CollisionDetection.UpdateContacts Method

CollisionDetectionUpdateContacts Method

Updates the contact information in the given contact set.

Namespace: DigitalRune.Geometry.Collisions
Assembly: DigitalRune.Geometry (in DigitalRune.Geometry.dll) Version: 1.18.0.0 (1.18.2.14427)

Syntax

C++

Copy

public void UpdateContacts(
	ContactSet contactSet,
	float deltaTime
)

Public Sub UpdateContacts ( 
	contactSet As ContactSet,
	deltaTime As Single
)

public:
void UpdateContacts(
	ContactSet^ contactSet, 
	float deltaTime
)

member UpdateContacts : 
        contactSet : ContactSet * 
        deltaTime : float32 -> unit

Parameters

contactSet: Type: DigitalRune.Geometry.CollisionsContactSet
The contact set containing the last known contacts.
deltaTime: Type: SystemSingle
The time step size in seconds. (The elapsed simulation time since UpdateClosestPoints(ContactSet, Single) or UpdateContacts(ContactSet, Single) was last called for this contact set.)

Exceptions

Exception	Condition
ArgumentNullException	contactSet is .

Remarks

If two objects move, the contact information will usually change and has to be updated. Using the contact set containing the last known contacts, this method can compute the new contacts faster than GetContacts(CollisionObject, CollisionObject) if the poses of the objects haven't changed drastically.
