Ok, I've got something for you to try. CAVEAT: this will overwrite your existing attributes! You may wish to try it out on a copy of your game. If you create any of the three attributes [ total_mana, current_mana, mana ], the script will create the others and fill all 3 with pertinent information the next time a spell is cast or a long rest is taken. It will also keep them up to date with the right values at any of those events and on restart of the API. Here's the code: on('ready',function(){
"use strict";
var
getManaTotalByCharacterID = function(charid){
return 0 +
(getAttrByName(charid,'lvl1_slots_total')*1)+
(getAttrByName(charid,'lvl2_slots_total')*2)+
(getAttrByName(charid,'lvl3_slots_total')*3)+
(getAttrByName(charid,'lvl4_slots_total')*4)+
(getAttrByName(charid,'lvl5_slots_total')*5)+
(getAttrByName(charid,'lvl6_slots_total')*6)+
(getAttrByName(charid,'lvl7_slots_total')*7)+
(getAttrByName(charid,'lvl8_slots_total')*8)+
(getAttrByName(charid,'lvl9_slots_total')*9);
},
getManaUsedByCharacterID = function(charid){
return 0 +
(getAttrByName(charid,'lvl1_slots_expended')*1)+
(getAttrByName(charid,'lvl2_slots_expended')*2)+
(getAttrByName(charid,'lvl3_slots_expended')*3)+
(getAttrByName(charid,'lvl4_slots_expended')*4)+
(getAttrByName(charid,'lvl5_slots_expended')*5)+
(getAttrByName(charid,'lvl6_slots_expended')*6)+
(getAttrByName(charid,'lvl7_slots_expended')*7)+
(getAttrByName(charid,'lvl8_slots_expended')*8)+
(getAttrByName(charid,'lvl9_slots_expended')*9);
