screenPoint | 屏幕上的投射起始点。 |
hitResults | 生成的 XRRaycastHit 列表。 |
trackableTypeMask | 要对其投射射线的 TrackableType 的可选遮罩。 |
从屏幕点对选定的可跟踪信息(例如,平面和特征点)投射射线。
从屏幕位置对场景中选定的可跟踪信息投射射线。trackableTypeMask
默认为 TrackableType.All。
using System.Collections.Generic; using UnityEngine; using UnityEngine.Experimental.XR;
public class RaycastExample : MonoBehaviour { public XRRaycastSubsystem xrRaycast; private List<XRRaycastHit> m_RaycastHits = new List<XRRaycastHit>();
private void Update() { if (Input.GetMouseButton(0)) { // Only raycast against feature points and the exact plane boundries var hitMask = TrackableType.FeaturePoint | TrackableType.PlaneWithinPolygon; if (xrRaycast.Raycast(Input.mousePosition, m_RaycastHits, hitMask)) { Debug.Log("Hit something!"); } } } }
ray | 要使用的 Ray。 |
depthSubsystem | 要对其投射射线的 XRDepthSubsystem。可能为 /null/。 |
planeSubsystem | 要对其投射射线的 XRPlaneSubsystem。可能为 /null/。 |

trackableTypeMask | 要对其投射射线的 TrackableType 的可选遮罩。 |
pointCloudRaycastAngleInDegrees | 当对特征点投射射线时,使用此角度投射锥体。 |
使用 ray
对选定的可跟踪信息(例如,平面和特征点)投射射线。
使用此方法对场景中选定的可跟踪信息投射射线。trackableTypeMask
默认为 TrackableType.All。
当对 TrackableType.FeaturePoint 投射射线时,Unity 将使用由 pointCloudRaycastAngleInDegrees
定义的锥体。默认为 5 度。
