Hello guys, im a super noob in programming, plz help
I need to get input from 4 buttons then fill an array with the sequence of the input
I connected the button to the script and got a func _on_pressed, but i dont know how to wait for the input calling that function.
On my head i need to run the func _on_pressed inside another function but i dont know how it works sequence[0] = input of any of the 4 buttons sequence[1] = ...
I cant figure it out
if I understand you correctly, you are trying to check what button sequence was pressed after 4 button presses? you can create an array and fill it up with each press.
var button_buffer:Array = []
var button_buffer_index:int = 0
func onpress():
button_buffer[button_buffer_index] = input of button
button_buffer_index = button_buffer_index + 1
if button_buffer_index == 4:
# access the last 4 buttons and analyze
button_buffer[0]
button_buffer[1]
button_buffer[2]
button_buffer[3]
thx for the help,
I had to set the array elements to null, then i worked var button_buffer:Array = [null, null, null, null]

yes of course. My bad. otherwise you would have been writing to a non existing index.
Here’s another option (depending on some details that are unclear in your original description). Create 4 buttons, wire them all to the same signal handler, and pass the button itself as an arg.
Add the button’s name to an array when it’s pressed. When the array contains 4 elements, print it out, and clear it for the next group of 4 buttons.
It’s not clear whether you have 4 buttons or 1 button. Also, it’s not clear what you want to store about the button when it’s pressed, though since you have the button itself in the _onButtonPressed handler below, you can get anything you want (name, group, text, …). Here’s some sample code:
