用指针传入Jobs操作对于外部类型为传统数据类型的集合来说效率是比较高的，以下是示例代码：
using System;
using System.Runtime.InteropServices;
using Unity.Jobs;
using Unity.Burst;
using Unity.Collections.LowLevel.Unsafe;
using UnityEngine;
public class TestClass : MonoBehaviour
{
unsafe struct TestJob : IJobParallelFor
{
[NativeDisableUnsafePtrRestriction, NoAlias] public Vector3* vecs;
public void Execute(int i)
{
vecs[i] = vecs[i] * 2f;
}
}
private GCHandle mGCHandle;
private Vector3[] mVectors;
private void Start()
{
mVectors = new Vector3[4];
Array.Fill(mVectors, Vector3.one);
mGCHandle = GCHandle.Alloc(mVectors, GCHandleType.Pinned);
unsafe
{
var vectorPtr = (Vector3*)mGCHandle.AddrOfPinnedObject().ToPointer();
var job = new TestJob()
{
vecs = vectorPtr,
};
var jobHandle = job.Schedule(4, 2);
jobHandle.Complete();
}
foreach (var item in mVectors)
{
Debug.Log(item);
}//2,2,2...
mGCHandle.Free();
}
}
