DMG Doors v0.1
When enabled this plugin adds damage to sliding doors, or sliding and hinged doors. The amount of damage dealt is also configurable. The main purpose for the writing of the plugin was to prevent message flooding caused by players getting stuck in a door, which sometimes results in all nearby players getting dropped from the server, but it's also just kinda fun.
If you would like to try out this plugin you can find a list of servers running it at the following link:
Cvars (First value is default):
dmgdoors < 2 (all doors) | 0 (disabled) | 1 (only sliding doors) >
dmgdoors_dmg < 9999 | ... > : How much damage the doors will do.
Changes to cvars only take affect after a map change.
