            totalAirUnits = totalAirUnits + AIKnownUnitCount(player, a, c_TU_Banshee);
            totalAirUnits = totalAirUnits + AIKnownUnitCount(player, a, c_PU_VoidRay) * 2;
            totalAirUnits = totalAirUnits + AIKnownUnitCount(player, a, c_PU_Carrier) * 4;
            totalAirUnits = totalAirUnits + AIKnownUnitCount(player, a, c_ZU_Mutalisk);

        a = a + 1;
    }

}

Does Grab include structures currently under construction? How about AIKnownUnitCount?

AIKnownUnitCount counts units under construction too; if you want something more specific use TechTreeUnitCount with one of the following flags:
const int c_techCountQueuedOnly         = 0;const int c_techCountQueuedOrBetter     = 1;const int c_techCountInProgressOnly     = 2;const int c_techCountInProgressOrBetter = 3;const int c_techCountCompleteOnly       = 4;const int c_techCountIncompleteOnly     = 5;

Cool.

I'm currently needing a function that returns the free available food supply with two conditions:

Now -- the number of free resource from hatch/lair/Hive + ovies already completed.
Soon -- Now + number of ovies in queue or already in production.

I'm using this to test a script that will only spawn lings when necessary, and depending on the number of what target it needs to counter and the counter value for ling vs that specific target in question.

Also, one question, will two while blocks run simultaneously?

Say,

while(A) {
   do(x)...
}
while(!B) {
   do(y)...
}

Will do(x) and do(y) run simultaneously?

No like that. It will run the code in the order it's typed. while(a) will run, finish then while(!b) will run.

You can however put

while(a) {
    while(!b) {
    }
}

It's like this:

//begin: Bane Defense
    AISetStock( player, 1, c_ZB_Hatchery_Alias );
    AISetStock( player, 10, c_ZU_Drone );
    AISetStock( player, 2, c_ZU_Overlord );
    AISetStock( player, 1, c_ZB_SpawningPool );
    if ( AITechCount(player, c_ZB_SpawningPool, c_techCountQueuedOrBetter ) == 1 ) { //we've started pool
        AISetStock( player, 12, c_ZU_Drone );
        AISetStock( player, 1, c_ZB_Extractor );       
        AISetStock( player, 15, c_ZU_Drone );
    }
    if ( (AITechCount(player, c_ZU_Drone, c_techCountInProgressOrBetter ) >= 13) &&
         (AITechCount(player, c_ZU_Drone, c_techCountInProgressOrBetter ) <= 16) &&
         (AIHasRes (player, 150, 0) == true) )
    {
        AISetStock( player, 1, c_ZU_Queen );
        AISetStock( player, 3, c_ZU_Overlord );
        AISetStock( player, 12, c_ZU_Zergling );   
        AISetStock( player, 1, c_ZB_BanelingNest );       
        AISetStock( player, 16, c_ZU_Drone );
    }
    if ( (AITechCount(player, c_ZU_Zergling, c_techCountInProgressOrBetter ) >= 4) &&
         (AITechCount(player, c_ZU_Zergling, c_techCountInProgressOrBetter ) <= 12) &&
         (AIHasRes (player, 250, 0) == true) )
    {
        AIDefaultExpansion(player, c_ZB_Hatchery_Alias, 12000, 6000, c_expandDefault);   
    }
    if    ( (AITechCount(player, c_ZB_BanelingNest, c_techCountCompleteOnly ) == 1) ) {
        AISetStock( player, 6, c_ZU_Zergling );
        AISetStock( player, 8, c_ZU_Baneling );
    }
   
    if ( (AITechCount(player, c_ZB_Hatchery, c_techCountInProgressOrBetter ) == 2)  &&
        (AITechCount(player, c_ZU_Drone, c_techCountCompleteOnly ) <= 18) &&
        (AIGetTime() < 300)    )
    {
        AISetStock( player, 8, c_ZU_Zergling );   
        AISetStock( player, 8, c_ZU_Baneling );
        AISetStock( player, 10, c_ZU_Zergling );
    }

I wrote this without the funcs yet, which I believe you guys can do. Funcs that are conditional which will run in parallel.

From testing, the script should either choose to make banes immediately or lings, or skip them all together if the enemy had no zealots, right? That's where the while comes.

I want the AI to enter a while and stay there until a break is called. And once that while has been entered, a key will be set so the next while will not be true anymore.

Before each while, conditions tested and the script will parse multiple ifs repeatedly until a while condition is met. Once in a while, at some cases, a key will be set and break called so as to call the other while.

All this will loop over and over, just as a state does, and might even leave a state early and move to MidGndA or B. All depending on the conditions.

From the above example, we can later create a code that has one main, and two conditional states it will enter. This so called states are the ones in the while statement.

So for example, while the protoss player is maintaining a number of zealots, it will enter the while and keep TrainZerglings(UnitToCounter, Min, Max, PriorityKey).

So it's probably going to look like this:
returned 1 -- minimum is reached
returned 2 -- maximum is reached
returned 3 -- we cannot try min, we cannot try max, we're not needing this.

while (TrainZerglings("Zealot", 3, 7, 8 ) != 3) and some condition is true here) { //we are facing 1-7 zeals, and we've not trained zerglings 1x4 (minimum which returns 1) to zerglings 7x4 (max which returns 3)

     [do stuff here]
}

if (we have more than 6 lings complete and TrainZerglings(..) >= 1 and != 3 and some condition here is true) {
     while (TrainBanes("Zealot", 1, 3, 10) !=3)) {}
}

So, as you can see, the script should jump back and forth from each other and maintain a number of lings, then morph them to banelings, etc, until everything is satisfied.

Something like this. Haven't put a lot of thought yet in implementation, since I'm still trying to figure out the thinking process and loop holes of ZvP @ < 5:00 mins.

So far though, the above will most likely be needed should it make the AI more dynamic.

It does. My above post is really not refined nor exactly useful (sort of inductive). They're vague concepts still, as I'm yet trying to get a handle on the whats that gets swapped around within the first 5mins of the game.

Anyway, I'll post what I find.

Brilliant. I'm currently focusing on the AI in a defensive mode. It wants to tech to lair asap, and use minimal expenses on defense units, and will build them only when necessary. Once it get's lair, it starts two things:

want to 3rd expo, while harassing, and building up an offensive army.

Before, I get to that though, I'm working on the script for the early game, and give it priority shifting. I'm trying to write code, which I want to be as dynamic as possible, and can be reused later up in the tiers where multiple options, and more data are involved.

True. After testing, while kind of makes the game into stop motion. Ifs work better.

Do you guys know how the galaxy files interact? where do we define global variables, which one gets executed, which ones are just libraries, etc.
