Question

对于SpherePointer，我有一个与this类似的问题。

使用NuGet for Unity收购的MRTK 2.2，我几乎在每一帧都收到此警告：

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，但是我对如何在GrabPointer预制件上做到这一点感到困惑。

此预制件已附加SpherePointer脚本，但不会在检查器中显示SceneQueryBufferSize属性，因为SpherePointer的自定义检查器（ShperePointerInspector.cs）无法公开它。

            serializedObject.ApplyModifiedProperties();
        }
    }

感谢朱莉娅

由于我无法在项目中修改SpherePointerInspector.cs，因为MRTK是从NuGet获取的，并且没有实际的.cs文件可编辑。这是我在MRTK 2.3发布之前作为临时解决方案提出的解决方案。

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

MySpherePointer.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
{
}

MySpherePointerInspector.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个对撞机？
