This is how to use a multi-button with C++ so that it performs an action when the user changes the button to the second option:

if (tag->GetData().GetLong(MULTIBUTTON) == TWO) // if the multi-button is set to this mode  
  {  
      GePrint("Option Two Selected");   
  }

Here is an example plugin with a multi-button on it as an example:https://sites.google.com/site/scottayersmedia/MyPythonTag.zip?attredirects=0&d=1

How do I write this same code in python so when I change the selection. It performs an action like my C++ code?

First, if you want to fo this, you must *not* return if no "id" is given, because the id is only available if a button is pressed. Just leave the line with "if not id: return" out.

To check if Option 2 is enabled:

        if op[c4d.MULTIBUTTON] == c4d.MULTI_TWO:  
          print "Option Two is enabled"

Did you try to use that on my example?
That doesn't seem to work for me.
Neither does using the numeric id's and the tag as the owner:

    
    
    if tag[1008] == 1010:  
     print "Option Two is enabled"

Yes, it worked for me.

Did you delete

if not id: return

?

PS: in your example, the tag is "op" and not "tag" ^^

/edit:
mom, I'll upload the corrected Message method

/edit:
Here it is.

def Message(self, op, type, data) :  
  doc = op.GetDocument()  
  id = GetMessageID(data) # calls to the custom GetMessage() method  
  # #### if not id: return True  # Error handling  
    
  if id == c4d.CLICK_ONE:  # If this Gizmo is activated  
  #Do Something  
  print "Button1 was Clicked"  
    
  if id == c4d.CLICK_TWO:  # If this Gizmo is activated  
  #Do Something  
  print "Button2 was Clicked"      
  
  if op[c4d.MULTIBUTTON] == c4d.MULTI_TWO:  
  print "Option 2 is selected."  
    
  return True

Weird.
It doesn't work for me.

Not only that. I cannot use the long id names without getting definition errors.
I have to use the numerical ones to get it to run.

We both have the same code so I can't imagine why we're getting such different results.
I must be doing something really stupid.

I've got a book on Windows OS programming that I keep meaning to read. But haven't had the time.
Maybe I can write my own launcher program that kills that file first..Then opens the c4d .exe file.
It seems like something that shouldn't be that hard to do.

I figured out how to create a .bat file that will do two things

1- Delete the coffeesysmbolschache file
2- Launch Cinema4D

This batch file can be used to launch C4D without worrying about that pesky cache file.
No more cache file headaches.

I'm willing to share how to do this. But this is potentially DANGEROUS!!!!
Deleted files with a .bat file DO NOT COME BACK!!! So be VERY careful with this!!!

Create this code in a plain text file with no formatting:

@echo off  
  
del "The path to your coffeesymbolscache file goes here" /Q/S >nul  
  
start "\" "The path to your cinema 4d.exe file goes here" "\"

When you're done setting your paths. Save the file as "whatever name you like.bat"
When you double click on it. It will delete the cache file and launch Cinema 4D.

Please be careful with this one.
Make sure your paths are right when using the del option.

You never said that it runs automatically at start up.
That's good to know.

I thought you will recognize it. ^^
If you think a bit about it, you will notice that a .pyp file *must* be executed at startup. Or when do you want your plugin to be registered if not at startup ? :)

I was hoping that this might possibly be a way to change some of the C4D interface options when C4D starts up.

I just started looking into this:

from  os  import remove  
import os  
import time  
import c4d  
from c4d import gui, utils  
  
start = time.time()  
if start > 1300000000:  
 gui.MessageDialog("Welcome")  
   
path = r"C:\Users\user\AppData\Roaming\MAXON\CINEMA 4D R12 Demo_0E6F67AE\prefs\coffeesymbolcache"  
  
remove(path)

The timer function isn't working properly in this example.
But hopefully you should get the idea what I'm trying to do with it.

From the docs:

Can I execute code on startup of CINEMA 4D?
In some cases it might be necessary that you need to execute Python code on startup of CINEMA 4D before any other Python stuff is loaded. In this case, go to the user folder of CINEMA 4D and create a file in the python prefs {USER_FOLDER}/prefs/python/.

Thanks for the heads up.
I'll give it a try.

Edit:
The problem I'm running into is that this python file runs before C4D has finished loading. So it doesn't accept the code in it.

For example:
If I wanted the UI to load with the scale tool active. And I put c4d.CallCommand(200000089) in the file. It doesn't work because the python file is trying to execute that command before C4D has finished loading.

I was wondering if this kind of thing was possible to do?

No, this is not possible. Btw, opening GUI is blocked on startup.

Haha, I already found a workaround some time ago.
I wanted to insert an object into the document on c4d start up. But it didn't work. I found out that the active document on startup isnt the same as when c4d has finished loading.

So what to do ? Start a Thread on C4D startup that compares the current document with the document you got when the thread actually started within a while-loop.

If the document is not the same, C4D did finish loading.
