The problem here is that Message() is called before Main() (nothing you can changed)

Hello.
Thank you so much. I've understood. Yea, it works. I'd break my mind to understand it by myself. So, then I gonna optimize drawcalls (don't know how to call it another) of LaunchUpdate() func

hello,
Is it possible to have the last version of your file so i have a chance to follow you and try to help you.

Sure. Thanks in advance. I also commented on my code to better to understand.
Experieces_old.c4d

I get the same issue. The script gives only previous data (randint limit). I know why, but I don't know how to get an active data.

def message(id, data):
    if id == c4d.MSG_DESCRIPTION_COMMAND:
        randomButtons = [5] #Random  buttons Ids
        buttonID = data['id']
        SubList = [] #container storing id's values to have to changing
        SubList = randomId_new(SubList,[3,4])#filling the container
        if buttonID[0].id == c4d.ID_USERDATA:#check for user data
            for RandomButtonId in range (0,len(randomButtons)):#loop for each button
                if buttonID[1].id == randomButtons[RandomButtonId]:#check button ID
                    for SublistId in range (0,len(SubList[RandomButtonId])):
                        RandomLimit = 0 #limit for randint
                        for id, bc in op.GetUserDataContainer():
                            if (id == c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER,0), c4d.DescLevel(SubList[RandomButtonId][SublistId]))): #check id
                                cycleBC = bc.GetContainer(c4d.DESC_CYCLE)
                                for element in cycleBC: #define len of cycleList
                                    RandomLimit += 1
                        op[c4d.ID_USERDATA,SubList[RandomButtonId][SublistId]] = randint(0,RandomLimit - 1) #generate random value
                        print(str(SubList[RandomButtonId][SublistId]) + ': ' + str(RandomLimit)) #checking to console

What do you mean with "hierarhy disturbing"? What do you mean with "generate active object after generating random"?

"Hierarhy disturbing".
Simply put, there is first func (where there are object details) and there is the second func which generate a random number, but data of active object stores in the first func. Need to execute the second func before first to make it works. But it doesn't right cause' it disturbs actions timeline. Right way is: First display object to the viewport, then generate random nimber after pressing button. But this code requires to run second func before first one.
"generate active object after generating random"
I think attached video link better speaks for me.

Why is your user interface on the "Interface" null object and not the Python Tag itself?

Thanks. Need to try.

Hello everyone.
There are a few classes.
One for choosing an object in the CycleList.
Two for choosing a random object via change c4d.userdata value
One works fine. But when I choose a random object I need to click on the viewport to update showing object. How to update viewport without clicking?

I also have tried on the random class:

 c4d.EventAdd()
            c4d.CallCommand(12147, 12147)
            c4d.DrawViews( c4d.DA_ONLY_ACTIVE_VIEW|c4d.DA_NO_THREAD|c4d.DA_NO_REDUCTION|c4d.DA_STATICBREAK )

It doesn't work.
Object class:

 if (config['hideState'] == True): #hide selected object
            for indexObjectHide in range (0, limit): #loop for geting all objects
                if (indexObjectHide == self.userdataGroup[c4d.ID_USERDATA,userDataId]): #which object is selected
                    self.parentObject.GetChildren()[indexObjectHide].SetEditorMode(2)
                    self.parentObject.GetChildren()[indexObjectHide].SetRenderMode(2)
                else:
                    self.parentObject.GetChildren()[indexObjectHide].SetEditorMode(1)
                    self.parentObject.GetChildren()[indexObjectHide].SetRenderMode(1)

Random class:

if (self.userdataGroup[c4d.ID_USERDATA,userDataId] == True): #If random button clicked
            SubLists = [] #
            for ListIndex in range (0,len(config['Random id'])):#config['Random id'] is var where I can point userdata ids ehich will be randomed
                SubLists.append([config['Random id'][ListIndex]])
            indexList = []
            for indexEl in range (0,len(SubLists)): #Loop for each id
                for id, bc in self.userdataGroup.GetUserDataContainer():
                    cycleBC = bc.GetContainer(c4d.DESC_CYCLE)
                    if (id == c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER,0), c4d.DescLevel(SubLists[indexEl][0]))):
                        for element in cycleBC: # get userdata data
                            if (len(indexList) == indexEl):
                                indexList.append([element[0]])
                            else:
                                indexList[indexEl].append(element[0])
                self.userdataGroup[c4d.ID_USERDATA,SubLists[indexEl][0]] = randint(0,len(indexList[indexEl]) - 1) #Change userdata values
            self.userdataGroup[c4d.ID_USERDATA,userDataId] = False

Seems I've understood why I get the issue. I put random class before object class and it works 'cause in this code, I get an active object before getting random value. But it is doesn't correct in point of view of the code. It's hierarhy disturbing. Ways to generate active object after generating random?
