Searching for nearby objects - TGB 1.7.4

Hi there,
I'm trying to implement the Microbes functionality from TXB on C# (http://www.garagegames.com/docs/torqueX/official/content/documentation/TorqueX%202D/Tutorials/Microbes.html) using TGB and TorqueScript.

Looking for nearby objects, C# has the function "FindObjects", and for TS I started using the function InitContainerRadiusSearch, since it implements a similar functionality, but when I ran my application I got the following error:

--> "Unable to find function InitContainerRadiusSearch"

and then I realized that InitContainerRadiusSearch isn't implemented on TGB...

There is any function that I could use on TGB instead of InitContainerRadiusSearch to lookup for nearby objects?
Or it's impossible to implement the Microbes functionality on TGB with TS?

Thanks in advance!
