That's the content of the "content" field in the data

oblique stream Nov 9, 2022, 4:50 PM

#

at this point, its too late

#

as the html has been generated for the roll

cerulean siren Nov 9, 2022, 4:50 PM

#

Damn - this is in preCreate too

oblique stream Nov 9, 2022, 4:51 PM

#

you need to find a place before this html is generated OR come in after the chat message has been created, extract any roll data it has in its flags, create a new roll from that data, modify the roll, evaluate the roll, and store it back in the chatmessage's flags

cerulean siren Nov 9, 2022, 4:52 PM

#

With CONFIG.debug.hooks I don't see any other hooks being called when I roll the "item" unfortunately

#

I don't see any roll data in the flags of either preCreate or CreateChatMessage - the only roll data is in that HTML

#

oblique stream Nov 9, 2022, 4:55 PM

#

indeed, so you might have to parse the HTML directly after the chat message is rendered

#

which requires a world script to keep it in sync for all clients

cerulean siren Nov 9, 2022, 4:56 PM

#

Yeah I have that part as a world script already and can do it on render of the chat card - but how would I update that card?

#

let searchString = `<div class="dice-formula">2d6 + 1 + 0</div>`;

let replaceString = `<div class="dice-formula">2d6 + 1 + ${mastery}</div>;`;```

#

IE: here was what I was thinking - I just don't know how to "apply" this so that the chat card is updated

oblique stream Nov 9, 2022, 4:57 PM

#

you update the chat message's "content" field with the new HTML string

cerulean siren Nov 9, 2022, 4:58 PM

#

So if I do this ```content = content.replace(searchString, replaceString);


How would I apply that to the chat card?

cerulean siren Nov 9, 2022, 5:10 PM

#

oblique stream you update the chat message's "content" field with the new HTML string

I tried this but no luck

let chatMessage = game.messages.get(data._id);

chatMessage.updateSource({ content: content });```

#

I can see my content has the right content, but the chat card isn't updating in chat

oblique stream Nov 9, 2022, 5:13 PM

#

a normal update

#

updateSource just modifies the local data and does not trigger update hooks

cerulean siren Nov 9, 2022, 5:16 PM

#

oblique stream updateSource just modifies the local data and does not trigger update hooks

Ok this works now 😄

BUT: It seems to be stuck in an infinite loop of just updating it constantly

oblique stream Nov 9, 2022, 5:17 PM

#

what hook are you using?

cerulean siren Nov 9, 2022, 5:17 PM

#

renderChatMessage

#

 
 let actorId = data.speaker.actor;
 let actor = game.actors.get(actorId);
 let content = data.content;
 let rolltype;
if (content.includes("Strength")) rolltype='str';
if (content.includes("Agility")) rolltype="agi";
if (content.includes("Influence")) rolltype="inf";
if (content.includes("Wits")) rolltype="wit";
if (content.includes("Arcane")) rolltype="arc";
if (content.includes("Luck")) rolltype="luk";

let actorStat = actor.system.stats[rolltype];
let mastery = actor.system.attrTop.hold.value;
let searchString = `<div class="dice-formula">2d6 + 1 + 0</div>`;
let replaceString = `<div class="dice-formula">2d6 + 1 + ${mastery}</div>;`;
content = content.replace(searchString, replaceString);
let searchString2 = `</em></div>`;
let replaceString2 = ` Mastery (+${mastery})</em></div>`;
content = content.replace(searchString2, replaceString2);
rolltotal = content.substr(content.indexOf('"dice-total">')+1, 1);

let searchString3 = `<h4 class="dice-total">4</h4>`;
let replaceString3 = `<div class="dice-formula">2d6 + 1 + ${mastery}</div>;`;


let chatMessage = game.messages.get(data._id);

chatMessage.update({ content: content });
//if (actorStat.toggle)
//{
    
//}

});```

#

you may need to add some info to the optional argument of update so your hook can look at it and say "wait, this is my update, dont do anything"

cerulean siren Nov 9, 2022, 5:18 PM

Hmm - do you have an example of this?

#

I was hoping isroll would be enabled for the original roll but its not

oblique stream Nov 9, 2022, 5:22 PM

#

here (https://github.com/trioderegion/squadron/blob/bffe26e9050980c6d2aff2af49fe99633a77f970/scripts/modules/logistics.js#L250) is where I issue an update and add an options flag (squadron.lookout.leadersflag) to the update.

and here (https://github.com/trioderegion/squadron/blob/bffe26e9050980c6d2aff2af49fe99633a77f970/scripts/modules/lookout.js#L153) is where my hook looks for that flag and stops processing

cerulean siren Nov 9, 2022, 5:28 PM

#

Is adding the flags to the chat message the same?

