Hi, kind of new here, but I have an error in my code and wanted to know if I should be worried?
code

extends KinematicBody2D

func read_input():
	IF input.is_action_pressed(*up*):
		pass
	IF input.is_action_pressed(*down*):
		pass
	IF input.is_action_pressed(*left*):
		pass
	IF input.is_action_pressed(*right*):
		pass 

Error
Expected end of statement after expression, got Identifier instead.

               *********

Do I need to fix this?

    Nerd009 Not Only that, but the debug game also crashes when I open it

    IF input.is_action_pressed(up):

    Is "IF" how you're actually spelling that keyword, which should be "if"?

    the debug game also crashes when I open it

    What do you mean by "crash"? That's hard to diagnose without more details.

    IF is not a keyword, it is if. The case of the words matter. Also, it could be an indentation error. You have to intent each block of code one level (such as with a tab), and you can't mix tab and spaces.

    The asterisk instead of quotes is going to cause issues.
    For example *up* should be "up".
