Need a Round Counter API script but dont know what to use

Hello everyone, I am in need of adding a round counter on my turn tracker, I have read the forums but some of them are outdated or not support it anymore. I wonder if you guys know one that works atm, I am not looking for something fancy but just will add the round I am and will show which round we are on game.
Thx foor all help

I believe Aaron's TurnMarker script is still viable

Yup.  It's got more than you probably need, but would work.

You could also use this AddCustomTurn Snippet:

on('ready',() => {

    const checkFormulaOnTurn = () => {
        let to=JSON.parse(Campaign().get('turnorder')||'[]');
        if(to.length && to[0].id==='-1'){
            sendChat('',`[[${to[0].pr}+(${to[0].formula||0})]]`,(r)=>{
                to[0].pr=r[0].inlinerolls[0].results.total;
                Campaign().set('turnorder',JSON.stringify(to));
            });
        }
    };

    on('chat:message',(msg) => {

        if('api' === msg.type) {
            if(msg.content.match(/^!act\b/) ){
                let who=(getObj('player',msg.playerid)||{get:()=>'API'}).get('_displayname');

                if(_.has(msg,'inlinerolls')){
                    msg.content = _.chain(msg.inlinerolls)
                        .reduce((m,v,k) => {
                            let ti=_.reduce(v.results.rolls,(m2,v2) => {
                                if(_.has(v2,'table')){
                                    m2.push(_.reduce(v2.results,(m3,v3) => {
                                        m3.push(v3.tableItem.name);
                                        return m3;
                                    },[]).join(', '));
                                }
                                return m2;
                            },[]).join(', ');
                            m['$[['+k+']]']= (ti.length && ti) || v.results.total || 0;
                            return m;
                        },{})
                        .reduce((m,v,k) => {
                            return m.replace(k,v);
                        },msg.content)
                        .value();
                }

                let args = msg.content
                    .replace(/<br\/>\n/g, ' ')
                    .replace(/(\{\{(.*?)\}\})/g," $2 ")
                    .split(/\s+--/);

                let cmds=args.shift().split(/\s+/);
                let change=parseFloat(cmds[1]);
                change = Number.isNaN(change) ? '+1' : change;
                change = `${/^[+-]\d/.test(change)?'':'+'}${change}`;
                let initial = parseFloat(cmds[2])||0;
                let entry = args.join(' ');

                if(entry.length){
                    let to=JSON.parse(Campaign().get('turnorder')||'[]');
                    to.unshift({
                        id: "-1",
                        pr: initial,
                        custom: entry,
                        formula: change
                    });
                    Campaign().set('turnorder',JSON.stringify(to));
                    if(!playerIsGM(msg.playerid)){
                        sendChat('ACT',`/w gm <div style="padding:1px 3px;border: 1px solid #8B4513;background: #eeffee; color: #8B4513; font-size: 80%;"><div style="background-color: #ffeeee;"><b>${who}</b> added entry for <b>${entry}</b> starting at <b>${initial}</b> and changing by <b>${change}</b>.</div></div>`);
                    }
                } else {
                    sendChat('ACT',`/w "${who}" <div style="padding:1px 3px;border: 1px solid #8B4513;background: #eeffee; color: #8B4513; font-size: 80%;"><div style="background-color: #ffeeee;">Use <b><pre>!act [formula] [starting value] --[description]</pre></b></div></div>`);
                }
            } else if(msg.content.match(/^!eot/i)){
                _.defer(checkFormulaOnTurn);
            }
        }
    });
});

This will add a Custom Turn named "Round" with a value that will increase whenever it gets a turn:

!act --Round

You'll have to skip past it, but other than that, should be very serviceable.

This snippet is designed for adding counters to the Turn Order.  We commonly use it for spells like:

!act -1 10 --Marcus: Bless

You can run:

!act

to get a terse help output.

thanks :)

Aaron, in the Bless snippet above, what does the -1 10 do?

!act -1 10 --Marcus: Bless

the -1 sets the formula to apply each time the custom turn comes up, the 10 sets the starting value.  So that will count down as it gets a turn.

So if it was -3, it would drop by 3 each turn?

and if it was 2, it would increase by one?

Does it accept inline rolls?

If it was 2, it would increase by 2 each turn. And yeah, it supports inline rolls. =D
