Finally decided to work on a tile map engine for my flash game framework. Luckily it was a fairly easy task to port existing code from previous engines. I’m actually surprised how well it’s already working with minimal optimizations.
This demo renders 3 map layers. Each layer is rendered in real time which allows easy tile animation. 1000 sprites are interacting with map layer 1.
This opens the door to several new potential game genres.
