A delegate object for SKPhysicsWorld that provides events when SKPhysicsBodys begin and end contact with each other.

Remarks

The following example reverses gravity when a SKPhysicsBody named "Sphere" encounters one of the bodies named either "TopWall" or "BottomWall":

public override void DidBeginContact(SKPhysicsContact contact)
{
	if(contact.BodyA.Node.Name == "Sphere" || contact.BodyB.Node.Name == "Sphere")
	{
		if(contact.BodyA.Node.Name == "BottomWall" || contact.BodyB.Node.Name == "BottomWall" || contact.BodyA.Node.Name == "TopWall" || contact.BodyB.Node.Name == "TopWall")
		{
			world.Gravity = new CGPoint(0, -world.Gravity.Y);
		}
	}
}
