Designing Games with Game Maker - YoYo Games

MCI_command(str) This functions sends the command string to the Windows
multimedia system using the Media Control Interface (MCI). It returns the
return string. You can use this to control all sorts of multimedia devices. See
the Windows documentation for information in how to use this command. For
example MCI_command('play cdaudio from 1') plays a cd (after you
have correctly initialized it using other commands). This function is only for
advanced use!
Splash screens, highscores, and other
pop-ups
In this section we will describe a number of functions that can be used to display splash
screens with videos, images, etc., to display messages and ask questions to the player, and to
show the highscore list.
Splash screens
This functionality is only available in the Pro Edition of Game Maker.
Many games have so-called splash screens. These screens show a video, an image, or some
text. Often they are used at the beginning of the game (as an intro), the beginning of a level,
or at the end of the game (for example the credits). In Game Maker such splash screens with
text, images or video can be shown at any moment during the game.
Default these splash screens are shown inside the game window, but it is also possible to
show them in a separate window. The game is interrupted while the splash screen is shown.
The player can return to the game by pressing the escape key or by clicking with the mouse in
the window. (These settings can be changed; see below.)
The following functions can be used to display the splash screens:
splash_show_video(fname,loop) Shows a video splash screen. fname is
the name of the video file. Whether a particular movie file is supported
depends on the drivers on the machine. Typically you can use .avi, .mpg, and
.wmv files but avoid special codecs. You best put this file in the folder of the
game yourself or in a subfolder. loop indicates whether to loop the video.
