AddEditNumberArrows Stops Working on Keyed objects

[bentraje]

Hi,

I have AddEditNumberArrows element where it modifies an object at real time. The problem is it stops working on keyed objects.

You can see the problem here:
https://www.dropbox.com/s/icqinbldrr0pn67/c4d216_addeditnumberarrows_stops_working_on_keyed_object.mp4?dl=0

You can check the working code here:

import c4d
import sys
from c4d import bitmaps, documents, gui, plugins, threading, utils


class MyDialog(c4d.gui.GeDialog):

    def __init__(self):
        doc = c4d.documents.GetActiveDocument()
        self.finger_B_01_L_con = doc.SearchObject('Cylinder')

    def CreateLayout(self):
        self.AddEditNumberArrows(id=404040, flags=c4d.BFH_LEFT, initw=100, inith=0)
        return True

    def InitValues(self):
        val = self.finger_B_01_L_con[c4d.ID_BASEOBJECT_REL_ROTATION,c4d.VECTOR_Z]
        self.SetDegree(404040, val, min=-180, max=180, step=1, tristate=False)
        return True


    def Message(self, msg, result):

Hello,

The animation track "erase" the value you are setting with your code, and that's normal.

you can probably deactivate the track while you are setting those keys.

I've picked the example from our git repo and tweak it a little bit.

import c4d
#Welcome to the world of Python
def DesactivateTracks(op):
    # Retrieves the tracks.
    tracks = op.GetCTracks()
    # Track list that we want to desactivate.
    trackListToDIsable = [c4d.ID_BASEOBJECT_POSITION, c4d.ID_BASEOBJECT_ROTATION, c4d.ID_BASEOBJECT_SCALE]
    for track in tracks:
        did = track.GetDescriptionID()

        # If the Parameter ID of the current CTracks is not on the trackListToDIsable we go to the next one.
        if not did[0].id in trackListToDIsable:
            continue

        track.SetBit(c4d.BIT_ANIM_OFF)
    


def main():
    obj = op.GetObject()
    if obj is None:
        raise ValueError("couldn't find the parent object")
    # Desactivates the tracks  
    DesactivateTracks(obj)
    
    # Adds a rotation to the current one.
    rot = obj.GetRelRot() + c4d.Vector(0,.2,0)
    obj.SetRelRot(rot)

Hi @m_magalhaes

Thanks for the response.
I tried your code. It does work with the keyed object.
The problem is it overrides the previous values.
For instance, Frame 0: Value 0. Then key somethin in Frame 12: Value 20
The Frame 0 now has Value 20

You can see the problem here:
https://www.dropbox.com/s/fn7b1ti7s4f8sk9/c4d216_addeditnumberarrows_stops_working_on_keyed_object02.mp4?dl=0

I initially thought it was just Activating the track again. So I added that snippet but I still have the same problem. You can check the working code here:

[Manuel]

hello,

• opening a DLG_TYPE_ASYNC shouldn't be done in a script, you should create a CommandeDataPlugin to store your GeDialog
• your ActivateTracks isn't right, track.SetBit(c4d.BIT_ACTIVE) is not the right command to "activate" a track. In that case, activate mean "selected" Have a look at this page for more information about BITs. Because you have set the bit to BIT_ANIM_OFF you have to delete that bit using DelBit
• In your vidéo, the yellow point mean "the field value is not the same as the track value" That also mean your track is not enabled.

Your script, as you are trying to do it, will never work. Disabling the track, change the value, reactivate the track = the object will go back to the defined value of the track. So you have never the change to create a keyframe with the right value.

Get a look at those examples if you want to add keys to your tracks (or manage tracks).

there's this one in particular that could help you.

But maybe you can have a look at TranslateDescID and we have an example here

This could allow to create a tool (instead of a gedialog) where you can route your description value to another parameter of another object. So the track and keys will not be created for your tools'parameters, but on your target's parameters. (maybe it's not clear)

Cheers,
Manuel.

@m_magalhaes

Thanks for the response.
So, I guess the workflow above would be to set the keys manually.

Is there a way I can leverage the "Auto-Key" function?
I don't mind if its hack. I just want it to work and just want to animate for now.

So basically, change the value and have the auto-key handled the keying much the same way when changing value using the default UI (i.e. not using script/plugin).

[Manuel]

hello,

see this thread about using the autokey

Let me know if you have any questions.

Cheers,
Manuel

Hi @m_magalhaes

Thanks for the response.

RE: Your script, as you are trying to do it, will never work. Disabling the track, change the value, reactivate the track
Oh okay. The "reactivation part" was just my hunch since you deactivate it first. I was thinking to reactivate it again.

That said, I tried doing only Disabling Track and Change Value but the result is still the same (i.e. It does work with the keyed object. The problem is it overrides the previous values. )

RE: your ActivateTracks isn't right, track.SetBit(c4d.BIT_ACTIVE) is not the right command to "activate" a track.
So I guess this part is irrelevant since I don't need to activate/reactive it?

RE: this thread about using the autokey

I tried the autokey with the doc.AutoKey and even with the doc.Recordbut I still get the same result ( .e. It does work with the keyed object. The problem is it overrides the previous values.)

Here is the working code in a plugin form as you suggested:
It only works on the object named "Cylinder" same as before:

@bentraje said in AddEditNumberArrows Stops Working on Keyed objects:

It does work with the keyed object. The problem is it overrides the previous values.)

sorry i wasn't clear with what i said (or i can't reproduce the issue) :

In your vidéo, the yellow point mean "the field value is not the same as the track value" That also mean your track is not enabled.

In our help you will find what colors mean and full circle or not.

the value of the parameter is -2° but the point is yellow and full, that mean the track have a key at that frame but the value isn't the same as the parameter.

Your track is deactivate. But the key value is still there

Cheers,
Manuel

[bentraje]

@m_magalhaes

Thanks for the response.

Can I clear the previous queries?

1. So is it correct to DeactiveTrack, Change Value and not Activate it again?
   or Do I have to DeactiveTrack, Change Value and ActivateTrack?
2. I understand what yellow circle means which is my problem. I thought the doc.AutoKey or doc.Record will handle that, but it didn't.

Overall, I'm confused about the overall workflow.
So far what I understand is two methods:

1. Manually:
   A) Deactivate Track
   B) Change Value
   C) Key Value
   D) Activate Track
2. Automatically.
   A) Change Value
   B) Dodoc.Autokey and doc.Record

I just want the second want because it is easier. Is this possible?

[Manuel]

hello,

With the second method (automatically) you will not be able to see the change while you are dragging the value of the parameter because the track will erase what you are doing.

I've modified a bit your code (specially now creating the key is on Command and not on Message).
I also added the CoreMessage function to react to a EVMSG_TIMECHANGED

What i'm doing,
disable the track (so we can have a feedback of the changes)
update the parameter
create a key (so we still have the feedback)
enable the track(as we have created a key, the object doesn't move)
I've also create a "FindCylinder" function so you can create the cylinder after you have launch your GeDialog. And it's easier (but maybe not optimized) to check if the cylinder exist or not.
