tschak909 Posted March 10, 2007 Share Posted March 10, 2007 sorry, I realised this was a bit out of the scope of the newbie subforum, so am posting here.... I am needing to put together a window algorithm for coarse scrolling...maybe it's just me being up at 3:30 in the morning, and my head is mush, but...... I have a buffer of 32 values, and I need to display 25 of them on screen at a given time, from top, to bottom, and once it hits the bottom, the window needs to warp back around to the top while part of it is still on the bottom.... maybe i'll come up with an answer tomorrow, but.. i wanted to get some input from you guys as well. thanks. :-) -Thom p.s. this is a very difficult challenge for me, because of the limited memory constraints ($FF,x) and stuff...not enough memory..... and I am trying to do the display part of this tight enough to keep the kernel stable.... and i hope i can calculate the new offscreen data for the next 1 or two lines ahead during the overscan or vertical blank.... I was thinking something akin to two counters, c2 = c1 + size of buffer & size of buffer ? .... damn I need to go to bed.... Quote Link to comment Share on other sites More sharing options...
