Designing Games with Game Maker - YoYo Games

keep the aspect ratio (ratio between width and height) the same. The third option is to scale
such that the window or screen is completely filled. This can lead to distortions in the image
(in particular in windowed mode when the user can resize the window).
Interpolate colors between pixels
When checked, colors of pixels in sprites, backgrounds, and tiles that are not aligned with
pixels on the screen will be interpolated. This in particular is the case when they are scaled,
rotated, or placed at non-integer positions. Interpolation makes movement smoother but can
also give a blurred effect. (Also for tiles it can lead to cracks between them, if not carefully
designed.)
Color outside the room region
When the room does not completely fill the window or screen there is some area unused
around it. Here you can specify the color of the area.
Allow the player to resize the game window
When checked in windowed mode the user can change the size of the game window by
dragging with the mouse at its corners.
Let the game window always stay on top
When checked in windowed mode the game window always stays on top of other windows.
Don't draw a border in windowed mode
When checked in windowed mode the game window will not have a border or a caption bar.
Don't show the buttons in the window caption
When checked in windowed mode the window caption will not show the buttons to close the
window or to minimize or maximize it.
Display the cursor
Indicates whether you want the mouse pointer to be visible. Turning it off is normally faster
and nicer. (You can easily make you own cursor object in Game Maker.)
Freeze the game when the form looses focus
When checked, whenever the player brings some other form to the top (e.g. another
application) the game freezes until the game window again gets the focus.
