1. Mod Won't Load

These are problems where the mod does not appear, does not activate, or is rejected by the game at startup.

Sintoma	Causa	Correção
"Addon requires addon X" error at startup	Missing or incorrect requiredAddons[] entry	Add the exact CfgPatches class name of the dependency to your requiredAddons[]. Names are case-sensitive. See Capítulo 2.2.
Mod not visible in launcher	mod.cpp file is missing or has syntax errors	Create or fix mod.cpp in your mod root. It must contain name, author, and dir fields. See Capítulo 2.3.
"Config parse error" on startup	Sintaxe error in config.cpp	Check for missing semicolons after class closings (};), unclosed braces, or unbalanced quotes. Every class body ends with };, every property ends with ;.
No script log entries at all	CfgMods defs block points to wrong path	Verify that your config.cpp CfgMods entry has the correct dir and that the script defs file matches your folder structure. The engine silently ignores wrong paths.
Mod loads but nothing happens	Scripts compile but never execute	Check that your mod has an entry point: a modded class MissionServer or MissionGameplay, a registered module, or a plugin. Scripts do not run by themselves. See Capítulo 7.2.
"Cannot register cfg class X"	Duplicate CfgPatches class name	Another mod already uses that class name. Rename your CfgPatches class to something unique with your mod prefix.
Mod loads only in singleplayer	Server does not have the mod installed	Ensure the server's -mod= launch parameter includes your mod path, and the PBO is in the server's @YourMod/Addons/ folder.
"Addon X is not signed"	Server requires signed addons	Sign your PBOs with your private key and provide the .bikey to the server's keys/ folder. See Capítulo 4.6.

---

2. Script Errors

These appear in the script log as SCRIPT (E): or SCRIPT ERROR: lines.

Sintoma	Causa	Correção
Null pointer access	Accessing a variable that is null	Add a null check before using the variable: if (myVar) { myVar.DoSomething(); }. This is the most common runtime error.
Cannot convert type 'X' to type 'Y'	Direct cast between incompatible types	Use Class.CastTo() for safe downcasting: Class.CastTo(result, source);. Never assume a cast will succeed. See Capítulo 1.9.
Undefined variable 'X'	Typo, wrong scope, or wrong layer	Check spelling first. If the variable is a class from another file, ensure it is defined in the same or lower layer. 3_Game cannot see 4_World types. See Capítulo 2.1.
Método 'X' not found	Calling a method that does not exist on that class	Verify the method name and check the parent class. You may need to cast to a more specific type first. Check vanilla scripts at P:\DZ\scripts\ for the correct API.
Division by zero	Dividing by a variable that equals 0	Add a guard: if (divisor != 0) result = value / divisor;. This also applies to modulo (%) operations.
Redeclaration of variable 'X'	Same variable name declared in sibling else if blocks	Declare the variable once before the if/else chain, then assign inside each branch. See Capítulo 1.12.
Member already defined	Duplicate variable or method name in a class	Check for copy/paste errors. Each member name must be unique within a class hierarchy (including parent classes).
Cannot create instance of type 'X'	Trying to new an abstract class or an interface	Check that the class is not abstract (no proto methods without bodies). Instantiate a concrete subclass instead.
Stack overflow	Infinite recursion	A method calls itself without a base case, or a modded class override does not properly guard against re-entry. Add a depth check or fix the recursive call.
Index out of range	Array access with invalid index	Always check array.Count() or use array.IsValidIndex(idx) before accessing by index.
String conversion error	Using string.ToInt() or string.ToFloat() on non-numeric text	Validate string content before conversion. There is no try/catch, so you must guard manually.
Error: Serializer X mismatch	Read/write order does not match in serialization	Ensure OnStoreSave() and OnStoreLoad() write and read the same types in the same order, including version checks.
Sintaxe error with no clear message	Backslash \ or escaped quote \" in string literal	Enforce Script's CParser does not support \\ or \". Use forward slashes for paths ("my/path/file"). For quotes, use single-quote characters. See Capítulo 1.12.
JsonFileLoader returns null data	Assigning the return value of JsonLoadFile()	JsonLoadFile() returns void. Pre-allocate the object and pass it by reference: ref MyConfig cfg = new MyConfig(); JsonFileLoader<MyConfig>.JsonLoadFile(path, cfg);. See Capítulo 6.8.
Object.IsAlive() does not exist	Calling IsAlive() on base Object	IsAlive() is only on EntityAI. Cast first: EntityAI entity; if (Class.CastTo(entity, obj) && entity.IsAlive()) { ... }
No ternary operator support	Using condition ? a : b syntax	Enforce Script has no ternary operator. Use an if/else block instead. See Capítulo 1.12.
do...while loop error	Using do { } while(cond)	Enforce Script does not support do...while. Use a while loop with a break condition instead. See Capítulo 1.12.
Multiline method call fails	Splitting a single method call across lines incorrectly	Avoid splitting chained calls with comments or preprocessor directives between lines. Keep method call chains on one line or use intermediate variables.

