validate spell area

[mbran01]

I am trying to create a metamagic feat that requires the spell to have an area. I see that there is a field called sArea, but I can't figure how to validate it. Any help in that area would be great. I was working along these lines.

Thanks

validif (component.BaseSpell.field[sArea.?] <> 0)

Do you mean an area of effect for the spell?

 

[mbran01]

Yes, the area of effect (20-ft radius, 15-ft cone, etc.)

"sArea.?" is a tag not a Field. To get started think of fields as what holds a numeric value and a tag as words separated by a period.

So you can do ".tagis[sArea.?]". That will resolve as true if the spell has any Area Tags.

If you want to be valid for a specific area, assuming Cone 15ft is 15ft, you would look for ".tagis[sArea.15ft]". I am no where near HL so I can't find the actual sArea tags that are valid but you will be able to see them on the spell Thing itself.

I when I use ".tagis[sArea.?]" I get a group not definded error. Any thoughts on that.

Area is recorded on a spell in a field, it doesn't actually have a tag group associated. If your Metamagic needs an area, you can check if the area field is empty, and if not make the selection valid. Like so:

validif (field[sArea].isempty = 0)

You might have to transition from the MM to the container (the custom spell) to check the field, look at some other MM for how to do that.

Uh, so dumb question. How do I transition to the spell from the MM?
