thebolt helped me some on IRC.
He suggested csEngineTools::FindScreenTarget.
So I used it, and it detects if a wall is clicked on, but it can't find Cubard
at all:
The updated code is found here:
http://rapidshare.com/files/139322800/xyzim.zip.html
If you compile it(which only takes a few seconds) You will confirm when you
click on stuff it always says,"Wall"
The old code I used before would tell me which part of Cubard you clicked on.
Any help?

The code does compile fine.
The problem is when I click on anything, It sees the mesh as NULL.
I zipped up my project here:
http://rapidshare.com/files/139295540/xyzim.zip.html
The snippet of code I need help with is at: //start
It is the code provided here. The reason I provide my small project along side
is so if someone wanted to help me, they could test out clicking on Cubard.
For someone who understands how to use a mouse to click on objects using
hitbeam, this should be no problem. My real problem is that Peter Amstutz
wrote this code for me so it is like a black box to me. I do not understand
the old code so I can't figure out how to update it.
This code is important to me because it allows me to finish my animation maker.
I had my animation maker finished before and I provided it out as open source.
You can see the results of some of the animations I made at
www.roamingdragon.com if you download the OLD demo.
Thank you Crystal Space community,
Jim
