Engine Crashes Repeatedly on Startup

If the V2X simulator crashes repeatedly during launch, try clearing temporary and cached data:

1. Fully close the application (and Unity Editor, if applicable).
2. Navigate to your simulator’s root directory (or Unity project folder if running from source).
3. Delete the following folders (if they exist):
4. Logs/ (in your first try only remove the logs)
5. Library/
6. Temp/
7. Relaunch the simulator.

Note:
Unity regenerates these folders automatically on startup. Removing them forces a clean reimport of assets and clears corrupted cache files, which often resolves persistent crashes or startup failures.

Stop Lines Don't Work with Traffic Lines

• StopLine Reference Not Assigned
  The TrafficLane component requires a StopLine reference, and the referenced StopLine GameObject must have a TrafficLight component. If either condition is not met, the code will skip processing the lane entirely.

• Waypoint Positioning
  The first waypoint of your approach lane must be positioned at or before the physical stop line. If the waypoint is placed after the stop line, vehicles will cross the stop line before stopping.

• Lane Connectivity (most important reason)
  The approach lane must include the intersection lane in its "Next Lanes" array. Without this connection, vehicles cannot "look ahead" to detect the traffic light state.
