| Sep 18, 2012 at 15:15 | comment | added | jujumbura | I'd like to try only redrawing certain areas, but I am unsure how to accomplish it for my desired effect. My game is designed to have a large scrolling world in X & Y ( to-down view ), with a number of "entity" sprites moving on top of that world. The world BG is entirely static, but since it can scroll, it seems like I still need to redraw it to the canvas each frame. I have tried drawing the BG into a large offscreen canvas and then drawing a subsection into the main one, but it doesn't seem to get me much performance gain. Are there better ways of accomplishing the scrolling BG effect? | |
