Sorry english is not my first language.
Help write a script for GMS 2.3.
This is taken from Shaun Spalding's tutorial, GameMaker Studio 2: Action RPG Tutorial (Part 18: Entity Fragments # 2).

You are using old syntax in a new version of GMS. Stop doing that.

IMPORTANT!!! GM 2.3 Users Please Read! Improper script usage generates undefined variable errors

Symptoms to Look For Expand for screenshot: The error is in the Create Event for object . The subject is with a variable name that's either built-in or known to be already declared. The stack trace shows the source as something starting with gml_GlobalScript. For Question Askers You are...

/// @desc scr_Drop_item(xx, yy, [items])
/// @arg xx
/// @arg yy
/// @arg [items]
function scr_Drop_item(xx, yy, items) {
    var _items = array_length(items);
    if (_items > 1) {
        var _angle_per_item = 360/_items;
        var _angle = random(360);
        for (var _i = 0; _i < _items; _i ++) {
            with (instance_create_layer(xx, yy, "Instances", items[_i])) {
            direction = _angle;
            spd = 0.75 + (_items * 0.1) + random(0.1);
            }
            _angle += _angle_per_item;
        }
    } else instance_create_layer(xx, yy, "Instances", items[0]);
}

I suggest that you start with a tutorial on this page that teaches the latest syntax and get used to that first, before trying to work with random tutorials on YouTube that are likely designed for older versions and need manual adjustment to work.
