Using two buffers (what you were initially doing) is actually correct. Using a single buffer causes a race condition, as you are reading a value that might or might not already have been modified by another thread. In fairness, this is not too important for something like Boids, as changes from one frame to the next are going to be small, but it is still wrong. Sorry! | |

As far as I can tell, your code is already sending the array correctly in the buffer.SetData(_flockAI) line. Could you elaborate as to what specific problem you are having? Also, I am curious as to why you are putting the same data into two separate buffers. That is, you could just iterate over the dataBuffer inside of the compute shader, as long as you are only writing into a single position from each thread.
