The "scripting tutorial" appears to be utterly useless.
After the first lesson you can make a function that does absolutely nothing, or you could if you knew where to put the code, how to package an Add-On or use the console. You keep referencing "Torque" with no relation to Blockland and how the Torque Game Engine is related and you don't actually explain anything which might be relevant to coding something useful.
What, exactly, is a function line and why do you keep talking about them?