---

3. RPC and Network Issues

Problemas with Remote Procedure Calls and client-server communication.

Sintoma	Causa	Correção
RPC sent but never received	Registration mismatch	Both sender and receiver must register the same RPC ID. Verify the ID matches exactly on both client and server. See Capítulo 6.9.
RPC received but data is corrupted	Read/write parameter mismatch	The sender's Write() calls and receiver's Read() calls must have the same types in the same order. A single mismatch corrupts all subsequent reads.
RPC crashes the server	Null entity target or wrong parameter types	Ensure the target entity exists on both sides. Never send null as the RPC target. Validate all read parameters before use.
Data not syncing to clients	Missing SetSynchDirty()	After changing any variable registered for synchronization, call SetSynchDirty() on the entity. Without it, the engine does not broadcast changes.
Works in singleplayer / listen server, fails on dedicated	Different code paths for listen vs. dedicated	On a listen server, both client and server run in the same process, hiding timing and null issues. Always test on a dedicated server. Check GetGame().IsServer() and GetGame().IsMultiplayer() guards.
RPC floods and server lag	Sending RPCs every frame or in tight loops	Throttle RPC calls with timers or accumulators. Batch multiple small updates into a single RPC. Use Net Sync Variávels for data that changes frequently.
Client receives RPC meant for all clients	Using RPCSingleParam with wrong target	Use null as the identity parameter to broadcast, or provide a specific PlayerIdentity to send to one client.
OnRPC() never called	Override is in the wrong class or layer	OnRPC() must be overridden on the entity that receives the RPC. If overriding on PlayerBase, ensure you call super.OnRPC() so other mods still work.
Net Sync Variávels not updating on client	Missing RegisterNetSyncVariável*() or wrong type	Register each variable in the constructor with the correct method (RegisterNetSyncVariávelInt, RegisterNetSyncVariávelFloat, RegisterNetSyncVariávelBool). Override OnVariávelsSynchronized() to react to changes on the client side.
RPC works for host but not other players	Using player object reference instead of identity	On dedicated servers, the host player is not special. Ensure you are using PlayerIdentity for targeting and not relying on local player references that only exist on the sender's machine.

---

4. UI Problemas

Issues with GUI layouts, widgets, menus, and input.

Sintoma	Causa	Correção
Layout loads but nothing is visible	Widget size is zero	Check hexactsize and vexactsize values. Both must be greater than zero. Do not use negative sizes. See Capítulo 3.3.
CreateWidgets() returns null	Layout file path is wrong or file is missing	Verify the .layout file path is correct (forward slashes, no typos). The engine returns null silently on bad paths, no error is logged.
Widgets exist but cannot be clicked	Another widget is covering the button	Check widget priority (z-order). Higher priority widgets render on top and capture input first. Also check that the button has ButtonWidget as its ScriptClass or is a ButtonWidget type.
Game input is stuck / cannot move after closing UI	ChangeGameFocus() calls are imbalanced	Every GetGame().GetInput().ChangeGameFocus(1) must be paired with ChangeGameFocus(-1). Track your focus changes and ensure cleanup happens even if the UI is force-closed.
Text shows #STR_some_key literally	Stringtable entry is missing or file is not loaded	Add the key to your stringtable.csv. Check that the CSV is in your mod root and has the correct Language,Key,Original header format. See Capítulo 5.2.
Mouse cursor does not appear	ShowUICursor() not called	Call GetGame().GetUIManager().ShowUICursor(true) when opening your UI. Call it with false when closing.
UI flickers or renders behind game world	Layout is not attached to correct parent widget	Attach your layout to a proper parent. For fullscreen overlays, use GetGame().GetWorkspace() as the parent.
ScrollWidget content does not scroll	Content is not inside a WrapSpacer or child widget	ScrollWidget needs a single child (usually a WrapSpacer or FrameWidget) that is larger than the scroll area. Put your content widgets inside that child. See Capítulo 3.3.
Image or icon not showing	Path uses backslashes or wrong extension	Use forward slashes in image paths. Verify the file exists and is in a recognized format (.paa, .edds). Use ImageWidget for images, not TextWidget.
Slider does not respond to input	Missing script handler or wrong widget type	Ensure the slider widget has a ScriptClass assigned and that your handler processes OnChange events. Initialize the slider range in script.
UI looks different at other resolutions	Using hardcoded pixel values	Use proportional sizing (halign, valign, hfill, vfill) instead of fixed pixel values. Test at multiple resolutions. See Capítulo 3.3.

