The System Node $CHARACTERSYSTEM handles Event callbacks related to a character on the client from the C++ engine. The callbacks primarily deal with very low level concepts such as introduction/removal of the HBNode representing a character, (un)assignment of control of the character by the server, changes in the _CharacterAppearance node's name field (used for the floating GUI Nametags), and reception of a character outfit handle (used in Character selection systems to display a visualization of a character prior to selection and exiting of the CSS.

What problem(s) does this solve?


$CHARACTERSYSTEM is a client-only system node

The $CHARACTERSYSTEM system node exists only on the client at this time as it handles client-side callbacks.


Adding game-specific functionality

As a required class/script, it is not permissible to make changes to the _characterSystemClassMethods script. Instead, extension/overriding the script is accomplished by the creation of a game-specific class (and class methods script) that is GLOMmed onto the CHARACTERSYSTEM prototype.

Create a game-specific class

Using the DOM Editor create a new (server|client) class. Our recommendation is that you use a class name that incorporates the _characterSystem as a suffix to the name (ex. HJ_characterSystem), this makes it easier to locate the pair of classes (the required script prefixed in _characterSystem and your game-specific class).

Once you have created the game-specific class, create a new client class methods script for that class.

Adding a game-specific class

Adding your game-specific class to the CHARACTERSYSTEM prototype is achieved using the System Node Configuration GUI or the CLI server command \mpac or client |mpac in the Console Panel. The System Node Configuration GUI is the preferred method because it handles the communication to update any instantiations of a system node to reflect the changes you have made.

Using the System Node Configuration GUI


Opening the System Node Configuration GUI requires you to access the hidden Utilities Interface toolbox, located in the top left corner of the render window with ctrl-shift-click (or press F5), which will open the Interface. On the Tools tab within the menu, is an option to open the System Nodes Configuration GUI.

Using the CLI

It is important to recognize that modification of the prototype from which a system node is instantiated will not update any instantiations that have already been made in various local GOMs. That means your changes will not take effect until the area (in the case of server system nodes) restarts, or the client (in the case of client system nodes), restarts.

Adding a class to a prototype is done via the CLI command Modify Prototype Add Class(MPAC).

Server: \mpac CHARACTERSYSTEM, hj_characterSystem;
Client: |mpac CHARACTERSYSTEM, hj_characterSystem;
