hook preCreateToken update token name

I'm trying to update the token name when dropping a token on a scene. I basically have something like this

Hooks.on("preCreateToken", async function (tokenDocument) {
  tokenDocument.actor.update({name: "some dude"});
});

Hooks.on("preCreateToken", async function (tokenDocument) {
  tokenDocument.actor.update({name: "some dude"});
});

I'm trying to follow the operation described here https://foundryvtt.com/article/v11-actor-delta/ but getting an error related to id and embeddedCollection how should I update a token in the preCreateToken hook

Solution:

so switching the hook to createToken and keeping everything else the same seems to get the functionality i'm looking for.

Are you updating the token name, or the actor name?

I'm trying to update the token name. i've also tried

Hooks.on("preCreateToken", async function (tokenDocument) {
  tokenDocument.update({name: "some dude"});
});

Hooks.on("preCreateToken", async function (tokenDocument) {
  tokenDocument.update({name: "some dude"});
});

and every variation in between i can think of 😅 I essentially want this but within the preCreateToken hook where canvas.tokens.controlled[0] is the token being created

canvas.tokens.controlled[0].document.update({name: "bla"})

canvas.tokens.controlled[0].document.update({name: "bla"})

OK, so (1) You cant use an async function inside a "pre" hook like this. (2) You can't use update to change a document before it has been created; you use updateSource instead.

Hooks.on("preCreateToken", function(tokenDocument) {
  tokenDocument.updateSource({name: "some dude"});
});

Hooks.on("preCreateToken", function(tokenDocument) {
  tokenDocument.updateSource({name: "some dude"});
});

thanks. though I just tried this to the same result 😕 I don't get any errors but the token name remains the same as the actor or prototype token

Did you make sure the script actually runs?

here it is on the line with a breakpoint i can step in and through the update.

bluegreymouse•45d ago

but the token still ends up on the canvas without that name

I still spy some await in there, so your hook callback is still async, right? Foundry does not await hooks, so your callback has to be synchronous. Giving an async callback results in your function not running before the token creation data is sent to the server.

ah okay i see. I'm trying to roll on a rolltable for a random name to apply to a token. is that not something I can do in a hook since it can't contain async calls?
