Designing Games with Game Maker - YoYo Games

images file formats are supported, e.g. .bmp, .jpg, .tif, and .gif. For a gif file the number of
subimages is automatically decided based on the number of subimages in the gif file. Other
settings for the sprite, e.g. whether it is transparent or not, are not changed. You can use this
action to avoid storing all sprites in the program itself. For example, at the beginning of a level
you can replace sprites by the actual character sprites you want to use. DON'T change a sprite
that is at that moment being used in an instance in the room. This might give unwanted
effects with collisions. This action is only available in the Pro Edition.
Replace Sound
With this action you can replace a sound by the contents of a file (.wav, .mid, or .mp3). You
specify the sound and the filename. This avoids having to store all the sounds in the game
itself. For example, you can use different pieces of background music and pick the one you
want to play. DON'T change a sound while it is playing. This action is only available in the
Pro Edition.
Replace Background
With this action you can replace a background by the contents of a file. Many different images
file formats are supported, e.g. .bmp, .jpg, .tif, and .gif. You specify the background and the
filename. This avoids having to store all the backgrounds in the game itself. DON'T change a
background that is visible. This action is only available in the Pro Edition.
More control actions
Some additional control actions are available in advanced mode. The following actions are
added:
Execute Script
With this action you can execute a script that you added to the game. You specify the script
and the maximal 5 arguments for the script.
Call Parent Event
This action is only useful when the object has a parent object. It calls the corresponding event
in the parent object.
