Declaration

public void GetShapeData(List<PhysicsShape2D> shapes, List<Vector2> vertices);

Parameters

shapes A list that will be populated with a copy of all the shapes in the PhysicsShapeGroup2D.
vertices A list that will be populated with a copy of all the vertices in the PhysicsShapeGroup2D.

Description

Gets a copy of both the shapes and vertices in the PhysicsShapeGroup2D.

NOTE: Because this is a copy, changing the specified shapes and vertices lists afterwards will not change the PhysicsShapeGroup2D.

using UnityEngine;
using UnityEngine.Assertions;

public class Example : MonoBehaviour { void Start() { // Create a shape group. var shapeGroup = new PhysicsShapeGroup2D();

// Add a Circle to the shape group. var circleShapeIndex = shapeGroup.AddCircle ( center: new Vector2(-2f, 3f), radius: 1f );

// Add a Capsule to the shape group. var capsuleShapeIndex = shapeGroup.AddCapsule ( vertex0: Vector2.down, vertex1: Vector2.up, radius: 0.5f );

// Validate the contents. Assert.AreEqual(PhysicsShapeType2D.Circle, shapeGroup.GetShape(circleShapeIndex).shapeType); Assert.AreEqual(PhysicsShapeType2D.Capsule, shapeGroup.GetShape(capsuleShapeIndex).shapeType);

// Fetch the shapes and vertices from the shape group. var shapes = new List<PhysicsShape2D>(); var vertices = new List<Vector2>(); shapeGroup.GetShapeData(shapes, vertices);

// Fetch the Circle shape and validate shape and vertex. var circleShape = shapes[circleShapeIndex]; Assert.AreEqual(PhysicsShapeType2D.Circle, circleShape.shapeType); Assert.AreApproximatelyEqual(1f, circleShape.radius); Assert.AreEqual(new Vector2(-2f, 3f), vertices[circleShape.vertexStartIndex]);

// Fetch the Capsule shape and validate shape and vertices (2). var capsuleShape = shapes[capsuleShapeIndex]; Assert.AreEqual(PhysicsShapeType2D.Capsule, capsuleShape.shapeType); Assert.AreApproximatelyEqual(0.5f, capsuleShape.radius); Assert.AreEqual(Vector2.down, vertices[capsuleShape.vertexStartIndex]); Assert.AreEqual(Vector2.up, vertices[capsuleShape.vertexStartIndex + 1]); } }

Declaration

public void GetShapeData(NativeArray<PhysicsShape2D> shapes, NativeArray<Vector2> vertices);

Parameters

shapes A NativeArray that will be populated with a copy of all the shapes in the PhysicsShapeGroup2D.
vertices A NativeArray that will be populated with a copy of all the vertices in the PhysicsShapeGroup2D.

Description

Gets a copy of both the shapes and vertices in the PhysicsShapeGroup2D.

NOTE: Because this is a copy, changing the specified shapes and vertices arrays afterwards will not change the PhysicsShapeGroup2D.
