I created 4 buttons and want when the 1 button is pressed the other 3 will be 0 or False.

I use this piece of code:

import c4d
from c4d import gui

def main() :

obj = doc.SearchObject("Null")

if obj[c4d.ID_USERDATA,1] == 1:

obj[c4d.ID_USERDATA,1] = 1
obj[c4d.ID_USERDATA,2] = 0
obj[c4d.ID_USERDATA,3] = 0
obj[c4d.ID_USERDATA,4] = 0

if obj[c4d.ID_USERDATA,2] == 1:

obj[c4d.ID_USERDATA,1] = 0
obj[c4d.ID_USERDATA,2] = 1
obj[c4d.ID_USERDATA,3] = 0
obj[c4d.ID_USERDATA,4] = 0

if obj[c4d.ID_USERDATA,3] == 1:

obj[c4d.ID_USERDATA,1] = 0
obj[c4d.ID_USERDATA,2] = 0
obj[c4d.ID_USERDATA,3] = 1
obj[c4d.ID_USERDATA,4] = 0

if obj[c4d.ID_USERDATA,4] == 1:

obj[c4d.ID_USERDATA,1] = 0
obj[c4d.ID_USERDATA,2] = 0
obj[c4d.ID_USERDATA,3] = 0
obj[c4d.ID_USERDATA,4] = 1

c4d.EventAdd()

if I press from the last one (4 to 1) its working but does not want to go back. It sticks to the one I pressed last.
I tried putting it in a loop but still the same. _<_img src="http://www.c4dcafe.com/ipb/public/style_emoticons/default/ufogoldorak5.png" border="0" alt=":confused:" title=":confused:" /_>_

Remove the EventAdd() at the end. Apart from that I don't see what could be
wrong with your code. Maybe share the scene.

For semantic reasons, you might want to use if/elif and not if/if

Ah now I get your problem. Well it will set the value of button "4" to 0 when one of the buttons "1", "2" or "3" were enabled before. You can save the state of the last button and omitt it.

import c4d
from c4d import gui
  
last = -1
def main() :
    global last
    obj = doc.SearchObject("Null")
            
    if last != 1 and obj[c4d.ID_USERDATA,1] == 1:
        last = 1
        obj[c4d.ID_USERDATA,1] = 1
        obj[c4d.ID_USERDATA,2] = 0
        obj[c4d.ID_USERDATA,3] = 0
        obj[c4d.ID_USERDATA,4] = 0
                                 
    elif last != 2 and obj[c4d.ID_USERDATA,2] == 1:
        last = 2
        obj[c4d.ID_USERDATA,1] = 0
        obj[c4d.ID_USERDATA,2] = 1
        obj[c4d.ID_USERDATA,3] = 0
        obj[c4d.ID_USERDATA,4] = 0
           
    elif last != 3 and obj[c4d.ID_USERDATA,3] == 1:
        last = 3
        obj[c4d.ID_USERDATA,1] = 0
        obj[c4d.ID_USERDATA,2] = 0
        obj[c4d.ID_USERDATA,3] = 1
        obj[c4d.ID_USERDATA,4] = 0
                                 
    elif last != 4 and obj[c4d.ID_USERDATA,4] == 1:
        last = 4
        obj[c4d.ID_USERDATA,1] = 0
        obj[c4d.ID_USERDATA,2] = 0
        obj[c4d.ID_USERDATA,3] = 0
        obj[c4d.ID_USERDATA,4] = 1

Or, even simpler:

import c4d
from c4d import gui
  
last = -1
cycle_ids = [1, 2, 3, 4]
  
def reset(obj) :
    for id_ in cycle_ids:
        obj[c4d.ID_USERDATA, id_] = False
  
def main() :
    global last
    obj = doc.SearchObject("Null")
            
    for id_ in cycle_ids:
        if last == id_:
            continue
        if obj[c4d.ID_USERDATA, id_]:
            last = id_
            reset(obj)
            obj[c4d.ID_USERDATA, id_] = True
