Public Function GetContacts ( 
	objectA As CollisionObject,
	objectB As CollisionObject
) As ContactSet

public:
ContactSet^ GetContacts(
	CollisionObject^ objectA, 
	CollisionObject^ objectB
)

member GetContacts : 
        objectA : CollisionObject * 
        objectB : CollisionObject -> ContactSet 

Parameters

objectA

Type: DigitalRune.Geometry.CollisionsCollisionObject
The first collision object.

objectB

Type: DigitalRune.Geometry.CollisionsCollisionObject
The second collision object.

Return Value

If both collision objects are part of this CollisionDomain, then this method returns the currently cached contacts sets (which are stored in ContactSets). The contact sets are only updated, when Update(TimeSpan) is called. If the objects have moved since the collision domain was updated last, the contact information will not be up-to-date. In this case you need to call Update(TimeSpan) again before calling GetContacts(CollisionObject) to get up-to-date results.

If one collision object is not part of this CollisionDomain, then this method automatically calculates the new contact information.

If both collision objects are part of this CollisionDomain, then the returned contact sets are managed by the domain. You must not modify or recycle the contact sets! However, if any collision object is not part of this CollisionDomain, the returned contact sets are not managed by the domain. The contact sets can be modified. When they are no longer needed, they should be recycled to avoid unnecessary memory allocations. For example:

foreach (ContactSet contactSet in myCollisionDomain.GetContacts(objectA, objectB))
{
  // Check contact set.
  ...

  Debug.Assert(objectA.Domain != myCollisionDomain || objectB.Domain != myCollisionDomain);
  foreach(var contact in contactSet)
    contact.Recycle();
  contactSet.Recycle();
}
