From TDN

You can find the syntax documentation and some background information on the Torquescript language here: Torque Game Engine Documentation

Don't be confused by the "preview" in the background, it is there to represent that we are working on more docs. However, we might want to get rid of that watermark finally.

Also check out Joel Baxter´s quick TorqueScript reference & Ron Yacketta´s TorqueScript command reference in particular.

And there are even more Tutorials available here on the site. Check out the main TGE Tutorials page, which anyone can see.
