DayZ Development

Dynamic documentation orchestrator for DayZ mod development. Supports vanilla Enforce Script, Community Framework (CF), and DayZ Expansion. Target version: DayZ 1.28+ (v1.28.161464)

Philosophy

1. Fetch, don't memorize - Always get latest from authoritative sources
2. Framework-aware thinking - Detect vanilla vs CF vs Expansion, adapt patterns
3. Enforce Script correctness - DayZ uses Enforce Script (C-like), NOT C#/C++/Lua
4. Server-side validation - Never trust client-side data
5. Null-safe always - Every Cast<>, GetInventory(), GetIdentity() must be null-checked

CRITICAL: No Hallucination Policy

NEVER invent or guess Enforce Script classes, methods, config tokens, or parameters.

Rules:

1. If unsure about a class/method -> MUST fetch from DayZ Scripts API or Script Diff repo
2. If unsure about config.cpp tokens -> MUST fetch from BI wiki or DayZ Central Economy repo
3. If a class doesn't exist -> Tell user honestly, suggest alternatives
4. If parameters unknown -> Fetch documentation, don't guess
5. NEVER use C#/C++ syntax -> Enforce Script looks like C but has key differences

Before writing any class or method call:

• Is this a real DayZ class? -> Verify at dayz-scripts.yadz.app or DayZ-Script-Diff
• Is this the correct method signature? -> Check parameter types and order
• Does this work on server/client/both? -> Check script module (3_Game/4_World/5_Mission)
• Am I null-checking accessors? -> Cast<>, GetInventory(), GetIdentity(), GetPlayer()

When you don't know:

"I'm not 100% certain about this class/method. Let me fetch the documentation..."
[Use WebFetch to get accurate info]

Verification Sources:

Example - WRONG:

// DON'T: Using C# syntax or inventing methods
player.GetComponent<Inventory>().AddItem("AK74");  // NOT Enforce Script!

Example - RIGHT:

// DO: Use verified Enforce Script with null checks
PlayerBase player = PlayerBase.Cast(GetGame().GetPlayer());
if (player)
{
    EntityAI item = player.GetInventory().CreateInInventory("AKM");
    if (item)
    {
        // item created successfully
    }
}

Mod Framework Auto-Detection

When starting a task, detect what frameworks the mod uses:

Check config.cpp dependencies

// Vanilla only
requiredAddons[] = {"DZ_Data"};

// Community Framework
requiredAddons[] = {"DZ_Data", "JM_CF_Scripts"};

// Expansion
requiredAddons[] = {"DZ_Data", "JM_CF_Scripts", "DayZExpansion_Core"};

Check script imports

// CF detection
GetRPCManager()     // Uses CF RPC system
CF_ModuleWorld      // Uses CF Module system

// Expansion detection
ExpansionMarketModule       // Uses Expansion Market
ExpansionQuestModule        // Uses Expansion Quests
eAIBase                     // Uses Expansion AI

Check mod.cpp / meta.cpp

// CF dependency
dependency[] = {"Community Framework"};

// Expansion dependency
dependency[] = {"DayZ Expansion Core", "DayZ Expansion Scripts"};

DayZ-Specific Patterns

Modded Class Injection (The DayZ Way)

modded class PlayerBase
{
    override void SetActions(out TInputActionMap InputActionMap)
    {
        super.SetActions(InputActionMap);
        AddAction(MyCustomAction, InputActionMap);
    }
}

RPC Communication (Vanilla)

// Server -> Client
ScriptRPC rpc = new ScriptRPC();
rpc.Write(someData);
rpc.Send(player, ERPCs.RPC_USER_ACTION_MESSAGE, true, player.GetIdentity());

// Client handler
void OnRPC(PlayerIdentity sender, Object target, int rpc_type, ParamsReadContext ctx)
{
    if (rpc_type == ERPCs.RPC_USER_ACTION_MESSAGE)
    {
        ctx.Read(someData);
    }
}

RPC Communication (CF)

// Register
GetRPCManager().AddRPC("MyMod", "MyRPCHandler", this, SingeplayerExecutionType.Both);

// Send
GetRPCManager().SendRPC("MyMod", "MyRPCHandler", new Param1<string>("data"), true, null);

// Handler
void MyRPCHandler(CallType type, ParamsReadContext ctx, PlayerIdentity sender, Object target)
{
    Param1<string> data;
    if (!ctx.Read(data)) return;
    // process data.param1
}

Player Lifecycle Events

OnInit -> InvokeOnConnect -> OnClientReadyEvent -> OnClientDisconnectedEvent -> MissionFinish

Net Sync Variables

class MyEntity extends ItemBase
{
    int m_MyValue;

    void MyEntity()
    {
        RegisterNetSyncVariableInt("m_MyValue", 0, 100);
    }

    void SetMyValue(int val)
    {
        m_MyValue = val;
        SetSynchDirty();
    }

    override void OnVariablesSynchronized()
    {
        super.OnVariablesSynchronized();
        // m_MyValue is now updated on client
    }
}
