Syntax
addOverlay (thisFile, atX, atY);
Purpose
Loads an image from the file handle thisFile and overlays it onto the screen. Bright magenta (255, 0, 255 or #FF00FF) is used as the transparency colour, making is possible to add irregular shapes.
The values atX and atY define the top left corner of the area into which the image will be added. If the value of atX is CENTRE (or CENTER) the image will be added halfway across the window. If the value of atY is CENTRE (or CENTER) the image will be added halfway down the window.
NB: Should any parallax layers exist, they will be visible "through" any areas of the background image filled in with bright cyan (0, 255, 255 or #00FFFF). You can add parallax layers using the parallaxAdd function.
Return value
No return value.
Example
sub init () {
addOverlay ('someImage.tga', CENTER, CENTER);
}
