GraphicsBuffer.Target.CopySource

Description

GraphicsBuffer can be used as a source for CopyBuffer.

The source buffer for Graphics.CopyBuffer or CommandBuffer.CopyBuffer must have CopySource target set. This target is most often combined with other target flags.

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();
    }
}
