Tanuk_CodeSequence

Provide a cheat code function / sequence recognition for Playdate games. Credits are not required, but let me know if you used this code somewhere, it is always nice to hear :))

Usage

Import the Code Sequence function

Add import "Tanuk_CodeSequence" where you need the function. Note that the CodeSequence will read inputs but will not stop their propagation. This class relies on timers and sprites, make sure that you import the timer and sprite files and update the both of them in the update loop

import "CoreLibs/sprites"
import "CoreLibs/timer"

function playdate.update()
	gfx.sprite.update()
	pd.timer.updateTimers()
end

Create a CodeSequence

Once the function is imported, you can easily create potential code with

-- Example: local myCode = Tanuk_CodeSequence(sequence, callbackReward, [isAllowMultipleCalls])
local sprCode = Tanuk_CodeSequence({pd.kButtonDown, pd.kButtonDown, pd.kButtonRight, pd.kButtonDown, pd.kButtonRight}, function() print("Code Complete") end)
local sprCode2 = Tanuk_CodeSequence({pd.kButtonUp, pd.kButtonDown, pd.kButtonUp, pd.kButtonDown, pd.kButtonDown, pd.kButtonRight}, function() print("Not the Konami code") end, true)

Parameters

A Tanuk_CodeSequence is initialized with 2 or 3 parameters:

• sequence A sequence of input, in order. It takes the standard Playdate input constants: pd.kButtonDown, pd.kButtonUp, pd.kButtonLeft, pd.kButtonRight, pd.kButtonA, pd.kButtonB - see the Playdate documentation
• callbackReward function to call when the code is successful
• isAllowMultipleCalls set to false by default. If set to yes, the code may be triggered multiple times. If set to false, it will only be registered once

Important Note

All CodeSequence are considered as sprites. It means they will be removed if you call playdate.graphics.sprite.removeAll()

Credits

CodeSequence was originally written by Toad, who came up with the idea of using sprites and their update function. The function was then modified by Schyzophrenic
