Note: This mod requires config changes to work, it is not plug & play - although it is simple to setup.

This mod will generate a config file under the servers profile folder (profiles/CZ Mods/CZ Underground Bases 2.0)

You can place the basement entrances using either the config file with coordinates, or you can place them with the DayZ Editor.

*Important* - You may need to change the rules for object placement in CFGGameplay file to place items inside the bunker, without these changes it may only allow you to drop objects instead of place them.

JSON Settings - BasementSettings.json

basementCenterAreaPosition - You may need to change the 2nd value which is the height of the basement to match server requirements (1000-5000)

basementCenterAreaRadius - there is generally no need to change this.

basementCleanupAfterInactiveDays - this controls how long a player will keep basement if they never enter it in days.

smallBasementClassName - this is the class name for the item that unlocks small basements, most users will leave this as it is.

largeBasementClassName - this is the class name for the item that unlocks large basements, most users will leave this as it is.

keyRequiredToEnterBasementEachTime - 0 for off, 1 for on. Controls if the user MUST have a key in their hand to enter a basement.

damageKeyOnUse - 0 for off, 1 for on. If this is on the key object will be damaged by the percentage set in this file.

damagePercentOnUse - This is the amount of damage the key will get for each use if the option above is enabled. In percentage 0-100

playerLosesKeyOnUse - 0 for off, 1 for on. If this is on, each use of the keycard the player will lose the item entirely, cannot be used with damageKey option.

keyRequiredToManageBasement - 0 for off, 1 for on. If this is on the player must have a key in hand to change basement name, change PIN or delete basement.


JSON Settings - AdminSettings.json

This file is simple, it takes your steam ID and for all people that have steam ID listed in this file will have access to the Basement Admin menu using the keybind set within the game, the keybind will not work unless your steam ID is in this file.


JSON Settings - DoorLocations.json

This file controls where doors are placed, if you prefer you can just place them using DayZ Editor, but please do not spawn them in with COT, VPP Admin Tools etc.
You can however use the object builder function in VPP Admin tools to place them if you wish.

ClassName - this is the actual object, do not change this, it will break the mod.
Position - the world position to place the door when the server starts.

Remember to include commas between each new record here, just copy and paste, but the last record MUST NOT have a comma.

Hope these instructions were helpful.
