Simple Achievement System for Playdate games

This repository is an example of how to use Tanuk_Achievement. If you are just looking for the lib, go into the lib/ folder.

Usage

First, you need to import the library with import "lib/Tanuk_AchievementHandler"

Then, you need to create your list of achievements and how to test them by creating multiple Tanuk_Achievement. You then initialize the Tanuk_AchievementHandler with this list.

local arrAchievements = {}
table.insert(arrAchievements, Tanuk_Achievement("Great Score!", "You reached an awesome score", function ()
	return someVar >= 10 
end))
table.insert(arrAchievements, Tanuk_Achievement("Weird Combo", "If that's how you want to play", function ()
	return pd.buttonIsPressed(pd.kButtonLeft) and pd.buttonIsPressed(pd.kButtonB)
end))
table.insert(arrAchievements, Tanuk_Achievement("Good start!", "Welcome to the game", function () return true end)) -- This is going to be triggered when the game is started for instance

Finally, don't forget to add the following line to your update loop. Tanuk_Achievement uses both sprites and timers so you also need to make sure their update functions are called in the update loop.

function pd.update()
	gfx.sprite.update()
	pd.timer.updateTimers()
	__achievementHandler:checkAchievements() -- Important to check the achievements
end

Configuration

Tanuk_Achievement also contains a description field. This can be used to display more information if you have a dedicated achievement screen for instance. Tanuk_AchievementHandler takes the following arguments:

Argument	Mandatory	Description
arrAchievements	yes	Array of Tanuk_Achievement
fnNotification	no	Allows to customize how the achievement notifications are displayed
frameCheck	no	How often should the achievements be checked? Default is 30 frames
fntPath	no	Path to a customized font to use when displaying the achievement name
imgNotificationPath	no	Path to a customized background image to use when displaying the achievement
imgIconPath	no	Path to a customized image to use as icon when displaying the achievement

Credits

Credits are not required, but are always nice! I am always curious to see where this code may end as well!
