# CarMain

Main script for controlling the scene. The controllable vehicles and the logic of the scene are managed here.

- Reads, manages and applies all user input (keyboard, joystick, etc). 
- Allows vehicle selection and driving.
- Controls the camera modes.
- Configures the camera and shadows for quality modes (F12).
- Shows the vehicle's dashboard (speed, driving aids, etc).
- Shows the help window (H).
- Shows the vehicle's telemetry window (B) if a [CarTelemetry](wiki:CarTelemetry) script is available in the same GameObject.
- Offers the slow time feature.

This script is added to a _Main_ GameObject intended to hold the control scripts for the scene.
