Doesn't Torque use its own C like scripting language? If you want to learn C++ then surely, just go and learn it properly without bothering with another proprietary "language" in-between. The Torque C-script might be similar to C++, but it's still not going to actually be C++. Sure you get the source, so you can get in and dirty with the engine, but if you're capable of doing that I dare say you don't need it in the first place.
http://www.garagegames.com has it all.
And interestingly on the top listed game on the GG home page in the "Game Store" section was written in DBPro
That just about says it all really.
If you want to move to C++ in order to become a games programmer for a big software house, starting taking extra math and physics classes at school/college (if you still can) and worry less about the "visual" stuff and more about your ability to solve problems through code and optimisation.
If you're just doing this "for fun" then stop for a moment and ask yourself why so many professional games developers and artists are using the likes of DBP and Blitz for their pet hobby projects (which they often then go on to sell). The reason is time
