Example 6 with Transformation

use of org.spongepowered.api.util.transformation.Transformation in project SpongeCommon by SpongePowered.

the class TransformationTest method performRotationTest.

private Transformation performRotationTest(final Rotation rotation, final Vector3d original, final Vector3d expected, final Vector3d origin, final int rotateTimes) {
    // given this builder
    final SpongeTransformationBuilder transformationBuilder = new SpongeTransformationBuilder();
    // when rotating
    for (int i = 0; i < rotateTimes; ++i) {
        transformationBuilder.rotate(rotation);
    }
    final Transformation transformation = transformationBuilder.origin(origin).build();
    // then perform the transformation
    final Vector3d result = transformation.transformPosition(original);
    Assertions.assertEquals(expected, result, "Did not get expected rotation.");
    return transformation;
