Closesource | The source buffer. |
dest | The destination buffer. |
Copies the contents of one GraphicsBuffer into another.
The GPU copies the buffer contents efficiently.
Total buffer sizes (i.e. count multiplied by stride) must match between source and destination buffers. The source buffer must have a GraphicsBuffer.Target.CopySource target flag, and the destination buffer must have a GraphicsBuffer.Target.CopyDestination target flag.
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(); } }
