Hi kgbdino!
I have mapped for 2 years. I am not smart. I tried to understand “how to make a tank and stuff” some time ago. Had to give up. It is above and beyond my skill level.
Solution: Open a .map file that contains a tank and a truck (if you want a truck). Copy the .map file under a new name (i.e. “tank_prefab.map”). Then strip out everything except the tank and the necessary entities (such as the script_multiplayer entity).
OK, now you have a functional map with a tank that moves and behaves just like a real ET tank.
Copy and rename the .map (to for example “my_map.map”). Then start adding stuff, roads buildings. You also might want to change the path of the tank.
Compile and save. Hopefully it all works.
Where are .map files with tanks in it? The stock map Goldrush is included in your ET, and it comes in the form of a .map file. You can open it in the editor.
There might be other .map files out there on the web that contains nothing else than just the tank (and perhaps the truck)? If so, you can download and use them.
My best tip.
