This is my attempt at making the tanks from Frontline able to be driven by players. It has two parts: a basic entity setup in the map that determines how players get into tanks, and a sourcemod plugin that makes the tanks work properly.
The final goal for this is to make some prefabs people can use in their maps, with the server mod only affecting maps that were built for it. Right now I've only just got some of the basic functions of the tanks working, but ultimately I'm planning to have the tanks operate differently depending on which class is in them, and possibly create a few new game-modes centered around controlling vehicles.
The .bsp for the example map and the .smx for the plugin are both in the zip folder, along with the decompiled versions for anyone who wants to take a look at how everything works.
Both the mod and the map are needed for this to work; the map will be glitchy if the soucemod plugin isn't running, and the sourcemod plugin only activates if the map tells it to (or if anyone gets in a bumper car. I'm planning on fixing that compatibility issue in a future version).
