    I was following a tutorial on youtube to remake angry birds and it used Cinemachine Camera to follow the player and enemies. However when it zooms out, the camera pans super low on the Y axis and looks like this.

    I would much rather have it pan upwards. than to go beneath the ground like this. I tried writing a script to keep the position locked at 0 but it doesn't work. I used Debug.Log() to check that my code is running and it is.

    Basically how can I keep the camera from going below a Y of 0.
    Thank you

    You can write a custom CM extension for the vcam. Here is one that locks the camera Y to a fixed position. You can modify it to implement a minimum value 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 Y co-ordinate
    6. /// </summary>
    7. [SaveDuringPlay] [AddComponentMenu("")] // Hide in menu
    8. public class LockCameraY : CinemachineExtension
    9. {
    10.     [Tooltip("Lock the camera's Y position to this value")]
    11.     public float m_YPosition = 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.Finalize)
    18.         {
    19.             var pos = state.RawPosition;
    20.             pos.y = m_YPosition;
    21.             state.RawPosition = pos;
    22.         }
    23.     }
    24. }
    25.
