Summary

This release addresses various fixes and improvements that were missed in the 3.0 release. Despite introducing some breaking changes, I decided to classify this as a minor release rather than version 4.0, as all the breaking changes pertain to the same systems as the 3.0 release.

FirstContact / ContactEnded System Overhaul: 

Previously, the FirstContact was only reported for Colliders and not for CollisionObjects. The system has now been split into two separate systems: one for Collider pairs and one for CollisionObject pairs.

• CollisionObjects:
  • A FirstContact between two CollisionObjects is reported once any Collider of one contacts any Collider of the other CollisionObject.
  • The ContactEnded() function for the CollisionObject is called once all contacts between all of the Colliders have ended.
• Colliders:
  • A FirstContact between two Colliders is reported the first time they contact (no contact in the previous frame).
  • The ColliderContactEnded() function is called once the contact ends (contact in the previous frame but no contact in the current frame).

Other Changes:

• Namespace Changes:
  • CollisionObject moved to the CollisionSystem namespace.
• Class Removals:
  • ContactEndedInformation class removed.
  • Contact class removed.
• Function Parameter Changes:
  • ContactEnded(CollisionObject other) function parameters changed.
  • ColliderContactEnded(Collider self, Collider other) function parameters changed.
• CollisionInformation Improvements:
  • CollisionInformation now includes a FirstContact member, reported only for the two involved CollisionObjects, separate from any FirstContact reporting between Colliders.
  • General improvements and cleanup of CollisionInformation, including new functions.
  • New functions for Exists, Find, and FindAll CollisionPoints.
  • New functions for finding Closest, Furthest, and Combined CollisionPoint.
• Collision Improvements:
  • Functions for Exists, Find, and FindAll CollisionPoints added.
• CollisionPoints:
  • GetClosest/Furthest/FacingTowards functions now skip invalid collision points
• Renaming:
  • GetAverageCollisionPoint() renamed to GetCombinedCollisionPoint() in multiple classes.
• ResolveCollision Update:
  • CollisionObject.ResolveCollision() is now called for each generated CollisionInformation instead of receiving a list of CollisionInformation.
