A very simple Line of Sight (LOS) implementation with Unity physics ray casting system, including the following features:
- LOS related events
Register callbacks for static events in LOSManager. The available events are OnEnter and OnExit, which are invoked when a LOSTarget enters or exits the line of sight of one LOSSource, and instances of both the LOSSource and LOSTarget are sent to the listeners:
LOSManager.OnEnter += (source, target) =>
{
Debug.Log($"{target.name} enters the sight of {source.name}");
};- Sector shaped mesh generation
LOSMesh is for sector-shaped mesh generation, with some configurations:
'Associated LOSSource' : read angle and radius parameters from the given LOSSource
'Resolution' : the resolution for the sector
'Default FOV' : the angle of the sector if no LOSSource associated
'Default Max Dist' : the radius of the sector if no LOSSource associated
'Draw Simple Sector' : turn off target and obstacle detection, only draw sectors
'Draw Hidden' : draw the area blocked by obstacles
'Draw Sight' : draw the bright area that is not blocked by any obstacles
'Fill UV' : generate a mesh with uv
'Auto Regenerate' : regenerate mesh every frame
- Shader and texture tools for sector-shaped mesh
Shader: use sector-specific textures which supports border settings
Texture tool: convert a 90-degree sector image from Cartesian to the polar coordinate system to better support different radii and angles by setting borders. Right-click on the original texture and select "C2P".
The sample scene contains a composite example.
