I think all this stuff runs on Javascript. Half the time I have no idea what I'm doing here. If I showed you the plugin do you think you'd be able to figure out what's going on? you might need to understand Japanese though...
I don't speak Japanese, sorry! I do know javascript. Is the code in the client side of this the same stuff you're working with on your end? I'm not familiar with RPG maker's dev environment at all.
