Summary
Build and upgrade your own base with modular structures, material progression, crafting stations and PIN-protected doors.
Official Workshop description
TLL_BuildingSystem – The Last Light Base Building
Build a place to survive. TLL_BuildingSystem brings modular construction, material progression, base ownership, PIN access, specialized storage and persistent base management to Arma Reforger. Developed for The Last Light and Project Ashfall.
MODULAR CONSTRUCTION
Create your layout with foundations, triangle foundations, ceilings, walls, half walls, staircases, doorways and window walls. Use the building manual to select pieces and view a placement preview before confirming construction. Snapping, rotation and adjustable foundation height help align your base with its surroundings. Placement is checked on the server, including support, authorized build areas and resource requirements.
FIVE MATERIAL TIERS
Progress through Wood, Stone, Copper, Iron and Titanium. Building and upgrading consume the required materials through the TLL resource economy. The base-upgrade system groups structure types and advances eligible pieces through the required tier progression, preventing stronger pieces from bypassing unfinished lower-tier work. Upgrade checks preserve the original pieces when requirements cannot be met.
BASE CONSOLE & OWNERSHIP
Deploy a base console to establish a 50-metre horizontal building zone with a starter foundation. The owner and authorized builders can construct within that zone. Placement restrictions account for the player's position and the structure's footprint, and prevent unauthorized construction inside another base. One owner cannot deploy a second active console elsewhere.
PIN ACCESS & SHARED BUILDING
Set a base PIN to authorize other players to build in your zone. Incorrect PINs are rejected, and changing the base PIN revokes previously granted teammate access. Doors and base consoles use their supported ownership and PIN-locking interactions. Access checks run on the server.
SPECIALIZED STORAGE LOCKERS
Deploy lockers using their matching portable notebook kits. Preview and rotate each locker before placement; the kit is consumed only after successful placement and saving.
- Weapon Locker: weapons, ammunition and supported weapon accessories.
- Military Equipment Locker: equipment classified as military gear by the storage rules.
- General Locker: other supported supplies and general items.
Filters also inspect nested contents, preventing a bag from bypassing the locker's category rules. Owners and console-authorized builders can access their base storage. An item's assigned category determines its compatible locker; canteens currently fall under military equipment.
PERSISTENT BASES & CONTENTS
The base save system records supported building pieces, their position and orientation, ownership, base membership, lock state, authorized identities and expiry information. Supported locker contents retain their prefab tree, nested items, magazine ammunition and saved item health where applicable.
Remaining canteen water is also preserved, distinguishing empty, partially filled and full containers. Older saves without water fields remain readable and retain prefab defaults for those items; water quantities that were never saved cannot be recovered.
SEVEN-DAY BASE MAINTENANCE
New consoles receive seven real days before expiry. An authorized owner or builder can refresh the base to extend its deadline to seven days from the refresh. The deadline continues while players are offline.
Expired bases are removed with their bound structures, lockers and stored contents. Membership-based cleanup preserves neighboring bases, including nearby or overlapping structures belonging to another base. A base cannot be refreshed after its expiry deadline has passed.
SERVER MOD INTEGRATION
A versioned server-side API allows trusted Enfusion mods to inspect base metadata and request destruction under their own conditions. It includes expiry-only removal by default, explicit server-policy removal, an administrator-checked path, audit reasons and stale-base checks. This is an in-game scripting API, not a public HTTP service.
REQUIREMENTS & COMPATIBILITY
Requires TLL_LootSystem and the appropriate BuildingSystem setup in your scenario. Use compatible versions of the related TLL addons. Player inventory persistence and garage cargo are handled by their separate systems.
CURRENT STATUS
Updated for Arma Reforger 1.9.0.37. Local validation passed 217 checks covering storage, permissions, locker placement, saved-content restoration in a new play session, console/foundation construction, destruction and expiry behavior. Dedicated-server restart and remote-player testing remain pending; a local play-session reload is not a full server restart test.
