설명

Subscribe to this event to handle object placement in the SceneView.

This delegate is invoked by PlaceObject when drag and dropping objects from the Hierarchy and Project views.

using UnityEditor;
using UnityEngine;

static class PlaceObjectExample { static readonly Plane s_GroundPlane = new Plane(Vector3.up, Vector3.zero);

[InitializeOnLoadMethod] static void InitPlaceObjectHandler() { HandleUtility.placeObjectCustomPasses += PlaneRaycast; }

// In this example, we register a plane at the scene origin to test for object placement. static bool PlaneRaycast(Vector2 mousePosition, out Vector3 position, out Vector3 normal) { Ray worldRay = HandleUtility.GUIPointToWorldRay(mousePosition); float distance;

if (s_GroundPlane.Raycast(worldRay, out distance)) { position = worldRay.GetPoint(distance); normal = s_GroundPlane.normal; return true; }

position = Vector3.zero; normal = Vector3.up; return false; } }
