Technology & Tech Trees - how to make one tech unlock another tech

Technology & Tech Trees - "how to make one tech unlock another tech"?
this seems to have been asked in different ways over the years but i failed to find a clear answer. i'm guessing that there is no simple way of doing this with the standard tech system - just the age of tribes way... but hopefully i'm wrong?

is there maybe a way to make unlocking a special unit require two techs?

edit: dammit, thought i was making this in the map making sub... not allowed to delete so apologies for putting it in the wrong place... although if i'm correct about it being impossible then i guess it is a feature request...

More information is needed to understand what you are trying to accomplish.

That being said, tech can be handled with triggers. In PoS2:

<attachment name="conditionAttachmentAmericans4" attachTo="Americans" javaClass="RulesAttachment" type="player">
   <option name="techs" value="jetPower:warBonds" count="2"/>
</attachment>

Reads the jetPower and warBonds techs. Then triggers can be designed to read this comdition:

<attachment name="triggerAttachmentAmericans8_TacticalAirUse" attachTo="Americans" javaClass="TriggerAttachment" type="player">
    <option name="conditions" value="conditionAttachmentAmericans4"/>
    <option name="support" value="supportAttachmentFighter"/>
   <option name="uses" value="1"/>
</attachment>

This trigger is designed to fire after both jetPower and warBonds tech have been granted to Americans.

As I said, more information is needed to understand what you are trying to accomplish.

context:
i'm still modding steampunk advanced.
there is a tech "armour" that unlocks multiple units - different tanks plus some rather uber monstrosities. i would like to separate off the most OP one [heatrayTripod] into another tech that only becomes available after one has gained "armour".

cameron

does the trigger you suggested just give them the tech? or make it available for future research?

@cameron

The condition checks for given tech. The trigger grants a unitSuppportAttachment,

To give a tech with triggers use the "tech" key word, to add remove tech from development use "availableTech".

Cheers...

finally got this working. dunno what i did wrong the first time... sometimes you just need to delete it and start again.

thanks for the help.
