2D Overlap Tests

Inside of the ImpulsePhysics::CollisionChecks2D namespace, you will find the following functions available to you to check for any possible overlap:

(All of these return a bool as value, with true meaning the two given 2D Primitives are overlapping.)

Point tests

• IsPointOnLine(Point2D, Line2D)
• IsPointInCircle(Point2D, Circle2D)
• IsPointInRectangle(Point2D, Rectangle2D)
• IsPointInOrientedRectangle(Point2D, RectangleOriented)

Line tests

• IsLineInsideCircle(Line2D, Circle2D)
• IsLineInsideRectnagle(Line2D, Rectangle2D)
• IsLineInsideOrientedRectangle(Line2D, RectangleOriented)

Circle tests

• CircleCircleCollision(Circle2D, Circle2D)
• CircleRectangleCollision(Circle2D, Rectangle2D)
• CircleOrientedRectangleCollision(Circle2D, RectangleOriented)

Rectangle tests

• RectangleRectangleCollision(Rectangle2D, Rectangle2D)
• RectangleRectangleCollisionSAT(Rectnagle2D, Rectangle2D) – similar to the above, but uses the SAT algorithm instead.

Oriented Rectangle tests

• OrientedRectangleRectangleCollision(RectangleOriented, Rectangle2D)
• OrientedRectangleOrientedRectangleCollision(RectangleOriented, RectangleOriented)
