Hey,

i know how the Undo function in the SDK works, but i have a problem with it 😄

How can i undo a variable?

As a example i have a counter and every time i click the counter get + 1.
How can i redo the counter?

The problem with pseudo code:

counter = 0
onClick(){
c4d.StartUndo()
counter = counter + 1
c4d.AddUndo(counter) # how i want it 😉
c4d.EndUndo()
}

That's not possible. You have to save the state in an object or the document or know how you
can re-calculate the state based on other data.
