Required contents of your mod

In order to make a compatible mod there are certain requirements:

  1. Your mod has to comply with GPL v3 license and if you provide your mod publicly, the code has to be shared as per the license.
  2. Your mod has to be a unique package as per Torque 3D Standards.
  3. Your mod’s main entry point has to be a file named “mod.cs” as per the example below.
  4. In your mod.cs file, you have to register register at least one function to the LiFx hook “$LiFx::hooks::mods”. (with 3.0.0 this will be deprecated)
  5. Your package must provide a setup function. (mandatory from 3.0.0)
  6. Your package should provide a “version” function, specifying the version of your mod.

Hooks

Hook array Parameters Description
$LiFx::hooks::onStartCallbacks %this Executes when onStart is called by the server code and should be your main entry point for your mod to execute and load configuration.
$LiFx::hooks::onConnectRequestCallbacks %this, %gameConnection, %netaddress, %name Calls a function when a user is attempting to join
$LiFx::hooks::onPostConnectRoutineCallbacks %this, %gameConnection, %netaddress, %name  
$LiFx::hooks::onPreConnectRequestCallbacks %this, %gameConnection, %netaddress, %name  
$LiFx::hooks::onPostInitCallbacks %this Executes when onInit has ran and is where you need to register BasilMod pack commands to ensure that BasilMod syncs your server files to the client
$LiFx::hooks::onInitServerCallbacks %this Executes after DB changes and initial load of network
$LiFx::hooks::onInitServerDBChangesCallbacks %this Registering a function on this hook will execute your db calls just after dbi is initialized and before the server loads information from the database.
$LiFx::hooks::onSpawnCallbacks %this, %client Will execute your registered function every time a player spawns
$LiFx::hooks::onConnectCallbacks %this, %client Will execute one time per connecting client
$LiFx::hooks::onDisconnectCallbacks %this, %client Will execute one time per disconnecting client
$LiFx::hooks::onJHStartCallbacks %this Will execute registered function on JH Start event
$LiFx::hooks::onJHEndCallbacks %this Will execute registered function on JH End event
$LiFx::hooks::onDeathCallbacks %this, %CharID, %isKnockout, %Tombstone Executes on death event
$LiFx::hooks::onKillCallbacks %this, %CharID, %KillerID, %isKnockout, %Tombstone Executes on kill event (reverse objects of onDeath)
$LiFx::hooks::onSuicideCallbacks %this, %CharacterID, %isKnockout, %Tombstone Executed in case of a suicide
$LiFx::hooks::onTick %this Call a mod function every 5 seconds
$LiFx::hooks::onServerCreatedCallbacks - Is called when the ServerCreated event is done
$LiFx::hooks::onDestroyServerCallbacks - Is called when the DestroyServer event is done
$LiFx::hooks::onStartSwimCallbacks - Is called when someone starts swimming
$LiFx::hooks::onStopSwimCallbacks - Is called when someone stops swimming

Example

An example of server framework compatible mod.
Each server mod has to be named mod.cs for the framework to find it and execute it.

You can also use the public example starting point which you can find on in the public repository.
