How would I add a cheat code to a title screen

Raptorkillz It still doesn't work

Well try to find out why it doesn't work. It's called debugging and it's an essential part of programming.

Raptorkillz func _input(e):
for a in InputMap.get_actions().filter(func(aa): return e.is_action_pressed(aa)).slice(0,1):
s += a if not s else " " + a
for k in cheats.keys(): if s.contains(k): code_entered.emit(cheats[k]); s = ""

is this function even correct?

im not fond of lambdas because its convoluted.

i dont like this line:

s += a if not s else " " + a

Seems like if s - the entered cheat sequence is nothing/empty then you start new sequence with " " a space at the beninging. So it will never match the cheat or i maybe wrong here?

also the last line

for k in cheats.keys(): if s.contains(k): code_entered.emit(cheats[k]); s = ""

does ; at the end or signal.emit() means if condition fails then do - s = ""??

kuligs2 is this function even correct?

It is. I wrote it. In a compacted tabletdev style

Raptorkillz Use a trivial test example.

• use actions you know 100% are defined and map 1:1 to physical input, because you might have messed up something with your action definitions
• use trivial sequence to speed up your testing, because you're testing how the parts of your code are communicating so the actual sequence is not important
• print immediately at the start of the signal handler
• print the sequence as it builds up
• double check your signal connections
• be sure to catch and understand all error messages the engine might be reporting
• If you can't use print() on your dev platform - use a different platform or set things up in a way so you can see your prints. Developing without printing is not a very wise thing to do. It just makes tracking the flow of your code needlessly more difficult.

class_name CheatCodeCapture extends Node
signal cheat_code_entered(name: String)
var s: String
var cheats: Dictionary = {"ui_left ui_right" : "cheat1"}

func _input(e):
	for a in InputMap.get_actions().filter(func(aa): return e.is_action_pressed(aa)).slice(0,1):
		s += a if not s else " " + a 
		print("current sequence: ", s) # debug
		for k in cheats.keys(): if s.contains(k): cheat_code_entered.emit(cheats[k]); s = ""

func _ready():
	cheat_code_entered.connect(on_cheat)
	
func on_cheat(name):
	print(name) # debug

kuligs2 Here's an "educational" version for easier understanding:

class_name CheatCodeCapture extends Node
signal cheat_code_entered(name: String)
var action_sequence: String
var cheatcodes: Dictionary = {"ui_left ui_right" : "cheat1"}

func _input(event):
	# iterate through actions defined in input map
	for action in InputMap.get_actions():
		if event.is_action_pressed(action):
			# accumulate actions
			if not action_sequence.is_empty():
				action_sequence += " " # insert space between actions
			action_sequence += action
			# check if the current action sequence is present in any of cheatcodes
			for code in cheatcodes.keys():
				if action_sequence.contains(code):
					# action sequence found, emit the signal and clear the accumulated sequence
					cheat_code_entered.emit(cheatcodes[code])
					action_sequence = ""
			break

Raptorkillz Well, just add that sequence to the dictionary. But as I said you need to check that your actions are properly set up. To which input events do you have those gm_* actions mapped?

Raptorkillz Those are just action names. This doesn't show to what input events they are mapped.
