ClosestPointCommand

描述

用于设置在作业期间异步执行的最近点命令的结构体。

当您使用此结构体来安排一批最近点命令时，它们会异步执行，并且彼此并行。最近点的结果被写入结果缓冲区。由于结果是异步写入的，因此在作业完成之前无法访问结果缓冲区。

命令缓冲区中索引为 N 的命令的结果存储在结果缓冲区中索引为 N 的位置。

        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();
