I want to add selected objects at selected layer

To my mind it should be in the following way:

1. select object
2. press the button of script
3. select layer from the list of layers

How to add all layers in custom menu If this variant is right?

Hello for everyone! How to add selected objects at selected layer in layer mager?!!

@ferdinand

edit: I restored your image, we will answer the posting tomorrow [ferdinand]

@mogh I didn't know about this function
@ferdinand Thank you a lot for your detailed response. I will chek posts which you recommended

Hello guys! Is it real to check everything in layer (objects, materials, tags) and delete layer if its empty?

@ferdinand

Script add a null in center of world coordinates. I want to change it, i described what i want to do in pictures.

I added Mike's code, because i wanted to make 2 options for Step 2:

• First option — script add axis poins of selected objects in center.
• Second option — script add axis poins of selected objects in center but in the lowest position in Y coordinate. Mike's script could do this but just for one object. If i select objects more than one i get a message: "AttributeError: 'NoneType' object has no attribute 'GetAllPoints'".

I'm sorry for my English...

@ferdinand , thank you a lot!
When i tried to fix my code i used Mike Udin's example, but i couldn't understand why this code didn't work with multiple objects. I've got next message: "AttributeError: 'NoneType' object has no attribute 'GetAllPoints'".

I supposed my script to set selected objects' axis points in the center for each other. After that the script should create a null between all axis points.

import c4d

def main():
    
    ps = op.GetAllPoints() #Points in Local coordinates List
    m = op.GetMg() #Object Global Matrix

    center = op.GetMp() #Local coordinates center: https://tinyurl.com/wed88cn
    rad = op.GetRad() # Geometry radius: https://tinyurl.com/tb6vn64
    
    center -= c4d.Vector(0,rad.y,0) #Move down axis to lowest point. Comment this line to keep axis in a center 
    
    center *= m #Convert to Global coordinates center

    new_m = c4d.Matrix(m) #Copy matrix
    new_m.off = center #Change its center

    loc_m = ~new_m * m #Get local matrix

    op.SetAllPoints([loc_m.Mul(p) for p in ps])
    op.SetMg(new_m)
    
    op.Message(c4d.MSG_UPDATE)
    c4d.EventAdd()


if name == 'main':
    main()

edit: This topic has been forked from How to fix the bug of objects position in script by @ferdinand

Guys! Please, help. I cannot fix this problem.

The main idea of ​​this script is:

1. add selected objects and materials of these objects to the layer
2. insert all objects under null.
   But position of objects changes. How to fix it?

import c4d

def main():

    doc.StartUndo()


    layer = c4d.documents.LayerObject()
    # Set layer name (another option tp set the name)
    # Get the invisible root layer
    layerRoot = doc.GetLayerObjectRoot()
    # Insert the layer under the parent
    layer.InsertUnder(layerRoot)

    name = layer.GetName()
    rvalue = c4d.gui.RenameDialog(name) # rename
    print(rvalue)
    layer [c4d.ID_BASELIST_NAME] = rvalue
    #layer.DelBit(c4d.BIT_ACTIVE)

    null_obj = c4d.BaseObject(c4d.Onull)
    null_obj [c4d.ID_LAYER_LINK] = layer
    null_obj [c4d.ID_BASELIST_NAME] = rvalue
    doc.InsertObject(null_obj)


    doc.AddUndo(c4d.UNDOTYPE_NEWOBJ, layer)
    doc.AddUndo(c4d.UNDOTYPE_NEWOBJ, null_obj)

    s = doc.GetSelection()
    vp = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_NONE)


    for obj in vp:

        print obj

        obj [c4d.ID_LAYER_LINK] = layer
        obj.InsertUnder(null_obj)

        obj_mat_tags = [t for t in obj.GetTags() if t.IsInstanceOf(c4d.Ttexture)]

        for tag in obj_mat_tags:

            mat = tag.GetMaterial()
            print mat
            mat [c4d.ID_LAYER_LINK] = layer


    doc.EndUndo()
    c4d.EventAdd()

if __name__ == '__main__':
    main()

I use r21 version of c4d.

@ferdinand Thank you a lot for your help! I'm really sorry for organization of my post. Could you point out on my mistakes in tagging?

Dear community!

I want to create length port for spline node but I can’t find correct command for it.
How to get id of port in form like this
c4d.GV_PORT_OUTPUT, [c4d.ID_BASEOBJECT_REL_POSITION,c4d.VECTOR_X]

Mike, thank you a lot!

@m_magalhaes Thank you for answer!

Hello for everyone. Is it real to set up parameters like a position and rotation for all selected nodes by python?

def main():
    nodes = [] 
    root = nodeMaster.GetRoot() 
    for node in root.GetChildren():
        if node.GetBit(c4d.BIT_ACTIVE): 
        ##place for setting parameter##

If its real, could you write a command which set up x position in input for example

Hello guys! I know how to merge a scene with a current project. But i have no idea how to insert scene under parent with coordinats of this parent.

I want to create custom nulls thats why i want to it. What should i add in this code if i want insert scene under object?

import c4d
def main():
    doc.StartUndo() # Start recording undos
    path = "C:\Users\Jamaletdinov.r\Desktop\ArrowR.c4d" 
    flags = c4d.SCENEFILTER_OBJECTS | c4d.SCENEFILTER_MATERIALS | c4d.SCENEFILTER_MERGESCENE 
    c4d.documents.MergeDocument(doc, path, flags) 
    c4d.EventAdd()
    doc.EndUndo() 
if __name__=='__main__':
    main()

@ferdinand Sorry for the late reply. Yes you understood me correctly. Will this be fixed in new c4d versions?

Hello for every one. Does anybody know is it real to set up value for selected user data and for all user data in object?

@cairyn Thank you again. I will check your patreon

@cairyn
For example, we have 20 layers and i need to change visibility just for 2 layers in this list. That's what i meant when i talked about selected layers.

I tried to use same code but it showed to me first layer in list....while i want to work with active layers which i have selected.

And i wanted to ask which command delete layer?

Sorry for stupid questions, but SDK a little bit unobvious.

@cairyn, i don't understand just one thing how should i change a code if i want to do it with selected objects not for all.

import c4d

def visitLayer(layer):
if layer == None: return
print (layer.GetName())
doc.AddUndo(c4d.UNDOTYPE_CHANGE, layer)
layer [c4d.ID_LAYER_VIEW] = 1
visitLayer(layer.GetDown())
visitLayer(layer.GetNext())

def main():
doc.StartUndo()
first = doc.GetLayerObjectRoot().GetDown()
visitLayer (first)

doc.EndUndo()
c4d.EventAdd()

if name=='main':
main()

It’s too bad, but thank you for your answer Manuel.

Hello for everybody!

I want to show all User Data of object in HUD. Is it real to make it by python,
i checked SDK but didn't find something about User data HUD.

Is it real or not?

P.S. I found an information about viewport in general (visibility of polygons, joints and so on) but nothing about user data hud.
