Here is an example : https://www.dropbox.com/s/9jerbdwpl6q56ty/IMG_0694.MOV?dl=0 in BASIC :-) It shows a full-width "sprite" but it doesn't have to be full-width. It can be of any size down to 8x1 pixels. It's always been possible to do some split-screen effects but this is different in a few ways: - it is much more accurate (single cycle) horizontally and can be activated multiple times per raster _line_ - bitmap data is not bound to screen position so the place the desired graphics will get displayed can be chosen arbitrarily, which can be noticed on the video above - moving bitmap data within a block of VASYL RAM is fast. Not nVidia Titan/GDDR6 type of fast ;-) bu still [*](videos below) Combining the three gives a possibility to create multiple movable, animated objects (hardware sprites can still be used on top) as long as [lack of] compositing is not an issue. * - hires bitmap text output and scrolling: invoked once per frame: https://www.dropbox.com/s/ur7x2nbxaic07vx/hires_scroll_once_per_frame.mp4 invoked cotinuously: https://www.dropbox.com/s/kd77duyqf1amvi6/hires_scroll_unrestricted.mp4 -- SD!Received on 2020-07-30 18:00:03
