This anchor shows the first downwards collider intersection. Depth pass lines appears green, depth fail, red.
要使用此示例,请将此脚本附加到您希望向其显示锚点的对象:
using UnityEngine; using UnityEditor;
[ExecuteInEditMode] public class SampleAnchor : MonoBehaviour { void OnDrawGizmosSelected() { Ray ray = new Ray(transform.position, Vector3.down); RaycastHit hit; if (Physics.Raycast(ray, out hit)) { Handles.color = Color.green; Handles.zTest = UnityEngine.Rendering.CompareFunction.LessEqual; Handles.DrawLine(transform.position, hit.point); Handles.DrawWireDisc(hit.point, hit.normal, 0.5f);
Handles.color = Color.red; Handles.zTest = UnityEngine.Rendering.CompareFunction.Greater; Handles.DrawLine(transform.position, hit.point); Handles.DrawWireDisc(hit.point, hit.normal, 0.5f); } } }
