Awards

Adds awards/achievements to Minetest (plus a very good API).

Majority of awards are back ported from Calinou's old fork in Carbone, under same license.

API

Registering Awards

awards.register_award("mymod:myaward", {
	description = "The title of the award",

	-- Optional:

	requires = { "amod:an_award" }, -- don't show this award or allow it to be unlocked
									-- until required awards are unlocked

	sound = {}, -- SimpleSoundSpec or false to play no sound
	            -- if not provided, uses default sound
	image = "icon_image.png", -- uses default icon otherwise
	background = "background_image.png", -- uses default background otherwise

	trigger = { -- is only unlocked by direct calls to awards.unlock() otherwise
		type = "trigger_type",
		-- see specific docs on the trigger to see what else goes here
	},
	
	-- Callback. award_def is this table (plus some additional methods/members added by register_award)
	on_unlock = function(name, award_def) end,
})

Registering Trigger Types

local trigger = awards.register_trigger(name, {
	type = "", -- type of trigger, defaults to custom

	progress = "%2/%2"
	auto_description = { "Mine: @2", "Mine: @1×@2" },

	on_register = function(self, def) end,

	-- "counted_key" only, when no key is given (ie: a total)
	auto_description_total = { "Mine @1 block.", "Mine @1 blocks." },

	-- "counted_key" only, get key for particular award - return nil for a total
	get_key = function(self, def)
		return minetest.registered_aliases[def.trigger.node] or def.trigger.node
	end,
})

Types:

"custom" requires you handle the calling of awards.unlock() yourself. You also need to implement on_register() yourself.
"counted" stores a single counter for each player which is incremented by calling trigger:notify(player). Good for homogenous actions like number of chat messages, joins, and the like.
"counted_key" stores a table of counters each indexed by a key. There is also a total field (__total) which stores the sum of all counters. A counter is incremented by calling trigger:notify(player, key). This is good for things like placing nodes or crafting items, where the key will be the item or node name.

Helper Functions

awards.register_on_unlock(func(name, def))
- name is the player name
- def is the award def.
- return true to cancel HUD
awards.unlock(name, award)
- gives an award to a player
- name is the player name

Included in the Mod

The API, above, allows you to register awards and triggers (things that look for events and unlock awards, they need to be registered in order to get details from award_def.trigger).

However, all awards and triggers are separate from the API. They can be found in init.lua and triggers.lua
