how to set display entity scale

[DOKA1203]

i tried all of this things

 watcher.setObject(
    WrappedDataWatcher.WrappedDataWatcherObject(11, WrappedDataWatcher.Registry.getVectorSerializer()),
    Vector3F(x,y,z)
)
watcher.setObject(
    WrappedDataWatcher.WrappedDataWatcherObject(10, WrappedDataWatcher.Registry.getVectorSerializer()),
    Vector3F(x,y,z)
)
watcher.setObject(
    WrappedDataWatcher.WrappedDataWatcherObject(19, WrappedDataWatcher.Registry.get(java.lang.Float::class.java)),
    2f
)
watcher.setObject(
    WrappedDataWatcher.WrappedDataWatcherObject(20, WrappedDataWatcher.Registry.get(java.lang.Float::class.java)),
    2f
)
watcher.setObject(10, Vector3F(x,y,z))
watcher.setObject(11, Vector3F(x,y,z))
watcher.setObject(19, 2f)
watcher.setObject(20, 2f)

but its not working

so as far as setting the scale goes, the first one should be right. can you provide the rest of the code? what happens in game?

Do you get any exceptions in the log? And what exactly are you trying to archieve?

[DOKA1203]

it has no exception log but it not works for me. i want to make a block display which one player can see

[lukalt]

And what is the observed behavior? Is the display completely invisible or just the wrong size?

[DOKA1203]

just wrong size,

[lukalt]

You probably also need to set Width (19) and Height (20). Its 0 by default
