It's too late for me to making sense out of things :/
Actually, that woudn't even work. The client's variables go away after they leave, if the person leaves the server and the vars are saved to the client, the vars would be gone, which brings me back to my first point
If you did that, you would need to event the variable to save for ever client that joined, and that's more trouble than it's worth.
You would have to event it like
Onmingamejoin>client>ifvalue>[<var:cl:bl_id>]==[whatever]
Onvariabletrue>client>setvar>blah blah blah
Onvariabletrue>client>setvar>blah blah blah
blah blah blah
Onminigameleave>client>ifvalue>[var:cl:bl_id>]==[blah blah blah]
Onvariabletrue>namedbrick>setvar>blah blah blah
Onvariabletrue>namedbrick>setvar>blah blah blah
blah blah blah
And do that for every client that joined the server.
