Trying to figure out how to do something on cMUD
 
I'd like to capture a database titled "party", then have a positional notifier for party order number, then subset values of that positional. For example, party.1.name = cliff, party.1.hp = 2138, etc

I've been easily able to get proper regex to capture the variables but I'm not sure how to properly nest things into my DB variable such that I can accomplish what I'm after. If it's not possible with a single database, I could be willing to do something like party.1 = cliff, cliff.hp = 2138, but that seems clunky.

What's the best way to accomplish this that you've found

If you are hoping to have buttons or a status object updated with the values, then you want regular variables, not a dbVar.
Its a limitation of the implementation.

As for how you would go about editing a nested dbVar:

//first we get the current value in a local variable
$this=%db(@party, 1)

//then update the values for the nth party member
#ADDKEY $this Name Cliff
#ADDKEY $this HP 2138

//before we save the updated values back to our permanent variable
#ADDKEY party 1 $this

This process can be extended as many levels as needed.

Unless the party nth placement is relevant, i would just do it as:

$this=%db(@party, Cliff)
#ADDKEY $this hp 2138
#ADDKEY party Cliff $this
