You might be able to do something like this with a sliding door that's camoflagued into the wall. Oncontentstart -> Self -> SetRendering [_]
Oncontentstop -> Self -> SetRendering [X]
It wouldn't be the same. You would be able to see the actual sliding door itself, and the brick itself wouldn't appear to go anywhere, just disappear.
What I want is something that looks just like a 1x6x5 brick, even though the brick itself isn't being rendered. When the content starts, by default triggered by activating it, the brick appears to slide sideways, creating a scraping sound and booming when it stops.
As is, the best you can do is make an ordinary 1x6x5 brick that disappears for a few seconds and plays the manhole cover sound when activated.
