C4DObjectList Class Reference

#include <lib_editortools.h>

Detailed Description

A class representing a set of objects in the editor.
Most often allocate a copy of this object and then let SelectionListCreate() fill it.

Note

Has to be created with Alloc() and destroyed with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Member Function Documentation

Alloc() [1/2]

static C4DObjectList* Alloc ( )

static

Allocates an object list. Destroy the allocated object list with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Returns

The allocated object list, or nullptr if the allocation failed.

Alloc() [2/2]

static C4DObjectList* Alloc ( const maxon::SourceLocation &  )

static

Allocates an object list. Destroy the allocated object list with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Returns

The allocated object list, or nullptr if the allocation failed.

Free()

static void Free ( C4DObjectList *&  ptr )

static

Destructs object lists allocated with Alloc(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters

[in,out]

ptr

The object list to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

GetCount()

Int32 GetCount

(

)

Get the number of objects stored in the list.

Returns

The number of objects.

GetObject()

BaseObject* GetObject

(

Int32

num

)

Gets a stored object pointer by index.

Parameters

[in]

num

An object index: 0 <= num < GetCount()

Returns

The object at index num. Cinema 4D owns the pointed object.

GetZ()

Float GetZ

(

Int32

num

)

Gets the Z distance to a stored object by index.

Parameters

[in]

num

An object index: 0 <= num < GetCount()

Returns

The Z distance to the object at index num.

GetPolyIdx()

Int32 GetPolyIdx

(

Int32

num

)

Gets the polygon index of a stored object by index.

Parameters

[in]

num

An object index: 0 <= num < GetCount()

Returns

The polygon index.

AddObject()

Bool AddObject	(	BaseObject *	op,
		Float	z,
		Int32	polynum
	)

Adds an object to the list at a certain Z distance.

Parameters

[in]	op	The object to add. The caller owns the pointed object.
[in]	z	The Z distance to op.
[in]	polynum	The number of polygons.

Returns

true if successful, otherwise false.

Flush()

void Flush

(

)

Clears the object list.
