i solved the problem by setting user data
colReporter.setUserData("Checkpoint: "+(++num));
on the 'gate' object. When collision occurs, u just retrieve the data
from the node:
Node trigObj = trigPath.getNode(trigPath.nodeCount()-1);
Object userData = trigObj.getUserData();
if (userData != null)
{
if (userData instanceof String)
{
String info = (String)userData;
if (info.startsWith("Checkpoint:") && !info.equals(""))
{
int i = info.lastIndexOf(' ');
....
Note, that what u get during collision is a SceneGraphPath object. The
outmost object in the path is the object u armed collision detector
with and if u set user data for an object other than the one u armed 4
collision detection, then u should retrieve appropriate object from
the trigPath during collision.

NS> Hi,
NS> I'm writing a little car racing game and I need to know when my car finished the
race. So I thougt when my car(a simple box) collides with the goal then the race is
finished. But how can I find
NS> out with which object the car collides? For all other collisions it is not
important to know which object the car hit so I used WakeuponCollisionEntry(Node). Do
I have to use
NS> WakeuponCollisionEntry(SceneGraphPath) to find out the object I hit?
NS> Thanks for all help!
