Adapted the code to the latest API changes in SD.

Adapted code to the latest SD API change.

Adapted code to an API change in SD.

Renamed ContinuousCircleLineSegmentTest to MovingCircleLineSegmentTest.

Changed LineSegment in the same way as Circle.

Added some more info to Circle's documentation.

Updated LineSegment's documentation.

Adapted the new concept for Circle a bit by adding a default radius. Also added documentation.

Changed the way Circle works. It no longer has a mutable attribute (its radius) but rather defines an abstract method returning the radius.

Simplified SimpleNarrowPhaseSpec by using mock objects where possible and removing unnecessary data.

Renamed Vec2D to Vector2.

Fixed some code formatting.

Renamed LineSegment.d to LineSegment.direction.

Set position constraints in Paddle that prevent the paddles from leaving the screen.

Adapted Paddle to an API change in SD.

Fixed some code formatting.

Simplified paddle movement.

Adapted border to a recent SD API change.

Fixed code formatting.

Removed Collision.

Changed NarrowPhase to return a Contact, not a Collision.

Removed the obsolete attributes in PositionConstraint.

Made use of the more fine-grained position constraint attibutes in PositionConstraintSolver.

Added more attributes to PositionConstraint that will allow for more fine-grained control of the constrained positions. Once PositionConstraintSolver uses these new attributes, the old attributes can be removed.

Removed unused imports in World.

Fixed some code formatting.

Fixed some code formatting style.

Fixed some code formatting.

World: Moved position constraint solving to the end of the step to make sure position constraints are satisfied, even after contact solving.

SimpleContactSolver: Implemented a tolerance value to make sure shapes are really moved out of each other, regardless of any rounding errors.

Fixed a bug in ElasticCollisionReaction. ElasticCollisionReaction would remove the contacts it processed from the Shape, even though they were still needed by SimpleContactSolver.

Removed impulse code from Body.

Removed CollisionSolver and ImpulseSolver.

Removed the last traces of CollisionSolver/ImpulseSolver from World.

Integrated CollisionDetector, ElasticCollisionReaction and SimpleContactSolver into World. Removed all the classes they made obsolete.

Added SimpleContactSolver, a contact solver that solves penetration and doesn't account for the three-body-problem yet.

Adjusted Netbeans settings.

Did some refactorings and comment updates in ContinuousCircleLineSegmentTest.

Changed the last of the examples in ContinuousCircleLineSegmentSpec to use radii of 2.

Minor documentation fix in ContinuousCircleLineSegmentTest.

Set version of maven-scala-plugin to 2.12.2.

Changed the circles used in the ContinuousCircleLineSegmentTest specification to circles with radius 2, where this was possible without triggering a bug.

Fixed a bug in ContinuousCircleLineSegmentTest where a relative movement parallel to the circle wouldn't be handled correctly.

Added InvalidVector, an object which represents an invalid vector.

Made us of ZeroVector in Vec2D code.

Added ZeroVector, an object that represents the zero vector.

Added a method that computes the factor between two linearly dependent vectors.

Added a method to Vec2D that determines if a vector is linearly independent from another.

Removed position vector from LineSegment. It has been redundant since Shape has been changed to extend Body.

Updated code formatting of LineSegmentSpec.

Refactored ContinuosCircleLineSegment's speficication a bit to make it more readable.

I also used "sphere" instead of "circles" in some places in ContinuousCircleLineSegmentTest. Fixed it.

For some reason I used the word "sphere" a lot where "circle" would have been applicable. Fixed this in ContinuousCircleCircleTest and its specification.

Fixed a bug in ContinuousCircleCircleTest. There would be an exception if the two circle centers had the same position in the beginning of the movement.

Updated documentation in ContinuousCircleCircleTest.

Updated Contact's documentation.

Fixed a typo.

Enhanced ContinuousCircleCircleTest. The contact point is now computed if the circles overlap initially.

