YAProxy

A lightweight DayZ framework (1.29+) for attaching user actions to furniture proxies baked into house models (sinks, fridges, cabinets, vending machines, …), which are not separate entities.

Credit: technique combines Zenarchist's ZenProxyFramework (action API / client→server position sync, invisible-entity persistence pattern) and the ShowMeInfoV2 mod (geometry-LOD proxy enumeration that works on 1.29).

How it works

• modded House reads the building's geometry LOD selections (GetLODByName(LOD.NAME_GEOMETRY).GetSelections()), finds those containing a proxy path, and builds position → proxy name maps (client-side).
• YAProxyActionBase resolves which proxy the cursor is on, and syncs the resolved name + world position to the server via ActionData.
• Detection uses no entities. (Spawning an invisible marker entity is only one option a consumer can use for persistent state, e.g. "sink is repaired for N days" — handled by the consuming mod, not here.)

Writing an action (consumer mods)

class ActionMySearch : YAProxyActionBase
{
    override string GetProxyKeywords() { return "fridge,lekarnicka"; } // substring match; "*" = any
    override float  GetDuration()      { return 3.0; }
    override string GetText()          { return "Search"; }

    // optional extra availability check (client)
    override bool YA_ExtraCondition(PlayerBase p, ActionTarget t, ItemBase i, string name, vector ws)
    { return !p.GetItemInHands(); }

    override void OnFinishProgressServer(ActionData ad)
    {
        string proxy = GetProxyName(ad);   // synced proxy name
        vector ws    = GetProxyWS(ad);     // synced world position
        // ... your effect ...
    }
}

Register it (required, or AddAction dereferences null):

modded class ActionConstructor { override void RegisterActions(TTypenameArray a){ super.RegisterActions(a); a.Insert(ActionMySearch); } }

Attach it where it should appear:

• empty-handed → modded PlayerBase.SetActions(out TInputActionMap m){ super...; AddAction(ActionMySearch, m); }
• tool/container in hands → modded Wrench / Bottle_Base .SetActions(){ super...; AddAction(ActionMySearch); }

For an item-in-hands action, override CreateConditionComponents() to use CCINonRuined instead of the default CCINotPresent.

Debug / discovery

YAProxyConstants.DEBUG (default true during bring-up) enables:

• per-house scan logs: [YAProxy] House 'Land_X' proxies built: map1=N map2=M
• an empty-handed "Proxy: <name>" action on any proxy that, on execute, dumps the resolved name, local vs world position, the full house proxy map, and the server-synced values.

Set DEBUG = false for production (and remove YAProxyDebug.c if desired).

Notes / limitations

• A building only scans if its script class is House. Many vanilla buildings aren't House by default; declare them class Land_X : House {} (see ZenProxyFramework's ScriptedBuildings.c for a curated list) as needed.
• Some proxies are missed by the LOD scan and need manual position overrides (also per-building) — a future addition if required.
