windows

Press RESET immediately, All! I wonder if anyone has ever done overlapping windows on the Spectrum? so that the output of information is possible not only in the top window? I only saw this in DosX to Dickie, when messages were written to the log under window Z-MODEM or EMSI. You probably need to have an image of each window in memory as it is on the screen. And when outputting, see which parts of the line end up on the screen and display only them. So, when drawing each point, you need to check the coordinates all other windows and their depth in order to find out whether the point will be on the surface. You can (and should) of course limit yourself to familiar places of 8x8 points, but when outputting each byte, there are still a lot of checks. You can for example limit the number of windows on the screen to 255 and for each familiar place enter byte of belonging to the window - only 768 bytes are needed. But when outputting each byte you need to check whether it falls into the current window or even into the screen area. :-( You can do the opposite, for each window familiarity there is a pointer in memory on the screen. But this is true for any manipulations with windows (moving, changing sizes, depth...) you need to recalculate all pointers for each window. I remember how this was done in the sprinter - everything is purely hardware. Maybe there is some quick way?
