Overview
Ray queries cast NumRays rays to intersect the scene per each entity. The image below shows a SteeringSystemAsset with one group of ray behaviors. The selected ray query here is Sweep2DCreateRaysJobWrapper. It casts NumRays rays, to max distance of MaxDistance. The Sweep2DCreateRaysJobWrapper casts the rays in section of a circle with a given field of view FOV. The rays will only hit objects matching the selected LayerMask.
Image of a SteeringSystemAsset. Sweep2DCreateRaysJobWrapper is selected as implementation of ray query to use for the EnvironmentAvoidanceJobWrapper behavior.
Video showing ray query visualized. The green arrows show rays which did not intersect the scene, the red arrows show a hit.
DebugRayJobWrapper can help to visualize a ray query, as in the video.
