Camera System

This page covers the RCC Camera: adding it to a scene, its six modes, the TPS and orbit settings, occlusion, hood and wheel camera mounts, and switching modes from code.

Quick Start

Open your scene. It needs a vehicle registered as the player vehicle (see Quick Start).
Select Tools → BoneCracker Games → Realistic Car Controller → Create → Cameras → Add RCC Camera To Scene.
If a Disable Other Cameras? dialog lists your old Main Camera or AudioListener, click Disable.
Press Play. The camera follows the player vehicle. Press C to cycle camera modes.

Changed in V6: You no longer have to delete Unity's Main Camera. Add RCC Camera To Scene offers to disable the other enabled cameras tagged MainCamera and the other AudioListeners. Nothing is deleted, and Ctrl+Z undoes the change. Cameras that render to a texture or belong to a vehicle or an Enter-Exit character are left alone.

If the scene already has an RCC Camera, the menu shows Scene has RCC Camera already! and selects the existing camera instead.

How It Works

One camera handles every mode. RCC_Camera re-parents itself to the right mount for each mode, such as a hood camera, a wheel camera or the fixed camera. The prefab (Prefabs/RCC_Camera.prefab) has this hierarchy:

Plain text

RCC_Camera        (RCC_Camera component)
└── Pivot
    └── Camera    (Camera, Flare Layer, AudioListener; tag MainCamera)

The camera targets whatever vehicle the Scene Manager registers as the player vehicle. The Target Settings → Player Vehicle field shows the current target.

The single RCC Camera moves under a different parent in each mode; the table shows each mode's mount and field of view.

Camera Modes

Pressing C cycles through the modes in this order: TPS → FPS → WHEEL → FIXED → CINEMATIC → TOP → TPS. Any mode that isn't set up is skipped. See Input System for the gamepad and wheel bindings.

The C key walks this ring from TPS to TOP and back; a mode whose requirement is missing is skipped.

Mode	What it shows	Requirement
TPS	A chase camera behind the vehicle.	Always available.
FPS (Hood)	The view from the vehicle's hood or driver position.	The vehicle has a child with `RCC_HoodCamera`.
WHEEL	A low view from a mount near a wheel.	The vehicle has a child with `RCC_WheelCamera`, and Use Wheel Camera Mode is on.
FIXED	A stationary camera that tracks the car and moves ahead of it again once the car is farther than Max Distance (shipped 50).	Use Fixed Camera Mode is on. If the scene has no `RCC_FixedCamera`, one is created automatically.
CINEMATIC	Animated shots around the vehicle.	Use Cinematic Camera Mode is on. For animated shots, drag `Prefabs/RCC_CinematicCamera.prefab` into the scene. Without it, RCC creates an empty `RCC_CinematicCamera` that only gives a static view from 10 m in front of the car.
TOP	An angled overhead view, orthographic by default.	Use Top Camera Mode is on. It is on in the shipped prefab.

All 12 demo vehicles in Prefabs/Vehicles/ have a hood camera. All except F1 have a wheel camera.

TPS: the chase camera behind the car. Always available.

FPS (Hood): the view from the vehicle's RCC_HoodCamera mount.

WHEEL: a low view from the vehicle's RCC_WheelCamera mount.

FIXED: a stationary roadside camera that tracks the car and repositions once the car is farther than Max Distance.

CINEMATIC: animated shots from Prefabs/RCC_CinematicCamera.prefab.

TOP: the angled overhead view, orthographic by default.

Look Back (hold B) flips the TPS camera to face backwards. Use Auto Change Camera (shipped off) cycles the mode automatically every 10 seconds.

TPS Camera Settings

These are in the TPS Camera Settings foldout of the RCC_Camera Inspector. The defaults are the values in the shipped prefab.

Inspector label	What it does	Shipped default	Range
Lock X Rotation	The camera pitch follows the vehicle's pitch.	On	—
Lock Y Rotation	The camera yaw follows the vehicle's yaw.	On	—
Lock Z Rotation	The camera roll follows the vehicle's roll.	Off	—
Free Fall	Stops following the vehicle's rotation while the vehicle is airborne.	On	—
Distance	How far behind the vehicle the camera sits. Auto Focus overrides it.	6	0 – 20
Height	How high above the vehicle the camera sits. Auto Focus overrides it.	2	0 – 10
Rotation Damping	How fast the camera turns to follow the vehicle. Higher is snappier.	0.6	0 – 1
Dynamic (based on velocity)	Moves the camera back and forth slightly with acceleration.	On	—
Max Tilt Angle	The largest roll tilt produced by sideways speed.	15	0 – 25
Tilt Multiplier	Scales the tilt.	0.5	0 – 10
Yaw Offset	Extra yaw angle.	0	-45 – 45
Pitch Offset	Extra downward pitch angle.	8	-45 – 45
Min FOV	Field of view at standstill.	50	10 – 90
Max FOV	Field of view at 150 km/h and above.	70	10 – 160
Position Offset	Offsets the follow point, in vehicle space.	(0, 0, 0.25)	—
Auto Focus	Sets Distance and Height from the vehicle's size over 3 seconds whenever the target changes. Turn it off to use your own values.	On	—
Auto Reverse	While the vehicle reverses, the camera swings to the front and looks in the direction of travel.	On	—
Enable Collision Effects	Shakes the camera and briefly changes its FOV on hard impacts. TPS mode only.	On	—

With the shipped Min FOV 50 and Max FOV 70, the TPS field of view grows in a straight line with speed and stays at Max FOV from 150 km/h.

