The resource/time costs of units are to be found in the Abilities section, under their respective production building's Train ability. For example, Terran Infantry costs can be found in the Barracks - Train ability (in the Info fields).
Exactly, just double click on the "Info +" Data under Abilities->Barracks - Train and then double click on the ability you want to change the cost of (scroll down...)
Any idea how to change the requirements of Structures? in the same window that you edit resource costs it shows what it requires, but there doesn't seem to be a way to edit it from there.
Let's say you want to change the requirements for the "Missile Turret".
In the Data Editor go to Abilities -> SCV (Build)
Double click on the "Info +" field
Double click on "Build Missile Turret"
Now a little down the way you see "Requirements".
You can click on the little red x below the list to clear all requirements.
OR you can choose another requirement available.
OR you can write your own requirement and choose it here afterwards.
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
