Ok, so i figured it out in a round-about way.. actually took me a bit because i neglected to notice the file looking me right in the face called
attributemodifier.xmlIf anyone else is looking for this info the best thing I can say is to take a look at the
GDIZoneTrooperSquad.xml specifically the lines where it states..
<AttributeModifierUpgrade
id="Upgrade_ScannerPack_02"
AttributeModifier="ZoneTrooper_ScannerPack">
<TriggeredBy>Upgrade_ZoneTrooperScannerPack</TriggeredBy>
</AttributeModifierUpgrade>
this in conjunction with the listing in
AttributeModifiers.XML under GlobalData, and the
AssetTypeAttributeModifier.xsd in the Mod SDK\Schemas\xsd folder.
should be enough to get you squared away...
and thanks again Madin
