Undo problem

Description

Hello all,

Undo... I have found a topic by nikkib, who asked this problem, and this is my problem now as well. So i copy-paste that topic:

"Hi guys,

I have created a script for a rollout synoptic, with sliders and bone selection buttons.
Unfortunately, when you click undo, the actions you have done within this rollout are not undone.

I have managed to get it in the undo stack, but this is just a label, and it still doesnt seem to want to undo the action. (for example, sliding a slider across)

Can anyone help? It would be greatly appreciated :)

Nikki"

So: how can i create sliders-spinners in a new float, which are under controlled by the Undo button to make steps back?

Thanks your replies in advance!

Best regards,
Mátyás Végh

All events in the rollouts are not recorded to the undo buffer but you can add undo context...

on btn1 pressed do
( with undo "Whatever..." on ( ... ) )

-- the next example not recommendable... 
on spn1 changed val do
( with undo "My spinner value" on ( ... ) )

Thanks a lot!
But what is the right opportunity with the spinners or sliders? I have got a lot of spinners/sliders, and how can i put these changed values (by the spinners/sliders) into the Undo history?

If the spinner is binded to the controller, there no problems with the undo record...

-- example from the help:
spinner ball_radius "Ball radius" controller:($ball.radius.controller)

...but if not, its a pain to record all changes dynamical. In this case you can bypass the issue with some "Hold" button that to store the spinner value to a variable.

If someone has any other idea I'll glad to see it ;)

It is really not an easy case... but thanks again the answer!
