Vector2EqualityComparer

Use this class to compare two Vector2 objects for equality with NUnit constraints. Use the static Vector2EqualityComparer.Instance to have the calculation error value set to default 0.0001f. For any other error value, instantiate a new comparer object with the one argument constructor.

Static properties

Syntax	Description
Instance	A comparer instance with the default error value set to 0.0001f.

Constructors

Syntax	Description
Vector2EqualityComparer(float error)	Creates an instance with a custom error value.

Public methods

Syntax	Description
Equals(Vector2 expected, Vector2 actual)	Compares the actual and expected Vector2 objects for equality using the Utils.AreFloatsEqual method.

Example

[TestFixture]
public class Vector2Test
{
    [Test]
    public void VerifyThat_TwoVector2ObjectsAreEqual()
    {
        // Custom calculation error
        var actual = new Vector2(10e-7f, 10e-7f);
        var expected = new Vector2(0f, 0f);
        var comparer = new Vector2EqualityComparer(10e-6f);

        Assert.That(actual, Is.EqualTo(expected).Using(comparer));

        //Default error 0.0001f
        actual = new Vector2(0.01f, 0.01f);
        expected = new Vector2(0.01f, 0.01f);

        Assert.That(actual, Is.EqualTo(expected).Using(Vector2EqualityComparer.Instance));
    }
