Test: AI has no sense of using leaders at all

[onedreamer]

Not always, it depends on the first unit the AI puts in.As long as there are faster units available for the second and third unit there is no problem, but the AI won't fill the army complete, if the first unit is one of the fastest available (because of the bonus movement, which gets added)

Uhm... no. From my experience, the AI just puts a unit in the army and that's it. It won't add more even if they have higher movement than the army.

This is what happens (in C3C of course) from my games experience:

It gets even better, if you make an army spawning wonder, the AI refuses to fill them up!

[...]

they put one unit in some of them and left them in the city.

It won't add more even if they have higher movement than the army.

Exactly. It has to have the same movement as the Army; so Infantry and Cavs do not work. And, if it has several Armies available, it will fill one unit into each before filling up the first one.
But with proper unit selection, the AI will fill and use their Armies very well.

Well, as someone who first discovered this behavior (and tested) I can say one thing for certain:

-AI will always add frist offense unit into the army.
-AI will add other units only if their movment is equal or greter then movement of army

So if you have one swordsmen in army, only horseman or faster unit can be added, since army itself with one swordsmen already has movment of 2.

If you have one Cavalry in the army, it won't be filled with other units ever, since army has movment of 4 and there are no other units with movement of 4 or more in normal game.


This is a BUG, since be AI logic was apropriate before C3C, when armies had same movment as units in them.
It's just that someone form BreakAway or Firaxis forgoteen to upgrade the code.


So we have too bugs, one with AI inablity to use leaders to make army and another with faulty AI logic of filling the armies.

As far as I remember having infantry army and adding the cavalries will work.

Have seen lots of AI Armies during testing RaR, but they never filled in a move 3 unit after joining a slow-mover first, always a unit that matched the Army speed exactly. That, of course, doesn't prove anything, but unless someone shows that >= works, I'll continue to believe it has to be equal.

I just tested that (and this time it is a valid test ) by giving the AI an army, four swordsmen and four horsemen with movement modded to 3. The AI did fill it's army with one swordsman and two horsemen with movement 3. So this clearly shows that the >= system works.

Ok, convinced.

What if they can choose between move 2 and move 3 units? Any preferences?

 

[Theoden]

I also made a test on that (couldn't resist ) I assume you mean units with move 2 and 3 but the same A/D values

The AI was given a single army and the following units (some are modded):

4 warriors
4 spearmen
4 swordsmen
4 archers with move 2 and bombardement removed (which means that they are like horses in epic game)
4 horsemen with move 3 and cost reduced to 20 (reduced it just to make sure the only difference between archers and horses were the move)

warriors and spears were just included to give the AI the oppurtunity if they were stupid enough


I ran the test 10 times and the results were:

1: sword, archer, horse
2: sword, horse, horse
3: warrior (really, the AI did it ), archer, horse
4: sword, archer, horse
5: archer, horse, horse
6: sword, archer, horse
7: warrior (again ), archer, horse
8: sword, archer, horse
9: archer, horse, horse
10: sword, archer, horse

The conclusion for this test is:
the AI doesnot always put the strongest attacker in the army first
in the test all the armies included at least one horseman

I find it very hard to find out what the AI's preferences is, especially because it loaded a warrior into the army two times.

I guess it just circles through the units, assigns the first couple as defenders, and then fills in one into the Army.
Thanks for testing, Theoden!
