public int AddCapsule (Vector2 vertex0, Vector2 vertex1, float radius);

パラメーター

vertex0 The position of one end of a capsule shape. This point represents the center point of a logical circle at the end of a capsule.
vertex1 The position of the opposite end of a capsule shape. This point represents the center point of a logical circle at the opposite end of a capsule.
radius The radius of the capsule defining a radius around the vertex0 and vertex1 and the area between them.

戻り値

int Returns the shape index the shape was added to in the PhysicsShapeGroup2D. This index is used as the main reference when retrieving a shape.

説明

Adds a capsule shape (PhysicsShapeType2D.Capsule) to the shape group.

A capsule shape is comprised of a single edge shape defined by two vertices (vertex0 and vertex1 ) and a radius that extends around the length of the edge and around the vertices.

NOTE: A capsule forms a closed shape and does have an interior therefore its interior is detectable by physics queries etc.

public class Example : MonoBehaviour { void Start() { CreateShape(); GetShapeFromCollider(); }

// Create a custom shape. void CreateShape() { // Create a shape group. var shapeGroup = new PhysicsShapeGroup2D();

// Add a Capsule. var shapeIndex = shapeGroup.AddCapsule ( vertex0: Vector2.down, vertex1: Vector2.up, radius: 0.5f );

// Fetch the actual shape created. var physicsShape = shapeGroup.GetShape(shapeIndex);

// Validate what we created. Assert.AreEqual(PhysicsShapeType2D.Capsule, physicsShape.shapeType); Assert.AreApproximatelyEqual(0.5f, physicsShape.radius); Assert.AreEqual(2, physicsShape.vertexCount); }

// Get a physics shape from a Collider. void GetShapeFromCollider() { // Fetch the collider. var collider = GetComponent<CapsuleCollider2D>();

// If the collider is not active and enabled then we'll get no shapes. // Let's just quit if not. if (!collider.isActiveAndEnabled) return;

// Configure the collider. collider.size = new Vector2(1f, 2f);

// Create a shape group. var shapeGroup = new PhysicsShapeGroup2D();

// Get the collider shapes. collider.GetShapes(shapeGroup);

// Fetch the actual shape. var physicsShape = shapeGroup.GetShape(0);

// Validate what we retrieved. Assert.AreEqual(PhysicsShapeType2D.Capsule, physicsShape.shapeType); Assert.AreApproximatelyEqual(0.5f, physicsShape.radius); Assert.AreEqual(2, physicsShape.vertexCount); } }
