🛠️ HOW TO CREATE YOUR OWN INSTANCE:

1. Use with(instance_create_layer(x, y, "Instances", obj_custom)) { // Code here }. You should replace x and y with your desired position. This will create a blank obj_custom in the current room.
2. For your instance to run GML events like a 'normal' GameMaker instance, you will need to set them as functions using those instance variables: event_create, event_destroy, event_step, event_beginstep, event_draw, event_drawgui, event_roomstart, event_roomend
3. Your functions should be simply defined like this: variablename = function() { // Code here }. Any variables used in these functions will be set to the instance.

FULL EXAMPLE: with (instance_create_layer(room_width / 2, room_height / 2, "Instances", obj_custom)) { sprite_index = spr_test1;

    event_step = function() {
            var key_sound = keyboard_check_pressed(ord("Z"));
         
            if key_sound {
                    audio_play_sound(sfx_noise, 1, false);
            }
    }

}

📝 Notes / TODO

• You should ALWAYS put a ; at the end of each line! (except for the statements that need {})
• Variables can be declared with nothing, var , or global. before their names, but when using with and declaring without a prefix will set the variable on the instance
• You can store custom defined functions in a variable! (ex: var _func = function() {})
• Parentheses work!
• Single-line comments (//) and multi-line comments (/* */) work!
• Array setting/getting is done using array_set and array_get
  (No array[index] support yet)
• Struct setting/getting is done using struct_set and struct_get
• idk what to put here 🤷