---

5. Build and PBO Issues

Problemas with packing, binarizing, and deploying mods.

Sintoma	Causa	Correção
"Include file not found" during binarize	Config references a file that does not exist	Check that all #include paths in model configs and rvmats are correct. Ensure the P: drive is mounted and source files are accessible.
PBO builds successfully but mod crashes on load	config.cpp binarization error	Try building with binarization disabled to isolate the issue. If it works unbinarized, the problem is in a config that the binarizer rejects silently.
"Assinatura check failed" on server connect	PBO is unsigned or signed with wrong key	Re-sign the PBO with your private key using DSSignFile. Ensure the server has the matching .bikey in its keys/ folder.
File patching changes not taking effect	Not using the diagnostic executable	File patching only works with DayZDiag_x64.exe, not the retail DayZ_x64.exe. Launch with -filePatching parameter.
"Prefix mismatch" warning	PBO prefix does not match config.cpp	Ensure the $PBOPREFIX$ file content matches the addon prefix defined in your config.cpp CfgPatches.
Addon Builder fails silently	Path contains special characters or spaces	Move your project to a path without spaces or special characters. Use short folder names.
Binarized model looks wrong in-game	LOD or geometry issues in P3D	Check model LODs in Object Builder. Ensure the Fire Geometry and View Geometry LODs are correct. Rebuild the model.
Old version of mod loads despite changes	Cached PBO or workshop version overriding	Delete the old PBO. Check that the game is not loading a cached workshop version. Verify the -mod= path points to your development folder, not the workshop folder.
Addon Builder reports "no entry" warnings	Config references a property that does not exist	These warnings are usually non-fatal. Check that all CfgVehicles base classes exist. Missing entries in inherited configs cause cascading warnings.
PBO packing includes unwanted files	No .pboignore or filter set	Addon Builder packs everything in the source folder. Use a .pboignore file or explicitly exclude file types (.psd, .blend, .bak) in the builder settings.

---

6. Performance Issues

Server or client FPS drops, memory problems, and slow operations.

Sintoma	Causa	Correção
Low server FPS (below 20)	Heavy processing in OnUpdate() or per-frame methods	Use a delta-time accumulator to throttle work: only execute logic every N seconds. Move expensive operations to timers or scheduled callbacks. See Capítulo 7.7.
Memory grows over time (memory leak)	ref reference cycles preventing garbage collection	When two objects hold ref references to each other, neither is ever freed. Make one side a raw (non-ref) reference. Break cycles in cleanup methods. See Capítulo 1.8.
Slow server startup	Heavy initialization in OnInit	Defer non-critical initialization with GetGame().GetCallQueue(CALL_CATEGORY_SYSTEM).CallLater(). Load configs lazily on first use instead of all at startup.
Client FPS drops near specific objects	Complex model with too many polygons or bad LODs	Add proper LOD levels to your model. The engine uses LODs to reduce poly count at distance. Ensure LOD transitions are smooth.
Stutter every few seconds	Periodic garbage collection spikes	Reduce object churn. Reuse objects via pooling instead of constantly creating and destroying them. Pre-allocate arrays.
Network lag spikes	Too many RPCs or large RPC payloads	Batch small updates into fewer RPCs. Use Net Sync Variávels for frequently changing values. Compress data where possible.
Log file growing very large	Excessive Print() or debug logging	Remove or guard debug Print() calls behind #ifdef DEVELOPER or a debug flag. Large log files can slow disk I/O.
High entity count causing server lag	Too many spawned entities in the world	Reduce nominal values in types.xml. Clean up dynamic objects with lifetime management. Limit AI spawn density.

