另请参阅：GizmoType、DrawGizmo。

using UnityEngine;
using UnityEditor;

// Draw an image above the light when the light is not selected
// The icon has to be stored in Assets/Gizmos

public class ExampleScript : MonoBehaviour
{
    // Draw an image above the light when the light is not selected
    [DrawGizmo(GizmoType.NotInSelectionHierarchy | GizmoType.Pickable)]
    static void drawGizmo1(Light light, GizmoType gizmoType)
    {
        Vector3 position = light.transform.position;

        Gizmos.DrawIcon(position + Vector3.up, "ninja.jpg");
    }

    // Place a red sphere around a selected light.
    // Surround the sphere dark shaded when not selected.
    [DrawGizmo(GizmoType.Selected | GizmoType.NonSelected)]
    static void drawGizmo2(Light light, GizmoType gizmoType)
    {
        Vector3 position = light.transform.position;

        if ((gizmoType & GizmoType.Selected) != 0)
        {
            Gizmos.color = Color.red;
        }
        else
        {
            Gizmos.color = Color.red * 0.5f;
        }
        Gizmos.DrawSphere(position , 1);
    }
}

参数

描述

同上。drawnGizmoType 决定了我们绘制辅助图标所必须面向的对象类型。

如果 drawnGizmoType 为 null，该类型将由绘制辅助图标方法的第一个参数决定。 如果 drawnGizmoType 不为 null，该类型必须与第一个参数的类型相同或是其子类型。
