GraphicsBuffer.Target.CopyDestination

描述

GraphicsBuffer 可以用作 CopyBuffer 的目标。

用于 Graphics.CopyBuffer 或 CommandBuffer.CopyBuffer 的目标缓冲区必须设置 CopyDestination 目标。此目标通常与其他目标标志结合使用。

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        // create a source index buffer and set data for it
        var src = new GraphicsBuffer(
            GraphicsBuffer.Target.Index | GraphicsBuffer.Target.CopySource,
            3, 2);
        src.SetData(new ushort[] {1, 10, 100});
        // create a destination index buffer and copy source into it
        var dst = new GraphicsBuffer(
            GraphicsBuffer.Target.Index | GraphicsBuffer.Target.CopyDestination,
            3, 2);
        Graphics.CopyBuffer(src, dst);

        // check the copied data
        var got = new ushort[3];
        dst.GetData(got);
        Debug.Log($"copied data: {got[0]}, {got[1]}, {got[2]}");

        // release the buffers
        src.Release();
        dst.Release();
    }
}
