See Also

top

Get all selected ProBuilderMesh components. Corresponds to Selection.gameObjects.Select(x => x.GetComponent<ProBuilderMesh>().Where(y => y != null);.

Declaration
public static IEnumerable<ProBuilderMesh> top { get; }
Property Value
Type Description
IEnumerable<ProBuilderMesh>

An array of the currently selected ProBuilderMesh components. Does not include children of selected objects.

totalCommonVertexCount

Declaration
public static int totalCommonVertexCount { get; }
Property Value
Type Description
Int32

Get the number of all selected vertices across the selected ProBuilder meshes, excluding coincident duplicates.

totalEdgeCount

Declaration
public static int totalEdgeCount { get; }
Property Value
Type Description
Int32

Sum of all selected ProBuilderMesh object edgeCount properties.

totalFaceCount

Declaration
public static int totalFaceCount { get; }
Property Value
Type Description
Int32

Sum of all selected ProBuilderMesh object faceCount properties.

totalTriangleCountCompiled

Declaration
public static int totalTriangleCountCompiled { get; }
Property Value
Type Description
Int32

Get the sum of all selected ProBuilder compiled mesh triangle counts (3 indexes make up a triangle, or 4 indexes if topology is quad).

totalVertexCount

Declaration
public static int totalVertexCount { get; }
Property Value
Type Description
Int32

Get the number of all selected vertices across the selected ProBuilder meshes.
Remarks

This is the ProBuilderMesh.vertexCount, not UnityEngine.Mesh.vertexCount. To get the optimized mesh vertex count, see totalVertexCountCompiled for the vertex count as is rendered in the scene.

Declaration
public static event Action objectSelectionChanged
Event Type
Type Description
Action
