ClosestPointCommand

struct in UnityEngine

切换到手册

描述

Struct used to set up a closest point command to be performed asynchronously during a job.

When you use this struct to schedule a batch of closest commands, they are performed asynchronously and in parallel to each other. The results of the closest points are written to the results buffer. Because the results are written asynchronously, the results buffer cannot be accessed until the job has been completed.

命令缓冲区中索引 N 处的命令的结果会存储在结果缓冲区中索引 N 处。

using UnityEngine;

public class ClosestPoint : MonoBehaviour { private void Start() { var collider = new GameObject().AddComponent<BoxCollider>(); // Perform a single closest point using ClosestPointCommand and wait for it to complete // Set up the command and result buffers var results = new NativeArray<Vector3>(1, Allocator.TempJob);

var commands = new NativeArray<ClosestPointCommand>(1, Allocator.TempJob);

commands[0] = new ClosestPointCommand(Vector3.one * 5, collider.GetInstanceID(), Vector3.zero, Quaternion.identity, collider.transform.lossyScale);

// Schedule the batch of closest points JobHandle handle = ClosestPointCommand.ScheduleBatch(commands, results, 1, default(JobHandle));

// Wait for the batch processing job to complete handle.Complete();

// Copy the result. If the point is inside of the Collider, it is returned as a result Vector3 closestPoint = results[0];

// Dispose of the buffers results.Dispose(); commands.Dispose(); } }

rotationThe rotation of the Collider.
scaleThe global scale of the Collider.
