Hi everyone,

I'm looking for a way to access the switches on the active layer in the Layer Browser.

Is this possible?

I'm just starting out with Python for C4D, so a lot of this is very new to me.

Thanks.

You can use doc.GetLayerObjectRoot() to access the root of layers (only call GetDown() here!!).
If root.GetDown()!=None layers exist in the document, otherwise not. You can browse the hierarchy
of layers and check GetBit(c4d.BIT_ACTIVE) on each layer if its enabled.

Cheers, Sebastian

Thanks, that got me access to the layer name at least. Phew!

This is what I have so far:

import c4d, math, random  
from c4d import bitmaps, documents, gui, modules, plugins, storage, utils  
  
def main() :  
    c4d.CallCommand(100004738) # New Layer  
    root = doc.GetLayerObjectRoot()  
  
    root.GetDown().SetName("NEWLAYER")
      
if __name__ == '__main__':  
main()

What I'm trying to do is change the switches on the layer, like Solo, Visible, etc.

I think I need to use SetLayerData, but cannot for the life of me get it to work.

Also, is there a more elegant way to create a layer other than CallCommand?

Hello. I found this bit of code on CGSociety. I cannot get it to work though. Neither can I find any documentation about ID_LAYER_LINK.

Can anyone help me out here?

def main() :  
	    obj = doc.GetActiveObject()  
	    layer = obj[c4d.ID_LAYER_LINK]  
	    color = layer[c4d.ID_LAYER_COLOR] = c4d.Vector(0,0,0)# Sets layer color to black  
	    c4d.EventAdd()  
	    print color

I am (95%) convinced that GetLayerData and SetLayerData are not implemented yet. Can anyone please confirm this?

Using this code:

import c4d, math, random  
from c4d import*
 
def main() :         
  c4d.CallCommand(100004738) # New Layer  
  c4d.CallCommand(100004736) # Add Objects to Layer      
    
  lay = op.GetLayerObject(doc)  
  lay.SetName("NEWLAYER")  
  lay.GetLayerData(doc, True)  
    
  c4d.EventAdd()
 
if __name__ == '__main__':      
  main()

throws the error "AttributeError: 'c4d.documents.LayerObject' object has no attribute 'GetLayerData'"
****
Am I using it incorrectly?

Yes, these methods are currently not implemented yet.

Thanks again.

I'm curious how a newcomer is supposed to accomplish anything when the documentation is so badly misleading. The earlier function GetLayerObjectRoot() that you mentioned doesn't even exist in the docs, even though it's implemented. The reverse is true for Set and GetLayerData. They're in the docs, but don't actually exist.

Am I looking at the wrong docs? How is it that you are aware of these things? Are you a Maxon developer?

Please note, the current documentation is still preliminary and will be updated. If a function is not part of the documentation, it was added in the latest C4D update.
