通过 Light Explorer 扩展,可以创建自定义版本的 Light Explorer 窗口。可以将这种扩展用于调整 Light Explorer 窗口的功能,以便处理可编程渲染管线 (SRP) 或者高清渲染管线的自定义光源。
在 Light Explorer 窗口中,可以看到场景中的所有光源并可编辑它们的属性。使用此扩展,可以通过多种方式扩展当前窗口。例如,可以执行以下操作:
要扩展 Light Explorer,可以继承自:
ILightingExplorerExtension
接口,然后覆盖 GetContentTabs
方法。DefaultLightingExplorerExtension
类(继承自 ILightingExplorerExtension
)。此类提供窗口中已经存在的所有内容。如果只希望覆盖选项卡的数量、每个选项卡的标题或要显示的光源,请使用此选项。要了解如何以这种方式扩展 Light Explorer,请参阅下面的示例。本节中的示例展示了如何扩展默认的 Light Explorer 类以仅显示光源的名称 (Name) 列,以及如何更改选项卡的数量。在您自己的实现中,可以根据需要覆盖任意数量的方法。
以下示例显示了光源的名称列:
using UnityEngine;
using UnityEditor;
[LightingExplorerExtensionAttribute(typeof(ExampleRenderPipelineAsset))]
public class SimpleExplorerExtension : DefaultLightingExplorerExtension
{
private static class Styles
{
public static readonly GUIContent Name = EditorGUIUtility.TrTextContent("Name");
}
protected override LightingExplorerTableColumn[] GetLightColumns()
{
return new[]
{
new LightingExplorerTableColumn(LightingExplorerTableColumn.DataType.Name, Styles.Name, null, 200), // 0: Name
};
}
}
以下示例仅显示光源的名称和启用状态,并隐藏 Emissive Materials 选项卡(仅显示 3 个选项卡,而不是 4 个)
using UnityEngine;
using UnityEditor;
[LightingExplorerExtensionAttribute(typeof(ExampleRenderPipelineAsset))]
public class ComplexLightExplorerExtension : DefaultLightingExplorerExtension
{
private static class Styles
{
public static readonly GUIContent Name = EditorGUIUtility.TrTextContent("Name");
public static readonly GUIContent Enabled = EditorGUIUtility.TrTextContent("Enabled");
}
protected override UnityEngine.Object[] GetLights()
{
return Resources.FindObjectsOfTypeAll<Light>();
}
protected override LightingExplorerTableColumn[] GetLightColumns()
{
return new[]
{
new LightingExplorerTableColumn(LightingExplorerTableColumn.DataType.Name, Styles.Name, null, 200), // 0: Name
new LightingExplorerTableColumn(LightingExplorerTableColumn.DataType.Checkbox, Styles.Enabled, "m_Enabled", 25), // 1: Enabled
};
}
public override LightingExplorerTab[] GetContentTabs()
{
return new[]
{
new LightingExplorerTab("Lights", GetLights, GetLightColumns, true),
new LightingExplorerTab("2D Lights", Get2DLights, Get2DLightColumns, true),
new LightingExplorerTab("Reflection Probes", GetReflectionProbes, GetReflectionProbeColumns, true),
new LightingExplorerTab("Light Probes", GetLightProbes, GetLightProbeColumns, true),
new LightingExplorerTab("Static Emissives", GetEmissives, GetEmissivesColumns, false),
};
}
}
下面列出了可用于扩展 Light Explorer 的类和方法:
ILightingExplorerExtension:
public virtual LightingExplorerTab[] GetContentTabs();
public virtual void OnEnable() {}
public virtual void OnDisable() {}
DefaultLightingExplorerExtension(继承自 ILightingExplorerExtension):
public virtual LightingExplorerTab[] GetContentTabs();
public virtual void OnEnable() {}
public virtual void OnDisable() {}
protected virtual UnityEngine.Object[] GetLights();
protected virtual LightingExplorerTableColumn[] GetLightColumns();
protected virtual UnityEngine.Object[] GetReflectionProbes();
protected virtual LightingExplorerTableColumn[] GetReflectionProbeColumns();
protected virtual UnityEngine.Object[] GetLightProbes();
protected virtual LightingExplorerTableColumn[] GetLightProbeColumns();
protected virtual UnityEngine.Object[] GetEmissives();
protected virtual LightingExplorerTableColumn[] GetEmissivesColumns();