Fixed ContinuousCircleCircleTest. It would compute incorrect normals and penetration depth in many cases (and by extension, incorrect contact points, since that comutation depends on the normal).

Fixed spelling errors in a code comment.

Fixed a bug in ContinuousCircleCircleTest where contacts between non-moving circles that were initially touching but not overlapping where not reported.

Fixed a bug in ContinuousCircleCircleTest, where the penetration depth would be computed incorrectly if the sphere centers had passed each other.

Performed some minor refactorings in ContinuousCircleCircleTest.

Added computation of the depth attribute to ContinuousCircleCircleTest.

Added the depth attribute to Contact.

Enhanced an example in ContactSpec that wasn't specifying the complete behaviour as implemented.

Enhanced documentation in Contact.

Fixed an example in ContactSpec that may have been specifying the wrong behaviour.

Reordered attributes in Contact.

Removed some unused imports in SimpleNarrowPhaseSpec.

Removed TestResult.

Changed ContinuousCircleCircleTest to return a Contact instead of TestResult.

Updated code formatting style in ContinuousCircleCircleTestSpec.

Changed CircleLineSegmentTest to return a Contact instead of a TestResult.

Removed some unused imports in SimpleNarrowPhaseSpec.

Removed TestResult.

Changed ContinuousCircleCircleTest to return a Contact instead of TestResult.

Updated code formatting style in ContinuousCircleCircleTestSpec.

Changed CircleLineSegmentTest to return a Contact instead of a TestResult.

Added the new attribute t to Contact.

Refactoring in Collision. Made use of -convert.

Refactored SimpleNarrowPhase specification.

Changed SimpleNarrowPhase to use constructor dependency injection instead of setter injection.

Added a new attribute to TestResult, depth, which represents the penetration depth.

Removed sanity-check of dt from World.

Removed Integrator, EulerIntegrator. Those were replaced by VerletIntegrator.

Integrated VerletIntegrator into World. Removed all unit tests that were conflicting with that change.

Implemented a StepPhase that performs elastic collision reaction.

A Shape's contacts can now be removed one-by-one. Before, they could only be cleared.

Coding style corrections in SimpleNarrowPhase specification.

Refactored SimpleNarrowPhase.

Converted Contact.inverse into the unary method "-".

Added a method to Contact that returns the inverse contact.

Minor refactorings in Contact's specification.

Fixed a type in Contact's specification.

Added a new Integrator, VerletIntegrator.

Added NetBeans configuration.

Added the new attribute acceleration to Body.

Minor correction.

Whitespace correction.

Coding style correction.

Improved the main loop.

Change the rendering code to make modifications to the scene graph synchronously.

Moved Score into the UI package.

Minor documentation update.

Reordered display setup code in Main a bit.

Fixed a build error that was introduced in one of the recent refactorings.

Reordered display setup code in Main.

Extracted ball display setup code into the class BallView.

Extracted paddle display setup into the class PaddleView.

Disabled null checking when compiling.

Reordered some setup code in Main.

Extracted border setup code into GameSetup.

Created a class for borders, Border.

Added some additional compiler arguments.

Moved Paddle and Ball into the sup-package game.

Extracted a part of the game setup code into a separate class.

Extracted key handling setup code into a separate class.

Extracted UI setup code into a separate class.

Made use of the new utility class in Main.

Added the object PiccoUtil, which contains an utility function for working with Piccolo.

Removed all wildcard imports.

Converted the KeyHandler test suite into a Specs specification.

Added a specification for KeyMap.

Code formatting correction in KeyMap.

Relaxed version requirement for dependency scala-library.

Simplified call to BroadPhase in CollisionDetector.

Changed parameter and return type of BroadPhase from List to Iterable.

Collision detection between circles and line segments was not correctly implemented in SimpleNarrowPhase. Fixed that.

Added another example to the SimpleNarrowPhase specification.

Minor corrections to the SimpleNarrowPhase specification.

Added contacts to Shape.

Moved Contact into package collision.shape.
