    Hi, I'm using this code to make sure that the camera (without cinemachine) follows the player and stays between y: 0.5 and 20
    Code (CSharp):
    1. transform.position = new Vector3(redBird.transform.position.x, Mathf.Clamp(redBird.transform.position.y, 0.5f, 20f), -11);
    But is it possible to do that with cinemachine? because the way that cinemachine follows the player is 1000x better.
    To be clear I want that cinemachine follows the player on the X and Y axis but when the player is at Y=20 or higher. The camera/cinemachine stays at his Y position but still follows the X position of the player. and when the player is under Y = 20 again the camera Y position is the same as the players Y position.

    I hope you understand what I'm trying to get if not please respond and I'll try it to explain again!

    You can use a CinemachineConfiner extension to confine the camera to remain inside a bounding shape.

    Alternatively, you can write a simple custom extension to apply your constraints to the camera. Here is an example of one that I had lying around that constrains the camera Z. You can copy it and make the appropriate modifications so that it does your Y clamping instead.
    Code (CSharp):
    1. using UnityEngine;
    2. using Cinemachine;
    3.  
    4. /// <summary>
    5. /// An add-on module for Cinemachine Virtual Camera that locks the camera's Z co-ordinate
    6. /// </summary>
    7. [SaveDuringPlay] [AddComponentMenu("")] // Hide in menu
    8. public class LockCameraZ : CinemachineExtension
    9. {
    10.     [Tooltip("Lock the camera's Z position to this value")]
    11.     public float m_ZPosition = 10;
    12.  
    13.     protected override void PostPipelineStageCallback(
    14.         CinemachineVirtualCameraBase vcam,
    15.         CinemachineCore.Stage stage, ref CameraState state, float deltaTime)
    16.     {
    17.         if (stage == CinemachineCore.Stage.Body)
    18.         {
    19.             var pos = state.RawPosition;
    20.             pos.z = m_ZPosition;
    21.             state.RawPosition = pos;
    22.         }
    23.     }
    24. }

    thanks, Gregoryl for the reply! I got it to work! :D

    For the people that also want this. follow these steps!
    1. Go to CM vcam, scroll down in the Inspector until you see

    2. Click on "(select)" and choose "Cinemachine Confiner"

    3. create an empty GameObject and add a Polygon Collider 2D

    4. Click on this button and make the collider the shape you want.

    5. Go back to your CM vcam and drag the empty GameObject in here: upload_2020-5-15_16-49-27.png

    6. Now it should work!

    small tip: enable "Is Trigger" in the Polygon Collider 2D so your player/GameObject doesn't get pushed out! upload_2020-5-15_16-51-33.png
