struct in UnityEngine.LowLevelPhysics2D
/
Implemented in:UnityEngine.Physics2DModule
The geometry of a closed convex polygon. See PhysicsBody.CreateShape.
| Property | Description |
|---|---|
| defaultGeometry | Get the default Polygon. |
| Property | Description |
|---|---|
| centroid | The centroid of the polygon. |
| count | The number of polygon vertices. |
| isValid | Check if the geometry is valid or not. |
| normals | The geometry normal stored in a ShapeArray. |
| radius | The external radius for rounded polygons. |
| vertices | The geometry vertices stored in a ShapeArray. |
| Constructor | Description |
|---|---|
| PolygonGeometry | Create a default Polygon. See PolygonGeometry.defaultGeometry. |
| Method | Description |
|---|---|
| CalculateAABB | Calculate the AABB of the geometry. |
| CalculateMassConfiguration | Calculate the mass configuration of the geometry. |
| CastRay | Calculate if a world ray intersects the geometry. See CastResult. |
| CastShape | Calculate if a cast shape intersects the geometry. Initially touching shapes are treated as a miss. You should check for overlap first if initial overlap is required. See CastShapeInput and CastResult. |
| ClosestPoint | Calculate the closest point on this geometry to the specified point. |
| Intersect | Check the intersection between this geometry and another. |
| InverseTransform | Inverse-Transform the geometry. |
| OverlapPoint | Calculate if a point overlaps the geometry. |
| Transform | Transform the specified geometry. |
| Validate | Get a validated version of the geometry, if possible. |
| Method | Description |
|---|---|
| Create | Create a Polygon from the specified vertices. The number of vertices must be in the range 3 to PhysicsConstants.MaxPolygonVertices. |
| CreateBox | Create a Polygon as a four-sided box. |
| CreatePolygons | Create multiple Polygons 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. |
| DeleteVertex | Delete a vertex from the geometry returning a new geometry with updated normals and centroid. |
| InsertVertex | Insert a vertex into the geometry returning a new geometry with updated normals and centroid. |
