[Help] Send Current HP after HP Change to Chat (GM Whisper)

1611505553
Hi, I'm looking looking for a script that, whenever a token's HP (bar 1) change, sends the new value to chat via a GM Whisper. For any token, and I guess it should refer to the token's name. Why? So that when mistakes happen, even after a couple of rounds, it's easier to construct what happened and figure out where things should be now. I want it to show up in the Chat Log so that even if it scrolls up off the top of the current chat window, it can be viewed with "View all chat entries for this game". I think this is probably fairly simple to do; wondering if anyone has a script that does this already? Thanks.

Give this a try: /* global TokenMod ChatSetAttr */ on('ready',()=>{ const bar = 'bar1'; const upColor = '#0d0'; const downColor = '#f66'; const getActivePages = () => [...new Set([ Campaign().get('playerpageid'), ...Object.values(Campaign().get('playerspecificpages')), ...findObjs({ type: 'player', online: true }) .filter((p)=>playerIsGM(p.id)) .map((p)=>p.get('lastpage')) ]) ]; const sign = (n) => (n>0 ? '+' : (n<0 ? '-' : ' ')); const colored = (c,p,s) => ((c>p) ? `<span style="color:${upColor}">${s?sign(c):''}${c}</span>` : ((c<p) ? `<span style="color:${downColor}">${c}</span>` : c )); const handleTokenChange = (obj,prev)=>{ let pages = getActivePages(); if(pages.includes(prev._pageid) ){ let hp = obj.get(`${bar}_value`); let hpMax = obj.get(`${bar}_max`); let pHp = prev[`${bar}_value`]; let pHpMax = prev[`${bar}_max`]; let hpDiff = (hp-pHp); let hpMaxDiff = (hpMax-pHpMax); if(hp !== pHp || hpMax !== pHpMax){ sendChat('',`/w gm <div style="padding: 2px .5em; font-size: .8em;background: #333;color:#ccc;border-radius:.5em;"><code>${prev.name}</code> ${pHp}/${pHpMax} => ${colored(hp,pHp)}/${colored(hpMax,pHpMax)} (${colored(hpDiff,0,true)}/${colored(hpMaxDiff,0,true)})</div>`); } } }; on('change:graphic', handleTokenChange); if('undefined' !== typeof TokenMod && TokenMod.ObserveTokenChange){ TokenMod.ObserveTokenChange(handleTokenChange); } if('undefined' !== typeof ChatSetAttr && ChatSetAttr.registerObserver){ ChatSetAttr.registerObserver('change',handleTokenChange); } }); Here's what it looks like: Also supports TokenMod and ChatSetAttr changes.

Seems to work well enough; thanks!  It only has an oddity where if there are multiple maps that have a token with the same name, it sends a chat message for every instance of that token name. I tend to leave multiple PC tokens on multiple maps as players are wandering around the dungeon--especially a large one like The Dead in Thay--saves me the trouble of switching tokens around every time they move to a new map. I just have to move them. It's nothing I can't live with though.  Thanks The Aaron!

Easily handled, adjusted the script above to only issue notices for tokens on active pages.  You'll still get multiple notices if you have split the party and have the same character on multiple pages, or if you have multiple copies of the same token on the same page.  I could actually fix that, if that's an issue.
Thanks for this scriplet! I've started using it in my own game, and added a button for undoing the most recent change using TokenMod. Changed this line sendChat('',`/w gm <div style="padding: 2px .5em; font-size: .8em;background: #333;color:#ccc;border-radius:.5em;"><code>${prev.name}</code> ${pHp}/${pHpMax} => ${colored(hp,pHp)}/${colored(hpMax,pHpMax)} (${colored(hpDiff,0,true)}/${colored(hpMaxDiff,0,true)})</div>`); to this sendChat('',`/w gm <div style="padding: 2px .5em; font-size: .8em;background: #333;color:#ccc;border-radius:.5em;"><code>${prev.name}</code> ${pHp}/${pHpMax} => ${colored(hp,pHp)}/${colored(hpMax,pHpMax)} (${colored(hpDiff,0,true)}/${colored(hpMaxDiff,0,true)}) [<code>UNDO CHANGE</code>](`!token-mod --ids ${prev._id} --ignore-selected --set bar1_value|-[[${hpDiff}]])</div>`);
