BaseList2D.GetData(self)

Returns a copy of the object’s container.

Return type

c4d.BaseContainer

Returns

The container reference.

BaseList2D.GetDataInstance(self)

This method returns the original container of the object.

The container is only alive as long as the host object is alive.

If you access the container even the host object is dead, Python will raise a ReferenceError.

The elements of the container are type protected when you set touch them via GeListNode.__setitem__(),

that means, you can just overwrite an element with a new object when its of the same type. When you want to overwrite the element with another type, you need to delete the previous element

with del(bc[ELEMENT_ID]), or use the manual BaseContainer.Set* methods.

Raises

• ReferenceError – If the container is dead. The container is just alive as long as the host object is alive. Access to a dead container leads to this error.

• TypeError – When you set an element of the wrong expected type.

Return type

c4d.BaseContainer

Returns

The original container reference.

BaseList2D.SetData(self, bc, add=True)

Sets the object container.

By default the contents of bc are merged with the existing container.

You can control this behavior with add.

Note

Do not forget to send a C4DAtom.Message() if you change any settings.

Parameters

• bc (c4d.BaseContainer) – The container.

• add (bool) – If this is True the values are merged, otherwise the old values are discarded.

Return type

c4d.BaseContainer

Returns

The container reference.

BaseList2D.ClearKeyframeSelection(self)

Clears the current keyframe selection.

BaseList2D.FindKeyframeSelection(self, id)

Checks if id is included in the keyframe selection.

Parameters

id (c4d.DescID) – The description ID to check.

Return type

bool

Returns

True if the given id is selected, otherwise False.

BaseList2D.KeyframeSelectionContent(self)

Checks if there are any active keyframe selections.

Note

This is not the same as BIT_ACTIVE, it is the possibility to restrict autokeyframing to certain description parameters.

See “Animation->Add Keyframe Selection” in the Attributes Manager.

Return type

bool

Returns

True if there is a keyframe selection, otherwise False.

BaseList2D.SetKeyframeSelection(self, id, selection)

Sets the keyframe selection status of id to selection.

Parameters

id (c4d.DescID) – The description ID to set.

Returns

True to select the key, otherwise id is selected, otherwise False.

Get the layer data for this object.

Changed in version R21: xref added to the dictionary.

Parameters

• doc (c4d.documents.BaseDocument) – The document.

• rawdata (bool) – Usually GetLayerData() takes special global modes like SOLO Layer automatically into account. But if you want to see the original layer values without any additional global changes you can set rawdata to True to get them.

Return type

dict{solo: bool, view: bool, render: bool, manager: bool, locked: bool, generators: bool, expressions: bool, animation: bool, color: Vector, xref: bool}

BaseList2D.GetLayerObject(self, doc)

Get the layer of this object.

• data (dict{solo: bool, view: bool, render: bool, manager: bool, locked: bool, generators: bool, expressions: bool, animation: bool, color: c4d.Vector, xref: bool}) – The new layer data. it is possible to leave values in the dictionary out.

Return type

bool

Returns

True if successful, otherwise False.

BaseList2D.SetLayerObject(self, layer)

BaseList2D.GetFirstShader(self)

Returns the first shader of the object.

Note

Normally you don’t have to deal with this list. But if you want to create or modify shader trees via the API you need to read the following lines:

• If you are programming shader links you need to make sure that every shader is referenced only once; it is not allowed that a shader is referenced multiple times.

• If the referencing object is a shader the referenced shader must be a child of it, otherwise it must be inserted via InsertShader().

• Example 1: A tag references a shader. The shader must be inserted into the tag using tag.InsertShader().

• Example 2: A shader (A) references another shader (B): shader B must be a child of shader A.

Return type

Optional[c4d.BaseList2D]

Returns

The first shader of the object, or None if there is no shader.

BaseList2D.InsertShader(self, shader, pred=None)

shader = c4d.BaseList2D(c4d.Xbitmap)
material.InsertShader(shader)

# Link the shader in the color channel.

This is done through Flags, and GetInfo returns these flags.

>>> op
<c4d.BaseObject object called Cube/Cube with ID 5159 at 1694956664448>
>>> op.GetInfo()
268435460
>>> # To make this output useful, we have to use a bitmask.
>>> op.GetInfo() & c4d.OBJECT_MODIFIER
0
>>> op.GetInfo() & c4d.OBJECT_GENERATOR
4

Return type

int

Returns

The flags. This is the same as the info parameter of the registration function of the registration function of the NodeData.

BaseList2D.TransferGoal(self, dst, undolink)

Transfer goals from this object to dst.

This changes all internal links that point to this object to point to dst instead.

Parameters

• dst (c4d.BaseList2D) – The destination

• undolink (bool) – This has to be set to False. Private.

BaseList2D.GetNLARoot(self)

Private.

BaseList2D.Scale(self, scale)

Scale the object.

Parameters

scale (float) – The size.

BaseList2D.Edit(self)

Triggers the edit action for this object.

Note

For most types this brings up the node in the attributes manager.

Some still show a separate dialog.

Return type

bool

Returns

False if an error occurred, otherwise True.

BaseList2D.SetAnimatedParameter(self, track, id, t_data1, t_data2, mix, flags)

Normally not used. Used by the animator to set the interpolated value along with the right and left values.

New in version R23.105.

Parameters

• track (c4d.CTrack) – The animation track. The caller owns the pointed track.

• id (c4d.DescID) – The ID of the animated parameter.

• t_data1 (Any) – The first data.

• t_data2 (Any) – The second data.

• mix (float) – The mix value between t_data1 and t_data2

• flags (int) –

  Flags:

  DESCFLAGS_SET_NONE	None.
  DESCFLAGS_SET_PARAM_SET	Parameter set.
  DESCFLAGS_SET_USERINTERACTION	Set when the GUI is calling SetParameter(). This is the only time when SetParameter() is allowed to use user interaction elements (e.g. open dialogs, display messages etc.).
  DESCFLAGS_SET_DONTCHECKMINMAX	No check is internally done if the parameter passed is within the [min/max] range of the description, to save some time.
  DESCFLAGS_SET_DONTAFFECTINHERITANCE	No parameter inheritance, for render settings and post effects only.
  DESCFLAGS_SET_FORCESET	Forces the set value without GetParameter()/Compare. Use only for calls where for sure the value was changed!
  DESCFLAGS_SET_DONTFREESPLINECACHE	Private. New in version R16.038.
  DESCFLAGS_SET_INDRAG	Gadget (e.g. Slider) in dragging mode (not finished). Only used when DESCFLAGS_SET_USERINTERACTION is set. New in version R17.053.

Returns

True if the animated parameter was set, otherwise False.

Return type

bool

BaseList2D.GetAnimatedParameter(self, id, flags)

Normally not used. Used by the animator to set the interpolated value along with the right and left values.

New in version R23.105.

Parameters

• id (c4d.DescID) – The ID of the animated parameter.

• flags (int) –

  Flags:

  DESCFLAGS_GET_NONE	None.
  DESCFLAGS_GET_PARAM_GET	Parameter retrieved.
  DESCFLAGS_GET_NO_GEDATADEFAULTVALUE	If set, the C++ GeData default type will not be initialized for C4DAtom.GetParameter().
  DESCFLAGS_GET_NO_GLOBALDATA	Private.

Returns

A tuple of the first data, the second data and the mix value between both data.

Return type

Tuple[Any, Any, float]