---

7. Item, Vehicle, and Entity Issues

Problemas with custom items, vehicles, and world entities.

Sintoma	Causa	Correção
Item will not spawn (admin tools say "cannot create")	scope=0 in config or missing from types.xml	Set scope=2 in your item's CfgVehicles config for items that should be spawnable. Add an entry to your server's types.xml if the item should appear in loot.
Item spawns but is invisible	Model path (.p3d) is wrong or missing	Check the model path in your CfgVehicles class. Use forward slashes. Verify the .p3d file exists and is packed in your PBO.
Item has no inventory icon	Missing or wrong inventorySlot or icon config	Define the picture path in your config pointing to a valid .paa or .edds icon file. Check rotationFlags for correct icon orientation.
Vehicle spawns but will not drive	Missing engine, wheels, or parts	Ensure all required parts are attached. Use OnDebugSpawn() to spawn a fully assembled vehicle for testing. Check that simulation type is correct in config.
Item cannot be picked up	Incorrect geometry or wrong inventorySlot	Verify the item has proper Fire Geometry in the model. Check that the itemSize[] is set correctly and the item fits in available inventory slots.
Entity immediately deleted after spawn	lifetime is zero in types.xml or scope issue	Set appropriate lifetime value in types.xml. Ensure scope=2 in config. Check server cleanup settings in globals.xml.
Custom animal/zombie does not move	AI config missing or broken	Verify AIAgentType in config. Check that the entity has proper NavMesh-compatible geometry. Test with vanilla AI configs first.
Attachments do not snap to item	Wrong inventorySlot names	Attachment slot names must match exactly between the parent item's attachments[] and the child item's inventorySlot[]. Names are case-sensitive.
Item damage zones not working	DamageSystem config mismatch with model	Each DamageZone name must match a named selection in the model's Fire Geometry LOD. Check with Object Builder. See Capítulo 6.1.
Custom sound does not play	Sound shader or config path wrong	Verify the sound shader class name in CfgSoundShaders and CfgSoundSets. Check that the .ogg file path is correct and the file is packed in the PBO.
Item has wrong weight or size	weight and itemSize[] config values	weight is in grams (integer). itemSize[] defines the inventory grid slots as {width, height}. Check parent class values if inheriting.
Crafting recipe not appearing	Recipe config or condition wrong	Check CfgRecipes registration. Verify both ingredient items have correct canBeSplit, isMeleeWeapon, or other required properties. Test with vanilla recipe configs as reference.

---

8. Config and Types Issues

Problemas with config.cpp, types.xml, and other configuration files.

Sintoma	Causa	Correção
Config values not taking effect	Using binarized config but editing source	Rebuild your PBO after config changes. If using file patching, ensure DayZDiag_x64.exe and -filePatching are active.
types.xml changes ignored	Editing the wrong types.xml file	The server loads types from mpmissions/your_mission/db/types.xml. Editing a types file elsewhere has no effect. Check the server's active mission folder.
"Error loading types" on server start	XML syntax error in types.xml	Validate your XML. Common issues: unclosed tags, missing quotes on attribute values, or & instead of &. Use an XML validator.
Items spawn with wrong quantities	quantmin/quantmax values incorrect	Valors are percentages (0-100) in types.xml, not absolute counts. -1 means "use default".
Loot table not spawning items	nominal is 0 or missing category/usage/tag	Set nominal above 0. Add at least one <usage> and <category> tag so the Central Economy knows where to spawn items.
JSON config file not loading	Malformed JSON or wrong path	Validate JSON syntax (no trailing commas, proper quoting). Use $profile: prefix for server profile paths. Check that the file exists with FileExist().
cfgGameplay.json changes ignored	File not enabled or wrong location	Place the file in the mission folder. Set enableCustomGameplay to 1 in serverDZ.cfg. Restart the server (not just reload).
Class inheritance not working in config	baseClass misspelled or not loaded	The parent class must exist in the same or earlier addon. Check that requiredAddons[] includes the addon defining the parent class.

