public void SetShapeVertex(int shapeIndex, int vertexIndex, Vector2 vertex)

Parameters

shapeIndex

int
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

int
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.

vertex

Vector2
The value to set the shape vertex to.

Remarks

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

Assert.AreEqual(Vector2.down, vertex0);        Assert.AreEqual(Vector2.up, vertex1);        // Set the shape vertices in the shape group.        shapeGroup.SetShapeVertex(shapeIndex, vertexIndex: 0, vertex: Vector2.left);        shapeGroup.SetShapeVertex(shapeIndex, vertexIndex: 1, vertex: Vector2.right);        // Fetch the shape vertices from the shape group.        vertex0 = shapeGroup.GetShapeVertex(shapeIndex, vertexIndex: 0);        vertex1 = shapeGroup.GetShapeVertex(shapeIndex, vertexIndex: 1);        // Validate the Capsule vertices.        Assert.AreEqual(Vector2.left, vertex0);        Assert.AreEqual(Vector2.right, vertex1);    }}
