Totally understand! Just figured I'd offer a solution to at least one of the things you were asking about. I'm looking into the other part currently.
OKAY, after MUCH scrolling through this thread, I got it working. That being said: It required MULTIPLE strange workarounds:
1. editing the .js file. using the method outlined by
in an earlier reply, as well as editing the line of code : ImageManager.loadBitmap('img/overlays' + '/', name + "_" + i) : To look exactly as I just wrote it.
2. It requires having the organized files TURNED ON in the orange overlay plugin.
3.It requires you to have the animated layer turned on upon map entry.
4. It requires you to name the files in odd ways that aren't explained in the plugin help very well (i figured it out by following the string of errors I got in the play test)
5. It requires you to tie a common event with a conditional branch to the switch you want to use. And in that common event you need to TURN OFF the animation via the plugin command, and set the layer of your choice to a standard image in the specific folder.
Basically, there is no easy way to make this work, from what I can find. And there are probably other things out there that can accomplish what you want OR we can see if the creator of this plugin can implement a more reliable system. This also does not include all the MANY possible complications it might run into with OTHER PLUGINS. Honestly depending on what you're trying to do there may be a MUCH better solution.
Either way, this is what I got:
