要隐藏游戏对象，使用SetActive函数并传递true/false来显示/隐藏它。is激活和取消激活游戏对象：

public GameObject modelA;
public GameObject modelB;

void Update()
{
    OVRInput.Update(); 

    if (OVRInput.Get(OVRInput.Button.One))
    {
        //Hide model A
        modelA.SetActive(false);

        //Show model B
        modelB.SetActive(true);
    }
}

如果你不想激活/取消激活游戏对象，只需启用/禁用MeshRenderer组件：

public GameObject modelA;
public GameObject modelB;

void Update()
{
    OVRInput.Update(); 

    if (OVRInput.Get(OVRInput.Button.One))
    {
        //Hide model A
        modelA.GetComponent<MeshRenderer>().enabled = false;

        //Show model B
        modelB.GetComponent<MeshRenderer>().enabled = true;
    }
}

如果你不想使用Oculus特定的依赖项（如OVR），你可以使用UnityEngine.XR.InputDevice，它应该是通用的

List<InputDevice> devices = new List<InputDevice>();
InputDevices.GetDevicesWithCharacteristics(InputDeviceCharacteristics.Controller |
        InputDeviceCharacteristics.TrackedDevice |  InputDeviceCharacteristics.Right,
        devices);
foreach (var item in devices)
{
    List<InputFeatureUsage> l = new List<InputFeatureUsage>();
    item.TryGetFeatureUsages(l);
    bool resBool;

    foreach (var i in l)
    {
        // I guess there could be a more elegant solution here.
        if (i.name == "TriggerButton")
        {
            item.TryGetFeatureValue(i.As<bool>(), out resBool);
            if (resBool) {
                modelA.GetComponent<Renderer>().enabled = true;
                modelB.GetComponent<Renderer>().enabled = false;
            } else {
                modelA.GetComponent<Renderer>().enabled = false;
                modelB.GetComponent<Renderer>().enabled = true;
            }
        }
    }
}
