What custom base units do you add to alpha(x).txt?

[BFG]

A lot of the more experienced players know that SMAC/X's AI can be improved simply by adding new base units to alpha.txt or alphax.txt.
I'd like to start a thread where everyone posts the new units they use (or used to use) and, if it's something extremely unique or nonobvious, the benefits of using those units.

I figure we can all benefit from checking out each other's ideas.  I'll go first.

Hmm, I really thought this topic would get a bit more attention.  Maybe I'm mistaken, and not very many people add new units...
If that's the case...then what would you add to bolster the AI, if you could?

[Green1]

As far as myself, I have only tinkered with the Alphax to get rid of that annoying mandatory retirement year since I like playing with tech stagnation and of course to add some wierd custom faction. The MPers here probably do not because you would have to switch out the .txt each match. I probably should look into making batches of good units for the AI, though.

I have, however, lurked around a bit and have seen this come up before. The ONE most common thing folks tend to add is probe team foils.  Almost all human players use them, the AI would benefit as well.

[Kilkakon]

Yes probe team foils are very common!

I don't have a lot more to say due to my replacing of so much in my game, but yeah, I can vouch for the naval probes.

I try to stick to ingame costs for units, which I think you've not done? Interesting idea though, adding cheap high chassis versions of all the non-combat units. I'll try it out sometime.

[BFG]

I try to stick to ingame costs for units, which I think you've not done? Interesting idea though, adding cheap high chassis versions of all the non-combat units. I'll try it out sometime.

Actually I've got them all set to autocalculate, so these are all at in-game costs too.

This brings up another question: what are the rules, exactly, for AI designing of units?  I thought that the AI could upgrade offense/defense, but not change chassis, as they gained new tech.  That is, new chassis have to be specified in alphax.txt.  Similarly, Probe Teams, Colonies, and other nonoffense units have to be specified.  But what about things like Deep Radar?  Is the AI capable of adding that at the same time that it upgrades offense/defense?

AFAIK, the units designed by the AI are the same as those designed for the human if the Design units automatically option is selected.

Most of these modifications are due to Darsnan and are intended to help the AI. I don't build any of the custom units when playing as that would tend to negate the attempt to help the AI.

Two notable changes:

1. Formers are available with no tech prerequisites. This benefits those AI that tend to put off researching CentEco.
2. Many early units, including Colony Pods and Formers, have Amphibious Pods. This ability allows them to move from a sea base to an adjacent land tile. Especially beneficial for the Pirates.

[Lord Avalon]

Petek, the following units have longer lines than the others:  Scud Missile, Attack Carrier Mk2, Seawolf Mk1, Seawolf Mk2, James Bond.  Is it just a matter of too many zeroes at the end, or is it something else?


Edit:  I believe I have found the answer in this Alpha/x Guide:

Special ability flags for the unit. These are 26 binary signifiers (either 1 or 0). A 1 (one) indicates that the unit has a specific special ability. The Scout Patrol has no special abilities, hence all flags are set to 0 (zero). To add a special ability: Change the correct 0 to 1. Changing the first 0 to 1 adds the dissociative wave special ability; changing the fourth 0 to 1 adds the non-lethal methods special ability etc. (see Table 6, Normal). Note that there are only 26 binary flags, although there are 29 special abilities. To add the missing abilities to a unit simply add 3 more flags (3 zeroes) at the beginning of the line. The first 3 flags represent these missing abilities (1st flag is Algorithmic Enhancement, 2nd flag is Fuel Nanocells and 3rd flag is Marine Detachment. See Table 5, Extra), the last 26 flags represent the normal/default 26 abilities.

[Petek]

Yes, I was just about to cite the same source!

[BFG]

Heh, that's part of the reason why I asked in another thread if additional, undocumented abilities are present in the game's programming!  We know about 26 (29 in SMAX)...but are there any more, perhaps that were programmed but never used?

[Lord Avalon]

Petek, if I'm reading things correctly, it seems the Cruiser Probe Sub lacks 3 zeroes at the end.  Also do Nerve Gas Pods do anything for a probe unit (see Probe Bug)?

Yes, something's not right. I don't build these units, so never noticed a problem. I'll try to find where Darsnan discussed his changes. Thanks for pointing this out.

Heh, actually the game would read this correctly, assuming it's alphax.txt instead of alpha.txt.  The three missing zeroes would be on the right end, and omitting them is just fine.  In fact you could shave two more zeroes off and still get the same units.
That said, I find it's always easiest just to use 29 digits every single time.

I'll have to compare the list you've got to the one I've got.  While I prefer to give the AI units I would also build, and to make them accessible at the "correct" position in the tech tree, several of these do look intriguing.
In fact, I'd love to get a "library" put together of all the custom units the people on these forums have created.  It'd be a great way to share ideas.

And I'm still waiting to hear from one of the guys who's looked at the code, to see if there's any nonimplemented abilities we could start using!

Per the Alphax Guide, the optional three zeroes are at the beginning.  So as I read it, the Cruiser Probe Sub has Amphibious Pods and Cloaking Device.  Adding three zeroes to the end results in Deep Pressure Hull and Air Superiority (but the latter is wrong, too - shouldn't it be AAA Tracking, which is two spots before Deep Pressure Hull?).

Edit:  BTW, alpha.txt only has 24 special ability flags.

[BFG]

Hmm...I could very well be misreading it.  There's one way to tell: see what happens in-game

On another topic, we're missing two VERY obvious units.  Have you ever had the AI use a tectonic or fungal payload?  I haven't.  The reason for this: those are AI plans 13 and 14 respectively.  But those plans aren't documented in the #UNITS section, and no AI units exist for those payloads.