---

9. Persistence Issues

Problemas with data saving and loading across server restarts.

Sintoma	Causa	Correção
Player data lost on restart	Not saving to $profile: directory	Use JsonFileLoader<T>.JsonSaveFile() with a $profile: path. Save on player disconnect (PlayerDisconnected) and periodically during gameplay.
Saved file is empty or corrupt	Crash during write, or serialization error	Write to a temporary file first, then rename to the final path. Validate data before saving. Always handle FileExist() checks on load.
OnStoreSave/OnStoreLoad mismatch	Version changed but no migration	Always write a version number first. On load, read the version and handle old formats: if (version < CURRENT) { /* read old format */ }.
Items disappear from storage	lifetime expired in types.xml	Increase lifetime for persistent items. Padrão is often too short for base-building containers. Check globals.xml cleanupLifetimeRuin value.
Custom variables reset on relog	Variávels not synced or stored	Register variables for network sync with RegisterNetSyncVariável*(). For persistence, save/load in OnStoreSave()/OnStoreLoad().

---

10. Decision Flowcharts

Step-by-step diagnostic processes for common "it doesn't work" situations.

"My mod doesn't work at all"

1. Check the script log for SCRIPT (E) errors. Correção the first error you find. (Section 2)
2. Is the mod listed in the launcher? If not, check that mod.cpp exists and is valid. (Section 1)
3. Does the log mention your CfgPatches class? If not, check config.cpp syntax, requiredAddons[], and the -mod= launch parameter.
4. Do scripts compile? Look for compile errors in the RPT. Correção any syntax errors. (Section 2)
5. Is there an entry point? You need a modded class MissionServer/MissionGameplay, a registered module, or a plugin. Scripts without an entry point never run.
6. Still nothing? Add Print("MY_MOD: Init reached"); at your entry point to confirm execution.

"Works offline but not on a dedicated server"

1. Is the mod installed on the server? Check that -mod= includes your mod path and the PBO is in @YourMod/Addons/.
2. Client-only code on server? GetGame().GetPlayer() returns null during server init. Add GetGame().IsServer() / GetGame().IsClient() guards.
3. RPCs working? Add Print() on both send and receive sides. Check that RPC IDs match and target entity exists on both sides. (Section 3)
4. Data syncing? Verify SetSynchDirty() is called after changes. Check read/write parameter order matches.
5. Timing issues? Listen servers hide race conditions because client and server share a process. Dedicated servers expose these. Add null checks and readiness guards.

"My UI is broken"

1. Does CreateWidgets() return null? The layout path is wrong or the file is missing. Check forward slashes, verify the .layout is packed in the PBO.
2. Widgets exist but invisible? Check sizes (must be > 0, no negative values). Check Show(true) is called. Check text/widget alpha is not 0.
3. Visible but not clickable? Check widget priority (z-order). Verify ScriptClass is assigned. Confirm the handler is set.
4. Input stuck after closing UI? ChangeGameFocus() calls are imbalanced. Every ChangeGameFocus(1) needs a matching ChangeGameFocus(-1). Check cleanup runs even on force-close.

12. Log File Locations

Knowing where to look is half the battle.

Client Logs

Log	Location	Contains
Script log	%localappdata%\DayZ\ (most recent .RPT file)	Script errors, warnings, Print() output
Crash dumps	%localappdata%\DayZ\ (.mdmp files)	Crash analysis data
Workbench log	Workbench IDE output panel	Compile errors during development

Server Logs

Log	Location	Contains
Script log	<server_root>\profiles\ (most recent .RPT file)	Script errors, server-side Print()
Admin log	<server_root>\profiles\ (.ADM file)	Player connections, kills, chat
Crash dumps	<server_root>\profiles\ (.mdmp files)	Server crash data
Custom logs	<server_root>\profiles\	Any logs written with FileHandle

Reading Logs Effectively

• Search for SCRIPT (E) to find script errors
• Search for SCRIPT ERROR to find fatal script problems
• Search for your mod name or class names to filter relevant entries
• Errors often cascade -- fix the first error in the log, not the last
• Timestamp each log read: the most recent .RPT file has the latest session
