Why is this better than including "IsWeapon.wRapier" in the initial search expression? such as:

searchexpr = field[usrChosen1].chosen.tagids[IsWeapon.wRapier]

I'm still very much a novice at this, so I'm not trying to argue. Just trying to understand.

Making a guess but I think its the field[usrChosen1].chosen that is throwing you. That "field" means we have a dropdown list of Picks/Things that a person selected. Sense we do not know "which" weapon was chosen (in example we assumed Rapier) but it could have just as easily been longsword or greatsword. In other words the dropdown has a choice of weapons from one to hundred.

So we need to pull a "Tag" group from the weapon chosen without knowing what the "specific" tag is. Then use that tag to find all Live Picks of that weapon on the hero which is what the foreach loop is doing. Sense the "search expression" field holds all the logic of which Picks to select we do not need to test for anything in the foreach loop.

My initial comment was to not use "thingid.?" tag group for the search expression as a Pick can only have ONE thingid.? group on itself. Where IsWeapon.? group can be assigned many times to a Pick. Which allows flexibility.

Hopefully that helps.

OK, yep. You were exactly right on the point I was missing. I had to go back and read the original post to put it all together, but I got it now. Thanks.
