Struct EdgeLookup
An edge composed of both the local index and common index.
This is useful when comparing vertex indexes that are coincident. Coincident vertices are defined as vertices that are share the same coordinate space, but are separate values in the vertex array. ProBuilder tracks these coincident values in the @"UnityEngine.ProBuilder.ProBuilderMesh.sharedIndexes" array. A "common" (also called "shared") index is the index of a vertex in the sharedIndexes array.

Syntax
public struct EdgeLookup : IEquatable<EdgeLookup>Constructors
EdgeLookup(Int32, Int32, Int32, Int32)
Create an edge lookup from common and local edges.
Declaration
public EdgeLookup(int cx, int cy, int x, int y)Parameters
| Type | Name | Description |
|---|---|---|
| System.Int32 | cx | Common edge x. |
| System.Int32 | cy | Common edge y. |
| System.Int32 | x | Local edge x. |
| System.Int32 | y | Local edge y. |
EdgeLookup(Edge, Edge)
Create an edge lookup from a common and local edge.
Declaration
public EdgeLookup(Edge common, Edge local)Parameters
| Type | Name | Description |
|---|---|---|
| Edge | common | An edge composed of common indexes (corresponds to @"UnityEngine.ProBuilder.ProBuilderMesh.sharedIndexes"). |
| Edge | local | An edge composed of vertex indexes (corresponds to mesh vertex arrays). |
Properties
common
Declaration
public Edge common { get; set; }Property Value
| Type | Description |
|---|---|
| Edge | Commmon edges point to the vertex index in the sharedIndexes array. |
local
Declaration
public Edge local { get; set; }Property Value
| Type | Description |
|---|---|
| Edge | Local edges point to an index in the vertices array. |
Methods
Equals(Object)
Compares each EdgeLookup common edge (does not take into account local edge differences).
Declaration
public override bool Equals(object obj)Parameters
| Type | Name | Description |
|---|---|---|
| System.Object | obj | The EdgeLookup to compare against. False if obj is not an EdgeLookup type. |
Returns
| Type | Description |
|---|---|
| System.Boolean | True if the common edges are equal, false if not. |
Overrides
Equals(EdgeLookup)
Compares each EdgeLookup common edge (does not take into account local edge differences).
Declaration
public bool Equals(EdgeLookup other)Parameters
| Type | Name | Description |
|---|---|---|
| EdgeLookup | other | The EdgeLookup to compare against. |
Returns
| Type | Description |
|---|---|
| System.Boolean | True if the common edges are equal, false if not. |
GetEdgeLookup(IEnumerable<Edge>, Dictionary<Int32, Int32>)
Create a list of EdgeLookup edges from a set of local edges and a sharedIndexes dictionary.
Declaration
public static IEnumerable<EdgeLookup> GetEdgeLookup(IEnumerable<Edge> edges, Dictionary<int, int> lookup)Parameters
| Type | Name | Description |
|---|---|---|
| System.Collections.Generic.IEnumerable<Edge> | edges | A collection of local edges. |
| System.Collections.Generic.Dictionary<System.Int32, System.Int32> | lookup | A shared index lookup dictionary (see ProBuilderMesh.sharedIndexes). |
Returns
| Type | Description |
|---|---|
| System.Collections.Generic.IEnumerable<EdgeLookup> | A set of EdgeLookup edges. |
GetEdgeLookupHashSet(IEnumerable<Edge>, Dictionary<Int32, Int32>)
Create a hashset of edge lookup values from a collection of local edges and a shared indexes lookup.
Declaration
public static HashSet<EdgeLookup> GetEdgeLookupHashSet(IEnumerable<Edge> edges, Dictionary<int, int> lookup)Parameters
| Type | Name | Description |
|---|---|---|
| System.Collections.Generic.IEnumerable<Edge> | edges | A collection of local edges. |
| System.Collections.Generic.Dictionary<System.Int32, System.Int32> | lookup | A shared index lookup dictionary (see ProBuilderMesh.sharedIndexes). |
Returns
| Type | Description |
|---|---|
| HashSet<EdgeLookup> | A HashSet of EdgeLookup edges. EdgeLookup values are compared by their common property only - local edges are not compared. |
