Checking feats

[AndrewD2]

I'm working on a feat that has a requirement of (roughly) "1 feat from this category that causes damage".

Do I need to go through at do a #hasfeat check for all the feats that meet that requirement, or can I do something like assign a tag to all those feats and then check for that tag in the prereq?

Thanks,

Andrew

You could do it either way. The custom tag option seems more elegant to me.

If you decide to go with a custom "Causes Damage" tag on the feats, you'll either have to have the feat forward that tag to the hero, and have the pre-req check there. OR the pre-req will have to foreach through all the feats on the hero of this category, looking for one with the tag.

Ok, I think I'll go with the foreach route. I think that'll save a lot of scripting on all the other feats. But I'm honestly not sure of the syntax for the foreach loops. If I named it Custom.KiDamage it would be something like:

foreach pick in hero from feat where "Custom.KiDamage"
@valid = 1
nexteach

Capitalization's important.

foreach pick in hero from Base[B]F[/B]eat where "Custom.KiDamage"
  @valid = 1
  nexteach

Foreach loops have several parts to them

foreach PICK/THING/BOOTSTRAP in HERO/CONTAINER/GIZMO from SOMECOMPONENT where "TAG EXPRESSION" sortas SOMESORTSET

Only the first 2 parts are strictly necessary, but the more specific you can be, the less computational power you'll waste. I'd say always at least limit it to a particular component.

To see what components are on a particular type of pick, Enable Data File Debugging, add something of that type, and right click "Show Debug Tags for..." There are usually several "component" tags lumped together, and by looking at those you can see that all feats have the BaseFeat component, while the Feat component doesn't exist.
