Counting Feats

[AndrewD2]

A feat I'm entering adds 2 HP for every feat of a specific category (Arcana in this case).

I figure I just need to count the fCategory.Arcana tags, multiply by 2 and += them to HP but I'm no sure how to do the tag counting part.

I'm thinking:

var count as num
foreach feat where tagis[fCategory.Arcana]
count += 1
end

count *= 2
container.child[Totals].field[tHP].value += count

I know my syntax is very likely wrong I just wanted to write out my idea and see if I'm on the right track.

Thanks,
Andrew

On the Class Level tab (not the Class tab), copy the Loremaster class - one of the prereqs on that needs to count feats by category.

so I could do something like:
var count as num
count = tagcount[fCategory.Metamagic] * 2
container.child[Totals]field[tHP].value += count

My advice is to follow the HL standard and do

field[abValue].value += tagcount[fCategory.Metamagic] * 2
hero.child[Totals]field[tHP].value += field[abValue].value

The big advantage of using field[abValue] is that you can affect changes to this feat then from other Things. What if some feat or ability gives a -2 HP for taking this feat.

You could do

hero.childfound[ID_OF_FEAT].field[abValue].value += -2

By not using abValue you lose out on that ability.

I get an error using that:

Hero Lab was forced to stop compilation after the following errors were detected:

Syntax error in 'eval' script for Thing 'fRPArcaneB' (Eval Script '#1') on line 7
-> Invalid child transition syntax used

[AndrewD2]

Also I'm already using abValue in this feat, so I think I just use abValue2 but I can't remember.

ShadowChemosh, as long as you're talking about best practices, I'd suggest using -= 2, rather than += -2.

Also remember that herofield[] is a shortcut for hero.child[Totals].field[], and #value[] is a shortcut for hero.childfound[].field[abValue].value, so you can cut down the typing required for that code even further.

AndrewD2, the error message refers to line 7. I recommend you copy and paste line #7 here (or paste your whole script, empty lines and all, if you can't figure out which one is the problem). You've probably got a typo, but without seeing the code, we can't see what it is.

[Mathias]

Actually, I think I can see it, if you copied ShadowChemosh's script exactly and then modified it - he forgot a period inbetween hero.child[Totals] and field[tHP].value

[AndrewD2]

Ok so I got it working ... kinda

~ Add to abValue first so outside things can adjust us
field[abValue].value += 1
~ add to the pool total
#trkmax[trkArcaneP] += field[abValue].value

field[abValue2].value += tagcount[fCategory.Arcana] * 2
herofield[tHP].value += field[abValue2].value

is the whole eval script.
I was running it at post-attributes 10000, but I've tried it in most every other phase and it only ever adds 2 HP even when having 4 other Arcana feats. Am I missing something?
