形状类型决定了此 PhysicsShape2D 如何使用顶点和半径。
有关不同形状类型的更多信息,请参阅 PhysicsShapeType2D 文档。

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 );
// Fetch the shapes. var circleShape = shapeGroup.GetShape(circleShapeIndex); var capsuleShape = shapeGroup.GetShape(capsuleShapeIndex);
// Validate the shape types. Assert.AreEqual(PhysicsShapeType2D.Circle, circleShape.shapeType); Assert.AreEqual(PhysicsShapeType2D.Capsule, capsuleShape.shapeType); } }
