Can be usefull. ;D
Yes, that's true.
But, instead of being a douche. Im actually going to help him.
A .dts file is a model file.
All the models in-game such as vehicles, weapons, and bricks are .dts files.
So, your wondering how to make a .dts. Well, you need to have a 3d model first.
A good, FREE, 3d modeling program is Blender.
After you have a model completed, you can export this model to .dts format. After doing this, you can bring it ingame using a script to make it a item, or vehicle. Etc etc.
So, making a dts isn't as easy as you might have thought. But its basically a format of 3d model that the torque game engine uses. (The engine blockland runs off of.)
