Player Detector (MiscPeripherals)

The Player Detector is a block from MiscPeripherals which, when right-clicked, will output the username of the player who clicked it to a Computer or Advanced Computer placed adjacent to it.

Crafting and Usage.

The following program will detect when the player detector has been right-clicked by a player and will the output the player's usename.

while true do --Will keep logging players as the program runs
  a, b = os.pullEvent(player) --Will log the type of event (player) and the username
  print(b)
  end

The event that happened (player) is stored to the variable "a", and the player's name is stored to the variable "b". (Text after double dash is a comment and will be ignored, and won't run) There are many possible usages for such a block, e.g. a door that would only open if certain players right-click the Player Detector. The Detector is not entirely secure, however, as it can be easily broken in unprotected areas.

Example using above code for Player Detecting Door:

while true do   --Will keep running the following code every time it reaches the end
  term.clear()   --Will clear the screen
  term.setCursorPos(1,1)   --Will set Cursor at top left corner
  print("Waiting for player..")
  a,b=os.pullEvent(player)
  if b=="Notch" then   --If the player "Notch" (configurable) interacts...
    redstone.setOutput("right",true)   --...the computer will output redstone from the right side (configurable)
    sleep(2.5)   --Will delay the rest of the code by 2.5 seconds (also configurable)
    redstone.setOutput("right",false)   --Willl stop outputting redstone from the right side
    end   --If statement ends here
  end   --While loop ends here, and start all over
