TIL you can set the flags key on a document to whatever you want to (e.g. a string). This is a sure fire way to completely ruin someone else's day, or your own day when another module un-does this by setting a flag 'correctly'.

game.actors.getName('A Character').update({
  ['flags']: 'A value'
})

game.actors.getName('A Character').data.flags // 'A value'

game.actors.getName('A Character').setFlag('world', 'someKey', 'some string value')

game.actors.getName('A Character').data.flags // { world: { someKey: 'some string value' }}

game.actors.getName('A Character').update({
  ['flags']: 'A value'
})

game.actors.getName('A Character').data.flags // 'A value'

game.actors.getName('A Character').setFlag('world', 'someKey', 'some string value')

game.actors.getName('A Character').data.flags // { world: { someKey: 'some string value' }}

dnd5e for instance gets big mad when its flags disappear from an actor.

Is this a "bug"?

Calego•941d ago

I would not categorize it as such. If I got sent a bug with this at work, my reply to it would be "... don't" and I'd WONTFIX it.

Daniel Thorp•941d ago

Makes sense, thanks

Calego•941d ago

if I couldn't get away with telling them to "just don't" I'd say something like:

The amount of complexity and performance overhead that would be introduced by adding validations to this low-level API do not outweight being able to prevent the edge case described by this issue.
