Delete and update add_note don't work

[mr_Creator]

Hello,
I create note:

@note = Sketchup.active_model.add_note 'Note', 0.8, 0.9

But I cannot delete and change the note. Help please, I used different methods, but none helped.

@note = Sketchup.active_model.add_note 'Note', 0.8, 0.9

You may realised that is creating Sketchup::Text https://ruby.sketchup.com/Sketchup/Text.html
To change:

@note.set_text "This is another note"

Most probably to see changes, the view need to redraw.

Sketchup.active_model.active_view.invalidate

do delete:

@note.erase!

When i use:

@note.set_text "This is another note"
Sketchup.active_model.active_view.invalidate

then I get this (check image)

the text is superimposed on each other. Sketchup 2020

You didn't say what you didbefore.
I guess you actually did something like this:

@note = Sketchup.active_model.add_note 'Note', 0.8, 0.9
@note = Sketchup.active_model.add_note 'Note', 0.8, 0.9
@note.set_text "This is another note"
Sketchup.active_model.active_view.invalidate

If you can tell me what your goal is at all, I might be better able to suggest something...

The bare bones code is:

note=Sketchup.active_model.add_note("The initial note", 0.8, 0.9)
### where 'note' is a reference to that newly made text-entity
Sketchup.active_model.active_view.invalidate
### refreshes the view

later on you can use

note.text="This is the changed note"
Sketchup.active_model.active_view.invalidate

The @note would only apply if you are reusing variables between methods etc.
Also the set_text(...) method operates outside of the undo-stack, whereas the text= works within it.
Also, please parenthesize your arguments...
To erase the note use note.erase!

Just tested Sketchup::Text#set_text on SU2020 and it (as Dezmo says) does not display the change until the view is redrawn. So Sketchup.active_model.active_view.invalidate is necessary to see the change.

I'll open a documentation issue for this "quirk".
