IMAGEREF (function)

With the IMAGEREF instruction you can retrieve the reference to an image, an ATLAS or a SEQUENCE, which can then be used in place of the original image, as a placeholder. This instruction is very useful when you want to diversify the graphics to use, while maintaining the same game logic.
