Question for custom flaw

[Starkad]

I know that to add a flaw where a 19 strength is required, you'd put in 'Field' = 'reqStr'. But how would you add a flaw that required either a 19 str OR a 19 con?

i know it sounds odd but i believe you use the + sign, at least thats what i see in other examples and have used myself

You'd need to use a pre-req for this

validif (#attrvalue[aSTR] >=19)
validif (#attrvalue[aCON] >= 19)

In this situation if you used a "+" it would look for the a combination of STR + CON to be >= 19 and not either/or

so some times it is a combo and sometimes it does if 1 or the other is valid? i'll never get ahold of this coding. lol

in general the #hasability and similar macros are all tagis[XXX.?] checks they have a value of 0 or 1. So adding them together and checking for a result that is not zero is like doing an or statement in an expr-req. This only works with the tagis statement.

In some rare occasions you might have to do a validif (#hasability[] + #hasability[] = 2) as part of a pre-req, something like Either A and B, or C, but it's rare.

Using the pre-req the way I did means it checks to see if either line is valid.

Your way works when asking "Boolean" questions. A Boolean is special data type in programming that is either a 1 or 0 or True or False. Unless of course we are talking about Quantum Boolean variables but not in the mood to talk about cats.

So a "Boolean" question or "if" statement would be like do I have Feat A or Feat B as the answer is either "TRUE(1)" or "FALSE(0)". You have no other way of answering the question.

So what you where saying is if a pre-req said Feat 1 or Feat 2 is required you would:

#hasfeat[fFeat1] + #hasfeat[fFeat2] <> 0

The above in many other languages would like like this:

If #hasfeat[fFeat1] = BOOLEAN_TRUE
   or #hasfeat[fFeat2] = BOOLEAN_TRUE;
    //Here do something when we have either feats
else;
    //Here do something when we do NOT have either feat
endif;

The two sets of code above are doing the same bit of logic just HL has shortened the syntex really down. So each #hasfeat[] macro returns TRUE (ie one) or FALSE (ie zero) allowing HL to do simple math:
1) #hasfeat[fFeat1] returns 0 + #hasfeat[fFeat2] returns 1 (totals 1) will NOT equal zero so its "true".
2) #hasfeat[fFeat1] returns 1 + #hasfeat[fFeat2] returns 0 (totals 1) will NOT equal zero so its "true".
3) #hasfeat[fFeat1] returns 0 + #hasfeat[fFeat2] returns 0 (totals 0) will equal zero so its "False".
4) #hasfeat[fFeat1] returns 1 + #hasfeat[fFeat2] returns 1 (totals 2) will NOT equal zeros so its "True".

Hope that helps some.
