如何修改 GrabPointer 预制件以允许场景中超过默认的 64 个碰撞器？

Question

我有一个与 this 类似的问题，但是对于 SpherePointer。

使用 NuGet for Unity 获取的 MRTK 2.2，几乎每一帧我都会收到此警告：

Maximum number of 64 colliders found in SpherePointer overlap query. Consider increasing the query buffer size in the pointer profile.
UnityEngine.Debug:LogWarning(Object)
Microsoft.MixedReality.Toolkit.Input.SpherePointerQueryInfo:TryUpdateQueryBufferForLayerMask(LayerMask, Vector3, QueryTriggerInteraction)
Microsoft.MixedReality.Toolkit.Input.SpherePointer:OnPreSceneQuery()
Microsoft.MixedReality.Toolkit.Input.FocusProvider:UpdatePointer(PointerData)
Microsoft.MixedReality.Toolkit.Input.FocusProvider:UpdatePointers()
Microsoft.MixedReality.Toolkit.Input.FocusProvider:Update()
Microsoft.MixedReality.Toolkit.<>c:<UpdateAllServices>b__63_0(IMixedRealityService)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:ExecuteOnAllServices(IEnumerable`1, Action`1)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:ExecuteOnAllServicesInOrder(Action`1)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:UpdateAllServices()
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:Update()

我能够使用 @Julia's 响应成功删除 PokePointer 的类似警告，但我不知道如何为 GrabPointer 预制件执行此操作。

此预制件附加了 SpherePointer 脚本，但 SceneQueryBufferSize 属性未在检查器中公开，因为 SpherePointer 的自定义检查器 (ShperePointerInspector.cs) 未公开它。

好问题！看起来你真的发现了一个错误。请暂时使用以下代码解决此问题，我们将很快 post 进行修复。跟踪这个的问题在这里：issue 6878

            serializedObject.ApplyModifiedProperties();
        }
    }

谢谢朱莉娅，

因为我无法在我的项目中修改 SpherePointerInspector.cs，因为 MRTK 是从 NuGet 获得的，没有实际的 .cs 文件可以编辑。这是我在 MRTK 2.3 发布之前作为临时解决方法提出的解决方案。

我在 GrabPointer.prefab 的副本上用我的 SpherePointer.cs 替换了 SpherePointer.cs。

我的SpherePointer.cs

using Microsoft.MixedReality.Toolkit.Input;

/// <summary>
/// This class exists soley to expose SpherePointer.queryBufferPointerSize which is
/// masked by the default SpherePointerInspector.
/// </summary>
public class MySpherePointer : SpherePointer
{
}

我的SpherePointerInspector.cs

using Microsoft.MixedReality.Toolkit.Input;
using UnityEditor;

/// <summary>
/// This class exists soley to expose SpherePointer.queryBufferPointerSize which is
/// masked by the default SpherePointerInspector.
/// </summary>
[CustomEditor(typeof(MySpherePointer))]
public class MySpherePointerInspector : SpherePointerInspector
{
    private SerializedProperty sceneQueryBufferSize;
    private bool hiddenSpherePointerFoldout = true;
    protected override void OnEnable()
    {
        base.OnEnable();
        sceneQueryBufferSize = serializedObject.FindProperty("sceneQueryBufferSize");
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        hiddenSpherePointerFoldout = EditorGUILayout.Foldout(hiddenSpherePointerFoldout, "Hidden Sphere Pointer Settings", true);

        if (hiddenSpherePointerFoldout)
        {
            using (new EditorGUI.IndentLevelScope())
            {
                EditorGUILayout.PropertyField(sceneQueryBufferSize);
            }
        }

        serializedObject.ApplyModifiedProperties();
    }
}

如何修改 GrabPointer 预制件以允许场景中超过默认的 64 个碰撞器？

How do I modify the GrabPointer prefab to allow for more than the default 64 colliders in a scene?