Other foldouts:

Foldout → Inspector label	What it does	Shipped default
Hood (FPS) Camera Settings → Hood Camera FOV	Field of view in hood mode.	60
Wheel Camera Settings → Wheel Camera FOV	Field of view in wheel mode.	60
Top Camera Settings → Use Orthographic	Renders the top view orthographically.	On
Top Camera Settings → Top Camera Angle	Rotation of the top view.	(45, 45, 0)
Top Camera Settings → Top Camera Distance	Distance from the vehicle.	100
Top Camera Settings → Max Z Distance Offset	How far the view shifts ahead of the vehicle as speed rises.	10
Top Camera Settings → Min / Max Orthographic Size	The view size, which grows with speed.	7.5 / 12.5

The mode foldouts: each Use … Camera Mode toggle decides whether the C key can reach that mode. Occlusion Settings sits below them.

Orbit

Players can orbit the camera in TPS and hood modes:

Mouse or touch: drag on the screen. The drag is picked up by the Drag (Orbit) panel in Prefabs/UI/RCC_Canvas.prefab, so the scene needs the RCC Canvas (Tools → BoneCracker Games → Realistic Car Controller → Create → UI → Add RCC Canvas To Scene).
Gamepad: use the right stick. The camera recentres 2 seconds after you release the stick. Gamepad orbit is ignored while Mobile Controller Enabled is on.

New in V6: You can orbit with the gamepad right stick (the gamepad binding of the Camera/Orbit action). Turn it off with Use Gamepad Orbit.

Orbit & Zoom Settings foldout:

Inspector label	What it does	Shipped default	Range
Use Orbit in TPS Mode	Allows orbiting in TPS mode.	On	—
Use Orbit in Hood Mode	Allows orbiting in hood mode.	On	—
Use Gamepad Orbit	Allows the right stick to orbit.	On	—
Min Orbit Y / Max Orbit Y	Vertical orbit limits, in degrees.	-10 / 55	-90 – 90
Orbit X Speed / Orbit Y Speed	Orbit speed.	100 / 100	—
Orbit Reset	After a mouse or touch orbit, returns the camera to its default position 2 seconds after the last drag, once the vehicle is doing 25 km/h or more.	On	—

Occlusion

With Occlusion Settings → Use Occlusion on (shipped on), the camera checks the line from the vehicle to the camera against Occlusion Layer Mask. Trigger colliders and the vehicle's own colliders are ignored. When something blocks the line:

In TPS mode, the camera moves in front of the obstacle.
In WHEEL and CINEMATIC modes, the camera switches back to TPS.
In FIXED mode, the fixed camera moves to a new position.

Untick layers in Occlusion Layer Mask that shouldn't push the camera, such as foliage or small props.

Hood and Wheel Camera Setup

Hood camera:

Select the vehicle in the scene.
Select Tools → BoneCracker Games → Realistic Car Controller → Create → Cameras → Add Hood Camera To Vehicle.
Move the new RCC_HoodCamera child to the driver's eye position, facing forward (+Z).

The hood camera prefab has a Rigidbody and a ConfigurableJoint. The menu connects the joint to the vehicle's Rigidbody for you.

Wheel camera:

Select the vehicle in the scene.
Select Tools → BoneCracker Games → Realistic Car Controller → Create → Cameras → Add Wheel Camera To Vehicle.
Move and rotate the new WheelCamera child to where you want the view, for example next to the front-left wheel.

Each menu shows a dialog if you haven't selected an RCC vehicle, or if the vehicle already has that camera. Both menus support undo. To apply the change to every copy of the vehicle, apply it to the prefab.

Switching Modes from Code

RCC.ChangeCamera() cycles to the next available mode, which is the same as pressing C. RCC_Camera.ChangeCamera(RCC_Camera.CameraMode) jumps straight to one mode without checking whether that mode is set up.

C#

using UnityEngine;

public class CameraModeButtons : MonoBehaviour {

    // Hook to a UI Button. Cycles to the next available mode.
    public void NextCamera() {

        RCC.ChangeCamera();

    }

    // Hook to a UI Button. Jumps straight to the top-down view.
    public void TopView() {

        RCC_Camera rccCamera = RCC_SceneManager.Instance.activePlayerCamera;

        if (rccCamera)
            rccCamera.ChangeCamera(RCC_Camera.CameraMode.TOP);

    }

}

Read the current mode with rccCamera.cameraMode.