#

I did this chatMessage.update({ content: content, ishookupdated: true }); but ishookupdated doesn't exist when I go look for it

oblique stream Nov 9, 2022, 5:28 PM

#

not flagging the chatmessage, adding information to the update process so we know its "us" doing it

cerulean siren Nov 9, 2022, 5:29 PM

#

Yeah that's what I tried to do with the ishookupdated - is that not the right way?

oblique stream Nov 9, 2022, 5:30 PM

#

no, because that would cause another render hook and that is causing the infinite loop

cerulean siren Nov 9, 2022, 5:31 PM

#

I'm confused haha

At the top of my hook I was going to check if the chat message had ishookupdated and if it did then not to run the code

cerulean siren Nov 9, 2022, 5:34 PM

oblique stream no, because that would cause another render hook and that is causing the infinit...

Should it be outside the 'content' part?

chatMessage.update({ content: content}, ishookflag: true);```

oblique stream Nov 9, 2022, 5:34 PM

#

yes, but as an object (your snippet is invalid syntax)

cerulean siren Nov 9, 2022, 5:36 PM

#

oblique stream yes, but as an object (your snippet is invalid syntax)

message.update({},{ishookflag: true});

#

Is that correct?

oblique stream Nov 9, 2022, 5:36 PM

#

nods, yea

cerulean siren Nov 9, 2022, 5:37 PM

#

oblique stream *nods*, yea

I don't see the ishookflag when I do a get message - am I missing something?

oblique stream Nov 9, 2022, 5:38 PM

#

it will be present in the preUpdateChatMessage and updateChatMessage hooks

cerulean siren Nov 9, 2022, 5:39 PM

#

oblique stream it will be present in the preUpdateChatMessage and updateChatMessage hooks

Oh - how would I link the two hooks? If I check it in preUpdateChatMessage and it exists then I want to run the code under the renderchatmessage hook but otherwise I wouldn't

oblique stream Nov 9, 2022, 5:41 PM

#

create the renderChatMessage hook as a Hooks.once when your preUpdateChatMessage hook detects (or doesnt detect) your options flag

cerulean siren Nov 9, 2022, 5:44 PM

#

oblique stream create the renderChatMessage hook as a `Hooks.once` when your preUpdateChatMessa...

In this case preUpdateChatMessage hook wouldn't fire until I do the update - so do I need to do a hook once first in the world script, and then do the hook.once within the PreUpdate for any subsequent ones?

oblique stream Nov 9, 2022, 5:44 PM

#

im not 100% sure without digging into the code flow myself, but you definitely have the right idea

#

either a hook needs to fire, or needs to not fire, based on data received during preUpdate

cerulean siren Nov 9, 2022, 6:05 PM

oblique stream im not 100% sure without digging into the code flow myself, but you definitely h...

Thanks - trying to figure out the initial trigger - Im trying to add a flag to the messages flags field but its not working

One for the initial run, and the second flag for the preUpdate

chatMessage.update({ content: content, flags: {ishookflag: true}},{ishookflag: true});

#

content appears to update, but flags doesn't show the flag I'm trying to add

oblique stream Nov 9, 2022, 6:05 PM

#

my use of "options flag" may have been misleading

#

i dont think you need to actually set a flag on the chatmessage document

#

just that second options object with "ishookflag" should propogate throughout all chat message updating hooks

cerulean siren Nov 9, 2022, 6:07 PM

#

It does but I don't know how to trigger the original update (since the update hooks won't be triggered)

#

IE: How do I trigger my function to update the chat message when the update chat message hook won't be called yet

#

If I put it under RenderChatMessage I can't grab that option so I don't know if it's been done

oblique stream Nov 9, 2022, 6:08 PM

#

you will be using preCreate to detect if you need to operate on this chat message, i think

cerulean siren Nov 9, 2022, 6:10 PM

#

preCreateChatMessage? It will have that option?

oblique stream Nov 9, 2022, 6:12 PM

#

that's where you would likely set the option -- you add any info to the creation options that your later hooks need to make their decisions. Something that says "Hey, this is a roll message that needs or may need to be modified".

#

then, when the later hooks "take action" and update the chat message, they will add an option to the update that says "hey, this message has been handled, dont take any further action" to any of your hooks

cerulean siren Nov 9, 2022, 6:17 PM

#

oblique stream you will be using preCreate to detect if you need to operate on this chat messag...

Ok that makes sense - how do I add that option in preCreateChatMessage?

chatMessage.update({},{ishookflag: true}); }

says .update isn't valid

oblique stream Nov 9, 2022, 6:18 PM

#

in the hook, you receive several arguments, the...second, or third (i forget) is the current options argument

#

simply say options.ishookflag = true

#

once you know its a message you want to handle

cerulean siren Nov 9, 2022, 6:18 PM

#

Oh ok!

cerulean siren Nov 9, 2022, 7:26 PM

#

oblique stream once you know its a message you want to handle

This is what I ended up with

    updateChatMessage(data, options, flags);

});


}```

#

📎 message.txt

#

#

Result (Mastery part is added)

cerulean siren Nov 9, 2022, 7:28 PM

#

oblique stream simply say `options.ishookflag = true`

Thanks very much for your help - I couldn't have figured it out without it

oblique stream Nov 9, 2022, 7:29 PM
