What no one has told me yet is if these images one can rotate in rev are images in containers or images as bitmaps. In supercard, you can assign an image as path to disc image file to any grahic object. That object acts as a bounding mask of the image it contains and is independent of the image manipulatins performed to the bitmap within. If you rotate the polygon that holds an image, the image remains virtically oriented while the bounding polygon rotates around it. Or, using quad functionality, you can rotate the internal image and leave the polygon static. But weirdly, it is almost imposible to do manipulate both image and holding graphic in lockstep.

It turns out that RR will truncate a fractional angle for you. (See script below.) It will also accept fractional input to "move image from pt1 to pt2" where the two points have fractional items, but will not accept a fractional input to "Move image to tPt" if tPt contains fractional items. Nor will RR accept fractional input to setLoc but there will be no error message. It just interest a return into the list of points and you get a gap in the line, or nothing if all the points are fractional. I put in a request many years ago asking that RR do all the truncating in the engine. Sooo much simpler. If that request is still active, I would appreciate your vote. (The trouble is that I means I have to keep two sets of books for the graphic points, one for calculating the tangent angle and one for setting the graphic points to display the graphic.) So in summary: Accepts fractional input: Move object from pointA to pointB Set angle of image to tAngle Does not accept fractional input: Move object to tPoint [truncated by sender] _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
