Get active object after random value



  • 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
    

    You can see full code in the attached c4d file. Pls help me

    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?



  • Hello and welcome,

    please use the Q&A system to mark your post as a question.

    Also, please use tags to inform us about which version of Cinema you are using.

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

    Why is your user interface on the "Interface" null object and not the Python Tag itself? If your UI would be on the Python Tag, you could implement the tag's message() function to handle such user events properly.

    def message(id, data):
        if id == c4d.MSG_DESCRIPTION_COMMAND:
            buttonID = data['id']
            # check for user data
            if buttonID[0].id == c4d.ID_USERDATA:
                # ceck button ID
                if buttonID[1].id == 1:
                    print("button pressed")
    

    best wishes,
    Sebastian

    And...Done.

    "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.

    Thanks. Need to try.



  • 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

  • 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.

  • hello,

    You create your UI dynamically but still use it to retrieves data. You should simply separate both.

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

    In the Message() function you can check the id == MSG_DESCRIPTION_POSTSETPARAMETER, you can retrieves the descid in the data attached.

    By checking the descid you can update only if the cycles are changed. (not the button)

    Your Main() can be "empty". I picked everything that was in Main() and copy/paste in LaunchUpdate()
    You should split that function in several parts.

    In the random function I can now call LaunchUpdate() to update the UI and use it to retrieves the data. (but as I said you should separate both)

    This now works but LaunchUpdate() is executed too much times. It would need more work to split that function in several parts.

    This look more like a design issue than a Cinema4D issue.

    Let me know if i'm not clear.

  • @m_magalhaes said in Get active object after random value:

    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
