Police Vest Mod Base

Police vest is an item one could pick up, granting resistance against damage as long as the vest's condition is above zero (Condition value is shown on inventory).

Having multiple yields the same resistance, but your character will continue to have protection should one fail.
It is arbitrary selection as to which vest will be applied damage upon, so the best way to preserve the condition of a vest is to not have it on you.

This is a base mod providing radial icon & the fundamental script logic, and is designed for further modding. You can write a mutator that extends this, or make a map with this, do be sure to include this as required item when you publish your mod.
As an example, I have made a mod that spawns police vests around map with resources this mod provides, which is available here:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3257013215&searchtext=

local armor_item = SpawnEntityFromTable("item_custom",
{
icon = "nmo_irradiated/vest", // Icon displayed on inventory radial, this mod base provides one already.
label = "Vest (100%)", // Doesn't matter, will be dynamically updated anyway
model = "models/items/vest/police_vest.mdl", // Model of the police vest
weight = 120, // Custom weight value, 120 weighs slightly more than a first aid kit
vscripts = "nmo_irradiated/armorNewVscript.nut" // Script component comes with the mod, do not change.
});

Place an "item_custom" entity in your map, specify the following fields:
icon = "nmo_irradiated/vest", // Icon displayed on inventory radial, this mod base provides one already.
label = "Vest (100%)", // Doesn't matter, will be dynamically updated anyway
model = "models/items/vest/police_vest.mdl", // Model of the police vest
weight = 120, // Custom weight value, 120 weighs slightly more than a first aid kit
vscripts = "nmo_irradiated/armorNewVscript.nut" // Script component comes with the mod, do not change.

sv_vest_rand_condition_min: Minimum condition police vest spawns in
sv_vest_rand_condition_max: Maximum condition police vest spawns in
