Sprite.tint is the tint color to apply to the sprite image. A tint of
for example, will make white pixels in the sprite image appear red; other
colors will be mixed with (technically, multiplied by) red.
Assigning a tint color with an alpha less than 255 (FF) will make the
sprite semi-transparent. In the extreme, setting a tint of
will make the sprite invisible (though this is not as efficient as simply
removing the sprite from the display sprites list).
sp = new Sprite sp.image = file.loadImage("/sys/pics/Wumpus.png") display(4).sprites.push sp sp.tint = "#00FF0088" // semi-transparent green
