# API
## Registering Awards
# Introduction
## Awards and Triggers
An award is a single unlockable unit, registered like so:
```lua
awards.register_award("mymod:myaward", {
description = "The title of the award",
-- Optional:
difficulty = 1.0, -- Difficulty multipler
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,
awards.register_award("mymod:award", {
description = "My Example Award",
})
```
If the award is counted, ie: there's a trigger.target property, then the difficulty
multipler is timesd by target to get the overal difficulty. If the award isn't a
counted type then the difficulty multiplier is used as the overal difficulty.
Award difficulty affects how awards are sorted in a list - more difficult awards
are further down the list.
Awards are unlocked either using `awards.unlock()` or by a trigger being
fullfilled. A trigger is a condition which unlocks an award. Triggers are
registered at the same time as an award is registered:
```lua
awards.register_award("mymod:award", {
description = "My Example Award",
trigger = {
type = "dig",
node = "default:stone",
target = 10,
},
})
```
The above trigger type is an example of a counted_key trigger:
rather than a single counter there's a counter per key - in this
case the key is the value of the `node` field. If you leave out
the key in a `counted_key` trigger, then the total will be used
instead. For example, here is an award which unlocks after you've
placed 10 nodes of any type:
```lua
awards.register_award("mymod:award", {
description = "Place 10 nodes!",
trigger = {
type = "place",
target = 10,
},
})
```
You can also register an *Unlock Function*, which can return the name of an
award to unlock it:
```lua
awards.register_award("mymod:award", {
title = "Lava Miner",
description = "Mine any block while being very close to lava.",
})
awards.register_on_dig(function(player, data)
local pos = player:get_pos()
if pos and (minetest.find_node_near(pos, 1, "default:lava_source") or
minetest.find_node_near(pos, 1, "default:lava_flowing")) then
return "mymod:award"
end
return nil
end)
```
The above is a bad example as you don't actually need the stats data given.
It would be better to register a `dignode` callback and call `awards.unlock()`
if the condition is met.
## Trigger Types
The trigger type is used to determine which event will cause the trigger will be
fulfilled. The awards mod comes with a number of predefined types, documented
in [Builtin Trigger Types](#builtin-trigger-types).
Trigger types are registered like so:
```lua
awards.register_trigger("chat", {
type = "counted",
progress = "@1/@2 chat messages",
auto_description = { "Send a chat message", "Chat @1 times" },
})
minetest.register_on_chat_message(function(name, message)
local player = minetest.get_player_by_name(name)
if not player or string.find(message, "/") then
return
end
awards.notify_chat(player)
end)
```
A trigger type has a type as well, which determines how the data is stored and
also how the trigger is fulfilled.
**Trigger Type Types:**
* **custom** requires you handle the calling of awards.unlock() yourself. You also
need to implement on_register() yourself. You'll also probably want to implement
`on_register()` to catch awards registered with your trigger type.
* **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.
If `key` is an item, then you should also add `key_is_item = true` to the
trigger type definition.
As said, you could use a custom trigger if none of the other ones match your needs.
Here's an example.
```lua
awards.register_trigger("foo", {
type = "counted",
progress = "@1/@2 foos",
auto_description = { "Do a foo", "Foo @1 times" },
})
minetest.register_on_foo(function()
for _, trigger in pairs(awards.on.foo) do
-- trigger is either a trigger tables or
-- or an unlock function.
-- some complex logic
if condition then
awards.unlock(trigger)
end
end
end)
```
## Award Difficulty
Difficulty is used to determine how awards are sorted in awards lists.
If the award trigger is counted, ie: the trigger requires a `target` property,
then the difficulty multipler is timesd by `target` to get the overall difficulty.
If the award isn't a counted type then the difficulty multiplier is used as the
overal difficulty. Award difficulty affects how awards are sorted in a list -
more difficult awards are further down the list.
In real terms, `difficulty` is a relative difficulty to do one unit of the trigger
if its counted, otherwise it's the relative difficulty of completely doing the
award (if not-counted). For the `dig` trigger type, 1 unit would be 1 node dug.

## Registering Trigger Types
```lua
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,
-- "counted_key" only, true if the key is an item name. On notify(),
-- any watched groups will also be notified as `group:groupname` keys.
key_is_item = true,
})
```
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
# API
* awards.register_award(name, def), the def table has the following fields:
* `description` - the title of the award. Required.
* `difficulty` - see [Award Difficulty](#award-difficulty).
* `requires` - list of awards that need to be unlocked before this one
is visible.
* `sound` - `SimpleSoundSpec` table to play on unlock.
`false` to disable unlock sound.
* `image` - the icon image, use default otherwise.
* `background` - the background image, use default otherwise.
* `trigger` - trigger definition, see [Builtin Trigger Types](#builtin-trigger-types).
* `on_unlock(name, def)` - callback on unlock.
* awards.register_trigger(name, def), the def table has the following fields:
* `type` - see [Trigger Types](#trigger-types).
* `progress` - used to format progress, defaults to "%1/%2".
* `auto_description` - a table of two elements. Each element is a format string. Element 1 is singular, element 2 is plural. Used for the award description (not title) if none is given.
* `on_register(award_def)` - called when an award registers with this type.
* "counted_key" only:
* `auto_description_total` - Used if the trigger is for the total.
* `get_key(self, def)` - get key for particular award, return nil for a total.
* `key_is_item` - true if the key is an item name. On notify(),
any watched groups will also be notified as `group:groupname` keys.
* 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
## Triggers
## Builtin Trigger Types
Callbacks (register a function to be run)
"dig", "place", "craft", "death", "chat", "join" or "eat"
* dig type: Dig a node.
* node: the dug node type. If nil, all dug nodes are counted
* place type: Place a node.
* node: the placed node type. If nil, all placed nodes are counted
* eat type: Eat an item.
* item: the eaten item type. If nil, all eaten items are counted
* craft type: Craft something.
* item: the crafted item type. If nil, all crafted items are counted
* death type: Die.

or nil for total deaths.
* chat type: Write a chat message.
* join type: Join the server.

* See Triggers
* eat type: Eat an item.
* item: the eaten item type. If nil, all eaten items are counted
