Vector3EqualityComparer
Use this class to compare two Vector3 objects for equality with NUnit constraints. Call Vector3EqualityComparer.Instance comparer to perform a comparison with the default calculation error value 0.0001f. To specify a different error value, use the one argument constructor to instantiate a new comparer.

Description |
bool Equals(Vector3 expected, Vector3 actual) |
Compares the actual and expected Vector3 objects for equality using Utils.AreFloatsEqual to compare the x, y, and z attributes of Vector3. |
Example
[TestFixture]
public class Vector3Test
{
[Test]
public void VerifyThat_TwoVector3ObjectsAreEqual()
{
// Custom error 10e-6f
var actual = new Vector3(10e-8f, 10e-8f, 10e-8f);
var expected = new Vector3(0f, 0f, 0f);
var comparer = new Vector3EqualityComparer(10e-6f);
Assert.That(actual, Is.EqualTo(expected).Using(comparer));
//Default error 0.0001f
actual = new Vector3(0.01f, 0.01f, 0f);
expected = new Vector3(0.01f, 0.01f, 0f);
Assert.That(actual, Is.EqualTo(expected).Using(Vector3EqualityComparer.Instance));
