Legacy GM efficient way of doing this?

[yasin]

I have here a working code that I always use but my question is can this be done more efficient/easier?

if (mouse_check_button_released(mb_left)){
      if variable == 0{
                   variable = 1
            }
      else
            {
                  variable = 0
            }
};

if (mouse_check_button_released(mb_left)) variable=1-variable

Also make sure you are only checking the mouse input ONE time in your entire step events. I've seen lots of people may check an input multiple times in different codes. Check inputs one, set variables and then check those variables.

another way:

variable = !variable;
