說明

|
----
|
|
|
|
**ArrayOccluder3D** 儲存可供引擎遮擋剔除系統使用的任意 3D 多邊形形狀，概念上類似於 :ref:`ArrayMesh<class_ArrayMesh>`\ ，但專用於遮擋物。
|
|
|
|
設定方法請參閱 :ref:`OccluderInstance3D<class_OccluderInstance3D>` 文件。

遮擋物的索引位置。索引決定應從 :ref:`vertices<class_ArrayOccluder3D_property_vertices>` 陣列繪出哪些點及其繪製順序。
|
|
|
|
\ **注意：**\ 設定此值後遮擋物會立即更新。若以程式化方式建立遮擋物，建議改用 :ref:`set_arrays()<class_ArrayOccluder3D_method_set_arrays>` 以避免建立過程中更新兩次。
|
|
|
|
**Note:** The returned array is *copied* and any changes to it will not update the original property value. See :ref:`PackedInt32Array<class_PackedInt32Array>` for more details.

同時設定 :ref:`indices<class_ArrayOccluder3D_property_indices>` 與 :ref:`vertices<class_ArrayOccluder3D_property_vertices>`\ ，並於兩者皆完成後僅更新一次最終遮擋物。
