How To Make The Camera Follow The Player In Unity 3d

Camera in Unity is the most important gameobject unless yous are making a UI-based game. If you lot don't get the photographic camera angle right the gameplay experience volition endure. Making a Unity photographic camera follow script is simple yet many people become it wrong. In Unity, the camera follow can be executed in three different ways. Which method to apply more often than not depends on the type of game you are making. In this post, we will run into how to implement the camera follow script in Unity properly with code samples.

Camera follow is mainly used in third person games like Batman. In those games, you can run into that the camera rotation and player rotation are kept carve up but the camera follows the thespian at a distance. This is because we demand to show how the character is moving with respect to its environment. In that location are two major means y'all tin implement camera follow in Unity. The method of implementation depends totally on the features of the player grapheme in your game.

Method 1: Making the camera every bit kid of the Gameobject

• Drag the photographic camera gameobject into the gameobject you want the photographic camera to follow.
• At present yous tin can set the camera view, distance, and bending.
• When the thespian gameobject moves the photographic camera follows the gameobject as the camera is a child of the player gameobject.

Simply there is ane outcome with implementing photographic camera follow in this manner. The problem comes when the gameobject rotates. This method is most effective in the case of second platformer games and First-person view.

When the parent object rotates, the kid rotates along with it. Then, when the role player gameobject rotates, the camera rotates along with it, sometimes making the view disturbed and skewed. This can pb to poor gameplay experience. It is often not advised to use this method unless y'all are very certain of your grapheme motion. So, it's recommended to use scripts to control the camera movement.

Method 2: Using Unity camera Follow script

Camera follow script can requite you smashing control over what transforms of a camera you want to modify based on player motion. A common method is to set up the initial view of the camera based on the role player and calculate the offset based on the initial Vector3 position. This offset is maintained to keep the view intact.

To calculate the start. Set your camera as required past adjusting the transform in the editor. This will exist your initial camera position. We will calculate the offset based on this in the script.

• Create a new script by proper name Camera_Follow in the project window using create>new C# script.
• Re-create and paste the lawmaking below in the script.
• Add the script to camera using add together component button in the inspector window or drag and drop the script to the camera.
• Elevate and drop the thespian gameobject to the Camera_Follow script.
• Run the game and the camera will follow the player.

          using UnityEngine; using Organisation.Collections; public course Camera_Follow : MonoBehaviour { public GameObject actor; private Vector3 offset; void Start () {     offset = transform.position - player.transform.position; } void LateUpdate () { transform.position = player.transform.position + kickoff; } }                  

Allow's see what the script does. We are initializing a public gameobject that will be our player. You can drag and drop your role player to the script in the editor window. Then we set an offset for the camera from the histrion. Yous can just identify the photographic camera in a position based on the required view. The script will summate the initial offset and maintain information technology when post-obit the role player. So in the LateUpdate function, we motion the camera based on the player position.

As you lot can run across in the script, we are only changing the transform of the photographic camera and not the rotation. So fifty-fifty if the role player rotates the rotation of the camera remains unchanged.

"Lateupdate" is used to avoid jittering movements. Late update executes subsequently the update role. And so, if the player moves in the update, nosotros can update the camera position after the player moves.

There is a small problem with the script higher up.

When the player jumps the camera jumps with the player, making the jump await unnatural. So rather than applying the consummate transform, it's better to utilise the exact axis. More often than not the player will be moving in the "xz plane". And then, update the camera position only based on X and Z axis. Here is the final script that you can use.

Final Camera follow script

                      using UnityEngine; using Organisation.Collections;  public class Camera_Follow : MonoBehaviour { public GameObject player; private Vector3 get-go; individual Vector3 newtrans;  void Commencement () {     outset.x = transform.position.ten - player.transform.position.x;     starting time.z = transform.position.z - player.transform.position.z;     newtrans=transform.position; //not taking y as we won't update y position.   } void LateUpdate () { newtrans.x= thespian.transform.position.x + offset.x; newtrans.z= player.transform.position.z + outset.z; transform.position = newtrans; }  }                  

If you lot are updating the camera position in the update role yous can meet that the player moves in and out of the scene if your game is running at a higher FPS. You might not run into this in every case but it's best to use "LateUpdate". If you still find it difficult, you tin but grab the nugget below from the Unity nugget store and solve all your Unity camera follow issues. You tin read more about the Unity update part in our other web log mail.

Method3: Implementing Camera Follow using Unity Cinemachine

With the release of Unity Cinemachine a lot of camera features have been inbuilt in the virtual camera. Permit's see how to make the camera follow the histrion using virtual Vcam in Cinemachine.

Step1: Install Unity Cinemachine

1. Go to Windows>Package Manager.
2. If yous are using Unity 2021 then select Packages: Unity Registry. You can skip this step for older versions.
3. Search Cinemachine and Install it.

Step2: Add together a virtual cam

1. In older versions of Unity, you volition run into a Cinemachine option on the main menu. For Unity 2021 this option is moved inside Gameobject.
2. Go to Cinemachine>Virtual camera.
3. This will add a Vcam to the scene and a Cinemachine brain to the main camera.
4. Nosotros need only one Vcam for this purpose.

Step3: Assign the actor to the Virtual Cam

1. Select the Virtual photographic camera in the Hierarchy window.
2. Become to the inspector window and find the CinemachineVirtualCamera component.
3. Drag and driblet your player to the follow option in the CinemachineVirtualCamera component.
4. In the body component select framing transposer.
5. Reduce ten, y, z damping in the torso component to reduce the delay in follow.

Play the game and the camera will follow the histrion. This method cannot be used if you accept multiple virtual cams for making cutscenes.

Using Photographic camera Follow script in Unity asset store

If you have downloaded whatever FPS avails or character controller assets before. Information technology might accept a script to make the camera follow the player. If non the asset below is the best camera controller in the assets store.

Camera Controller

Photographic camera Controller is super smooth and built for 3rd person games, 1st person games, and even strategy/MOBAs. Using 'camera motors', the Camera Controller is able to seamlessly transition from i view to another. You can even transition mid-play to give your game that AAA quality boost.

Feature rich, the Camera Controller supports off-eye 3rd person views, advanced view obstruction detection, character fading, photographic camera shakes, and lots more.
