Help with emmiters?

[Exoyo]

Ok, so some of you may know, I am working on my Laser Tag Arena V.3.  I just finished part of my door, but I need a little help with the emmiters and colors going back.  So I put 1x1 bricks on top of eachother and named them and such, and then with a bricks next to the door will turn a pattern of bricks red while at the same time having Laser A pointing south.  But after a prompt comes up and says yes, the bricks dissapear, so there is an entrance.  But when they come back the red bricks with the lasers stay as they were.  Though, they were supposed to turn back to black.  So I neede to know how to make the red laser bricks turn black when they reappear, and how to make the laser stay south.  Thank you.

Come on guys, I know youy know this, and I need to go on with this part of the Laser Tag.   Just tell me how when the red bricks re appear that they are black and the laser is gone, and then when i click the thing that turns it red and brings the lasers back to make the lasers face south

You forgot the one rule of lasers...
To make South, set the S in the wrench menu

TO MAKE IT BLACK: Turn the brick black
Basically onwhatever -> Namedbrick -> Laserbrick -> Setcolor ->

I know, but when i click a certain brick it turns a pattern of bricks red, and puts laser a out.  I put south on the brick that turns red and has the laser, but with the brick i click to make the pattern it eventually makes all the bricks to the entrance dissapear, which i want.  But when they come back they are still red and have the laser.  I want it to turn back to black, and the laser to go away.  Thats what i want to know is how to change it all back to0 black and no laser when it reappears.
