Declaration

public Vector2 GetShapeVertex(int shapeIndex, int vertexIndex);

Parameters

shapeIndex The index of the shape stored in the PhysicsShapeGroup2D. The shape index is zero-based with the shape group having a quantity of shapes specified by shapeCount.
vertexIndex The index of the shape vertex stored in the PhysicsShapeGroup2D. The vertex index is zero-based with the shape having a quantity of vertex specified by PhysicsShape2D.vertexCount.

Returns

Vector2 Returns the specified shape vertex.

Description

Gets a single vertex of a shape. The vertex index is zero-based with the shape having a quantity of vertex specified by PhysicsShape2D.vertexCount.

NOTE: When accessing multiple vertices, it is more efficient to do one of the following:

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

// Fetch the shape vertices from the shape group. var vertex0 = shapeGroup.GetShapeVertex(shapeIndex, vertexIndex: 0); var vertex1 = shapeGroup.GetShapeVertex(shapeIndex, vertexIndex: 1);

// validate the Capsule vertices. Assert.AreEqual(Vector2.down, vertex0); Assert.AreEqual(Vector2.up, vertex1); } }
