How to add either/or requirements

A

Well-known member
Is it possible to create an ability that can have alternative requirements for entry?

For instance, is it possible to make Feat C require EITHER Feat A OR Feat B for entry?
 
Yes, for example:
In pre-reqs
validif (#hasfeat[featA_id] > 0)
validif (#hasfeat[featB_id] > 0)

This will be valid as long as one (or both) feats exist.

I'm also quite sure that | represents "or" in scripting. I just can't find something in my HL notes to confirm it.
 
You can also take advantage of the fact that #hasfeat[] will return "0" if false, and "1" if true, and add them together, and get the total:


As an exprreq, rather than a prereq:

#hasfeat[featA_Id] + #hasfeat[featB_Id] <> 0


Or, convert it into the full tags - skip the macro (this one also works in an exprreq:

tagexpr[HasFeat.FeatA_Id | HasFeat.FeatB_Id] <> 0
