Button Sequence Input

Is there a relatively simple way, with WPILib or without, to make the code be able to detect an input of a sequence of buttons as oppose to holding them all down? Like a cheat code.

For example, if the driver entered the sequence A B X Y on an xbox controller some LEDs would flash. This mean that they are only pressing one at a time but in sequence.

Re: Button Sequence Input

Code:

int state = 0;



while{

if buttonA && state == 0

state ++;



if buttonB && state == 1

state ++;



if buttonX && state == 2

state++;



if buttonY && state == 3

state ++;



if buttonBack

state = 0;



if state == 4

{action

state = 0;

}

This is Java-focused pseudocode, but it should be enough to get you started.

Shouldn't the state be reset to 0 if a button not in the A B X Y sequence is pressed?

As the code stands, the sequence A B Z X Y would be accepted.
