Tough question on objects in perspective, plz help

Hi all,

I posted this question originally in the programming forum and I had a feeling (thanks to Stefan *Shaderman* Greven) that it's related to the graphics forum maybe because of the way Torque works.

Q: Just like the function onCollision can be used to find out the object the player collided with, is there a function to find out the objects that come in to the player's perspective?

Thanks to everyone, in advance...
