Object

ArrayOccluder3D

Remarks

ArrayOccluder3D stores an arbitrary 3D polygon shape that can be used by the engine's occlusion culling system. This is analogous to ArrayMesh, but for occluders.

See OccluderInstance3D's documentation for instructions on setting up occlusion culling.

Properties

indices

The occluder's index position. Indices determine which points from the vertices array should be drawn, and in which order.

Note: The occluder is always updated after setting this value. If creating occluders procedurally, consider using ArrayOccluder3D.set_arrays instead to avoid updating the occluder twice when it's created.

var indices : PackedInt32Array = PackedInt32Array()

Property Value

PackedInt32Array

Remarks

• void set_indices(PackedInt32Array value)
• PackedInt32Array get_indices

vertices

The occluder's vertex positions in local 3D coordinates.

Note: The occluder is always updated after setting this value. If creating occluders procedurally, consider using ArrayOccluder3D.set_arrays instead to avoid updating the occluder twice when it's created.

var vertices : PackedVector3Array = PackedVector3Array()

Property Value

PackedVector3Array

Remarks

• void set_vertices(PackedVector3Array value)
• PackedVector3Array get_vertices

Methods

set_arrays(PackedVector3Array, PackedInt32Array)

Sets indices and vertices, while updating the final occluder only once after both values are set.

void set_arrays(PackedVector3Array vertices, PackedInt32Array indices)

Parameters

vertices PackedVector3Array

indices PackedInt32Array
