I'm not sure how to add vote options into the plugin itself (looking at Melee Only plugin to figure out) but you can use this:
http://forums.alliedmods.net/showthread.php?p=633808
to set up a custom vote for Randomizer on or off. Here's what I came up with to put in the "configs/customvotes/tf2itemsrandomizer.vote.cfg" for that plugin (automatically goes into the voting commands section of admin menu):
Code:
"tf2items_randomizer"
{
"title" "Turn TF2Items Randomizer {!tf2items_rnd_enabled|onoff}?"
"type" "onoff"
"admin" "sm_vote"
"cmd" "tf2items_rnd_enabled #1"
"params"
{
"1" "onoff"
}
}
I highly suggest you read the instructions for the plugin, as I came up with the above config in about two minutes and it might not be right.
EDIT: Also in 0.9 (still testing!) I improved some stuff, added a /tf2items_rnd_enable command to set the tf2items_rnd_enabled cvar to 1 (as well as ..._disable for 0).
If the tf2items_rnd_fix_spy cvar is at 2, you won't undisguise if you attack with sapper or the Disguise kit or Bonk! or Crit a cola or Sandvich or Dalokohs. Please remind me of anything else that doesn't attack to add to this "safe list".
I also tried fixing ubers, but I have not tested that yet, so that's why 0.9 is still in testing
