Ok, so… I am beyond frustrated.
I have two sets of Entities; Autos and Roads. I have a Job that is designed to move the cars along the points of the road.
The job executes based on an AutoTag component (and has the Auto’s Transform, the car’s current RoadIdentity and LaneIdentity) During the job I need to loop through the Road Entities (which is passed to the job via a NativeArray) Thing is, when I attempt to get the component’s data I am getting errors. (I have walked away from my development system out of frustration, so atm I don’t have the exact error message)
So basically I am attempting to understand how to access other entities and their data within a job. Thoughts?
