This single-function extension allows to call ShellExecute from GameMaker: Studio and GameMaker Studio 2 games.

The function execute_shell_simple takes up to 4 arguments:

  • path (required)
    The absolute path to whatever you are trying to run - an executable, a text file, a .url, etc.
    If you are not sure how to get the true path to your file, have the game copy it to save directory (game_save_id).
  • args (optional)
    Command-line arguments to pass. Non-executables will generally ignore these.
    If omitted, defaults to "".
  • action (optional)
    What to do with the file, as per lpOperation in MSDN.
    If omitted, defaults to "open".
  • showCmd (optional)
    One or other magic number (such as 6 for SW_MINIMIZE) from the same MSDN page.
    If omitted, defaults to 5 (SW_SHOW).

Create a text file and open it in default editor:

var _path = game_save_id + "/hi.txt";
var _txt = file_text_open_write(_path);
file_text_write_string(_txt, "Hi! " + date_datetime_string(date_current_datetime()));
file_text_close(_txt);
execute_shell_simple(_path);

Create a text file and open it in Notepad:

var _path = game_save_id + "/hi.txt";
var _txt = file_text_open_write(_path);
file_text_write_string(_txt, "Hi! " + date_datetime_string(date_current_datetime()));
file_text_close(_txt);
var _windir = environment_get_variable("WINDIR");
execute_shell_simple(_windir + "/Notepad.exe", _path);

Create an internet shortcut and open it in default browser:

var _url = "https://yoyogames.com";
var _path = game_save_id + "/shortcut.url";
var _txt = file_text_open_write(path);
// note: use '' instead of @'' in GMS1
file_text_write_string(_txt, @'[{000214A0-0000-0000-C000-000000000046}]
