[Dev] Determining length of array-like attributes

Additional resources in the OGL 5E character sheet are accessed using identifiers like these: repeating_resource_$0_resource_left repeating_resource_$0_resource_right repeating_resource_$1_resource_left repeating_resource_$1_resource_right How can I determine if there are any, and in that case how many of these are present? I can access the field directly using: getAttrByName(charId, 'repeating_resource_$0_resource_left'); However, this logs an ERROR to the console if there are none.

You'd use the findObjs function here:&nbsp; <a href="https://wiki.roll20.net/API:Objects#findObjs.28attrs.29" rel="nofollow">https://wiki.roll20.net/API:Objects#findObjs.28attrs.29</a> to get all te attributes of the character, then filter down to those in the format&nbsp; repeating_resource_ (id) _resource_left That'll give you all the rows, and you can extract the ids. The actual row ids for repeating section are UUIDs, which look something liKe -35GHTU6445 &nbsp;- you need to use that format for the id for most operations. Once you have an array of the ids, you can do whatever you need to.

Thank you, that makes sense.
