Was talking to a few peeps about blockland's state system. It appears to not work like intended (client sided prediction), and since it is controlled purely server sided, We thought it would be a good idea to allow modders to play animations on images through a script. In such fashion:
%player.playImageSequence(%mountPoint, %sequence);
It could be done a few other ways, but this is about all I have to say. It is a much better method than having to use multiple images or the ammo states.
