Features This modification adds Keycards System to the game. You can use it to add Keycard Doors, Keycard Buildings, as well as Loot Crates linked to these doors. Currently the modification contains: 36 Keycard Doors and Gates 15 Keycards and 2 Keycard Holders 4 Loot Crate variants (5 colors each) You can also add regular DayZ building to this system to make its doors work as Keycard Doors. Configuration After the first server startup, the mod will create CustomKeycards folder in the profiles folder of your server. Inside this folder you will find: Logs Folder Locations Folder for Keycard Doors LootTables Folder for your Loot Tables. Static_Locations Folder for Keycard Buildings itemsRename.json config More info about this folders and configs can be found on mod's wiki Inside mod's folder you can also find .INFO folder with: types.xml file for Keycards ClassNames.txt with all ClassNames Default Configs with links to specific mod's wiki pages If you need help with editing your configs, please go to Mod's Wiki Important Info Placing doors using DayZ Editor or other mods/tools (like VPPAdminTools) will break Keycard Doors -> they will become regular doors!!! You MUST add them via config files!!! If you are using VPPAdminTools to get Keycard Doors coordinates, you need to have this checkbox enabled in Object Manager for Keycard Doors to show up.

Where the load comes from

Counts how often each hook is dispatched and how many timers stay alive, not what the code inside does. Some rates are order-of-magnitude estimates; the methodology lists which.

Where this mod runs often

Hooks on per-frame and high-rate surfaces, with what their bodies call. Body work, not the hook itself, is what costs frame time.

Other findings

What this report can tell you

Which vanilla methods the mod hooks, which of them drop the chain, how often each hook fires, and which risky calls sit inside hot hooks.

What it cannot

How long hook bodies take, network cost, or engine-side load. Measured across live fleets, most server lag comes from the engine and world state, not mod script chains — a light footprint does not clear a mod of lag, and a heavy one does not convict it. Methodology.

Everything else

All 11 overrides

Surface is the dispatch tier the rubric can price (— = unpriced); server is whether the override exists on a dedicated server; super() shows whether the vanilla chain is preserved on a server.
