Using 3D confiners for a 2D game

Unity Engine
1

I’m working on a 2D platformer project and instead of parallaxing scripts I was just using the perspective camera.

For confining I implemented 3D box collider confiners on a specific plane on the Z-axis.

Is this an acceptable use? Would I run across any problems later on due to this implementation?

That will work. It might be a little more efficient to do it with a custom extension on the vcam, such as this one:

using UnityEngine;
using Cinemachine;

/// <summary>
/// An add-on module for Cinemachine Virtual Camera that locks the camera's Z co-ordinate
/// </summary>
[SaveDuringPlay] [AddComponentMenu("")] // Hide in menu
public class LockCameraZ : CinemachineExtension
{
    [Tooltip("Lock the camera's Z position to this value")]
    public float m_ZPosition = 10;

    protected override void PostPipelineStageCallback(
        CinemachineVirtualCameraBase vcam,
        CinemachineCore.Stage stage, ref CameraState state, float deltaTime)
    {
        if (stage == CinemachineCore.Stage.Body)
        {
            var pos = state.RawPosition;
            pos.z = m_ZPosition;
            state.RawPosition = pos;
        }
    }
}

Excellent! I’ll implement this right away and have a look. Thanks lots!
