On the Requirements Data Type I learned a bit of simple things by looking on the requirements of default units like Learn X Upgrade, Have X Unit, Use X Spell but some things requirements are a bit complex for me yet like Mothership Requirements. Somehow if i imitate this requirement i can make a unit only once, but i don't know how the nodes flow that made that requirement work. (what other nodes can "Constant" be applied?)

what i know so far (not sure if im right):
"USE" - anything that makes the button usable/restrict
"SHOW" - anything that makes the button appear/disappear on command card

Now lets say i want to make a requirement that i can only research Banshee Cloak if i have at least 1 SCV, just 6 marines, a fusion core, and siege tank research and combat shield upgrade are completed. how would it look like?

btw i've tried using the Expression view and...

Here is your requested requirement:


Please ignore the AND in the siege tank tech, it's my mistake and I don't want to fix and screenshot it again.

Basically it's like triggers. It uses logical connectors to compute if the result of the requirement is false or true.

Your application of USE and SHOW is correct.
If SHOW is empty, it is always shown.

so that's how to make a multiple requirement for a certain upgrade, thanks

so the "And" node are used to make multiple requirements?

AND means that everything within the AND needs to be true to make the AND return true. If one is false, AND will return false.

AND and OR in trigger conditions work the same way.

does using OR node looks also like that? example making Marauder applicable whether i have techlab or reactor, anyway here's my sample (not sure why the image looks crappy though ):

and how do you make the requirements nodes have its own window? mine was stuck on the data module?

just wondering what's the diffrence of Alias_Techlab to Techlab and the rest of Alias_Structures?

It should just be "Or" and then the two Count Unit requirements after it, if I remember correctly.

I'm not sure what you mean by "have its own window", but I usually have the "Display Object List as Tree" button unpressed as that just adds unnecessary organization and folders, and I have the "Table View" button pressed so you can see all the info for the ability/unit/behavior/etc. at once. "Show Advanced Values" and "Show Field Type Names" are great to have pressed, as well as "Combine Structure Values". Maybe that combination will get you what you want.

so if i placed 3 Count Upgrades (State: Complete) nodes under "OR", that requirement only needs at least one of the 3 count upgrade competed then?


Im talking about Ahli's image that the requirement nodes was separated from the data module. anyway reading your reply leads me to the answer, Ahli uses Table view while mine's were in detail view. I use Detail View because for me its more organized and "noob-friendly".

Correct.
OR requires only 1 of its containing statements to be correct
