I've looked around searching an example on how to make a fighter game input like street fighter or tekken, and i've figured some of it out but im still having trouble on how to know when the player puts a series of inputs. Heres my code:

var input_buffer = []
 var input_buffer_max_size = 5
 var input_previous_buffer = "N"
 var input_angle = ""

 func input_movement():
	var input_direction = Input.get_vector("move_left", "move_right", "move_up", "move_down").normalized()
	
	if input_direction.length() < 0.2:
		input_angle = "N"
	
	if input_direction.x != 0 || input_direction.x >= 0:
		if input_direction.y < 0:
			input_angle = "8"
			if input_direction.x > 0:
				input_angle = "9"
			elif input_direction.x < 0:
				input_angle = "7"
		elif input_direction.y > 0:
			input_angle = "2"
			if input_direction.x > 0:
				input_angle = "3"
			elif input_direction.x < 0:
				input_angle = "1"
		elif input_direction.x > 0:
			input_angle = "6"
		elif input_direction.x < 0:
			input_angle = "4"

func handle_attack_input():
	if input_angle != input_previous_buffer:
		input_buffer.push_back(input_angle)
		input_previous_buffer = input_angle
	
	if input_buffer.size() > input_buffer_max_size:
		input_buffer = input_buffer.slice(input_buffer.size() - input_buffer_max_size, input_buffer.size())

func check_moves():
	if input_buffer.find("2, 3") > -1:
		print_debug("COMBO WORKED")

I have the input_angle set to numbers as like on a numpad with "5" on the numpad being "N" or neutral and "8" being up and so on. If i try printing the array called input buffer, it does work as i want (OUTPUT):
(6) ["3", "2", "N", "2", "3"]
but its not printing when im trying to find the series of inputs. How can i fix this? Thanks.

    this test will never trigger for joystick input (unless the joystick is held exactly straight), because you normalized the vector so it has length 1. you need to do this test first, then normalize.

      Most likely, “find” looks for a single string but what you mean to do instead is check multiple. Try something like input_buffer[0]=“8” and input_buffer[1]=“6”.

          axolotl hmm, but that would only work if they attempted the combo at the beginning of the input_buffer. How would i know if they also put it like towards the end of the input_buffer?
