I'm trying to get feed back from my tag plugin, via print or MessageDialog.  C4D is giving me zero feed back and I'm not sure if my code is even executed.

I'm using R12, any help would be appreciated.

            msg = 'Current frame is: {0}'.foramt(currentFrame)
            print(msg)
            c4d.gui.MessageDialog(msg)

return c4d.EXECUTIONRESULT_OK

Hello ReptileCoder,

doc.GetTime() return type is BaseTime.

Do that instead:

  
time = doc.GetTime();  
fps = doc.GetFps()  
frame = time.GetFrame(fps);  
  
msg = 'Current Frame is:' +str(time2)  
print(msg)

@ReptileCoder: Calling the GUI from a tag thread is not allowed and can lead to crashs. The GUI should only be called from the main thread. There are some minor functions which allow this and they are documentated.

Thanks Nt2005.  I was able to run the frame code in a Python script and get it working, I appreciate your help.

s_rath, thank you for the info on the dangers of calling the GUI from a tag.  What I would like to do, is get debug feed back from the tag code.  And currently it appears that the Execute() method of my tag is not getting called.  So I am unsure how tag code works, and the Python documentation is a little light.

Btw, you should add the TAG_EXPRESSION flag in RegisterTagPlugin.

info=c4d.TAG_VISIBLE|c4d.TAG_EXPRESSION

Adding  |c4d.TAG_ EXPRESSION to the RegisterTagPlugin method did it.  Now my print statements are working.
Thank you s_rath!

solution:
import c4d
from c4d import plugins

PLUGIN_ID = 1234567890

class AnimationCacheTag(plugins.TagData) :

def Execute(self, tag, doc, op, bt, priority, flags) :
        '''Run the tag code'''

fps = doc.GetFps()
        currentFrame = doc.GetTime().GetFrame(fps)
        msg = 'Current frame is: {0}'.format(currentFrame)
        print(msg)

return c4d.EXECUTIONRESULT_OK

if __name__ == "__main__":
    plugins.RegisterTagPlugin(id=PLUGIN_ID, str="Animation Cache Tag", g=AnimationCacheTag,
                                    description="IDD_CACHEDIALOG", icon=None,
                                    info=c4d.TAG_VISIBLE |c4d.TAG_EXPRESSION )
