I’ve given the shadow system some much needed love, so I figured I’d throw up a quick demo. It looks considerably better than the previous version. Here’s what changed:
- Removed the horizontal “swing” effect by skewing every vertex in a sprite based on its position relative to each light source, rather than skewing all vertices by a uniform value. This also has the added effect of allowing shadows to appear on both sides of a building when standing in front of it.
- Added a transparency lerp when close to the object’s pivot (vertically). This eliminated the vertical “swing” effect, and corrected issues with large objects (the inn) not being tall enough to properly overlap a large light source.
- Blur added. This also corrected an issue where the tops of fence posts appeared warped.
- Added a configurable vertical shadow offset for each sprite, which makes tree shadows look significantly better.
