How to connect multiples nodes?

UnknownUser

I'm making a give change game. You do it through cents and bills, that have a line edit in which you write the necessary amount. How do i get all the numbers written in the various line edits to sum them up?

When the user clicks a submit button, you can have a function called on the signal callback. Then in that function you can read each text box and perform any calculation you need. For example:

var bill_box = get_node("bill_box")
var billNum = int(bill_box.text)
var cent_box = get_node("cent_box")
var centNum = int(cent_box.text)
# example calculation
var totalNum = billNum * 100 + centNum
# do something with total num
return totalNum

It doesn't work.

func _process(delta):
	if Input.is_action_just_pressed("ui_accept"):
		_randomize_my_variable()
		Line_Edit = get_node("LineEdit")
		LineNum = int(Line_Edit.text)
		Line_Edit2 = get_node("LineEdit2")
		LineNum2 = int(Line_Edit2.text)
		TotalNum = LineNum * 0.25 + 0.50 * LineNum2
		if TotalNum == nd:
			count += 1
		else:
			count += 0

this is how i do it but only one LineEdit:

func _on_LineEdit_text_entered(new_text):
	new_text = int(new_text)
	new_text = 0.25*new_text
	if new_text == nd:
		count+=1
	else:
		count+=0

func _on_LineEdit2_text_entered(new_text2):
	new_text2 = int(new_text2)
	new_text2 = 0.50*new_text2
	if new_text2 == nd:
		count+=1
	else:
		count+=0

func _on_LineEdit3_text_entered(new_text3):
	new_text3 = int(new_text3)
	new_text3 = 1*new_text3
	if new_text3 == nd:
		count+=1
	else:
		count+=0

func _on_LineEdit4_text_entered(new_text4):
	new_text4 = int(new_text4)
	new_text4 = 2*new_text4
	if new_text4 == nd:
		count+=1
	else:
		count+=0

func _on_LineEdit5_text_entered(new_text5):
	new_text5 = int(new_text5)
	new_text5 = 5*new_text5
	if new_text5 == nd:
		count+=1
	else:
		count+=0

I see a few problems with the code.

    new_text = int(new_text)
    new_text = 0.25*new_text
    if new_text == nd:

new_text should be an integer or a float. It can't be both. First you cast the String as an integer (a whole number), then you multiply by 0.25, which will result in a float (which will likely cause issues). If you want float, then cast as a float on the first line. Also, when you compare new_text to nd, what is nd? Basically you will be comparing two floats for equality, which almost never works. Because floating point numbers are not exact. If you must compare, it should be within some small margin of error, like:

if abs(next_text - nd) < 0.001:

Also, you have code like this:

    if new_text2 == nd:
        count+=1
    else:
        count+=0

count+=0 does nothing. It just adds zero to a number, which is the same number. So that might not be what you want, or you can just remove the else clause altogether.

Finally, you probably want to put your input code on _input or use signals.

func _input(event):
      if event.is_action_just_pressed("ui_accept"):
      _randomize_my_variable()
      # rest of code ...

func _ready():
	get_node("LineEdit").connect("pressed", self, "on_click")

func on_click():
      _randomize_my_variable()
      # rest of code ...

Thanks! Even if the problem was _randomize_my_variable() being before than the rest of the code XD (because that changed nd(number difference), so totalNum was always incorrect).
