NWNX

Core Functionality

The core of NWNX:EE that does all the things.

Environment Variables

Variable Name Value Default Notes
NWNX_CORE_SKIP 0-1 0 Set whether to load NWNX or not.
NWNX_CORE_LOAD_PATH string Unset The directory from where plugins are loaded. Defaults to where NWNX_Core is located.
NWNX_CORE_SKIP_ALL 0-1 0 Changes the default plugin load state from 'load all' to 'skip all'. Use NWNX_{PLUGIN}_SKIP=n to enable specific plugins in this case.
NWNX_CORE_LOG_LEVEL 0-7 0 Sets the default log level. 6 is a good level for live servers. 7 includes debug messages which can be helpful if you're having issues.
NWNX_CORE_LOAD_EXPERIMENTAL_PLUGIN 0-1 0 Allows loading of NWNX_Experimental, use at your own risk.
NWNX_CORE_LOCALE string Unset Set the locale NWNX will use when encoding. Supported are cp1250, cp1251, cp1252 (default). Can also use two letter country codes (e.g. "ru")
NWNX_CORE_CRASH_ON_ASSERT_FAILURE 0-1 0 Sets whether an ASSERT failure hard crashes the server.
NWNX_CORE_SHUTDOWN_SCRIPT string Unset Sets which NWScript to run when the module shuts down.
NWNX_CORE_ALLOW_NWNX_FUNCTIONS_IN_EXECUTE_SCRIPT_CHUNK 0-1 0 When enabled, allows the ExecuteScriptChunk() function to call NWScript NWNX functions.
NWNX_CORE_NWNX_RESOURCE_DIRECTORY_PATH string UserDirectory/nwnx The path of the /nwnx resource directory
NWNX_CORE_CUSTOM_RESMAN_DEFINITION string Unset A path to a file with custom resource directory aliases, see below for more info
NWNX_CORE_NWNX_RESOURCE_DIRECTORY_PRIORITY int 70000000 Sets the resman priority of the UserDirectory/nwnx folder.
NWNX_CORE_LOG_TIMESTAMP 0-1 1 Set whether to show timestamp in logs printed by NWNX.
NWNX_CORE_LOG_DATE 0-1 0 Set whether to show date(Y-M-D) in logs printed by NWNX. Timestamps must be enabled.
NWNX_CORE_LOG_PLUGIN 0-1 1 Set whether to show plugin name in logs printed by NWNX.
NWNX_CORE_LOG_SOURCE 0-1 1 Set whether to show source code location in logs printed by NWNX.
NWNX_CORE_LOG_COLOR 0-1 1 Set whether to show logs printed by NWNX in color (only when printing to a TTY).
NWNX_CORE_LOG_FORCE_COLOR 0-1 0 Sets whether to force color output.
NWNX_CORE_LOG_FILE_PATH string Unset Sets the secondary (in addition to stdout) log file.
NWNX_CORE_HARD_EXIT 0-1 0 If set, NWNX will hard kill the process after it unloads.
NWNX_CORE_BASE_GAME_CRASH_HANDLER 0-1 0 Sets whether to also call the base game handler in case of crash.

Console Commands

Command Description
runscript <script name> Executes the given nwscript. Example: runscript dm_killallplayers
eval <script chunk> Executes the given nwscript chunk. Example: eval ApplyEffectToObject(DURATION_TYPE_INSTANT, EffectDeath(), GetFirstPC());
evalx <script chunk> Executes the given nwscript chunk, this command already includes all nwnx headers available in the module. Example: evalx NWNX_Administration_ShutdownServer();
loglevel <plugin> [<loglevel>] Sets the log level of the given plugin. <plugin> should not have the NWNX_ prefix. Example: loglevel Events 7
logformat [timestamp\|notimestamp] [plugin\|noplugin] [source\|nosource] [color\|nocolor] [force\|noforce] Control the output format of logs. Example: logformat color timestamp noplugin nosource

Custom Resman Definition File

A file that lets you specify additional resource directories that act the same as the /development and /nwnx folders.

Each line in the file must contain the following: ALIASNAME /full/path/to/folder <priority>

Example:

TEST /home/nwnx/test 70000001
STUFF /home/nwnx/stuff 70000002

Plugin Management

Environment Variable Configuration

Configuration of NWNX plugins are controlled by environment variables exported prior to starting the nwserver binary. Typical usage would be in the script used to start the server.

Basic control of the plugin includes enabling/disabling the plugin and setting the logging level of the plugin. The following format is used for all plugins:

  • NWNX_<x>_LOG_LEVEL
  • NWNX_<x>_SKIP

Plugin Loading

Inclusion or exclusion of the plugin at server startup time is contolled by the environment variable NWNX_<x>_SKIP where <x> is the plugin name (all caps).

  • Setting this to N will load the plugin (i.e. it will not be skipped) at startup (default).
  • Setting this to Y will cause the plugin to BE SKIPPED at startup.

Example

# Load the sql plugin at startup
export NWNX_SQL_SKIP=N

Plugin Log Level

The default plugin log level is the same as the overall Core logging level.

It can be changed, however, by assinging a value to NWNX_<x>_LOG_LEVEL (where <x> is the plugin name in all caps) in the same manner as the Core logging level. See the Core documentation for a description of available logging levels.

Example

# Set the sql plugin to warning and above (warning, error, and fatal only)
export NWNX_SQL_LOG_LEVEL=4

Core Functions For Plugin Developers

The core functions in nwnx.nss should be called by NWNX plugin developers, who should expose their own, more friendly headers.

Sample

This following function would wrap a call which passes three parameters, receives three back, and constructs a vector from the result.

vector GetVectorFromCoords(float x, float y, float z)
{
string pluginName = "NWNX_TestPlugin";
string funcName = "GiveMeBackTheSameValues";
// Note the inverse argument push order.
// C++-side, arguments will be consumed from left to right.
// This calls the function, which will prepare the return values.
NWNX_CallFunction(pluginName, funcName);
// C++-side pushes the return values in reverse order so we can consume them naturally here.
return vector(_x, _y, _z);
}
