Ive made a plugin that moves and rotates objects that are in the scene. I can move and rotate them by using handles that I have created.
The problem is that autokeyframing doesn't work. To move and rotate them I am modifying the objects matrix.
I thought a simple

    
    
    
    
    op->Message(MSG_CHANGE);
    
    
    

would be enough for cinema to recognize that the objects matrix has changed but it doesn't.

Sorry, I just got confirmation from the programmers that it's not possible to trigger auto keyframing from a plugin.

Howdy,

Reviving this old thread to ask:
Is this possible now with the R9 SDK and up, using the BaseDocument::AutoKey() function?

And if so, can you show an example of how to use it? ;o)

Adios,
Cactus Dan

Hi,

Reviving this thread again; can the autokey function be used now with R10/10.5?

We cannot get it going here, although its in the SDK.

We cannot find an answer to this, did you find out anything Dan?

Howdy,

Yes, the AutoKey() function works, but you also need two functions: IsCommandEnabled()
IsCommandChecked()

... from c4d_general.h to make it work. The IsCommandChecked() function is only available from R9.6 and up, so I couldn't get it to work in anything below R9.6. :o(

You also need the ID's of the auto key commands which are:

\>       IDM_A_SIZE               = 12418,

\>         
\>       IDM_AUTOKEYS          = 12425,  
\>  };  
\>  

`

Then use the functions like this:

\>  {  
\>       undoOp = (BaseObject* )op->GetClone(COPY_NO_HIERARCHY,NULL);  
\>  }

\>                      IsCommandChecked(IDM_A_DIR),  
\>                      IsCommandChecked(IDM_A_PARAMETER),  
\>                      IsCommandChecked(IDM_A_PLA));  
\>  }

`

That should do it. ;o)

Thanks Dan. I'm doing exactly that, except:

the bools, wich are all set to true by me, because i want to record everything.

I don't change anything, myself because I need to record a XPresso driven object.

I record every frame, so the clone is taken and stored and used in the next frame to be compared with the current frame. That should be possible?

My clone seems to be OK;

Howdy,

OK, I see.

Yeah, I would think it should be possible to keep a pointer to the cloned object and update it after the Xpresso's execution for each frame so it will always be the previous state of the object for each next frame. ;o)

Adios,
Cactus Dan
