What's reliable way to detect if unit has antiair weapon?

[slogic]

Current algo is:

Code: Select all

		if (weapon->def->tracks && !weapon->def->waterweapon 
		&& !weapon->def->stockpile && !weapon->def->canAttackGround)
			return true;

But flak weapons are skipped. I have no access to "toairweapon" tag of weapons.tdf file.

I was thinking about checking ballistic=1 & turret=1 but this is wrong.

Note that i won't parse text resources.

Hm, i noticed all fbi files of anti-air units in BA have tags like these:

Code: Select all

  sightDistance=475;
  airSightDistance=900;

So, air sight distance of all anti-air units is 1.5x-2.x higher than usual sight distance. Can be used as additional trigger but also may give false positives.

Dunno if you can do it this way, but you could check the target categories of the weapons for "VTOL". *Shrug*

No, i can't: http://springrts.com/phpbb/viewtopic.php?f=15&t=22988

I just profiled (ud->airLosRadius / ud->losRadius) expression for all registered anti-air units and always get values < 1.0. Very strange. Looks like they are expressed in different items.

EDIT
From some lua widget:

Code: Select all

   unit->realLosRadius=(int) (ud->losRadius/(SQUARE_SIZE*2));
   unit->realAirLosRadius=(int) (ud->airLosRadius/(SQUARE_SIZE*4));

EDIT2
Actually more complicated :/

Code: Select all

	losRadius = udTable.GetFloat("sightDistance", 0.0f) * modInfo.losMul / (SQUARE_SIZE * (1 << modInfo.losMipLevel));
	airLosRadius = udTable.GetFloat("airSightDistance", -1.0f);
	if (airLosRadius == -1.0f) {
		airLosRadius = udTable.GetFloat("sightDistance", 0.0f) * modInfo.airLosMul * 1.5f / (SQUARE_SIZE * (1 << modInfo.airMipLevel));
	} else {
		airLosRadius = airLosRadius * modInfo.airLosMul / (SQUARE_SIZE * (1 << modInfo.airMipLevel));
	}

[slogic]

Based on my tests (SQUARE_SIZE * (1 << modInfo.losMipLevel) / modInfo.losMul) = 32. I don't understand where modInfo.losMul & modInfo.losMipLevel are set by game developer? Or are they constants really?

modInfo(.lua) | modRules(.tdf)

[slogic]

Thanx. Found at mod rules. Also found an outdated information that is was in sensors.tdf files long ago.

Well, i think i'm in a deadlock again like with Spring category tags because modInfo is not accessible via Legacy C++ API.

I see no way to 100% detect anti-air units.

If you have have any persistence in your AI data you could train that stat by counting total air kills for each unitdef. Then pick a reasonable minimum threshold that avoids those occasional cases where a plane got caught on the ground.

[slogic]

Training is bad for constantly modifying games.

In my ancient AI code I was detecting AA weapons using weaponDef->onlyTargetCategory.
It was before AI interface rewrite so no idea how the exact code would look like now.

[slogic]

I wanna use it too but it is of integer type (not string) & contains flags to which i have no access: they are not static.
