PhysicsShapeGroup2D.GetShapeVertex

参数

返回

Vector2 Returns the specified shape vertex.

描述

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: Get all the shape vertices using GetShapeVertices Get all the shape group vertices using GetShapeData Create the PhysicsShapeGroup2D with explicit shapes and vertices lists using the shape group Constructor See Also: SetShapeVertex.

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

        // 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);
    }
