Detailed Description

A helper for safety interaction through the contact point buffer.

Member Function Documentation

Next() [1/2]

bool Quantum.CollisionInfo2D.ContactPointIterator2D.Next ( out FPVector2  contactPoint )

inline

Iterates through the contact points of a collision.

Parameters

contactPoint

The current contact point. Default if the iteration is over.

Returns

true if there is still a contactPoint .

while(info.ContactPoints.Next(out var cp) {
  Draw.Circle(cp, FP._0_10);
}

Next() [2/2]

bool Quantum.CollisionInfo2D.ContactPointIterator2D.Next ( out FPVector2  contactPoint, out FPVector2  contactNormal  )

inline

Iterates through the contact points of a collision, also accessing the contact normal.

Parameters

contactPoint	The current contact point. Default if the iteration is over.
contactNormal	The contact normal. Default if the iteration is over.

Returns

true if there is still a contactPoint and contactNormal .

while(info.ContactPoints.Next(out var contactPoint, out var contactNormal) {
   Draw.Circle(contactPoint, FP._0_10);
   Draw.Ray(contactPoint, contactNormal);
}

NextUnsafe()

bool Quantum.CollisionInfo2D.ContactPointIterator2D.NextUnsafe ( out FPVector2 *  contactPoint, out FPVector2 *  contactNormal, out bool  invertedNormal  )

inline

Iterates through the contact points of a collision, also accessing the contact normal. The pointers access the fields directly in the collision manifold structure and modifications done to it will affect the collision resolution.

Parameters

contactPoint	The current contact point. Default if the iteration is over.
contactNormal	The contact normal. Default if the iteration is over.
invertedNormal	If the contact normal is inverted from the perspective of the main entity in the callback.

Returns

true if there is still a contactPoint and contactNormal .

while(info.ContactPoints.NextUnsafe(out var contactPoint, out var contactNormal, out var invertedNormal) {
   Draw.Circle(*contactPoint, FP._0_10);
   Draw.Ray(*contactPoint, invertedNormal ? -(*contactNormal) : *contactNormal);
}

ResetIterator()

void Quantum.CollisionInfo2D.ContactPointIterator2D.ResetIterator ( )

inline

Resets the iterator.

Property Documentation

Count

readonly int Quantum.CollisionInfo2D.ContactPointIterator2D.Count

get

The number of contact points on this collision.

Average

readonly FPVector2 Quantum.CollisionInfo2D.ContactPointIterator2D.Average

get

The average contact point on this collision.

First

FPVector2 Quantum.CollisionInfo2D.ContactPointIterator2D.First

getset

The first contact point computed on this collision.

Contact points are computed in NO particular order.

Current

FPVector2 Quantum.CollisionInfo2D.ContactPointIterator2D.Current

getset

The current contact point iterated. Next(out Photon.Deterministic.FPVector2) must have been called at least once and must have returned true in the latest call.

Contact points are computed in NO particular order.

ContactNormal

FPVector2 Quantum.CollisionInfo2D.ContactPointIterator2D.ContactNormal

getset

The collision normal of the manifold.
