Re: Can't publish laser data

Hi

Are you using an older version of Player? I believe that the size of the
data was deprecated in Player 2.1 and is now calculated. If you are using
player 2.0.5 or earlier I think you will need to pass the size into this
function, but most of the example you will have seen were probably written
for Player 2.1 or Player 3.
