2D line-of-sight mesh generator and renderer for room based Unity2D games. This generator works by checking the sightlines in a view origin room, then check what doors are visible from that point and generating the views trough whatever doors are visible. This approach seemed like a good idea to me because it limits the amount of raycasts there need to be done in one time, no need to check every corner point in the game, only the ones in the relevant room. The system can draw as many line-of-sight mesheses as possible (in theory).
I updated this project so that instead of rendering the line of sight as a camera-shader it writes the result to an instantiated panel, this is more useful because the camera can be moved without impacting how the los is rendered. It also allows for a fog of war so that areas which have been revealed but are no longer in sight can still be seen for how they looked when last seen. (that sentence is garbage but I'm tired af)
I wrote this asset for a game I'm working on and it seemed like a nice idea to open source it. If you intend to use this code you should know that I am a hobbyist with no formal background in programming, therefor there are bugs and it is incredibly unlikely that the asset is as optimised as it could be.
In the future I might rewrite this to make use of the ECS, the code is really data driven and segmented so it seems feasible and might be a nice project.
I'm open to contributions to the project.
