--- **AceAddon-3.0** provides a template for creating addon objects. |
--- '''AceAddon-3.0''' provides a template for creating addon objects. |
-- It'll provide you with a set of callback functions that allow you to simplify the loading |
-- process of your addon.\\ |
-- Callbacks provided are:\\ |
-- * **OnInitialize**, which is called directly after the addon is fully loaded. |
-- * **OnEnable** which gets called during the PLAYER_LOGIN event, when most of the data provided by the game is already present. |
-- * **OnDisable**, which is only called when your addon is manually being disabled. |
-- @usage |
-- -- A small (but complete) addon, that doesn't do anything, |
-- -- but shows usage of the callbacks. |
-- local MyAddon = LibStub("AceAddon-3.0"):NewAddon("MyAddon") |
-- |
-- function MyAddon:OnInitialize() |
-- -- do init tasks here, like loading the Saved Variables, |
-- -- or setting up slash commands. |
-- end |
-- |
-- function MyAddon:OnEnable() |
-- -- Do more initialization here, that really enables the use of your addon. |
-- -- Register Events, Hook functions, Create Frames, Get information from |
-- -- the game that wasn't available in OnInitialize |
-- end |
-- |
-- function MyAddon:OnDisable() |
-- -- Unhook, Unregister Events, Hide frames that you created. |
-- -- You would probably only use an OnDisable if you want to |
-- -- build a "standby" mode, or be able to toggle modules on/off. |
-- end |
-- process of your addon. Callbacks provided are:<br> |
-- - '''OnInitialize''', which is called directly after the addon is fully loaded.<br> |
-- - '''OnEnable''' which gets called during the PLAYER_LOGIN event, when most of the data provided by the game is already present.<br> |
-- - '''OnDisable''', which is only called when your addon is manually being disabled.<br> |
