At present, the only why to do this is with triggers.

<!-- A technology condition to check -->
<attachment name="conditionAttachmentUnitsListTech" attachTo="Player" javaClass="RulesAttachment" type="player">
   <option name="techs" value="IncreaseUnitsList" count="1"/>
</attachment>

<!-- Then the trigger -->
<attachment name="triggerAttachmentUnitsListTech" attachTo="Player" javaClass="TriggerAttachment" type="player">
   <option name="trigger" value="conditionAttachmentUnitsListTech"/>
   <option name="unitType" value="unitCreator"/>
   <option name="unitAttachmentName" value="UnitAttachment"/>
   <option name="unitProperty" value="createsUnitsList" count="-reser-2:aCreatedUnit"/>
    <option name="uses" value="1"/>
    <option name="when" value="after:playerTechActivation"/>
</attachment>

The downside is that any Player the uses 'unitCreator' now has the ability to create 2 createdUnits per turn.

@beelee

techAbilityAttachment is limited to what is listed in POS2. Unless of course you dig into the engine code. I can do hitPoints, transportCapacity, and almost combatOffenseEffect / combatDefenseEffect for territoryEffect.

So much fun!

I hope you are going to get those into the game so the rest of us mere mortals can use them!

Hacks. I'm really making a mess of things. I just learning how the engine works.

It's a fun hobby. But we'll see.

Do you know how I can have techs be directly purchasable? And how I can affect the price to be different resources than just PUs?

wc_sumpton

@ff03k64

Check out 'Age of Tribes' by @Frostion. All the Tech/Upgrades are purchasable in this great map!!

With this code for my trigger.

			
			<attachment name="conditionAttachmentMedicPromotion" attachTo="XCOM" javaClass="RulesAttachment" type="player">
				<option name="techs" value="medic_promotion" count="1"/>
			</attachment>
			
			<attachment name="triggerAttachmentMedicPromotion" attachTo="XCOM" javaClass="TriggerAttachment" type="player">
				<option name="trigger" value="conditionAttachmentMedicPromotion"/>
				<option name="unitType" value="medic"/>

				<option name="uses" value="1"/>
				<option name="when" value="after:playerTechActivation"/>
			</attachment>
			```
I really can't figure out how the "unitAttachmentName" line is supposed to work.

beelee

I think you need this :

instead of this:

here's an example

ff03k64

After fiddling with it, does it even need that line?

beelee

@ff03k64 idk never tried it without it

wc_sumpton

@ff03k64

The value needs to have a capital 'U' value="UnitAttachment". It is the same value as in the javaClass = value.

Cheers... (With a capital 'C')

ff03k64

edit: nevermind, figured it out. needed xcomTechActivation, not playerTechActivation

@wc_sumpton

			<attachment name="conditionAttachmentMedicPromotion" attachTo="XCOM" javaClass="games.strategy.triplea.attachments.RulesAttachment" type="player">
				<option name="techs" value="medic_promotion" count="1"/>
			</attachment>
			
			<attachment name="triggerAttachmentMedicPromotion" attachTo="XCOM" javaClass="TriggerAttachment" type="player">

				<option name="unitProperty" value="createsUnitsList" count="-reset-2:bandage"/>
				<option name="when" value="after:playerTechActivation"/>
			</attachment>

No longer throwing errors. So far as I can tell it isn't doing anything though.

After perusing this for a bit, it looks like he does the tech purchasing by buying a unit, and then if you have that unit, you are allowed to build the associated tech? So it isn't really using the games tech system? Does that sound right?

wc_sumpton

@ff03k64

   <option name="unitAttachmentName" value="UnitAttachment"/> <!-- No count value -->
   <option name="when" value="after:XCOMTechActivation"?> <!-- Needs the name of the Owning Player's (XCOM) Tech Activation sequence -->
   <option name ="uses" value ="1"/> <!-- added to prevent the trigger from firing over and over again.

The 'when' option determines during what sequence the trigger will fire. Also add a "uses=1" option to prevent the trigger from firing over and over.

Cheers...

wc_sumpton

@ff03k64

That is how 'Age of Tribes' handles purchasing of tech. Yes

That's unfortunate, I guess if i do some of my techs that way, i probably want to do all my techs that way then?

Does that make sense?

wc_sumpton

@ff03k64

No. You can purchase, and you can develop with the Tech Roll. You can do different Techs, or you can do the same Tech. Just use trigger to remove developed Technologies from the purchase window. And activate a purchase Tech, so the game can remove it from the development roll.

Cheers...

ff03k64

@wc_sumpton Well, I probably don't want the random tech rolls anyway. I guess that would be the big thing anyway.

Frostion

@ff03k64 You could also take a look at the Star Trek map, play and test out the tech system. It is a tech roll system where you pay for rolls with PUs (I would like to call the rescues “Science”, not PUs, but the engine does not allow it as I remember).
If you play go after the blue dots on planets (PUs/science) and you will soon be able to roll/buy tech. Or you can cheat buy edit and give you nation PUs

ff03k64

@Frostion I actually tested that a little. I edited myself 99 planets! I find myself liking the tech model from age of tribes better. My biggest question about techs now has become do I want to display the researched techs like your backpack in your Warcraft map.
