Limos linked to the script, it just needs to be updated/downgraded to whatever server version you are using if it does not work in its present state. The main problem here is you never mentioned which server version you are using and are the sources for that server version freely available. The rarer the server the less likely someone would be able assist you so that is also something you need to be mindful of.I know this is an old post, but I am looking for something I think may be similar..
A tile that moves in a fixed location
No action or command needed to make it move, it just does on its own.
Like old school Zelda games where the floor moved left and right and if you missed it, you died.
