This callback gets called when the server finishes loading and initializing plugins. This is the perfect occasion for a plugin to query other plugins through cPluginManager:GetPlugin() and possibly start communicating with them using the cPlugin:Call() function.

Callback function

The default name for the callback function is OnPluginsLoaded. It has the following signature:

function MyOnPluginsLoaded()

Parameters:

The return value is ignored, all registered callbacks are called.

Code examples

Registering the callback

cPluginManager:AddHook(cPluginManager.HOOK_PLUGINS_LOADED, MyOnPluginsLoaded);

CoreMessaging

This example shows how to implement the CoreMessaging functionality - messages to players will be sent through the Core plugin, formatted by that plugin. As a fallback for when the Core plugin is not present, the messages are sent directly by this code, unformatted.

-- These are the fallback functions used when the Core is not present:
local function SendMessageFallback(a_Player, a_Message)
	a_Player:SendMessage(a_Message);
end

local function SendMessageSuccessFallback(a_Player, a_Message)
	a_Player:SendMessage(a_Message);
end

local function SendMessageFailureFallback(a_Player, a_Message)
	a_Player:SendMessage(a_Message);
end

-- These three "variables" will hold the actual functions to call.
-- By default they are initialized to the Fallback variants,
-- but will be redirected to Core when all plugins load
SendMessage        = SendMessageFallback;
SendMessageSuccess = SendMessageSuccessFallback;
SendMessageFailure = SendMessageFailureFallback;

-- The callback tries to connect to the Core
-- If successful, overwrites the three functions with Core ones
local function OnPluginsLoaded()
	local CorePlugin = cPluginManager:Get():GetPlugin("Core");
	if (CorePlugin == nil) then
		-- The Core is not loaded, keep the Fallback functions
		return;
	end
	
	-- Overwrite the three functions with Core functionality:
	SendMessage = function(a_Player, a_Message)
		CorePlugin:Call("SendMessage", a_Player, a_Message);
	end
	SendMessageSuccess = function(a_Player, a_Message)
		CorePlugin:Call("SendMessageSuccess", a_Player, a_Message);
	end
	SendMessageFailure = function(a_Player, a_Message)
		CorePlugin:Call("SendMessageFailure", a_Player, a_Message);
	end
end

-- Global scope, register the callback:
cPluginManager.AddHook(cPluginManager.HOOK_PLUGINS_LOADED, CoreMessagingPluginsLoaded);


-- Usage, anywhere else in the plugin:
SendMessageFailure(
	a_Player,
	"Cannot teleport to player, the destination player " .. PlayerName .. " was not found"
);
