Welcome... Today we continue with some rendering optimization ideas, focusing on a concept known as dirty rectangles in programming circles. While there's a number of different methods, in this video we look through code that uses a map as background replacement, allowing the redraw code to selectively refresh parts of the backdrop each frame instead of the whole thing. The code computes the redraw percentage each frame, which is often lower than 50%, in the sprite scene saving not only processing time by lowering a games system requirements.
PlayBasic LIVE: Basic Optimization with overview of forums (2017-04-29)
Here's a live video basically talking about the forums and code optimizations mainly.. I'm really just testing video recording on a different machine with a head set mic etc.. sadly the results are pretty sucky, but content is ok so here it is
