aw yeah, with your help, I got it!

c4d.CallButton(simTag, c4d.RIGID_BODY_CACHE_BAKE)

works a treat, found the ID in dynrigidbodytag.str, which is in the modules folder.

alas, the code is less than perfect. the baking works if the tags are selected separately, but if i try to select them all at once only the first one bakes.

import c4d
from c4d import gui
#Welcome to the world of Python

def main() :
#gui.MessageDialog('Hello World!')

doc = c4d.documents.GetActiveDocument()
selected = doc.GetActiveTags()

#print "eeeeeoooaaaa"

for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
print simTag.GetName()
simTag[c4d.RIGID_BODY_ENABLED]=False

for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
#print simTag.GetTypeName()
simTag[c4d.RIGID_BODY_ENABLED]=True
c4d.CallButton(simTag, c4d.RIGID_BODY_CACHE_BAKE)
simTag[c4d.RIGID_BODY_ENABLED]=False

for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
#print simTag.GetTypeName()
simTag[c4d.RIGID_BODY_ENABLED]=True

if __name__=='__main__':

main()

works for me.

yes, your code bakes all the tags, though what I want to do is only have one rbd and one collider active at any one time. So the rigid bodies interact with the floor, but not each other.
The manual way of doing this is to only have one rbd enabled at a time when baking. that doesn't seem to be working for me when scripted.

hm,
that sounds funny. but with your explanation your code snippet does make more sense now.
will give it a look tomorrow, but for now i cannot come up with a reason for that behaviour.

edit : you should also try searching the forum on CallButton(). i am 75% sure that there was
going on some discussion / problems regarding this method and tags.

the problem seems like it can only evaluate one bake per time I run the script. Am I missing some sort of "commit" command for tags?

found the other thread i think you were referring to:
https://developers.maxon.net/forum/topic/6464/6947_load-edge-selection&KW=CallButton&PID=29059#29059

the gist of that thread was that CallButton wasn't safe and Nodedata.Message should be used instead. I've updated my script for that, but no luck. Only the first tag in the selection gets cached.

import c4d

def main() :

doc = c4d.documents.GetActiveDocument()
selected = doc.GetActiveTags()

for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
simTag[c4d.RIGID_BODY_ENABLED]=False

dc = {}
dc['id'] = c4d.DescID(c4d.RIGID_BODY_CACHE_BAKE)
for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
simTag[c4d.RIGID_BODY_ENABLED]=True
simTag.Message(c4d.MSG_DESCRIPTION_COMMAND, dc)
simTag[c4d.RIGID_BODY_ENABLED]=False

for simTag in selected:
if simTag.GetTypeName() == "Dynamics Body":
simTag[c4d.RIGID_BODY_ENABLED]=True

c4d.EventAdd()

if __name__=='__main__':
main()

first of all, as a side note - you do not have to define doc. it is already predefined. there are always
some variables predefined as doc (current document) or tp t(he documents particle system).

dynamics baking seems to have some problems with multi-selections. the code of yours is perfectly
fine. however, if you fake the step by step selection, it works as expected (at least for me).

import c4d
  
def main() :
    dc = {}
    dc['id'] = c4d.DescID(c4d.RIGID_BODY_CACHE_BAKE)
    tagSelection = doc.GetActiveTags()
  
    for tag in tagSelection:
        if tag.GetTypeName() == "Dynamics Body":
            tag[c4d.RIGID_BODY_ENABLED]=False
        else:
	    # remove unwanted tags from our selection
            tagSelection.remove(tag)
    
    for tag in tagSelection :
	# set the active tag
        doc.SetActiveTag(tag)
        tag[c4d.RIGID_BODY_ENABLED]=True
        tag.Message(c4d.MSG_DESCRIPTION_COMMAND, dc)
        tag[c4d.RIGID_BODY_ENABLED]=False
    
    for tag in tagSelection:
         tag[c4d.RIGID_BODY_ENABLED] = True  
               
if __name__=='__main__':
     main()
