Change log notes, v. 126347

Fixed: AI was more resistant to bullets while moving

  • The wrong inverse matrix was used for AI

  • This caused some discrepancies between fire geometry and hit points while soldiers were in motion

  • This resulted in them appearing too 'resistant' to being shot (e.g. headshots would not be detected correctly)

Change log notes, v. 126766

Fixed: Slow rotation of AI turrets in relaxed mode

  • Addresses an issue caused by a previous fix to turret rotation

  • This caused a slow, constant rotation of vehicle turrets when the AI was in relaxed/careless mode

  • Should
    be fixed :cool:

Change log notes, v. 126941

Fixed: An issue introduced in 126800 where AI would get stuck on the road should be solved.

  • Addresses an issue caused by a minor optimisation to AI pathfinding introduced in 126789

  • This was reverted in 126910

  • The optimisation is reintroduced in this version

This (re-introduced) optimisation offers only a very minor performance increase, but is part of a larger body of work that seeks to improve AI pathfinding.

If/when we have any further results, we'll let you know. In the mean time, please accept our apologies for any inconvenience - onwards to splendidness!

Change log notes, v. 127034

EXE rev. 127034 (game)

ENGINE

  • Fixed: Walking through building walls, building navigation and path-planning
  • Fixed: AI is not interrupted by hits during get in animations

Lately we've been
in the cargo buildings and towers. Some of it was quite... interesting.

If you've ever tried making your teammate enter a cargo building, you know it wasn't the easiest of tasks. AI soldiers seem more than glad to do all kind of stuff except follow you orders.

"Making it to the roof? Can't roger that, thank you, I'd rather crawl around the entrance"

In other cases, these guys would follow yours orders a bit too much. To the death one could say. Literally. We all know the fastest way to make it from the top of a tower to the ground is usually by jumping down. Well, while it may be considered a plausible solution in some cases, it kind of does not feel right.

If you nodded at least once while reading this, we hope you'll understand our decision to remove these, uh, 'features' from our game. You might still come across some similar issues from time to time, however, we're doing our best to make things history. We'd appreciate it if you could let us know about any improvements / problems specifically related to AI planning in these circumstances.

  • Fixed: Sling Loading commanding menu implementation
  • Updated: AI behavior when Sling Loading


Added: Enabled Firing from Vehicles

  • Find more about this little new feature Klamacz decided to implement after accidentally finding about some request on the feedback tracker... ;) Ok. Srsly now. Check OPREP: Firing from vehicles - written on behalf of the FFV Task Forks and the whole A3 team - to find out more about what's so exciting about the latest Dev branch update.
    And direct please all your feedback to


Updated: AI behavior when Sling Loading

  • Another AI remedy from Dr. Hladik - AI should generally fly more carefully with a cargo sling-loaded. AI should no longer smash its cargo into obstacles or even crash the helicopter itself because the turn was sharp and the load was to heavy.)

30-09-2014

EXE rev. 127396 (game)

  • Revert of fixes for AI navigation in buildings, until other problems that popped up with it are fixed internally

A fine example of Murphy's law - if you get excited about something too much... Once fixed a bigger package of pathfinding improvements may land on the Dev Branch at once.

EXE rev. 127551 (game)

ENGINE

06-10-2014

EXE rev. 127573 (game)

ENGINE

  • Improved: AI for Sling Loading cargo using both waypoints and commanding menu
  • AI is now more careful when flying above trees

The last two Dev Branch updates have brought some AI improvements - better management of AI sling-loading, more careful AI pilots* and a fix of http://feedback.arma3.com/view.php?id=18937. Not exactly AI but tightly AI-related are the Headless Client improvement.

*The AI pilots should better avoid collisions with objects and also pick their LZ more carefully. AI crashing with a helicopter should become a rare sight (unless one as a leader or scenario designer really forces the helicopter into e.g. dropping cargo under the powerlines). It may come in some situations at a cost of less tight maneuvers and longer time to transition into a hover.

EXE rev. 127617 (launcher)

Size: ~361 MB

DATA

  • Updated: AI rotation speed with various weapons

ENGINE

  • Updated: AI aiming speed tweaked with new dexterity of weapon data

The algorithm for rotation speed of the AI within a free-aim/upper body deadzone has been improved. (This applies almost exclusively to situations when the AI is using a weapon in a vehicle's cargo or when firing from a cover.)

Together with the change there's been a mass re-adjustment of dexterity property in weapons' configs.

Referential values are 0.8 - Titan, 1.2 - Zafir, 1.5 - MX and 1.9 - P07

24-10-2014

EXE rev. 127928 (game)

Good for paratroopers - they shouldn't collide with each other as they did previously when everyone jumped out at the same moment.

10-11-2014

EXE rev. 128152 (game)

  • Fixed: AI won't start moving if its target destination is hard to reach
  • Fixed: AMV won't go through fences

- The AI will at least try to get closer to such destination and then check again for available paths. (If the destination cannot be reached at all, the AI won't even try)

- Wheeled armored units now go thru the fence instead of going around it.

13-11-2014

EXE rev. 128232 (game)

EXE rev. 128296 (game)

  • Fixed: AI in personTurret staying in the vehicle in combat mode
  • Added: setUnloadInCombat script command

AI at any cargo position (normal or firing position) should consistently disembark in combat. This default behavior can be changed by the setUnloadInCombat command (e.g. if you want the AI that is able to fire from its position to stay in the vehicle even in combat)

22-01-2015

EXE rev. 128976 (game)

DATA

  • Added: aiRateOfFireDispersion parameter into the base fire mode class with a default value of 1 to introduce basic randomness in AI firing patterns (to-be-tweaked)

Property that affects the randomness of delay between shots. Value sets the maximum of the range in which a random number influencing the delay between shots is generated. 0 means the delay between shots will be the same (with given actual distance). The bigger the value the longer delay can be generated.

ENGINE

  • Added: Detection of bullets flying close to unit

Similar to recent work on pathfinding, these commits are part of longer-term AI development. These changes are not yet configured to have any effect.

Once we're a bit more confident about the results, we'll provide futher details and specify the kind of feedback we're looking for.

  • Fixed: AI could get stuck planning paths from inside to outside of a structure (and vice versa) while in close proximity to the exit/entrance.

An attempt to fix http://feedback.arma3.com/view.php?id=20631 , in the end...not rly fixing it ;) We will give it another try.

DATA

  • Changed: AI detection distance of bullet hit/fly-by & grenade explosion

Basic setup of new properties in cfgAmmo in relation to the prev. entry. Please try in game how far the AI reacts to bullets flying by, to various bullets hitting the ground and explosions. And share your feedback or thoughts about expected detection/suppression distances in the AI thread. Also that would be the place to look for more info.

The new properties are suppressionRadiusBulletClose and suppressionRadiusHit

suppressionRadiusBulletClose defines how far the AI gets alerted by a bullet flying by. (only for bullets!) Value -1 disables the feature.

suppressionRadiusHit defines how far the AI gets alerted by a bullet hitting the ground or an explosion. Value -1 makes the game base the distance on the damage.

Tweaked: AI aiming error when it has lost sight of a target

This should improve situations when AI e.g. changes stance and because of that looses the line of sight to the target.

In such case - even if the AI still has good information about the target from other group members - the AI should no longer be able to put an aimed shot.
