"It's not like I'm going to buy an extension for 30$!!! I'm gonna make it myself >:)"

This is a FREE and EASY-TO-USE string parser for GameMaker Studio 2!  

It includes most of the necessary stuff to implement basic code!

🛠️ 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

• Parentheses work!  
• 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() {}`)

• 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`
