Spectate such bots:

New features:

16. FixCTFReturnOnlyAlternatePaths
- Fix select AlternatePaths on map with bReturnOnly AlternatePaths.

As result:
- bots not do dumb runs to inproper spot.

Work only for CTFGame and subclasses of it. Require AlternatePath bReturnOnly actors on map.

17. AvoidMoveToDead
- Remove MoveTarget if it is dead pawn.

As result:
- bots not do dumb runs to invisible dead enemies.

Mind explaining a bit more about #17? Maybe I haven't been paying attention.

It hard notice if you not use mind reader.
Usually bots jumps as monkeys and hard understand what and where, so such behavior goes unnoticed.

I observed this behavior in CTF games for bots who defends, but suspect it can be in other cases as well.

Bot wanna kill enemy. Bot see enemy close enough. Bot set Enemy as MoveTarget. Which make it reach destination for bot.
Bot kill enemy or this do someone else. (possible later cause bug).
Bot not check state of Enemy. bot just simply goes to dead Enemy. Which is hidden, in state Dying and basically just move invisible with same speed.
For humans actual view goes to head gibs which spawned on death and jumps on floor.
For bot change movement need external distraction or reach MoveTarget.

I see as bot chase dead enemy for 1 or 2 seconds, and after turn to wandering or roaming. Or bot reach dead or timer for movement out and MoveTarget updated.

Just tested it ...holly sheet those bots got some moves.
They certainly gave me a run for their money. First time I got defeated by bots and don't feel ashamed.

well done Buggie.

EDIT----------------
Now I feel the urge to remake my Northern Lights map fitting for vehicles.

Issue: Skaarj getting stuck
Reason: Bad code in OldModels.

Spoiler

OldModelssktrooperbot use next code for Falling state (Logging is mine):

Code: Select all

state FallingState
{
ignores Bump, Hitwall, HearNoise, WarnTarget;

  function Landed(vector HitNormal)
  {
    local float landVol;
log("DBG:" @ AnimSequence @ GetAnimGroup(AnimSequence));
    if ( GetAnimGroup(AnimSequence) == 'Dodge' )
    {
      if (Velocity.Z <= -1100)
      {
        if ( (Velocity.Z < -2000) && (ReducedDamageType != 'All') )
        {
          health = -1000; //make sure gibs
          Died(None, 'Fell', Location);
        }
        else if ( Role == ROLE_Authority )
          TakeDamage(-0.15 * (Velocity.Z + 1050), None, Location, vect(0,0,0), 'Fell');
      }
      landVol = Velocity.Z/JumpZ;
      landVol = 0.008 * Mass * landVol * landVol;
      if ( !FootRegion.Zone.bWaterZone )
        PlaySound(Land, SLOT_Interact, FMin(20, landVol));
      GotoState('FallingState', 'FinishDodge');
    }
    else
      Super.Landed(HitNormal);
  }

FinishDodge:
log("Start wait finish dodge Anim");
  FinishAnim();
 log("End wait finish dodge Anim");
  bCanDuck = true;
  Goto('Done');
}

So after do Dodge it run
GotoState('FallingState', 'FinishDodge');
And goes to

Code: Select all

FinishDodge:
log("Start wait finish dodge Anim");
  FinishAnim();
 log("End wait finish dodge Anim");
  bCanDuck = true;
  Goto('Done');

Which never end, because BotpAck.Bot in this state define

Code: Select all

    function AnimEnd()
    {
        PlayInAir();
    }

Which in this bot implement as

Code: Select all

function PlayInAir()
{
  BaseEyeHeight =  Default.BaseEyeHeight;
  TweenAnim('InAir', 0.4);
}

So this goes to endless call TweenAnim after it end, and FinishAnim never return.

I go implement next fix in Next SmartStockBots:

Code: Select all

    // try fix bug with stuck in air OldModels.OldModelssktrooperbot
    if (Bot.Physics == PHYS_Walking && Bot.Velocity.Z == 0 && Bot.AnimSequence == 'InAir' && !Bot.bAnimFinished) {
        Bot.bAnimFinished = true; // break wait in FinsihAnim
    }

With it loop break and it goes fine.
Since this check called only 10 times per seconds, there possibly additional delay up to 0.1 sec after real dodge end.
I think this OK.

Some authors (like @_21) make dirty fix of OldModels.u with replace
if ( GetAnimGroup(AnimSequence) == 'Dodge' )
to
if ( GetAnimGroup(AnimSequence) == 'Shielded' )
This make this if never run, so fall in loop not happen. But other related code too not run.

My fix must fine work with such fixed version too.

In general there must no but in such condition as
Bot.Physics == PHYS_Walking && Bot.Velocity.Z == 0 && Bot.AnimSequence == 'InAir'
So it must be safe.

Anyway if find any issues in upcoming release - report here.

Automatically merged

New features:

Local use:
After each load UT use Mod menu for activate loader. After that you can play any map (include campaign ladder) with this mutator (except network play on other servers OFC)

Improved ShortMovements. As result bots shortcut more paths and dodge in more cases.

Just double checking. Is XC_Engine required to use SmartStockBots?

There appear some warnings in the log file, maybe you can fix them:

Code: Select all

ScriptWarning: SSBClearBotOnDeath CTF-Face-SE.SSBClearBotOnDeath0 (Function Engine.PlayerPawn.TeamMessage:000A) Accessed None 'Player'

Posted: **Sun Jan 29, 2023 8:19 pm**

New features

19. ReportEnemyFlagCarrierLocation
- When bot report about "Enemy flag carrier is here." appear second message in form "Enemy flag carrier is here: %Location Name%"

As result:
- bots report to you where actually flag carrier is. Not where they be when see it.

- Fix fall from edge/into hole in some case for dodge.
- Fix flood in log.
