SOLVED What does a function in a script do without arguments (in GameMaker 2.3)?

[jobjorgos]

What is the difference between script example A and example B?

Example A
script_jump:

function scr_custom_input_menu_character_jump(){
    do_character_jump=1;
}

Example B
script_jump:

function scr_custom_input_menu_character_jump(){

}
do_character_jump=1;

I have script_jump in the step event of the player, but somehow ONLY in Example B the variable do_character_jump gets the value 1.
Does a function do anything at all without arguments?

The reason I use scripts, is because I don't want 25000 rows of code in the players step event, but put most code in 'container' scripts to keep a clear overview

Um... the second script has the body of the function outside the function. That's the difference. You don't put script_jump in the step event of the player - you put a call to the function scr_custom_input_menu_character_jump() if that's what you want to do.

To answer your original question in another way, saying:

function scr_custom_input_menu_character_jump(){
    //code or no code
}

declares a function, it doesn't call it and the code inside of it doesn't run until you call it. To put it yet another way, it's the difference between creating and using the function.

awe thanks for the answers, it is really clear for me now.
