[1.16.1] Batching block state change

[dwilby]

In my mod I am changing the state of a large number of blocks every so often. I have noticed that with the greater number of blocks that I change the state, the laggier it gets. I'm currently calling world.setBlockState for every block I want to change. Is there a way I can batch block state updates to the world?

You could try looking at how the vanilla /fill command does it. I'm not sure how optimised it is.
