The SetCounterValue method is used to set the counter value of a GPU buffer. This is particularly useful when working with append or consume buffers in compute shaders, where you need to explicitly manage the counter value to control the number of elements processed or generated.
To use the SetCounterValue method, you need to have an instance of the GpuBuffer class. Call this method with the desired counter value as a parameter. This method is typically used in scenarios where you need to reset or initialize the counter value before dispatching a compute shader.
// Create a GPU buffer with a specific usage flag
GpuBuffer buffer = new GpuBuffer(10, GpuBuffer.UsageFlags.Append);
// Set the counter value to 0 before using the buffer in a compute shader
buffer.SetCounterValue(0);
// Now the buffer is ready to be used in a compute shader
ComputeShader.Attributes.Set("buffer", buffer);
ComputeShader.Dispatch();
