This one's for moving:
servercmdshiftBrick(%client,X,Y,Z); // note: 1 Z is the height of a flat, use 3 Z for the height of a normal brick
in example,
servercmdshiftBrick(%client,1,0,3);
Shift the brick away 1 and up 3(3 is for the normal +/5 on keypad raise/lower, and 1 would be for flat(1/3) raise/lower.
Then of course you could
for(%i=0;%i<6;%i++){
servercmdshiftBrick(%client,1,0,3);
servercmdplantbrick(%client);
}
to place a staircase 5 studs high.
