I'm still learning a few things from the Blockland forum, thx for letting me know
If you want to make bricks be physical (hehe) you must name them all, then put on bricks
onactivate >> namedbrick (namedbrickhere) >> fakekillbrick (0) (0) (0) (10)
the 0's is what direction it will fly in, and the 10 is how long the brick will be fakekilled for.
You might get an error like toomanyeventsatonce(on activate), you just have to change that by when you start a server, in the options.
