I am trying to modify a script that tracks hp, but not being familiar enough with everything, I am lost. (a script The Aaron posted here originally) Why I am trying to modify the script? I am running Pathfinder 1e, in which a character is disabled at 0 hp, dying in negative hp, and dead at a number of negative hit points equal to the character's Constitution score. Trying to do the following specifically with the script. (using roll20 character sheet for pathfinder 1e) dead at hp = negative constitution (with dead condition) (or at 0 hp if creature has no constitution score) dying at negative hp (with dying condition) disabled at 0 hp (with disabled condition) /* global TokenMod, ChatSetAttr */
on('ready', () => {
// Configuration parameters
const HPBarNum = 3;
const TempHPMarker = 'red';
const DeadMarker = 'dead';
const TempHPAttributeName = 'hp_temp';
// new constants
const DisableMarker = 'half-heart';
const DyingMarker = 'skull';
const ConScore = 'constitution';
//end new constants

const tempHP = parseFloat(temp_hp.get('current'))||0;
const newTmpHP = Math.max((tempHP+diff),0);

TokenMod.ObserveTokenChange(accountForHPBarChange);
}
if('undefined' !== typeof ChatSetAttr && ChatSetAttr.registerObserver){
ChatSetAttr.registerObserver('change',onAttributeChange);
}
assureTempHPMarkers();
}); A second minor issue I have encountered with this script is the updating of the temp hit points with the condition on the token. Everything reports correctly on the character sheet, but the condition number (on the token) does not report correctly. Thanks for any help in advance.
