Scripts:Vehicle Class Limit

Introduction
This ModManager script prevents use of certain vehicle classes.
Whenever a player enters one of the forbidden vehicles a 10 second timer is started if it's not already running.
When the timer is activated it checks all the players and tries to punish the trespassers. As it's almost impossible to kill a player serverside (the player could be standing near a supply drop, health pack, heli landing pack etc.) the script decreases the health of player and the occupied vehicle, hoping for a fast explosion.
The timer is deactivated if no players were in the forbidden vehicles.
Prerequisites
ModManager or BF2CC
Install
- unzip the file (or copy and paste into mm_climit.py) to admin/modules in your Battlefield 2 server install.
- if necessary, edit the file and change the forbidden classes (by default the forbidden classes are Armor, Helicopter and Aircraft)
- change your modmanager.con and include the following line:
''modmanager.loadModule "mm_climit"''

===== About =====
This ModManager script prevents use of certain vehicle classes.
Whenever a player enters one of the forbidden vehicles a 10 second timer is started if
it's not already running.
When the timer is activated it checks all the players and tries to punish the trespassers.
As it's almost impossible to kill a player serverside (the player could be standing near
a supply drop, health pack, heli landing pack etc.) the script decreases the health of
player and the occupied vehicle, hoping for a fast explosion. ;)
The timer is deactivated if no players were in the forbidden vehicles.
