Declaration

public static NativeArray<PolygonGeometry> CreatePolygons(ReadOnlySpan<Vector2> vertices, PhysicsTransform transform, Allocator allocator);

Parameters

Parameter Description
vertices The vertices to create the polygons from.
transform The transform used to specify where the geometry is positioned.
allocator The memory allocator to use for the results. This can only be Allocator.Temp, Allocator.TempJob or Allocator.Persistent.

Returns

NativeArray<PolygonGeometry> The created polygon geometries. This NativeArray must be disposed of after use otherwise leaks will occur. The exception to this is if the array is empty.

Description

Create multiple PolygonGeometry from a set of vertices. The vertices are assumed to produce a closed loop but can describe a concave shape if required. There must be at least 3 vertices. A limit is imposed on small vertex distances so be aware that this overload uses a vertex scale of Vector2.one so consider using the overload which allows you to increase this if required.


Declaration

public static NativeArray<PolygonGeometry> CreatePolygons(ReadOnlySpan<Vector2> vertices, PhysicsTransform transform, Vector2 vertexScale, Allocator allocator);

Parameters

Parameter Description
vertices The vertices to create the polygons from.
transform The transform used to specify where the geometry is positioned.
vertexScale The scaling to be applied to the vertices.
allocator The memory allocator to use for the results. This can only be Allocator.Temp, Allocator.TempJob or Allocator.Persistent.

Returns

NativeArray<PolygonGeometry> The created polygon geometries. This NativeArray must be disposed of after use otherwise leaks will occur. The exception to this is if the array is empty.

Description

Create multiple PolygonGeometry from a set of vertices. The vertices are assumed to produce a closed loop but can describe a concave shape if required. There must be at least 3 vertices. A limit is imposed on small vertex distances so it is recommended that scaling is applied here rather than on the returned geometry so geometry is not discarded due to it being invalid.


Declaration

public static NativeArray<PolygonGeometry> CreatePolygons(ReadOnlySpan<Vector2> vertices, PhysicsTransform transform, Vector2 vertexScale, float radius, bool useDelaunay, Allocator allocator);

Parameters

Parameter Description
vertices The vertices to create the polygons from.
transform The transform used to specify where the geometry is positioned.
vertexScale The scaling to be applied to the vertices.
radius The radius to apply to all generated polygons. Note that this will likely mean that the same polygon region defined by the vertices will not match.
useDelaunay Whether Delaunay tessellation will be used.
allocator The memory allocator to use for the results. This can only be Allocator.Temp, Allocator.TempJob or Allocator.Persistent.

Returns

NativeArray<PolygonGeometry> The created polygon geometries. This NativeArray must be disposed of after use otherwise leaks will occur. The exception to this is if the array is empty.
