont drop grenades chance - How likely grenades WILL NOT be dropped, even if actor still has 'nades
drop weapon loaded - Fraction of clip already loaded in dropped weapon
drop weapon ammo - How much total ammo a dropped weapon has. Chosen randomly between two values

unit

body vitality - Amount of health unit has
shield vitality - Amount of shields unit has. 0 = no shields
shield sapping radius - No clue
Forced shader permutation - No clue

CHANGE COLORS - Changing the color of the actor. I have found that this method does not seem to work for me. I use the color permutations in the biped tag instead. If anyone can suggest something to make this method work, I welcome it, as it would make changing actor colors much easier.

The thing about the vehicle tag is that most of what is there refers not only
to how AI drive the vehicle, but also to the vehicle in general. For these
purposes, I shall only deal with the options that apply to artificial
intelligence. Perhaps in the future, I will update everything on the vehicle
tag, but I don't see that happening unless someone really wants it.

flags
not a pathfinding obstacle - AI will not see this vehicle as something to
consider when determining the best path to a location. (I've found that the AI
aren't very good at determining if a vehicle is in the way or not, even if
this option isn't checked, as they are often seen getting stuck on an
warthog.)

VEHICLE

flags

ai weapon cannot rotate - Weapon on the vehicle cannot turn
ai does not require driver - Vehicle can drive without an AI driver
ai unused -
ai driver enable - AI driver can use the vehicle
ai driver flying - AI driver is flying (uses 3D coordinates)
ai driver can-sidestep - AI driver can strafe (facing one direction and moving
side to side rather than turning and moving)
ai driver hovering - AI driver does not register as contacting the ground
type - type of vehicle (this does have an effect as standard AIs already seem
to have preprogrammed ways to drive different types of vehicles)
ai sideslip distance - how far the AI diverges from a path
ai destination radius - how far from the destination point the AI can go to
ai avoidance distance - how far from obstacles (and maybe dangerous things)
the AI will keep
ai pathfinding radius - how far the AI looks to pathfind
ai charge repeat timeout - how long between charges the AI has to wait
ai strafing abort range - how far away the AI has to be before it abandons
strafing
ai oversteering bounds - how much the AI oversteers (I believe it's like
attempts to slide)
ai steering maximum - fraction of the maximum steering the AI can turn at
maximum
ai throttle maximum - fraction of the maximum throttle the AI can turn at
maximum
ai move-position time - how long the AI waits between move positions


If you can script, then use this script:

(script continuous aidrive
(object_create_anew elite)
(object_create_anew banshee)
(unit elite)
(unit banshee)
(unit_enter_vehicle elite banshee "banshee-driver")
(sleep_until (= (vehicle_test_seat_list banshee "banshee-driver" elite) true) 5)
(ai_attach elite banshee-driving/pwnage)
(ai_command_list banshee-driving/pwnage haxdriver)
(sleep_until (= (and (= (unit_get_health elite) 0) (= (unit_get_health banshee) 0)) true)))



NOTE: AI is unable to drive unless the driver seat is also attached to the gunner seat.

This script means:

It makes a elite biped and a banshee. The script makes them both units, and the elite biped enters the banshee. This script waits untill that seat for the banshee is filled by the elite biped, then continues. From there, it attaches it to a encounter, and gives it a command list. Then it sleeps untill both of them die, which makes it start all over again. They perfectly drive the entire command list.

Why/How this happens:

When the biped goes into the vehicle, it doesn't have it's AI yet, so it thinks its still on the ground, not in a vehicle. When the script attaches the biped to the encounter and gives it the command list, the ai believes its on the ground still, not in the vehicle.

The result? A elite in a banshee that perfectly follows the command list and attacks people.

The command list is just a figure eight around the map.

Gee, thanks ally. This will totally help.
